Technical summary report of maintenance electrician 1

20____ is also my second year working in the engineering department of _ _ _ _ Property Co., Ltd. During this year, I was able to abide by the law, study hard, study hard, be conscientious and diligent, and played my due role and made contributions in the operation and maintenance post, which is summarized as follows:

A, dedication, solid work, to assist the leadership to complete the receiving work.

This year, according to the company's work arrangement, I was transferred from _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ During the receiving period, carry out the instructions of the leader, carefully check the handover project in charge, report the abnormal, damaged and faulty equipment as soon as possible, require the original unit property to be handled in time, and assist the leader to do the receiving work well.

Second, be familiar with the geographical location and equipment of computer rooms and electrical rooms in various regions.

When I first came to the news center, I was completely unfamiliar with the environment and equipment here, and the original Baihua Property didn't cooperate, so I relied on my past experience to explore, think and sum up a lot of things, and added _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

Third, do a good job in the operation and maintenance of central air conditioning and high and low voltage circuit systems.

For central air-conditioning, the central air-conditioning should be reasonably controlled according to the customer's demand, season and weather, and the operation records should be kept. All parameters should be carefully looked at. If any abnormality is found, the reasons should be analyzed and reported, and the maintenance unit should be informed to deal with it quickly. In terms of maintenance, the original property company did not do any maintenance work on the original central air-conditioning system, which led to rust damage on the inner wall of the refrigeration system. According to the arrangement of the leader, the requirements of the leader are strictly implemented, the maintenance supervision of the external unit is strengthened, and the special supervision of the dispatcher is followed up. It is required to clean regularly every week and add medicine regularly every month. Any place that is not in place for maintenance is required to be dealt with immediately to prevent the maintenance personnel of the external unit from being careless and causing further damage to the cooling system, and to ensure the normal operation of the air conditioning host.

On the other hand, under the formulation of director _ _ _ _ _, the surfaces of the machine room floor, air conditioning host, cooling pump and freezing pump are cleaned every month according to the schedule, and the bearings of the cooling pump and freezing pump are regularly maintained with snow oil. For high and low voltage systems, the maintenance work of high-voltage maintenance units has been strengthened, requiring inspection twice a week, and problems found should be handled in time. When the low voltage side just took over, the contactor line of No.2 capacitor compensation cabinet in the public power room was loose, which caused the phase line to touch the cabinet shell and burned the contactor to ground. According to the arrangement of the leaders, all the contacts in the capacitor compensation cabinets of all power rooms were comprehensively reinforced, and defective capacitors were replaced, so that the public power rooms were strictly implemented. And cleaning the electric wells on all floors, strengthening the contacts, replacing the damaged indicator lights, etc. , and regularly clean the floors of all electrical rooms to ensure that the equipment runs in a good environment.

Fourth, conduct central air conditioning training for operation and maintenance team members.

Under the arrangement and support of the leader, I gave a brief explanation to the staff of the operation and maintenance group about the central air conditioning. Some employees who are unfamiliar with air conditioning or have never been exposed to air conditioning have received little effect, their expression ability and self-confidence have been greatly improved, and their understanding of air conditioning has been further strengthened. Thank you _ _ _ _ _ _ _ and other leaders for their trust and support.

Five, do a good job in the management of class members, and do a good job in the task of calling for repairs by superiors and news organizations.

I set an example by asking my class members to abide by the company's laws and regulations, not to be late or leave early, to strengthen the responsibility training of class members, and to make good records of equipment inspection and operation. Arrange work reasonably according to the schedule of superiors, mobilize class members and deal with them quickly. Listen carefully to the call from the news center, and record the calling unit, call content and fault location. , quickly mobilize the whole class to deal with it quickly, and carefully explain and report the major failures or problems that cannot be handled to customers.

The above is mainly the main work in the past year, which is gratifying and needs to be improved. I am glad that I have been the head of the team here, and I have little management experience. Moreover, I learned a lot of knowledge and skills in the process of receiving, and what I need to improve is management level, interpersonal relationship handling and technical skills, so I will definitely work harder to get to a higher level next year.

Summary report of maintenance electrician technology II

Summary of maintenance electrician's work: he started working in January and was assigned to the maintenance class of electrical workshop after three-level education in the factory. I am strict with myself in my work, and humbly ask my master and colleagues. I can improve my professional level by combining theory with practice. Participated in or independently undertaken electrical equipment installation and renovation projects for many times, and was awarded the honor of advanced worker and safety producer by the unit for many years.

