2014 electrical technician work summary

Electrical technician work summary

Time flies, and it has been a year since I arrived in the company. I feel a lot and I have gained a lot. Entering ** City ** Electrical Equipment Co., Ltd. is a good development opportunity for me, and also a good opportunity to exercise and improve my ability in all aspects. Here, first of all, I would like to thank the company leaders and colleagues for their great support, care and help, so that I can quickly adapt to the company's management system and work hard to do my job. Since entering the company, I have carefully understood the company's development profile, learned the company's rules and regulations, and are familiar with the company's process. At the same time, I have truly felt the positive and inspiring corporate culture, which has benefited me a lot. I will summarize my work in the past year as follows:

First, work hard

I entered the ** from the sheet metal workshop, to do the box cabinet shell, it can be said that the sheet metal workshop is my first impression of the company. I have to say that in the month of the sheet metal workshop, the masters have given me a good image and benefited me a lot.

In September last year, I entered the assembly workshop for an internship. I deeply felt the spirit of my colleagues' dedication and perfection. In the assembly workshop, my focus is to understand the operation and principle of each electrical equipment by consulting relevant materials, manuals, drawings and manuals, learning equipment layout, wiring, making rows, secondary lines, etc. When I entered the assembly workshop, I knew that my burden was very heavy. I always remember this sentence: "To give someone a bowl of water, you have a bucket of water." Because I know that it is not an easy task to become a qualified technician. As a technician, not only can we deal with the requirements put forward by customers, but more importantly, it can solve the problems on the spot and run the machines on site. The situation needs to be counted.

In May of this year, following the company installation team to Panzhihua, I took the time to familiarize with the drawings, construction plans, drawing review, on-site construction management, completion acceptance and other requirements. In the face of difficulties and problems, actively ask the leaders, communicate with the design units and construction units, and coordinate various relationships so that the project can smoothly carry out the work. In actual work, due to some local civil engineering changes and drawings, the wall surface has no holes, the bridge and the pipe are not connected, and it is necessary to open the hole or re-arrange the route to increase the workload. Now the communication with the leader has been solved. Therefore, in the future work, I will pay attention to relevant knowledge, strengthen myself from the aspects of civil construction, decoration, budget, etc., do a good job of external coordination, actively communicate with the design unit, the construction unit and the government, and formulate a good overall plan. All are based on the interests of the company.

Second, study hard and keep improving

At work, study hard, constantly improve yourself, and use other time to learn new and new knowledge. From the simplest manufacturing specifications to the complete set of equipment, here is both hardworking and eager to learn, and it is inseparable from the answers and doubts of the workshop colleagues. I have learned a lot from old engineers and gave me a lot of insights. For the equipment I made for the first time, my colleagues not only carefully helped me to review and patiently explained to me, but also thanked my colleagues for their help, and also had sufficient confidence in the better work in a cultural atmosphere like our company.

Third, defects and shortcomings

Because I have been working very late, I have not enough skills and experience in many aspects. I have encountered many problems and I can't handle the problems well. In the future work, we must dare to solve and deal with problems, encounter problems, never evade, humbly learn from experienced technicians and old workers; in addition, organize lessons in a timely manner, and record existing doubts and unintelligible aspects. Go down, and take the time to solve the problem, make a record, so that you can encounter the same thing in the future, and you can solve it faster. Seriously study all kinds of knowledge so that in the future work, you can better complete the tasks and tasks of leadership arrangement and make yourself mature faster.

Fourth, self-evaluation

Although I spent only one year in production labor and technology learning, I have greatly improved and improved both in terms of thinking and technology. It not only enriches knowledge, but also improves its management and business level. The most important thing is to lay a good foundation for better accomplishing tasks in the future work.

Summarizing the work of the past year, there are both achievements and deficiencies. In the future work, only by constantly summing up seriously, discovering deficiencies, and making efforts to correct, can we get faster progress, and better serve the company and realize the value of life.

Electrical technician work summary

Time is always in a hurry, how long is one year? Three hundred and sixty-five sunrises, three hundred and sixty-five sunsets, XX years have passed in the alternation of sunrise and sunset, looking back at the work of the year And life is full and half of each.

