My name is , engaged in electrical equipment repair work has been 5 years. Since years to company, has been working for more than two years. From entering the company has been engaged in substation operation and maintenance and management. Has participated in and organized a high-pressure measurement and relay protection setting and calibration; reactive power compensation and voltage setting; DC screen inspection and maintenance; substation secondary circuit fault and processing; high-voltage cabinet failure and treatment; high-voltage cable head Production and processing; substation in the spring and autumn all overhaul and maintenance; outdoor high voltage overhead line fault handling and maintenance. I always assiduously with high-voltage technology to improve the operating rate of the combination, and actively study the principles of high-voltage equipment and maintenance experience, and insist on constantly improve their theoretical and practical skills to solve the substation running a lot Technical problems, in order to improve the power transmission and transmission equipment operating rate and laid a good foundation. Substation is the power system in the power of the voltage and current transformation, concentration and distribution of the place. In order to ensure the quality of electrical energy and the safety of the equipment, voltage regulation, power flow and voltage distribution, distribution of power, current and power in each node and branch of the power system and control of transmission and distribution lines and Protection of major electrical equipment. Now substation over the past two years have experienced the work summarized as follows:
1, vacuum circuit breakers in the daily operation of the fault types and treatment.
November 8, 20xx due to power company line fault on my company large power outage for 3 hours. After receiving the notice, we press the power substation regular power outage procedures for power outages. When the power company to deal with failure after transmission, according to power transmission step. Then found the 35KV main transformer vacuum circuit breaker refused to close, this is my company has just put into operation for two months the first time the substation problems, our company substation 35KV high voltage cabinet vacuum circuit breaker is applied Chint ZN85-40.5 circuit breakers. In the experimental state found after closing the circuit breaker command, closing electromagnet action, the core plunger will close the pawl top open, closing the spring release energy, driving the circuit breaker closing, but the circuit breaker interrupter can not be together brake. After analysis, indicating that mechanical failure has been excluded, indicating that the secondary line fault, found in the secondary auxiliary plug has a needle and control wire desoldering, vacuum breaker to deal with after closing, fault problem solving. Vacuum circuit breakers in the daily work of the most prone to failure to be summed up: 1. Positive air circuit breaker refused to sub (gate)
2. Vacuum circuit breaker body energy storage, energy storage motor stop 3. Vacuum interrupter interrupter can not be disconnected 2, the current transformer secondary open and deal with
* The end of the month, the power company came in February of the electricity details, with my company substation measured by the amount of difference 20xx2KW.h. I led the technical staff to conduct a comprehensive inspection of high-pressure measurement, due to limited conditions, failed to find fault problems. The company invited the power company metering and testing center substation secondary circuit test. The current transformer, voltage transformer, secondary voltage drop and secondary load, electric energy meter of 35KV and 10KV each switch cabinet are tested. In the power company equipment testing found 35KV high back-up protection of the terminal has an indirect open phenomenon. After processing, in the specified time with the power company metering center, the problem has been resolved. Current transformer CT primary winding number of turns is small, the use of a winding in series in the measured line, the secondary winding turns, and measuring instruments and relays and other current coil in series, measuring instruments and relays and other current coil impedance is very small , So the normal operation of CT is close to short-circuit state. CT secondary current size determined by the primary current, secondary current generated by the magnetic potential, is to balance the current magnetic potential. If the secondary open circuit, the impedance is infinite, the secondary current is equal to zero, the magnetic potential is equal to zero, can not balance the current generated by a magnetic potential, then a current will act on the excitation, the core serious saturation. Magnetic saturation increases the iron loss, CT fever, CT coil insulation will be burned by overheating. But also in the core to produce remanence, increasing the transformer error. The most serious is due to the magnetic saturation, alternating sine wave into a trapezoidal wave, the rapid changes in flux moment, the secondary coil will induce a high voltage, the peak up to several thousand volts, so high Of the voltage on the secondary coil and the secondary circuit, the person and equipment are a serious threat.
3, to complete the good leadership of the other basic and temporary work assigned.
