Maintenance electrician technical summary report 2
Maintenance electrician work summary I have participated in the work since January, by the plant after three levels of education to the electrical workshop maintenance class, engaged in electrical maintenance work, the work of strict requirements for their own, open-minded to masters, colleagues, and through the combination of theory and practice, so that their own business level continues to improve, has participated in a number of times or independently to undertake the installation and renovation of electrical equipment projects, and for many years was awarded awards. Installation and renovation projects, and for many years by the unit awarded advanced workers, safety producers and other honors.
In 1992, due to the production needs of the plant's two new nitrogen and hydrogen compressor, the electrical part of the 1250kw/6kv synchronous motor, I was honored to participate in the installation of the whole process of the project, from the positioning of the trunking, the production of iron to the wiring of the high and low cables, from the motor testing, wiring, to the high-voltage switchgear installation and commissioning, as well as the site of the control cabinet of the mechanical debugging, auxiliary switch adjustment, and high-voltage cable head production, the first time to the high voltage cable, and the first time to the high voltage cable. As well as the production of high-voltage cable head, the first contact with the installation and commissioning of kglf-11 type excitation cabinet, and from learning some technical points of synchronous motor installation, so that they have a new improvement.
In the work of not sticking to the rules, dare to innovate is an excellent maintenance worker must have the advantage of my synthetic maintenance class responsible for the electrical equipment power supply load accounted for about 60% of the plant's total load, just 6kv high-voltage synchronous motors ranging in size from 620kw to 3,100kw motors there are 15, plus matching a variety of asynchronous motors, etc. More than 200 units, which is only 6kv for the 6kv synchronous motor to 3100kw size motor, and so on, the motor is a good choice. More than 200 units, which for only six or seven people in the maintenance class, the daily workload can be imagined, especially in the summer due to the rising ambient temperature caused by the synchronous excitation cabinet failure, often plagued us, in the tedious repetition of the work, I noticed that synchronous machine excitation cabinet in the operation of the transformer, the high temperature emitted is the excitation of the control circuit of the parameters of the electronic components of the main reason for the changes that lead to the system out of control, resulting in equipment failure, thus leading to the loss of control. Lead to the system out of control, causing equipment failure, so I put forward to the workshop leadership to transform the excitation cabinet idea, after repeated demonstration by the leadership of the rectification of the original excitation cabinet of the transformer from the cabinet to separate out, placed in a special transformer indoor heat dissipation, the control circuit with a 38w axial fan to replace the original 800w fan for cooling, which not only reduces the noise and optimize the operating environment, which has been plaguing us for many years, so that we have to work for a long time, the control circuit of the excitation cabinet. This reduces noise and optimizes the operating environment, so that the problems that have plagued us for many years have been solved. Until now, we have completed the replacement of the original electronic plug-in analog control with an intelligent modular controller, which has completely solved the problems in the operation of the equipment and stabilized the production.
The continuous improvement of the business level comes from the process of accumulating experience in practical work. ____ to ____ the enterprise due to the expansion of production, I have participated in the installation of 75 tons of boiler electrical high-voltage part of the installation, 4.4 meters changeover project, 1200kwa transformer and low-voltage distribution room installation project, 1.6 meters synthesized 1300kw electric furnace installation project, etc., in the installation of the synthesis tower electric furnace in the project I have repeatedly tested and figured out the assembly of the synthesis tower of the electrode rod of the small cover a set of Successful experience, with our pre-manufactured mold into the electrode rod equipped with mica tube small cover, winding fine asbestos rope smeared with silica gel (high temperature) between the mold and the electrode rod with a 5-ton jack once pressed into shape, and then dry, so that the top of the pressure instead of nut screwing pressure method. Ensure the stability of the electrode rod assembly process, so that in use not only to withstand the impact of 320 kilograms of other high-pressure, but also to withstand the test of the high temperature of 490 °, our factory has ended the history of hiring outside technicians to solve the problem.
