From a number of aspects, the maintenance for the personnel need to have the knowledge and skills to summarize, through the teaching training to obtain professional skills at the same time, but also need to be based on the actual situation of the maintenance of their own electricians to strengthen their training, so that they can continue to meet the requirements of the times of progress.
A modern maintenance electrician skills requirements
(a) the level of professional knowledge of maintenance electrician
Maintenance electrician is engaged in mechanical equipment and electrical system lines and devices installation and maintenance and debugging, repair professionals. It is the technical assurance personnel in the back of the production of electric power enterprises, and its purpose is to ensure the safety and use of electrical equipment. From this we can see, maintenance electrician in the process of carrying out the work must be according to the corresponding professional knowledge and skills. These skills mainly include several calculation methods commonly used by electricians, the use of commonly used testing equipment and operating methods, maintenance electrician work quality supervision and management, commonly used electrical components of the test, selection and access, maintenance electrician reading basic skills, electrician safety technical operation requirements, machine tool electrical equipment maintenance and protection, maintenance electrician operating skills. Maintenance electrician's professional skills to a certain extent so that maintenance workers to carry out line maintenance of the basic work to ensure that they are also as maintenance workers must have the professional quality.
(B) maintenance workers operating skills
Maintenance electrician's main responsibility is responsible for the power system and transmission equipment maintenance and protection work, so the current employment situation, maintenance electricians need to master a large number of practical operating skills, only then can effectively adapt to the needs of the work, maintenance electrician in the process of carrying out the work of the operating skills should be mastered, including the installation of commonly used electromechanical equipment, the installation of electrical and mechanical equipment. Including the installation and maintenance of commonly used electromechanical equipment, the installation and maintenance of grounding devices, as well as a variety of power system operation in the process of equipment maintenance and maintenance and other practical skills. For maintenance electricians, the actual hands-on skills in the entire work process occupies a large proportion, therefore, the actual hands-on ability is very important. If the maintenance electrician does not have a solid foundation of professional and technical skills, even if they have a strong practical ability is no way to complete the normal electrical maintenance work. Therefore, we can see that maintenance electricians also need to constantly exercise their practical ability and practical ability, and constantly improve their professional skills, because only with professional technical knowledge can be skillful in practice to apply the knowledge to the actual work, so as to ensure the normal operation of the power system.
Second, how to improve the skills of maintenance electricians
(a) professional skills training
For any technician, the premise of the smooth completion of the work can not be separated from the good operating techniques, and the skills of maintenance electricians is not out of thin air, their skills need to have professional technical knowledge as a guarantee. Therefore, for maintenance electricians, the premise of skilled work ability is to have professional technical knowledge. Therefore, in order to improve the skill level of maintenance electricians, maintenance electricians to carry out education Oh training is of great practical significance. In the training process need to maintenance electrician's professional knowledge for systematic training. As a maintenance electrician technicians, their education in the education stage must have received a system of professional knowledge education and, but with the progress and development of the times, a lot of knowledge system has not been able to meet the needs of the times, so it is necessary to maintenance electrician training harness, enterprise management departments in the process of carrying out the training work, the need for the enterprise electric power work for the maintenance of electrician's professional knowledge of the integration, is that they can better master the use of each application, the maintenance electrician's professional knowledge, the maintenance electrician's professional knowledge is very important. They can better grasp the use of these professional knowledge, and gradually form their own professional skills system, only then can effectively enhance the professional skills of maintenance electricians.
(B) strengthen the maintenance point electrician's observation
For the maintenance electrician, such a group of people to do is to find out the power system in the process of operation of the omission and the existence of faults and problems, and can be timely to solve this problem, to promote the stability of the power system, the safe operation of the power system. Therefore, for this feature of the work of electricians, maintenance electricians are required to have a keen observation. To improve the observation of maintenance electricians in the daily work process must continue to cultivate the observation of electricians, in the process of line checking, and strive to do not miss a single problem, and should also develop patience, careful character, after checking out the problem can be taken in a timely manner measures to solve it. But the cultivation of observation is not an overnight thing, which requires the business sector and maintenance electricians on both sides *** with efforts, business management should strengthen the encouragement and rewards for electricians, maintenance electricians also need to constantly remind themselves to pay attention to the process of work and constantly find the smallest problems, only then can be conducive to the improvement of the professional skills of maintenance electricians.
