Summary of electrical engineering

Since I started my work, I have been working as a maintenance electrician in the unit. Over the years, I have strictly demanded myself, conscientiously, and studied electrician technology, making a certain contribution to the safety of the unit. Now summarize it from the following aspects:

I. Political and ideological aspects: Conscientiously participate in various ideological and political studies and business technology training organized by the unit, consciously obey the unit's unified management and obey the distribution. Unite colleagues and respect leadership.

Second, safety production:

1. Seriously study and implement the spirit of the superior file, improve the awareness of safe use of electricity, and enhance the sense of responsibility.

2. Implement and improve the safety power organization system, improve the safety management rules and regulations, and operate in strict accordance with the rules and regulations.

3. Strengthen the safety management of the team's electricity consumption and consolidate the safety foundation

4. Keep in mind that a person who uses electricity must ensure his own safety and the safety of others.

Third, training and learning: For many years, I actively participated in various learning and training, and strive to learn basic knowledge of electrician knowledge, power supply system knowledge, line devices, lighting devices, grounding devices, transformer operation and maintenance, motor repair and maintenance, machine tools Electrical control circuit, PLC control and other related knowledge systems. Every time I study, I have learned some new theories and used them to guide my work practice and apply them to my work. I have improved the power supply system and control system of the factory and received consistent praise.

Fourth, the practical application: I actively use the knowledge I have learned, and made a great contribution to the unit's energy saving. For example, for the unit night lighting circuit transformation and automatic control, the unit saves nearly 1,000 kilowatt hours of electricity every year. At the same time, the old equipment of the factory was electrically transformed to rejuvenate some old equipment.

V. Practice production: In the production practice, because the unit is equipped with more motors, I have studied hard to find and eliminate the electrical faults of the motor. For the various types of fault repair of the motor, the following experience is summarized:

1. Check whether the insulation of the lead wire is intact, whether the motor is overheated, check whether the wiring meets the requirements of the nameplate, and whether the winding and the first and last ends are correct;

2. Measure the insulation resistance and DC resistance to check whether the insulation is damaged. Whether there are open circuit, short circuit and grounding in the winding;

3. Power-on inspection When a problem is found at the end of the above-mentioned inspection, the power can be directly tested, and a three-phase voltage regulator is used to start applying a lower voltage, and then gradually rise to the rated voltage. Use the above inspection method to find faults for multiple motors in the factory and fix them. Timely summary of various fault phenomena and solutions, and documented, used to guide practice, but also improve their business level.

In short, in the production practice to achieve the rules and regulations on the wall, in strict accordance with the rules and regulations. Over the years, my unit has not had a life safety failure caused by electricity, and has made great contributions to the technical transformation of the unit and the more scientific and rational operation of the equipment.

Summary of electrical engineering

After two years of work, I have accumulated a wealth of work experience. Our maintenance industry is full of competition. Only a better service attitude and better technical level can lead in the industry, but these must start from each employee. In our work, while improving our personal skills, we should have a people-oriented awareness, think of things in front of others, and do things in front of others, so that we can seize the opportunities in the competition.

During the overhaul, the workshop made a comprehensive approach to safety protection, which made me feel a great sense of safety during the overhaul. In terms of technology, our electrical area also organized many trainings and learnings. Every time there is an uncommon fault in the equipment, The organization will discuss and analyze, so as to improve the level of personal skills, to ensure that in the event of similar failures, it can be quickly and very well, to deal with the faults, to ensure full production and better work.

In the past two years, as long as I encounter problems that I don’t understand at work, I will check the information in time and ask questions from the technical staff of Party A, plus I will seize every opportunity to exercise myself and put the book above. Knowledge is applied to the actual operation and masters certain operational skills. Such as; overhaul of the big bag slewing system, overhaul of the car, the replacement of the electric slip ring of the big bag, the maintenance of the weighing of the large and medium bag, the replacement of the crystallizer vibration system and routine maintenance, the maintenance of the segment drive system, the inverter Daily maintenance and parameter setting, maintenance and off-line repair of three-phase asynchronous motor, maintenance and replacement of flame cutting machine, calibration of pneumatic control valve, external wiring and maintenance of PLC, etc., we must be careful during maintenance, such as us In the process of repairing the encoder, be careful when tightening the terminal. It is necessary to control the strength of the tight wire. Because the wiring of the encoder is 0.7 square millimeters, it is particularly thin. If the force is too large, it will hurt the wire cortex. It seems that it is not A big and important detail, if the motor runs continuously for a long time, it should be affected by the vibration of the motor. The slow wire may break. If the encoder of several important parts of our casting machine fails, it may bring the equipment. Great damage, so we must be responsible for the equipment during the inspection, responsible for themselves, must be careful when overhauling.