1992 due to production needs, the factory newly installed two nitrogen and hydrogen compressors, and the electrical part was 1250kw/6kv synchronous motor. I had the honor to participate in the whole process of project installation, from the positioning of trunking, the manufacture 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 switchgear, as well as the mechanical debugging of on-site control cabinets, the adjustment of auxiliary switches and the manufacture of high-voltage cable heads. For the first time, I contacted the installation and debugging of kglf- 1 1 excitation cabinet, from which I learned some technical points of synchronous motor installation and improved myself.

Being unconventional in work and daring to innovate are the advantages that an excellent maintenance worker must have. The power supply load of electrical equipment in my synthetic maintenance class accounts for about 60% of the total load of the whole plant. Only 6kv high-voltage synchronous motors have 620kw to 3 100kw/0/5 motors, plus more than 200 asynchronous motors matched with them. For a maintenance class with only six or seven people, the daily workload can be imagined, especially in summer, the synchronous excitation cabinet failure caused by the rising ambient temperature often bothers us. In the tedious and repetitive work, I noticed that the high temperature emitted by the transformer in the excitation cabinet of synchronous machine is the main reason for the system out of control and equipment failure caused by the parameter change of electronic components in the excitation control loop. Therefore, I put forward the idea of transforming the excitation cabinet to the workshop leaders. After repeated argumentation by leaders, the transformer in the original excitation cabinet was separated from the cabinet and put in a special transformer room for unified heat dissipation. In the control loop, the 38w axial fan is used to replace the original 800w fan for heat dissipation, which not only reduces the noise, but also optimizes the operating environment. So the problem that puzzled us for many years was solved. So far, we have replaced the original electronic equipment with intelligent module controller.

The continuous improvement of business level comes from the process of experience accumulation in practical work. Due to the expansion of production, from _ _ _ _ to _ _ _ _ _, I participated in the installation of high-voltage part of 75-ton boiler electrical appliances, 4.4m conversion project, 1200 kw transformer and low-voltage distribution room installation project,1.6m synthesis project 1300kw electric furnace installation project, etc. After repeated experiments, I found that the electrode rod cover with mica tube was placed in our pre-made mold, wrapped with fine asbestos rope and coated with silica gel (high temperature resistance). Press it between the mold and the electrode rod with a 5-ton jack at one time, and then dry it. In this way, the jacking method replaces the nut tightening method. The stability of the electrode rod in the assembly process is ensured, so that it can not only withstand the impact of 320 kg high pressure, but also withstand the test of 490 high temperature. Our factory has since ended the history of hiring foreign technicians to solve problems.

In September of _ _ _, due to my outstanding work performance, I was transferred to the urea maintenance class as the monitor. During this period, I organized the installation of a 6kv/850kv high-voltage motor project. In, our class successively undertook the newly-built upper pressure swing adsorption distribution room in the factory, including 1600kva transformer, installation and debugging of newly-built 620kv/6kv displacement pump motor, etc. Plc installation and debugging of 90kw air compressor in air compressor station. Due to the corrosive environment of urea process and scattered electrical equipment, in _ _ _ _ _ _ _, I organized personnel to rectify all inverters in the power distribution room of urea I and urea II, and set up special inverter rooms respectively, which purified the environment, reduced failures, realized the screen detection and centralized control of the operators in the general control room, made the original operation simple and clear at a glance, and also facilitated the maintenance and maintenance of maintenance personnel.

Enterprise production safety first. This is especially important for employees engaged in dangerous industries. It is the unshirkable responsibility of a technician to use the mastered technology to solve the problems existing in production. In the summer of _ _ _ _, I found that the control switch of the sewing machine under the operator's feet was 380v power supply voltage, so the idea of changing the original 380v control loop to 36v safe voltage control came into being. After the transformation, the potential safety hazard was solved and the purpose of safe production was achieved.

More than 20 years' work experience tells me that to be an excellent technician, we should not only have the spirit of hard work and continuous progress, but also have the character of boldness, prudence, flexibility and innovation. As an excellent skilled worker, I am deeply proud.

Technical summary report of maintenance electrician 3

In a blink of an eye, _ _ _ years have passed. Looking back on my time in professional work, I realized the importance of the power supply car and the subjective fact that I lacked professional skills, and realized from 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 exam, the 4# transformer in the special station suddenly went out of power, which led to the failure of all the buses in the 65m2 belt burning section 1, 7#8# boiler section 2 and 1 section 2 of the newly-built 1# boiler distribution room. The power outage accident did not affect normal production in a large area. The most serious thing is that the new 1# boiler has a safety accident due to power failure. The accident fully proved the importance of power supply, so as a power supply maintenance personnel, we should have a high sense of responsibility to ensure the normal operation of the power supply system.