(C) maintenance electrician through their own efforts to raise too high skills
First of all, the maintenance electrician to have the spirit of continuous learning and motivation, for the modern electrician for the maintenance of new technologies and new knowledge to continue to learn and understand, through their own efforts to effectively improve their professional skills. Under the constant development and change of the times, the electrician knowledge is constantly updated, which puts forward a higher maintenance electrician his requirements, maintenance electrician in the deep professional knowledge at the same time also need to continuously strengthen the learning of new knowledge, through the work while learning to improve themselves. In addition, in addition to having new knowledge and new skills ultraviolet, maintenance electricians also need to have a sense of innovation. In the original ability to work on the basis of continuous technological innovation, so as to obtain new operating skills. At the same time, it is also necessary to strengthen the ideological awareness of electricians to improve, for example, electricians should have a strong sense of autonomy, competition and innovation. Only a comprehensive guarantee of the overall quality of the electrician, in order to further enhance the skills of maintenance electricians.

Maintenance electrician technology essay example two: "Try to talk about the maintenance electrician troubleshooting skills"
Abstract: Nowadays, in the continuous progress of science and technology and the rapid development of the economy under the influence of the power of China's life and production in all aspects of life and production have been more and more widely used, power has become an extremely valuable resource, symbolizing the social Progress, we need to use and create. However, electricity is also very dangerous, therefore, we should put the safety of the use of electricity in the first place, this article mainly introduces the maintenance electrician troubleshooting skills.
Keywords: troubleshooting; safety; solution
Ensuring the safety of a region's life and production of electricity is the main responsibility of the maintenance electrician, maintenance electricians through a comprehensive inspection of the power system, timely troubleshooting, and can rely on their own skills and past experience in the work of the shortest possible time will be eliminated, so as to ensure that the residents of the production of electricity and normal demand for electricity. Normal demand. Today, China's power is very widely used, while the power equipment also shows a trend of diversification and complexity, so the electrician must continue to strengthen the experience and skills, enrich their professional knowledge.
First, the common power failure
In any enterprise or institution, the electrician is indispensable, the electrician must be able to accurately and timely judgment of the power system failure, which requires that the electrician must be very familiar with the circuit maintenance knowledge, and in accordance with the specific conditions of the problem of flexible processing. In fact, the failure of the power system is mainly the usual maintenance and repair, line debugging normal or not, as well as the installation of equipment and wires reasonable or not. Electricians can judge whether the power system is healthy and normal work through the observation of the lighting zero degree of stability and normal or not. Usually, unreasonable commissioning and installation may cause lighting anomalies, common short-circuit, circuit breakers, and even leakage may occur in serious cases, therefore, the electrician must be able to accurately analyze the root cause of power system failures, and then take effective measures to solve. In addition, transformer failure is also very common, if the long time use of transformers will appear insulation, overheating and other phenomena, therefore, electricians in ordinary times should do pay attention to observation, frequent testing of the transformer, the installation of insulated ceramic tubes and oil protection of both methods can effectively avoid the occurrence of failure. There is also a motor failure, it mainly contains shaft cracks, shaft core wear, rotor bending, etc., in the shaft grain wear more serious places should be replaced in a timely manner; once the shaft core wear, should be accurately welded, if the wear and tear is too serious, then you can use a machine tool to process; if the rotor is bent should be taken out, and then based on the power system of the structure of the different different repair, ensure that the motor can operate normally. Maintenance to ensure that the motor can run normally.
Second, the specific method of eliminating power failures
The electrician must have professional knowledge and sufficient theoretical principles as a basis, so that the failure to immediately and accurately determine and analyze, the following are several commonly used methods of eliminating power system failures are introduced to you.
1. Step-by-step queuing method and debugging parameter method
The so-called step-by-step queuing method, is the occurrence of a short circuit, the use of step-by-step means of excision, one by one, to analyze the specific location of the failure, and then the power system failure. The debugging parameter method is more suitable for use in the power system inside the original is not damaged, the line normal contact. If the power user does not correctly use the voltage or debugging will make the power supply system can not work properly, and the power system can afford the amount of electricity is also limited, not unlimited use, so, debugging parameter method is the most suitable.
