Maintenance Electrician Technical Summary Report 2
Maintenance Electrician Work Summary I have been working since January 2016. After receiving the third-level education in the factory, I was assigned to the electrical workshop maintenance class and engaged in electrical maintenance work. Strictly demand themselves, humbly ask for advice from masters and colleagues, and be able to combine theory with practice to continuously improve their professional level. They have participated in or independently undertaken installation and renovation projects of electrical equipment for many times, and have been awarded advanced workers by their units for many years. , safety producer and other honors.
In 1992, due to production needs, two new nitrogen and hydrogen compressors were installed in the factory. The electrical part was a 1250kw/6kv synchronous motor. I was honored to participate in the entire process of project installation, from the positioning of wire ducts, From the production of iron parts to the wiring of high and low cables, from the detection and wiring of motors to the installation and debugging of high-voltage switch cabinets, as well as the mechanical debugging of on-site control cabinets, the adjustment of auxiliary switches and the production of high-voltage cable heads, it was the first time I came into contact with kglf-11 I installed and debugged the type excitation cabinet and learned some technical points of synchronous motor installation, which enabled me to make new improvements.
Being non-conformist at work and daring to innovate are the must-have advantages of an excellent maintenance worker. The power supply load of the electrical equipment responsible for my synthetic maintenance team accounts for about 60% of the total load of the entire factory. , there are 15 6kv high-voltage synchronous motors ranging in size from 620kw to 3100kw, plus more than 200 matching asynchronous motors. For a maintenance class with only six or seven people, The daily workload can be imagined, especially in summer, the failure of the synchronous excitation cabinet caused by the increase in ambient temperature often bothers us. During the tedious and repetitive work, I noticed that the transformer in the synchronous machine excitation cabinet was running when , the high temperature emitted is the main reason for the changes in the parameters of the electronic components of the excitation control circuit, causing the system to be out of control and causing equipment failure. Therefore, I proposed the idea of ????modifying the excitation cabinet to the workshop leader, and the rectification was carried out after repeated demonstrations by the leader. The transformers in the original excitation cabinet are separated from the cabinet and placed in a special transformer room for unified heat dissipation. A 38W axial flow fan is used in the control loop to replace the original 800W fan for cooling, which not only reduces the noise, but also optimizes The operating environment has been improved, and the problems that have troubled us for many years have been solved. So far, we have replaced the original electronic plug-in analog control with intelligent module controllers, which has completely solved the problems in the operation of the equipment and stabilized production.
The continuous improvement of business level comes from the process of accumulation of experience in actual work.
From ____ to ____, due to the company's expansion of production, I participated in the installation of the high-voltage part of the 75-ton boiler electrical appliance, the 4.4-meter conversion project, the installation project of the 1200kwa transformer and low-voltage distribution room, and the installation project of the 1.6-meter synthetic 1300kw electric furnace. etc., during the project of installing the synthetic tower electric furnace, through repeated trials, I found out a set of successful experience in assembling the small cover electrode rod of the synthetic tower. I used our pre-made mold to put the small electrode rod cover containing the mica tube into Coat a fine asbestos rope with silica gel (high temperature resistance), press it into shape with a 5-ton jack between the mold and the electrode rod, and then dry it. In this way, the top pressing method replaces the nut twisting method. It ensures the stability during the assembly process of the electrode rod, so that it can withstand the test of 320kg high voltage and other impacts during use, and can withstand the test of 490° high temperature. Our factory has also ended the history of hiring external technicians to solve problems. .
In September ____, due to outstanding work performance, I was transferred to the urea maintenance class as the squad leader. During this period, I organized and installed 6kv/850kv high-voltage motor projects. In ____, our class successively undertook The factory has a new pressure swing adsorption power distribution room, a full set of engineering projects including 1600kva transformers, and the installation and commissioning of a new 620kv/6kv variable speed pump motor. The installation and commissioning of the 90kw air compressor plc of the air compressor station, etc., due to urea The process environment is highly corrosive and the electrical equipment is scattered. In ____, I organized personnel to rectify all the frequency converters in the first and second urine distribution rooms, and set up special frequency converter rooms respectively, which purified the environment, reduced faults, and achieved It eliminates screen detection and centralized control for operators in the main control room, making the original operations simple and clear at a glance, and also facilitates inspection and maintenance by maintenance personnel.
In enterprise production, safety comes first. This is especially significant for our workers in hazardous industries. It is the unshirkable responsibility of a technician to use the technology he has mastered to solve problems existing in production. In the summer of ____, when I was inspecting the urea packaging section, I found that the control switch of the sewing machine under the operator's feet was a 380v power supply voltage, so I came up with the idea of ??changing the original 380v control loop to a 36v safe voltage control. After the transformation, the potential problem was solved potential safety hazards and achieve the purpose of safe production.
More than twenty years of work experience tells me that to be an excellent technician, one must not only have the spirit of hard work, excellence, and continuous progress, but also must be bold, careful, flexible, and innovative. character, I am deeply proud of myself as an excellent technical worker.