____ September because of outstanding work performance, I was transferred to the urea maintenance class as a team leader, during this period, I have organized the installation of 6kv/850kv high-voltage motor project, ____ year our class has undertaken the plant's new transformer adsorption distribution room, including 1600kva transformer, including a full set of engineering projects, as well as the new 620kv/6kv change off the pump motor installation and commissioning, air pressure station 90kv transformer pump motor installation, commissioning, air pressure station 90kv transformer pump motor installation, installation and commissioning, the new 620kv/6kv transformer pump motor installation. Installation and commissioning, air pressure station 90kw air compressor plc installation and commissioning, etc., due to the urea process environment corrosive, electrical equipment scattered, ____ year I organized personnel to one, two urine distribution room all inverter rectification, respectively, the formation of a special inverter room, purify the environment, but also reduce the failure, and realize the general control room operator screen surface detection and centralized control, so that the original operation of the Simple and easy to use, at a glance, but also to facilitate the maintenance staff overhaul, maintenance.
Enterprise production, safety first. This is especially for our staff engaged in hazardous industries, the significance of more significant. The use of mastery of technology to solve the problems in production, is a technician incumbent responsibility. ____ summer, I was in the urea packaging section inspection found under the feet of the operator sewing machine control switch is 380v power supply voltage, so I sprouted the original 380v control circuit into 36v safety voltage control, after the transformation of the solution to the potential safety hazards, to achieve the purpose of safe production.
Twenty years of work experience tells me that to be a good technician, not only to have hard-working, excellence, the spirit of continuous improvement, but also must have a bold and careful, flexible and innovative character, I am proud to be a good technical workers.
Maintenance electrician technical summary report 3
Maintenance electrician technical summary of the turn of the eye pieces, ____ year has passed, looking back to come to dedication to the work of this period of time, so that I recognize the importance of the power supply car and their own business skills lack of subjective facts, so that I recognize from the heart of their own only to learn the professional skills in order to ensure that the production of the normal use of electricity, safe use of electricity.
Remember the day of the apprenticeship test, Jingye station 4 # variable sudden power outage, resulting in the south team jurisdiction: 65 square meters with burning 1 section, 7 # 8 # furnace 2 sections and the new 1 # furnace distribution room 1 section 2 sections of the busbar all power outage. The blackout accident not only affects a large area of normal production, the most serious because of the blackout in the new 1 # furnace safety accidents, the accident fully proved the importance of power supply, so as the power supply maintenance workers themselves, to have a high degree of responsibility to ensure the normal operation of the power supply system.
In each equipment overhaul, see the master of each master of the look of success, so that I feel their own knowledge is shallow, can not do a good job for the master's helpers feel guilty. Therefore, I should strengthen the study, and strive to catch up in a short period of time, in the work of the higher leadership and master's good helper.
These months of work, in fact, but also found that I still have a lot of problems, such as: the bottom of the standard of work, the lack of responsibility, laziness, etc. can directly affect the work of the problem, so, in the future work and life to work harder to change their own shortcomings, so that their work on a new level.

I. Purpose and significance
Through the practical training, for students to prepare for the future of the professional experiments, graduation design of the necessary process knowledge and operational skills, while cultivating students rigorous work style and good work habits. It is both an introductory guide to basic skills and process knowledge, and the beginning of innovative practice and the initiation of the spirit of innovation.
Two, practical training content
Practical training project one: safe use of electricity
(a) must recognize the importance of safe use of electricity
Safe use of electricity is about how to prevent electrical accidents and to protect the safety of people and equipment knowledge. In the electronic welding debugging, to use a variety of tools, electronic instruments and other equipment, but also contact with dangerous high voltage, if you do not have the necessary safety knowledge, the operation of the lack of sufficient vigilance, may occur personal, equipment accidents. So we must understand the hazards of electrocution on the human body and the causes of electrocution on the basis of some knowledge of the safety of electricity, to do before it is too late.