Over the past year, I am learning and working in the gradual growth and maturity, but I know there are many deficiencies, such as lack of ability to work and innovation, lack of political theory to be improved and so on. In the future I will try to do the following, I hope the leadership and comrades of my supervision and guidance:
1, consciously strengthen the study, to the theory of learning, to professional knowledge learning, learning to colleagues around, and gradually improve their theoretical level and operational capacity.
2, to overcome the young gas impatient, so down to earth, improve work initiative, not afraid to do more things, not afraid to do small things, improve the practice in the bit to improve themselves.
3, continue to improve their political accomplishment, strengthen the sense of purpose of serving the people, and strive to become an outstanding national civil servants.
Time flies, blink of an eye to the company has been a year, feeling a lot, a lot of harvest. Into the City Electrical Equipment Co., Ltd., for me is a good opportunity for development, is also a good exercise and enhance their ability to various aspects of the opportunity. In this first special thanks to the leadership and colleagues to give me the strong support, care and help so that I can quickly adapt to the company's management system, and strive to do their jobs. Into the company, I seriously understand the company's development profile, learning the company's rules and regulations, familiar with the company's processes. At the same time, it is truly feel positive, inspiring corporate culture, so I benefited from. Now I work over the past year summarized as follows:
First, solid work
I entered the workshop from the sheet metal began to do chest box shell, can be said that the sheet metal shop is my first impression of the company. Have to say, in the sheet metal workshop a month, the master who gave me a good image, so I benefited.
Last September, I went into the assembly workshop internship, I deeply feel my colleagues work diligently, and strive to perfect the spirit. In the assembly workshop, I focus on access to relevant information, manuals, drawings and instructions to understand the operation of electrical equipment and principles, learning equipment layout, wiring, do row, the second line. Into the assembly plant began, I know that their burden is very heavy, I always remember this sentence to give others a bowl of water, they will have a bucket of water. Because I know that in order to become a qualified technician is not an easy task, as a technician not only to be able to deal with the requirements of customers, more importantly, to be able to solve the problems on the scene, on-site equipment operation Situation to be aware of.
In May this year, following the installation team to Panzhihua, I seize the time familiar with the drawings, construction plans, drawings, the construction site management, acceptance and other requirements. In the face of difficulties and problems, take the initiative to consult the leadership, and design units and construction units to communicate and coordinate relations, in order to smooth the work of the project. The actual work, due to some local civil engineering changes and drawings, resulting in the wall without leaving holes, bridge and pipe unreasonable, need to open or re-layout to take the line, increase the workload, and after the leadership communication has been resolved. Therefore, in future work, I will pay attention to relevant knowledge, so that their own from the civil, decoration, budget and other aspects of strengthening, good external coordination, and actively design units, construction units and government departments to communicate, to develop a good overall planning, Where the interests of the main companies.
Second, efforts to learn and progress
In the work, serious study, and constantly improve themselves, and the use of other time, learn more advanced knowledge. From the simplest manufacturing standards start to do a complete set of equipment, where both their own studious, but also inseparable from the workshop colleagues Q & A FAQ. From the old engineer who I not only learned a lot, but also gave me a lot of sentiment. For the first time I do equipment, colleagues not only help me carefully but also patiently explained to me, very grateful to colleagues for their help, but also in our culture so that the company better work with sufficient confidence.
Third, shortcomings and shortcomings
As I participated in the work soon, so in many ways the technology and experience are inadequate, the problems encountered, the problem can not be handled handy. In the future work, we must dare to solve and deal with problems encountered problems, never escape, humbly to the experienced technicians, the old workers to learn; In addition, the timely organization of lessons learned, the existence of doubt, do not understand the aspects are recorded Down, and seize the time to solve the problem, make a record, so that later encountered the same thing, can solve the problem faster. Conscientiously learn all kinds of knowledge, so that their future work, to better complete the leadership of the work and tasks assigned to make themselves more mature faster.
Fourth, self-evaluation
Although I participated in the production of labor and technology study time is only one year, but in the ideological and technical have been greatly improved and progress. Not only enrich the knowledge, but also to improve their management and business level, the most important thing is for their own work in the future, to better completion of the task to lay a good foundation.