As an overhaulian, I feel that we must keep in mind three points during the overhaul.

1. Implement the spirit of the company's superior files, improve self-use awareness, and enhance self-responsibility. Do three things without hurting, that is, not hurting yourself, not hurting others, and not being hurt by others. The safety disclosure must be put in place. There must be more than two people in the maintenance work. The power is shut down and the three parties must confirm that they must be in place.

Since I served three electric class monitors in the past month, I have not had a safety accident in my class during these eight months. Our class strictly enforces the three-shift operation management regulations. The skill level of our class is in daily maintenance and many times. During the training, it has been greatly improved, so that our staff can be eliminated in the shortest time when the equipment fails.

In the year, our continuous casting machine has repeatedly affected production accidents due to electric instruments. On the evening of October 13, the 8# machine was repaired. When the 11-segment external arc contactor was replaced, it was not carefully confirmed after the completion of the work, resulting in 220v. Strings such as 24v modules, the main module plc part of the module burned, although this accident is not caused by our class, but this accident is a typical example, reflecting that we still have great defects during the overhaul, the construction workers have no responsibility during maintenance There was no confirmation from the three parties. Our team conducted a whole class study on the accident to improve the responsibility of the staff of my team. I fully requested that my class members be responsible for the equipment during the inspection and be responsible for their work, so as not to be careless. Cause unnecessary losses to ensure the normal and orderly operation of the work.

Although in my two years of work, I have taken a big step towards my goal, I still see that I still have a lot of deficiencies, lack of theoretical level, sometimes too sloppy thinking, and not enough thinking. It is the direction that I need to work hard in the new year. In XX years, I will learn from the lessons of XX years and do my job better. Make our equipment more stable. I will summarize some of the uncommon faults that occurred in XX and organize the whole class to learn. In order to improve the overall maintenance capacity of the team, comprehensive safety accidents occurred in XX years, study, and strive for a better job in the new year.

Summary of electrical engineering

At the end of the year, the new year is approaching, and unconsciously, the XX year has passed. In the past year, under the correct leadership and care of the leader of the station, under the leadership of the value, with the help of the members of each team, I have become a positive person in the current operation from the beginning of a newcomer who participated in the work of substation operation. On duty, and closely around the company's central tasks, adhere to the "safety first, prevention-oriented" policy, work hard, achieve better results in all aspects, and comprehensively and high-quality completion of the tasks assigned by superiors.

Looking back over the past year, I have mainly done the following aspects:

1. Safety production is the top priority of all work. During the year, I strengthened the study of the "Electricity Safety Work Regulations"; timely study safety briefings, supervision reports and accident reports, and learn the lessons of accidents; "Three tickets", standard operation, put an end to habitual violations, and consolidate the basis of safe production. In the power-off process of this year's various switch-off operations, especially the comprehensive maintenance, I was able to strictly follow the normalization process of the switch-off operation and successfully completed the switch-off operation this year.

I also actively participate in daily security activities and various topical security activities deployed by superiors. Through the participation of daily safety activities, we carefully study the guidelines and policies for safety production, the instructions and requirements of the higher authorities, carefully study the safety briefings and accident notifications issued by the higher authorities, and carefully study the relevant procedures and systems. I have found many jobs. The lack of security and security awareness has also been greatly improved. In addition, according to the seasonal characteristics and the requirements of the superiors, I also actively participated in the spring safety inspection, the autumn safety inspection and the “safety month” activities. According to the deployment and requirements of the superiors, I will carefully study and seek with the work attitude of seeking truth from facts, and find colleagues. Weaknesses and equipment defects in safe production. 2. Excellent business skills are the premise of safe production, so I also actively carry out my own business skills training while at the same time. Through more than a year of accumulation of study and work experience, although there has been a certain improvement in the business level. However, at present, with the continuous updating of our equipment, we must strengthen the training of job skills. To this end, it is necessary to strengthen their own business learning, study the technical level, improve their business skills and emergency response capabilities, and make monthly technical questions and answers, on-site examinations and accident predictions, and quarterly anti-accident exercises. Actively participate in the substation maintenance test work, ask the master of the on-site debugging and maintenance, and combine the knowledge on the books with the specific equipment to learn.

3. While completing his own work, he also actively participated in the work of the team.

This year our team set up the qc team at the beginning of the year, and I was responsible for the production of qc in the group. The subject of our qc group was released at the station in November, and the results were unanimously recognized by the station leaders. This qc activity has made my work ability and ability to solve problems have been well trained.