(B) electric shock and related protection measures
1. Types of electric shock: (1) electrical injuries, electrical injuries are usually burns, electric branding injuries, skin metallization of three kinds. The harm caused by electrical injury to the human body is generally non-fatal. (2) electric shock, refers to the electric current flowing through the body, seriously affecting the human respiratory, cardiac and nervous system, causing muscle spasm, nerve disorders, resulting in respiratory arrest, seriously endangering the life of the electrocution accident. Most deaths from electrocution are caused by electric shock. Decide the intensity of electric shock is the current flowing through the body, rather than voltage.
2. Factors affecting the degree of injury caused by electric shock: the size of the current, the type of current, the current time, the current pathway, the human body resistance. Human body resistance will change with the dryness of human skin and the age of the person. Dry can present more than 100 000 ohms, two wet, the resistance can drop to less than 1000 ohms, and with the increase in human age and become larger.
3. Reasons for electrocution: direct electrocution, indirect electrocution, electrostatic electrocution, electrocution caused by cross-step voltage. 4. Technical measures to prevent electrocution: (1) protective earthing and protective zero (2) electrocution protective devices
Another important point is that if you really see someone else electrocuted, what kind of measures should be taken. First ensure that the power supply is disconnected or insulator to remove the wire from the electrocuted person, if the electrocuted person's breathing stops but there is a heartbeat, it should be artificial respiration or extrathoracic cardiac compression.

Three, practical training summary or experience
The first week when I carried out the practical training of electronic and electrical engineering, the master gave us the knowledge of the safety of electricity, this is related to our daily life, and let us on how to safely use electricity and other knowledge in the original basis for further understanding, through the master's explanations, I learned the basics of safe electricity, know the importance of safe electricity, and this is the important significance of this The important significance of electricity, and this for the electrician and electronic training and the future of learning, work, life in the safe use of electricity to lay the foundation. A week of practical training in electrical and electronic engineering, the master also roughly described to us the future of the practical training program and explains some of the requirements and precautions, which also makes me full of anticipation and curiosity about the future of practical training.
The second week we carried out the assembly of lighting circuits, after listening to the master to introduce the content of our class, we began to do. We were a group of two people, do it yourself to connect the wiring, and then turn on the circuit, so that the lights on. It was great to see the lamps we assembled light up. When the master came over to sign our names, he probably also felt that we were like children, sharing our joy, and smiled as he signed our names for us. This time our group went very smoothly, although the process also encountered some small problems, but in the master's patience and careful explanation of our timely correction is not an obstacle, the master can always pinpoint our problems and give us the right guidance, and at the same time taught us how to find out what went wrong. In the process of this hands-on let me initially experience how the electronic electrician. Through this assembly let us understand what is incandescent lamps, fluorescent lamps and incandescent lamps, fluorescent lamps and the basic composition of the lighting circuit.