Summing up the work of the past year, both achievements and deficiencies. In the future work, only continue to seriously sum up, found inadequate, and strive to correct, in order to get faster progress in order to better serve the company, realize the value of life.
In short, through a year of productive labor and technical learning, I thought and technically have been greatly improved and progress. That is, broaden the horizons, a wealth of knowledge, but also improve their management and operational level, the most important thing is for their own work in the future, to better completion of the task to lay a good foundation.
In the political and ideological aspects have also made great progress, I actively move closer to the party organization, through the cadre study, understanding of the social development of the new situation and new trends, deepened understanding and understanding of the Communist Party of China in the spirit of the 17th CPC National Congress Under the guidance of more efforts to achieve individual ideological progress and leap in the struggle more than.
Summed up the work of the past year, that there are many problems and shortcomings. In the future work, only the continuous careful summary, found deficiencies, correct shortcomings, individuals can get faster progress. I think I work well.
Time is always footsteps, how long a year? Three hundred sixty-five sunrise, three hundred sixty-five sunset only, in the alternation of sunrise and sunset in the past, look back this year's work And life full and half at a loss.
This year I am still in Beidaihe sanatorium overall renovation project is responsible for electrical work. In the first half of the main construction, electrical construction to do with the civil pipe buried and ground lightning protection work, electrical project construction team is the local construction company in Qinhuangdao, construction quality and the quality of the construction team in Beijing is not the slightest difference, the local quality inspection Department requirements are too low, so the first half of my identity is another professional quality inspectors, for their strict requirements but also to provide their own learning opportunities, in order to convince others of course, there are good reasons, professional aspectsShould have a solid professional knowledge.
This project has a special case, close to the beach, the ground is hard rock, which encountered two situations, one, the seaside corrosion is particularly heavy, the original design of all used galvanized steel pipe and welded steel pipe, the general situation Under the two management is the most durable, but not applicable at the beach, whether galvanized pipe or welded steel pipe bare in the air not more than two weeks above the thin layer of corrosion is a layer of light touch It peeling off. Brush off the anti-rust paint had no effect. Project supervision to me when drawing this point, the beginning of half-doubt. In the design of the consent of the ground only part of the strong power to pvc pipe, concrete pipes are also used galvanized steel pipe, summer and a half months after the suspension, the site reserved for structural columns, steel pipe surface is a thick one Layer rust, I am surprised I secretly delighted: really do not listen to the old man made a loss in sight, the experience is really useful ah! Second, because the basis of the following are all rock, lightning effect is not good, the original design lightning protection grounding Practices fail to meet the requirements of the standard value, and other building foundation is not connected to the case can only fill the ground electrode or add resistance reduction agent.
Beidaihe due to the suspension of the project a month and a half, but also because of the renovation project we went to Shanghai. Shanghai is a bustling city, surging in the city is the latest fashion, her architecture has its own unique style, we have seen in Shanghai, known as the Bund Building known as the Bund buildings, a taste of the past Far East Wall Street wind color . Bank of China, Peace Hotel, Customs House, HSBC Bank & .. These buildings are not from the same designer hand, is not built in the same period, but their architectural tones basic unity, the overall contour processing surprising coordination, Whether it is overlooking or wander in the meantime can feel a vigorous and vigorous, elegant and imposing manner. The short trip makes me realize that their vision of the narrow, lack of knowledge, personal small, Jinmao Tower, the Pearl of the Orient really is out of reach?
The second half of my work is mainly responsible for the room electrical pipeline laying and power supply and distribution programs, electrical piping laying should be very simple, but because the program is not sure the drawings imperfect, my role constantly transform, live doing some powerless. But better be regarded as a test of their own right, more opportunities for more growth.
Originally thought that the power supply program will be a good run, the fact once again taught me a lesson: underestimate the enemy will be beaten.Shanghai's design with this can not be used in the Beidaihe area, no way everything from scratch, knowledge is learned in a setback. years of work, life in contact with more and more 80 or 80, to see them one by one in their respective fields to show their mettle, ambitious look, inner panic arises spontaneously.