This year I am still responsible for electrical work in the overall renovation project of Beidaihe Sanatorium. In the first half of the year, it was mainly structural construction. The electrical aspects cooperated with the civil works to do pipeline pre-burial and grounding lightning protection. The construction team of the electric project is the local construction company of Qinhuangdao. The quality difference between the construction quality and the construction team in Beijing is not one-and-a-half-point. The requirements of the department are too low, so my other identity in the first half of the year was a professional quality inspector. They also provided them with a learning opportunity while strictly demanding them. Of course, there must be sufficient reasons to convince others. There should be solid professional knowledge.

The situation of this project is special, close to the sea, the ground is a hard rock, and thus encountered two situations. First, the corrosion of the seaside is particularly heavy. The original design uses all the galvanized steel pipes and welded steel pipes. These two types of tubes are the most durable, but they are not suitable for use at the seaside. Whether it is a galvanized tube or a welded steel tube, it is exposed to the air for half a month. It is a thin layer of rust layer. Peeled off. The brushed anti-rust paint has long since lost its effect. When the project was reviewed, the supervisor gave me this point and was dubious at first. In the case of design approval, only the upper part of the strong electric ground was changed to pvc pipe, and the galvanized steel pipe used in the concrete pipe was used. After one and a half months of summer shutdown, the surface of the structural column and the steel pipe reserved on the site were all thick and thick. I was shocked and secretly hijacked: I really don’t listen to the old man’s words and losses, and the experience is really useful! Second, because the foundation is full of rocks, the lightning protection effect is not good, the original design of lightning protection grounding method If the value is less than the standard requirements, it can only be used as a grounding electrode or a drag reducing agent when it is not connected to other building foundations.

Beidaihe was suspended for one and a half months due to the summer project. We also went to Shanghai for the renovation project. Shanghai is a bustling city. It is the latest fashion in the city. Her architecture also has its own unique style. In Shanghai, we have seen the Bund buildings known as the “World Architecture Exhibition” and have seen the former “War East Wall Street”. "The wind." Bank of China, Peace Hotel, Customs House, HSBC... These buildings are not from the same designer, nor are they built in the same period. However, their architectural tones are basically unified, and the overall contour processing is amazingly coordinated. Whether it is far-sighted or in the meantime, you can feel a strong, powerful and graceful momentum. This short trip made me realize that my eyes are narrow, the knowledge is lacking, and the individual is small. Is Jinmao Tower and Oriental Pearl really out of reach?

In the second half of the year, my work was mainly responsible for the electrical piping laying and power supply and distribution schemes of the guest rooms. The laying of electrical pipelines should be very simple, but because the plan is not perfect, the role of the drawings is constantly changing, and the work is not working. But fortunately, it is a test for yourself, and more opportunities to grow.

Originally thought that the power supply plan would run very well, the fact once again taught me a lesson: the light enemy must be beaten. Shanghai's design plan can not be used in the Beidaihe area, there is no way to start from scratch, knowledge is learned in repeated setbacks.

After XX years of work and life, more and more contact with 80 or 80, I saw that they were all in their respective fields, ambitious, and the inner panic was born.

Come on, time can't be lost again.

Electrical technician work summary

My name is *** and I have been working in electrical equipment maintenance for 5 years. I have been working in the company since ***, and I have been working for more than two years. Since entering the company, he has been engaged in substation operation maintenance and management. Participated in and organized the setting and inspection of high voltage measurement and relay protection; reactive power compensation and voltage setting; DC screen inspection and maintenance; substation secondary line failure and treatment; high voltage cabinet failure and treatment; high voltage cable head Production and processing; overhaul and maintenance of the substation in spring and autumn; fault handling and maintenance of outdoor high-voltage overhead lines. I always combine the hard research technology with the high-pressure technology operation rate, actively learn the principles of various high-voltage equipment and their maintenance experience, and continue to improve my theoretical and practical skills, and solve many problems encountered in the substation operation. Technical difficulties have laid a good foundation for improving the operating rate of power receiving and transmission equipment.