2. Alternative method and short method
The so-called alternative method, is unable to determine the cause of the failure and the specific location used, if the electrician suspects that there is a part of the system or a part of the failure, you can choose to use other parts of the original parts to be replaced down to observe that after the replacement of the power system can not run normally, the efficiency of this method is relatively low. This method is less efficient and is suitable for troubleshooting in those simpler structures. Usually, the short connection method for circuit current is small, the voltage is also lower in the power system, first of all, the electrician in accordance with their own rich experience over the years on the occurrence of short-circuit location for the approximate judgment, and then shorted with a wire to determine the correctness of the electrician's judgment, the use of this method the electrician must ensure that their own skills are highly skilled, experienced, especially troublesome, and now our country has been very rare for the use of this method. Rarely seen, but some poor places are still using this method.
3. Resistance, current and voltage measurement method
Voltage measurement method, refers to the rational use of the multimeter, the multimeter's voltage gear in accordance with the actual power voltage adjusted to the most appropriate position in order to be able to accurately measure the fault judgement criteria that is, to observe the measurement of the circuit and the electric shock has not occurred on and off, or produce intermittent conditions. Current measurement method is used is the ammeter in the determination of the circuit when the size of the current value is not normal and stable or not, which should be in accordance with the actual situation of the local power to judge the current measurement method is relatively convenient, but it is also very easy to occur in the measurement of the error, due to the user's intensity of the electricity is different at different times, so the measurement of the current is a little difficult to be used for the production of the usual circumstances Usually, it is used for power measurement in workshops or factories. Voltage measurement method and resistance measurement method is similar to the rationale for the two, are to observe the line or the abnormal condition of the electric shock, this method is relatively safe, is less developed places will usually choose the power measurement.
Third, strengthen the maintenance electrician troubleshooting skills
An enterprise to form their own production capacity is the most important material basis for the equipment, should make the equipment in the process of life and production to maximize their role to play out in the actual operation process, should comply with the prevention of the main plan for overhaul, maintenance, and the use of a combination. Equipment failure is very diverse, more specialized, the problem is also particularly complex, both units and individuals should continue to strengthen and improve their troubleshooting skills to minimize losses.
Enhancement of the mechanic's ability should be mainly from the following two aspects: the first is a solid professional knowledge. In this era, information is constantly changing, knowledge has been updated, maintenance electricians can not meet the status quo, usually should pay attention to more learning, skills exchange, participate in professional lectures, understanding of advanced science and technology in order to improve their theoretical knowledge, and in practice, through troubleshooting, and strive to work in the work of the more reforms and innovations, the actual work and theoretical knowledge fused together to enhance their level and ability. Enhance their own level and ability. Another is to have good professional ethics. In the event of equipment problems do not blindly judgment, to listen to the views of others, and others to communicate in a timely manner. For the problematic equipment should be timely maintenance and report, make a good record.

Maintenance electrician technology essay example three: "Talk about the electrical professional maintenance electrician senior mechanic's learning"
According to the requirements of the "Maintenance Electrician National Occupational Skills Standards", the senior maintenance electrician theoretical knowledge assessment scope includes: relay control circuits, AC and DC drive systems, electronic circuits, and other knowledge of map reading, mapping, analysis, debugging and maintenance. The depth of the assessment requires mastery of electrical mapping steps and methods, familiar with the composition of machine tool circuits, principles and common failures; mastery of the basic command table of PLC, familiar with programming skills, master the use of programming software, familiar with the types of common PLC failures and solutions, etc., of which the programmable logic controller theoretical knowledge points and practical exercises accounted for 30% or more. From the demand of modern life or the direction of industrial development, all need high skill compound talents. It can be imagined that the programmable controller learning needs to be constantly in-depth. In a number of senior maintenance electrician theoretical knowledge training assessment, robotics topics have appeared many times, from the professional knowledge point of view, robotics learning a wide range of comprehensive knowledge, involving more knowledge; from the logical thinking point of view, in the modernization of production and life, the gradual refinement of the division of labor in society, the production equipment is becoming more and more sophisticated, more and more complex automation of production equipment, robotics control refinement, and at the same time, it can be good exercise of students' logical thinking aspect. Good exercise students logical thinking ability.
First, the background of the robot
The robot is a new type of device developed in the process of mechanization and automation of production. It is an important branch of robotics. Characterized by programming to complete a variety of expected tasks, in the construction and performance of both human and machine respective advantages, especially reflecting the human intelligence and adaptability. In the modern production process, manipulator is widely used in automatic production lines, although the manipulator is not as flexible as the manpower, but it has the ability to constantly repeat the work and labor, tireless, not afraid of danger, the power to grasp and lift heavy objects than the manpower force, therefore, the manipulator has been the attention of many departments, and more and more widely used.