In the four years of university study, I continue to challenge themselves, enrich themselves, advancing with the times, all-round development of their own should have the ability.
In the study, I earnestly study specialized courses, study hard, study achievement is outstanding, has won two first-class scholarship, a second scholarship, a third scholarship, also won the honorary title of outstanding students .Digual learning combined with social practice, With a strong ability to learn and analyze and deal with problems, in addition, the computer also has the basic knowledge, economics, business management and other related professional knowledge.
In thinking, I am aggressive, have a higher ideological consciousness, advancing with the times, concerned about national affairs.
In life, I am lively and cheerful, patient, optimistic, and often communicate with teachers, and students get along well, helpful, good at listening to others opinions, brainstorming, a strong sense of responsibility and good interpersonal relationships, A wide range of friends, have good communication skills.
I am interested in a wide range of expertise is the sprint, long-distance running, has won the 200-meter sprint the second place of success, in the school to join the Taekwondo Association, many times to participate in college leagues, and referees with the relevant knowledge and technology,And actively participate in a series of school activities, such as the athletic meet aerobics, new performances and a number of public fund-raising activities, etc., which not only makes me enhance physical fitness, but also makes me more strong and confident. I have learned a number of ways of doing things, have better organizational coordination, but also accumulated some experience for the future work laid the foundation.
I realized that I still have a lot to learn, so in the future I will be optimistic about the work and study, so that their more comprehensive development.
With a certain career development prospects, will help me improve the relevant professional skills, and core competitiveness of the professional positions.
Graduated from Technical University of Electrical Engineering and Automation, outstanding academic performance during the school, has entered the tutor electrical automation laboratory for electrical component selection and functional testing, controller design and functional debugging, programming control and electrical systems Of intelligent control;
After graduation, the company entered the State Power Automation Co., Ltd., is responsible for product design and debugging, field equipment installation, commissioning and acceptance work for the hydropower station and power plants to provide monitoring equipment, proficient in the host computer and Under the machine system, various types of PLC and touch screen programming control; in the field during the service has repeatedly praised by customers, to work seriously responsible, good communication, coordination has a strong organizational skills and team spirit, lively and cheerful, optimistic progress; Motivated, diligent in learning can continue to improve their own ability and overall quality. In the future work, I will be full of energy, assiduously study the spirit to work hard and steadily improve their ability to work with the simultaneous development of enterprises.
This year is coming to an end, in order to be able to work better in the next year, sum up experience, adhere to the advantages and correct deficiencies, according to company requirements, summarized as follows: in a year's work, through the summary, although made some progress, A lot of shortcomings and deficiencies. As an electrical and mechanical workshop electrical technicians, in the production of work is only constantly sum up the lessons learned and found that in order to make their own faster progress.
First, in-depth, solid work
As an electrical technician in the electromechanical workshop of the coal preparation plant, my main responsibility is to be responsible for the management of electrical technology in the electromechanical workshop, to work out the maintenance arrangement of the electrical equipment and the corresponding management rules and technical operation measures, organize the staff to do well in the business training; Often in-depth site, continue to promote new technology and new technologies.
Over the past year, I have been working hard, fulfilling my duties seriously, constantly improving myself from the technical and management level, and have made great achievements in all aspects. I work in the workshop with the same below the master of the workers, equipment problems encountered actively to the scene to deal with failures, eliminate hidden dangers. Insist on the scene every day to check the operation of equipment, high and low voltage equipment for power supply and distribution; master production process of coal preparation to learn the principle of centralized control; understand the control signal routing layout, information transmission. Now many aspects have made great progress, for example: the communication 2 × × station system, the elevator running system, automatic control system concentrator, filter closed-loop control system, King configuration system, pressurized filter system, the main Plant and new plant coal washing system, from shallow to deep grasp the basic control structure and principle of the system. So I have a very thorough understanding of the production process of coal washing, and have learned the knowledge and the actual production of effective combination for the future to better theory with practice, better promote the production, better reduce the workers The master of the labor intensity, more effective to improve labor productivity, for enterprises and the community to create more benefits laid a solid foundation. Other aspects of meticulous improvement and completion of electrical safety regulations and measures to seriously monitor the implementation of the annual maintenance in the 11, through the replacement and overhaul of the transformer, but also learned a lot of things usually do not see, so I coal washing Plant electrical equipment with a deeper understanding.