Every time I overhaul the equipment, I see that every master has an answer, which makes me feel that I have little knowledge and feel guilty that I am not a good helper of the master. So I will study harder, try to catch up in a short time, and be a good helper for my superiors and teachers in my work.

In these months' work, I actually found myself with many problems, such as poor work standard, weak sense of responsibility and laziness, which can directly affect my work. Therefore, I will work harder in my future work and life, get rid of my shortcomings and let my work go to a new level.

I. Purpose and significance

Through practical training, students can prepare necessary technical knowledge and operational skills for their future professional experiments and graduation projects, and at the same time cultivate their rigorous work style and good work habits. It is not only the introductory guidance of basic skills and process knowledge, but also the beginning of innovative practice and the enlightenment of innovative spirit.

Second, the training content

Training Project 1: Safe Use of Electricity

We must realize the importance of using electricity safely.

The knowledge of safe use of electricity is about how to prevent accidents and ensure the safety of people and equipment. In electronic assembly and welding debugging, various tools, electronic instruments and other equipment should be used, and dangerous high voltage should be contacted at the same time. If you don't master the necessary safety knowledge and lack sufficient vigilance in operation, personal and equipment accidents may occur. Therefore, on the basis of understanding the harm of electric shock to human body and the causes of electric shock, we must master some knowledge of safe use of electricity to prevent problems before they happen.

(2) Electric shock and related protective measures

1. Electric shock type: (1) Electric injury, which usually includes burns, electric burns and skin metallization. The damage caused by electric injury to human body is generally non-fatal. (2) Electric shock refers to an electric shock accident in which an electric current flows through the human body, seriously affecting the human body's breathing, heart and nervous system, causing muscle spasm and nervous disorder, leading to respiratory arrest and serious life-threatening. Most electrocution deaths are caused by electric shock. It is the current flowing through the human body, not the voltage, that determines the intensity of electric shock.

2. Factors affecting the degree of electric shock injury to human body: current size, current type, current action time, current path and human body resistance. The resistance of human body will change with the dryness of human skin and the age of people. When it is dry, it can show more than 100 000 ohms, and when it is wet, the resistance can drop below 100 0 ohms, and it will increase with the age of people.

3. Causes of electric shock: direct electric shock, indirect electric shock, electrostatic electric shock and electric shock caused by step voltage. 4. Technical measures to prevent electric shock: (1) protective grounding and protective grounding (2) electric shock protection device.

There is also a very important point, if you really see someone get an electric shock, what measures should be taken. First, make sure to disconnect the power supply or remove the wire from the person who gets an electric shock with an insulator. If the electrocuted person stops breathing but still has a heartbeat, he should be given artificial respiration or chest compressions.

III. Training Summary or Experience

There was an electronic electrician training in the first week, and the master told us about the safe use of electricity, which is related to our daily life, and let us have a further understanding of how to use electricity safely on the basis of the original. Through the teacher's explanation, I learned the basic knowledge of safe use of electricity, understood the importance of safe use of electricity, and laid the foundation for electrician, electronic training and safe use of electricity in my future study, work and life. During the one-week electronic and electrical training, the master also gave us a general description of the future training plan, and explained some requirements and precautions, which also made me full of expectation and curiosity about the future training.

In the second week, we assembled the lighting circuit. After listening to the teacher's introduction of our course content, we began to do it. We are a group of two. We'll connect the wires ourselves, and then turn on the circuit to make the lights come on. I'm glad to see the light I assembled turned on. When the master came to sign the autograph, he probably thought that we shared our joy like children and signed it for us with a smile. This time, our group went smoothly. Although there were some minor problems in the process, under the patient and meticulous explanation of the master, it did not become an obstacle for us to correct them in time. The master always points out our problems, gives us correct guidance and teaches us how to find out what is wrong. In this practical operation, I have a preliminary personal experience of what an electronic electrician looks like. Through this assembly, we know what incandescent lamps and fluorescent lamps are and the basic composition of their lighting circuits.