Maintenance Electrician Technology Summary Report 3
Maintenance Electrician Technology Summary In the blink of an eye, ____ years have passed. Looking back on this period of dedicated work, I realized the importance of power supply vehicles. The importance and the subjective fact of my lack of business skills made me realize from the bottom of my heart that only by learning professional skills can I ensure the normal and safe use of electricity in production.
I remember that on the day of the apprenticeship examination, there was a sudden power outage in the No. 4 substation of Jingye Station, which caused: 65㎡ zone burning section 1, 7#8# furnace section 2 and the new No. 1 furnace within the jurisdiction of the southern district team. All busbars in Section 1 and Section 2 of the power distribution room were out of power. This power outage not only affected the normal production of a large area, but the most serious one was that a safety accident occurred in the new No. 1 furnace due to the power outage. This accident fully proved the importance of power supply, so as a power supply maintenance worker, I You must have a high sense of responsibility to ensure the normal operation of the power supply system.
Every time I inspected the equipment, I saw how confident each master was, which made me feel that my knowledge was shallow and I felt guilty for not being a good helper to the masters. Therefore, I should strengthen my study, strive to catch up in a short time, and be a good helper to my superiors and masters at work.
In the past few months of work, I have actually found that I still have many problems, such as: low standards of work, lack of responsibility, laziness and other problems that can directly affect my work. Therefore, in future work We must work harder in life and work, correct our shortcomings, and take our work to a new level.

1. Purpose and Significance
Through practical training, students will prepare necessary process knowledge for their future professional experiments and graduation projects. and operational skills, while cultivating students' rigorous work style and good work habits. It is not only an introductory guide to basic skills and process knowledge, but also the beginning of innovative practice and the enlightenment of the innovative spirit.
2. Practical training content
Practical training item 1: Safe use of electricity
(1) The importance of safe use of electricity must be recognized
Safe electricity knowledge is knowledge about how to prevent electricity accidents and ensure the safety of people and equipment. In electronic assembly and welding debugging, you have to use various tools, electronic instruments and other equipment, and you are also exposed to dangerous high voltages. If you do not master the necessary safety knowledge and lack enough vigilance during operation, personal and equipment accidents may occur. Therefore, on the basis of understanding the harm of electric shock to the human body and the causes of electric shock, we must master some knowledge about safe use of electricity to prevent problems before they occur.
(2) Electric shock and related protective measures
1. Types of electric shock: (1) Electric injury. Electric injury usually includes three types: burns, electrocautery injuries, and skin metallization. . The harm caused by electrical injuries to the human body is generally non-fatal. (2) Electric shock refers to an electric shock accident in which electric current flows through the human body, seriously affecting the human body's breathing, heart and nervous system, causing muscle spasm, nerve disorder, respiratory arrest, and seriously endangering life. Electrocution is mostly caused by electric shock. It is the current flowing through the body, not the voltage, that determines the intensity of the shock.
2. Factors that affect the degree of human injury caused by electric shock: current size, current type, current action time, current path, and human body resistance. The body's electrical resistance changes with the dryness of the body's skin and the age of the person. When it is dry, it can show more than 100,000 ohms. When it is wet, the resistance can drop below 1,000 ohms, and it becomes larger as people age.
3. Causes of electric shock: direct electric shock, indirect electric shock, electrostatic shock, and electric shock caused by step voltage. 4. Technical measures to prevent electric shock: (1) Protective grounding and protective zero connection (2) Electric shock protection device
Another important point is what should be done if you really see someone else getting an electric shock. measures. First make sure to disconnect the power supply or use an insulator to move the wire away from the person who gets the electric shock. If the person who gets the electric shock stops breathing but has a heartbeat, artificial respiration or external chest heart compression should be performed.

3. Training summary or experience
In the first week, I conducted practical training as an electronic electrician. The master taught us the relevant knowledge about safe use of electricity. This is relevant to us. It is related to our daily life, and it allows us to have a better understanding of how to use electricity safely on the original basis. Through the master's explanation, I learned the basic knowledge of safe use of electricity and understood the importance of safe use of electricity. And this lays the foundation for electrical and electronic training and safe electricity use in future study, work, and life. During the one-week electronic and electrician training, the master also gave us a general description of the future training plan and explained some requirements and precautions. This also made me full of expectations and curiosity about future training.
In the second week we assembled the lighting circuit. After listening to the master's introduction to the content of our class, we started to do it. We worked in teams of two and connected the lines ourselves, then turned on the circuit and turned on the lights. I was very happy to see the lamp I assembled turned on. When the master came over to sign, he probably thought we were like children, sharing our joy and signing for us with a smile. This time our group went very smoothly. Although we encountered some minor difficulties during the process, with the master's patience and careful explanation, we were able to make timely corrections without any hindrance. The master could always point out our problems to the point and provide us with solutions. Guide us in the right direction and at the same time teach us how to figure out where we are going wrong. During this practical operation, I had an initial personal experience of what it was like to be an electronic electrician. Through this assembly, we learned what incandescent lamps and fluorescent lamps are and the basic components of incandescent and fluorescent lamp lighting circuits.