Material plan to provide timely, comprehensive, accurate spare parts parameters is the guarantee of normal operation of the equipment, I am responsible for the electrical equipment materials plan to report work, at work, I ran the scene, check the problem, so that spare parts can be more comprehensive and reliable , To avoid the lack of spare parts and delay the status of production. And through the low-voltage power distribution room to find the problem, and other technical staff together proposed the transformation of low-voltage distribution room equipment plan, and through the production of selection, use, the basic solution to the production of spare parts for the purchase of passive, and Resulting in equipment failure problems. Low voltage power distribution room of the new plant are used in the domestic production of electrical components, AC contactor with the use of materials often aging, poor access to auxiliary early, the signal is not normal and so on, after the decision to use imported Siemens contactor to transform it, So far, basically solved the problem caused by the contactor accident occurred, reducing the accident rate, a substantial increase in the driving rate, to ensure the normal production of coal washing.
In the work, the first is strict on their own, do not allow the staff to do, their firm quit, for the field workers to set an example. In the implementation of the implementation of procedural measures, the strict on-site, the work of a number of measures do not quit. The illegal behavior of workers and non-standard behavior resolutely stop. In the production of security incidents and accidents affecting the production of serious organizational analysis, do not go through the motions, accountability does not take the form, so that the implementation of responsibility, education, alert everyone's purpose. The second is to consider the work of small, so that the overall balance, that is, there are safety education and specific work arrangements, taking into account the production and taking into account the electrical and mechanical and business, so that the face of all non-leakage control, the work done a layout, , There are checks. Third, pragmatic, through the daily study, and constantly improve their theoretical level, operational level, practical experience and personal qualities. Fourth, a solid work, the work does not remain on the surface, not afraid of difficulties, not afraid of wounding, truth-seeking results, and further improve their management level.
Second, join the technical innovation, never in innovation
In the work, seriously to the old comrades to learn, and constantly improve themselves, and use other time, learn more new knowledge. And actively participate in the plant plc program control system to the transformation, and achieved certain results, including the following: First, seriously involved in the flotation automation system, and basically mastered the flotation automatic control system, mastered the The new control system, learned to solve and deal with problems in ways and methods; followed by the thickener automatic control system transformation, the OMRON plc with updated understanding; Third, the design of the plant ash measurement system configuration screen Designed to make better use of gray instrument in the production, to make the configuration screen, you can use the unit time of the various instantaneous ash, the unit time to calculate the average ash to solve the ash analyzer average ash value The design and transformation of the chain of 302 chain-link protection procedures, and in the configuration screen to add 302 chain-link chain protection alarm, reducing the chain once the parking chain will be mistaken for a broken chain protector Motion problems, and solve the previous chain protection device action, the alarm can also start the car issue, reducing the electrician to determine the fault and solve the problem of processing time; Fifth, add the belt belt ash tester fault alarm device, the use of Ash measured ash content of the actual value, compared with the set percentage, when the ash over 12.00ash, that is audible and visual alarm (now only the optical signal, not the use of sound alarm), the other is now on the ash measuring instrument Adjustments are being made to meet actual production requirements. So that the driver in accordance with the production needs of the timely adjustment of ash to avoid excessive ash caused unnecessary losses.
Third, shortcomings and shortcomings
As the time to the coal preparation plant is still small, so in many aspects of technology and experience are inadequate, less problems encountered, the problem can not be handled handy. In the future work, we must adhere to run more than the scene, dare to find, solve and deal with problems encountered problems, never escape, humbly to the experienced veteran workers, the old master learning; In addition, the timely organization of lessons learned, Of the problem, do not understand the problems are recorded, and seize the time to resolve the deal, do a good job in the record in order to encounter the same problem in the future, can be faster to deal with the organization. Serious study of management methods and methods to make their own production organization in the future, to better complete the leadership of the work and tasks assigned. In previous work, consider the problem is often not comprehensive, do not consider the consequences of doing things, not only delayed their own, but also affected the others, in the future work and study, must strengthen the study to make themselves more quickly mature.