In the third week, we carried out a project using commonly used electronic instruments. Under the teacher's explanation, we began to operate after understanding the functions of common electronic instruments such as DC regulated power supply, multimeter, signal generator and oscilloscope. I measured the square wave of the calibration signal with an oscilloscope, and got the following data: the peak value of the sine wave with a period of10.44V and a frequency of 0.096Hz 1.5KHz and 10dB is 5.5V, the peak value is 2.75V, and the period is 17mA. Through this lesson, I have mastered the basic usage of DC regulated power supply, multimeter, signal generator and oscilloscope, and laid the foundation for my subsequent training. F is 2.75 Hz.

In the fourth week of training, we conducted the understanding and testing of common electronic components. At first, through the teacher's explanation, we simply understood the role of resistance, potentiometer, capacitor, inductor, diode, triode, integrated circuit chip and other related knowledge. In the process of training, we should know all kinds of common electronic components in kind, master the reading method of common electronic components parameters and the method of measuring common electronic components parameters with multimeter. In the reading of color ring resistance, I read a four-ring resistance, whose color ring is orange, black, red and silver, and the resistance value is 30 _ _100 5%, which is measured by a multimeter as 2.9 kiloohms. It can be compared that it is almost the same, which proves that the previous reading is correct. Then the maximum resistance of the potentiometer is 0.0 1 milliohm measured by multimeter; The capacitance measured by multimeter and multi-purpose adapter socket is 0.0 1 milliohm. In this lesson, I learned to distinguish the pins of diode and triode. After completing the above steps, we prepared the experimental circuit of diode. When I connected the circuit and turned on the power supply, the diode lit up and the circuit was connected successfully. Through this simple experiment, I learned the functions of common electronic components and deepened my understanding of circuit connection. In the second class, we started our welding technology and welding training on the basis of the first class. Also under the detailed and serious explanation of the master. Familiar with the basic knowledge and requirements of electronic assembly and welding technology and start operation. What we have to do is the welding practice of printed circuit board. We solder components on the universal circuit board according to the circuit diagram. The first component I just started welding was a diode, and the soldering iron and tin in my hand kept shaking uncontrollably. I keep telling myself to be steady, but my hands are still shaking. Maybe it's the first time I'm nervous. My first welding attempt ended with my hands shaking. But maybe I really know what welding is all about. I know I have a bottom. I do a lot of second welding, and my hands don't shake much. The more I weld, the more skilled I become. With experience, you can weld well afterwards. It's time in the morning, my colleagues haven't finished welding, and I haven't finished welding. The master said to go back first and come back in the afternoon to continue.

In the fifth week, welding technology and training continued, and the teacher also talked about the production of AS-06FM radio. Colleagues who finished the last project can continue to do this project. In the afternoon, we all arrived early. As soon as we arrived, we sat down to continue the welding work in the morning. Without the fear and tension in the morning, I got started as soon as I picked up the soldering iron, not to mention it was really good. At this time, after these days of training, we all have the posture of electricians. When I arrived, I saw some colleagues who arrived earlier than us. When welding, I felt like I was in an electric factory, which was different from what I felt at first. The class didn't last long,

I'm still trying to weld carefully, and some colleagues have succeeded. Although I am a little slower than other colleagues, I am still steady. I don't think we can make any mistakes until we finish it for the last time, so we should weld it carefully and slowly. After almost an afternoon's efforts, the unstable multivibrator circuit was finally welded. At this time, the most critical moment has come, because I will use the DC regulated power supply I have learned before to conduct the power-on test. I connected the connection circuit with tension and expectation and pressed the output key. At this time, I saw two light-emitting diodes flashing in turn, and I thought it was really beautiful. My mood at this time can really be described as being elated. The feeling of hard work and sense of accomplishment is really good. Compared with the previous content, this training content takes more time and gains more. I think I'm not afraid of anything after this welding. Moreover, I have a preliminary understanding of electronic assembly welding technology, and common welding and assembly workers have mastered the correct use of welding tools and common tools and manual electronic welding technology, laying a foundation for preparing for the installation of practical products of radios in the future.

The sixth and last week of electronic and electrical training. Today, the content of our training is the production of printed circuit board (PCB) and circuit debugging. Under the teacher's explanation, we learned the basic process of making PCB circuit diagram. According to the process described by the master, we successfully completed the task, which made me familiar with the basic operation of making PCB and mastered the operation of making PCB by thermal transfer.

Finally, with nostalgia, this period of time is over. With the careful guidance of the master, the active help of my colleagues and my earnest efforts, the training ended successfully. Get to work!