In the third week we carried out the project of using commonly used electronic instruments. After the master's explanation, we learned about the functions of DC stabilized power supplies, multimeters, signal generators, oscilloscopes and other common electronic instruments before starting the operation. I used an oscilloscope to measure the calibration signal square wave and got the following data: the peak value is 0.44V, the period is 10.4mA, and the frequency is 0.096Hz; the measured peak-to-peak value of the 1.5KHz, 10dB sine wave is 5.5V, then the peak value is 2.75V, the period is 17mA, then the frequency is calculated from the period, and the difference with the displayed frequency is small. Through this class, I mastered the basic usage methods of DC stabilized power supply, multimeter, signal generator, and oscilloscope, which also laid the foundation for my subsequent practical training. f is 2.75Hz
In the fourth week of practical training, we conducted understanding and testing of commonly used electronic components. At the beginning, through the master's explanation, we briefly understood the functions of resistors, potentiometers, capacitors, inductors, diodes, transistors, integrated circuit chips and other components as well as some other knowledge related to them. During the training process, I learned about various commonly used electronic components through physical objects and mastered the reading methods of commonly used electronic component parameters and the method of using a multimeter to measure the parameters of commonly used electronic components.
In the color ring resistance reading, I read a four-ring resistor whose color ring is orange, black, red, and silver. The resistance value is 30__100±5 and the resistance value measured with a multimeter is 2.9 kiloohms. Then it can be compared. It is almost the same, which proves that the previous reading is correct; then use a multimeter to measure the maximum resistance of the potentiometer to be 0.01 milliohms; use a multimeter and a multi-purpose adapter plug to measure the capacitance of the capacitor to be 0.01 milliohms, and I In this lesson, we learned the difference between diode and triode pins. After completing the above steps, we prepared a diode experimental circuit. After I connected the circuit and turned on the power, the diode lit up, so the circuit connection was successful. Through this simple experiment, I learned about the functions of commonly used electronic components and deepened my understanding of circuit connections. In the second class, we started our welding process and welding training based on the first class. Also under the detailed and careful explanation of the master. After we became familiar with the basic knowledge and requirements of the electronic assembly and welding process, we began to operate. What we are going to do is a soldering exercise on a printed circuit board. We soldered the components on the universal circuit board according to the circuit diagram. I just started soldering the first component, which was a diode. The soldering iron and tin in my hand kept shaking uncontrollably. I kept telling myself to be steady. But my hands were still shaking, maybe it was the first time I was nervous and it was unavoidable. My first welding attempt ended with my hands shaking. But maybe because I really understand what welding is all about, and I feel confident about it, I can weld much better the second time, my hands don’t shake much anymore, and the more I weld, the more familiar I become. After gaining experience, I became very good at welding. When the morning time came, none of my colleagues had finished welding, and neither did I. The master said to go back first and continue in the afternoon.
In the fifth week, we continued welding technology and welding training. At the same time, the teacher also talked about the production of AS-06FM radio. Colleagues who completed the previous project can continue to work on this project. We all arrived early in the afternoon. As soon as we arrived, we sat down and continued the morning welding. Without the fear and nervousness in the morning, I started to use it as soon as I picked up the soldering iron. Not to mention that it was really good. At this time, after these days of practical training, we all have the attitude of electricians. When we arrived, we saw that there were colleagues who arrived earlier than us who were welding and felt as if we had entered an electrical factory. This was different from the feeling at the beginning. Not the same. The class didn't take long.
I was still welding hard and seriously, and one of my colleagues succeeded. Although I was a little slower than other colleagues, I was still very stable. I thought I couldn't make mistakes because I didn't get it right at the end, so I welded slowly and carefully bit by bit. After almost an afternoon of hard work, I finally welded the astable multivibrator circuit. The most critical moment arrived, because then I had to use the DC stabilized power supply that I had learned to use before to conduct a power-on test. With tension and expectation, I connected the circuit and pressed the output button. At this time, I saw two light-emitting diodes taking turns to light up, flashing and flashing. I thought it was really beautiful. My mood at this time was really It can be described as elated. That feeling of being rewarded for your hard work is really good. This practical training content takes more time and yields more results than the previous content. I feel that after this welding, I am no longer afraid of anything you ask me to weld. Moreover, I have a preliminary understanding of the electronic assembly and welding process and common welding and assembly tools. I have mastered the correct use of welding tools and common tools as well as manual electronic welding technology, which laid the foundation for future training product installation of radio preparation. .
The sixth week of electronic and electrician training is also the last week of practical training. The content of our training today is the production and circuit debugging of printed circuit boards (PCB). Under the master's explanation, we understood the basic process of making PCB board circuit diagrams. According to the process described by the master, we completed the task smoothly and successfully. , so that I became familiar with the basic operations of making PCB boards and mastered the operation of using thermal transfer to make PCB boards.
In the end, this time it ended with me feeling nostalgic. With the careful guidance of the master, the active help of my colleagues and my serious efforts, the practical training ended successfully. Get into the job!