Fourth, self-evaluation
In short, through a year of productive labor and technical learning, I thought and technically have been greatly improved and progress. That is, broaden the horizons, a wealth of knowledge, but also improve their management and operational level, the most important thing is for their own work in the future, to better completion of the task to lay a good foundation.
In the political and ideological aspects have also made great progress, I actively move closer to the party organization, through the cadre study, understanding of the social development of the new situation and new trends, deepened understanding and understanding of the Communist Party of China in the spirit of the 17th CPC National Congress Under the guidance of more efforts to achieve individual ideological progress and leap in the struggle more than.
Summed up the work of the past year, that there are many problems and shortcomings. In the future work, only the continuous careful summary, found deficiencies, correct shortcomings, individuals can get faster progress. I think I work well.
An excellent electrical engineer with 15 years of electrical work experience.To seek the position of electrical engineer, in order to give full play to 10 years of state-owned enterprises and five years of foreign engineers work accumulated by the rich professional knowledge and skills, including the design and review of electrical drawings, various industrial field automation control system installation and commissioning, Of the commercial negotiations and on-site installation commissioning and guidance, all kinds of imported equipment maintenance and maintenance.
I hope to be able to use my knowledge and accumulated work experience to better serve your company while maximizing the interests of the enterprise. During the project construction period or after the factory is put into operation, I hope to be an electrical engineer.
University for three years, shaping a healthy, confident I, self-confidence from the strength, but at the same time also realize that the rapid social change, the demand for talent is also growing, society is constantly changing, development, and to With the development of the eyes to see the problem, there are many shortcomings and deficiencies, to adapt to social development, have to constantly improve their understanding of ideas, improve themselves and correct shortcomings. As a it, the social pressure will be more heavy than other industries, to learn to learn, learn to innovate, learn to adapt to social development requirements. Time flies, is a four-year, four-year university campus and social practice of life, is a turning point in my life is a new starting line, a goal, there is the pursuit of success, there are failures and frustrations, the most important point, After this time of tempering, I grew up!
When I was in my freshman year, I listened to the training of my freshman education at school. When I learned that my ability and attitude were the main determinants, I learned, learned, read and accepted new things with my tireless mentality. Concept, active thinking. After four years, familiar with coreldraw, photoshop and other news professional editing software, cooledit, premiere and other audio and video software, in the next three years of school production completed dv drama "and cherish", master basic business ability, "Outstanding third - class students" scholarship, a "second - class scholarship outstanding students" and three "Miyoshi students" honorary title. Arrangement of professional at the same time, I also participated in the work of the school students, two and a half years, really let me benefit. From the initial news network to the subsequent office, I learned how to better team work, learn how to co-ordinate planning, how to organize and coordination, and so on, really pay when there is a sense of responsibility and mission, these gains Is unable to use money, honor and other material to measure the return. Work is both a pressure, but also a driving force in the busy, they will cherish the time to study harder. In organizational life, had the honor to participate in party school learning, through the layers of assessment, join the ranks of the Communist Party of China to prepare, improve their quality, quality, ability and ideological level.
After learning, practice and work life, I still strive to pursue: the completion of the day, Nissin high! Comprehensive evaluation of the students in the department:
The students adhere to the four basic principles, conscientiously study and implement the party's line, principles, policies; politically actively requested progress, submitted to the party organization to join the party application; actively participate in school organization activities; excellent. In business learning, the students work hard, correct attitude, good grades, have a strong time hands-on ability; master a certain basic knowledge and expertise. The students have strict organizational discipline, to comply with the school, department, class rules and regulations, usually strict demands on themselves, subject to management, respect for teachers, unite students, concerned about the collective.
University four years fleeting, look back on the past few years of college life and social practice of life, there are sweet and bitter, laughing and tearful, there are successes and failures. I tirelessly, with super fighting, and constantly challenge themselves and enrich themselves and hope for the future to join the community and lay a solid foundation for the realization of the value of life.