The third week we carry out the use of commonly used electronic instruments this program. We understand the master's explanation of the function of the DC voltage regulator, multimeter, signal generator, oscilloscope and other common electronic instruments and then began to operate. I use the oscilloscope to mention the calibration signal square wave measurements to get the following data: the peak value of 0.44V, the period of 10.4mA, the frequency of 0.096Hz; measured 1.5KHz, 10dB sine wave peak-to-peak value of 5.5V, then the peak value of 2.75V, the period of 17mA, then the period calculated from the frequency, and the frequency of the display compared to the difference is small. Through this class I mastered the DC regulated power supply, multimeter, signal generator, oscilloscope basic use, which also laid the foundation for my subsequent practical training. f is 2.75Hz
The fourth week of practical training we carried out is the knowledge and detection of common electronic components. At the beginning of the master's explanation we simply understand the resistors, potentiometers, capacitors, inductors, diodes, transistors, integrated circuits, chips and other components of the function and some other knowledge related to them. In the process of practical training I recognize a variety of commonly used electronic components through the physical and mastered the commonly used electronic components parameter reading method and the use of multimeter to measure the parameters of commonly used electronic components. In the color ring resistance reading I read a color ring for the orange, black, red and silver four-ring resistor resistance value of 30 ___ 100 ± 5% and measured with a multimeter resistance value of 2.9 kilo-ohms, can be compared to similar, which proves that the previous readings are correct; and then use the multimeter to measure the potentiometer's maximum resistance value of 0.01 milli ohms; with a multimeter and the multi-adaptor plug seat capacitance of 0.01 milliohms; and the multimeter and multi-adaptor plug seat capacitance of 0.01 milliohms, the multimeter and the multimeter to measure the capacitance of 0.01 milliohms. capacitance of 0.01 milliohms, and I learned in this class to identify the diode and transistor pins. After doing the above steps, we prepared an experimental circuit for diode, I connected the circuit and turned on the power and the diode lit up, so the connection of the circuit was successful. 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 process and welding training on the basis of the first class. Also in the master's detailed and serious explanation. We are familiar with the basics of electronic soldering process and the requirements of the hands-on operation. We are going to carry out is the printed circuit board welding practice. We are in the universal circuit board in accordance with the circuit diagram for the welding of components, I just began to weld the first component is a diode, the hand holding the soldering iron and tin has been uncontrollable shaking, I have been saying to myself to be stable, but still the hand is very trembling, perhaps the first time to contact the nervousness is unavoidable. My first attempt at soldering ended with my hands constantly shaking. But maybe it is really understand the welding is how it is, know the bottom of the heart, the second welding I welded much better, the hand does not shake more, and the more welding the more skillful hand. After having experience, I welded very well afterward. When the morning time, colleagues have not finished welding, I am also the same, the master said first back, come back in the afternoon and then continue.
The fifth week we continue to welding process and welding training, while the teacher also talked about the production of AS-06FM radio, do the last project colleagues can go on to do this project. In the afternoon we all arrived early, once we arrived to sit down to continue to carry out the welding in the morning, there is no morning fear and nervousness, this time I picked up a soldering iron on the hand, do not say really ` is also a model, this time we have after these days of practical training have the electrician's frame, we came to see there are more than we arrived earlier than our colleagues in the welding feel as if into the electric factory, which is different from the beginning of the feeling of the This is different from the feeling at the beginning.
I was still working hard on my welding when a colleague succeeded. Although I was a little slower than other colleagues, but I'm still very stable, I think we can not get at the end of the time did not come to error ah, so I do not slow down a little bit of serious welding. After almost an afternoon of hard work I finally welded a good unregulated polyharmonic oscillation circuit welding, this time the most critical moment came, because then it is to be used before learning to use the DC regulated power supply power test, I connected with nervousness and anticipation of the mood connecting the circuit, press the output key, then I saw two light-emitting diodes take turns to put the light, flashing, I think it is really! I think it's really beautiful, my mood at this time can really be described as a blossoming heart. That kind of serious efforts to get the feeling of harvesting that sense of achievement is really good. This practical training content than the previous content to spend more time to harvest more. I feel that after this welding, I'm not afraid of what I'm asked to weld. And then I have a preliminary understanding of the electronic welding process and commonly used welding, assembly workers, mastered the welding tools and the correct use of commonly used tools and manual electronic welding technology for the future preparation of the radio training product installation laid the foundation.
Electronic electrician practical training in the sixth week is also the last week of training. Today our practical training content is the production of printed circuit boards (PCB) and circuit debugging, in the master's explanation we understand the basic process of making PCB board circuit diagrams, in accordance with the master's said process, we smooth and successful completion of the task, so that I am familiar with the production of PCB boards the basic operation of mastering the use of thermal transfer printing to produce PCB board operation.
Finally in my nostalgic mood this time so ended. In the master's careful guidance and colleagues actively help and my serious efforts, the successful conclusion of practical training. Received into the workplace!