A substation is a place in a power system that transforms, concentrates, and distributes the voltage and current of electrical energy. In order to ensure the quality of electrical energy and the safety of equipment, voltage regulation, power flow control, and protection of transmission and distribution lines and major electrical equipment are also required in the substation. The work that has been experienced in the substation for two years is summarized as follows:

1. Types and treatment of faults that occur in daily operation of vacuum circuit breakers.

On November 8, 2019, due to the line failure of the power company, the company's large network power was cut off for 3 hours. After receiving the notice, we will make a power outage for each power line according to the regular power outage procedure of the substation. After the power company handles the faulty power transmission, it sends power according to the power transmission step. At this time, it was found that the 35KV No. 1 main transformer vacuum circuit breaker refused to be closed. This is the first time that the company has just started production in the two-month substation. The vacuum circuit breaker used in the 35KV high voltage cabinet of our substation is Chint. ZN85-40.5 circuit breaker. In the experimental state, after the circuit breaker is closed, the closing electromagnet will act, the iron core rod will open the closing scorpion, the closing spring will release the energy, and the circuit breaker will be closed, but the circuit breaker arc extinguishing chamber cannot be combined. brake. After analysis, it shows that the mechanical fault has been eliminated, indicating that the secondary line is faulty. During the inspection, it was found that the secondary auxiliary plug had a needle and the control line were unwelded. After the treatment, the vacuum circuit breaker was closed and the fault was solved. In the daily work, the most common faults of the vacuum circuit breaker are summarized: 1. The positive air circuit breaker refuses to open the brake

2. After the vacuum circuit breaker mechanism stores energy, the energy storage motor does not stop. 3. The vacuum circuit breaker arc extinguishing chamber cannot be disconnected. 2. The current transformer is opened twice and processed.

At the end of the year*, the power company sent a breakdown of the electricity bill in February, which was 20182KW.h from the electricity metered by our company. I led the technicians to conduct a comprehensive inspection of the high-pressure metering. Due to limited conditions, the problem was not found. The company invited the power company's metrological verification center to conduct secondary line verification tests at the substation. For 35KV and 10KV switchgear current transformers, voltage transformers, secondary voltage drop and secondary load, electric energy meter test. In the test of the power company's instrument, it was found that the 35KV high backup protection terminal has an indirect open circuit. After processing, compared with the power company measurement center in the specified time, the problem has been solved. The current transformer, that is, the number of turns of the CT primary winding is small. When the primary winding is used in series, the secondary winding is connected in series. The number of secondary windings is large, and it is used in series with the current coils such as measuring instruments and relays. The current coils of measuring instruments and relays are very small. Therefore, the CT is close to the short-circuit state during normal operation. The magnitude of the CT secondary current is determined by the primary current, and the magnetic potential generated by the secondary current is the magnetic potential that balances the primary current. If the secondary open circuit, its impedance is infinite, the secondary current is equal to zero, and its magnetic potential is equal to zero, it can not balance the magnetic potential generated by the primary current, then the primary current will all act on the excitation, causing the iron core to be severely saturated. Magnetic saturation increases the iron loss, CT heats up, and the insulation of the CT coil is burnt out due to overheating. Residual magnetism is also generated on the core to increase the transformer error. The most serious is that due to magnetic saturation, the sinusoidal wave of the alternating magnetic flux becomes a trapezoidal wave. At the moment when the magnetic flux changes rapidly, a high voltage is induced on the secondary coil, and its peak value can reach several thousand volts, so high. The voltage acts on the secondary coil and the secondary circuit, posing a serious threat to both the person and the device.

3. Complete the leadership and assign other basic and temporary work.

Over the past year, I have grown and matured in my studies and work, but I know that I still have many shortcomings, such as lack of work ability and innovation consciousness, and the need to improve the political theory. In the future, I will try my best to do the following: I hope that leaders and comrades will supervise and guide me:

1. Consciously strengthen learning, learn from theory, learn from professional knowledge, learn from colleagues around you, and gradually improve your theoretical level and business ability.

2, to overcome the young and discouraged, to be down-to-earth, to improve work initiative, not afraid to do more things, not afraid to do small things, improve themselves in the practice of bit by bit.

3. Continue to improve their political self-cultivation, strengthen the sense of purpose of serving the people, and strive to become an outstanding national civil servant.