In 1958, the United States United Controls developed the first manipulator. In 1962, the United States United Controls made a trial of a numerical control teaching reproduction type manipulator. In the same year, the U.S. Machine Manufacturing Company also tested a successful robot called Vewrsatran, the robot's central column can rotate, lift, hydraulic drive control system is also taught to reproduce the type. These two types of robots appeared in the early 1960s, is later the basis for the development of foreign industrial robots. At present, most of the manipulator still belongs to the first generation, mainly relying on manual control; the direction of improvement is mainly to reduce costs and improve accuracy. For our maintenance electrician advanced workers to learn the robot is more complex, through my teaching and observation, found that the students' learning methods and skills still need to be improved.
Second, the structure and working principle of the robot
Combined with the maintenance electrician certification and the "National Occupational Skills Identification Standards" requirements, our school and the enterprise jointly developed for the certification training simulation of the robot, is divided into three modules: (1) feeding mechanism; (2) gripping mechanism; (3) sorting system; pneumatic control using solenoid valves. Feeding mechanism has material detection, when the material slot has material, material detection sensor will send a signal, through the program control solenoid valve, feeding cylinder to launch the material, waiting for the manipulator to grasp; gripping mechanism has three degrees of freedom control, each degree of freedom are provided for the initial position, when the material is placed in the specified position, the manipulator begins to move down, clamping the material; the process requires position sensors to detect the material grasping This process requires position sensors to detect the accuracy of the grasped material; after taking, the manipulator has to put the material in the sorting system. The system is driven by the conveyor belt, material detection, color detection, metal detection, combined with the actual production of enterprises, sorting to different receiving place. Manipulator control involves pneumatic, solenoid valve control, sensor detection, mechanical position adjustment, hardware circuit wiring debugging comprehensive ability to train, so it is more difficult to learn. After 3 years of teaching, summed up their own set of learning methods.
Third, the robot learning
For the robot, modular learning is very important to use according to the function of each module to do exercises, so that learning will be very easy to get started. The following describes the modular step-by-step learning methods and precautions.
(1) For the robot structure, we divide it into 3 modules to learn, as shown in Figure 1. Feeding unit, handling unit, sorting unit; the first module feeding detection unit, this module can be divided into material detection, push material, cycle feeding; material detection is mainly used in the feed port, and when needed, the material in the bin will be sent to the gripping and handling platform, ready for the handling unit. In the material detection process need to pay attention to adjust the sensitivity of the detection sensor, because this is the first step in the first step of the robot handling process, if there is an error in the detection here may lead to the failure of the handling unit process. This process needs to cycle, the next time when to start pushing the material depends on the robot to the first time the material is safe and error-free handling to the designated location, which is the material supply unit in the process of writing the program to pay attention to.
(2) handling unit, in the entire handling system, this link is the most important and complex. Involving mechanical knowledge, pneumatic control, sensor knowledge, PLC program control design and other aspects. In the robot handling process involves many sensors limit control, each action needs to be detected by the sensor, then in the robot from the original position to start stretching out, descending, grasping, rising, rotating, descending, releasing, rising, turning to the original position, the process needs to be adjusted for each solenoid valve action sequence, which is the first step; and then the need for each action to be accurately in place, which will affect the grasping of materials. How to ensure that the material is accurately grabbed, here to step by step. Grab the action step by step refinement, each of the above action sensor detection is accurate in place in the overall debugging, which can be avoided in the debugging process to repeat the adjustment of the accuracy of the robot gripping. Program writing also has a variety of different types of PLC models, there are different ways of writing, focusing on the Mitsubishi FX2N model PLC, we all know that the general instructions are written without problems, pay attention to the whole process of the manipulator action step by step after the preparation to ensure that the completion of each action can be reset. Comparison with other PLCs to take the general instructions written without much difference, but to take the stepping instructions written, here is very simple. Mitsubishi FX2N-PLC stepping instruction has a great advantage is that it is each step of the program action is completed, the next step does not need to consider its reset, which can greatly simplify the amount of robot handling process procedures, and the general instructions compared to a lot of simple.
(3) sorting unit, as the final sorting system, we can correctly recognize the function of each sensor, the corresponding material detected by the sensor to stream out can be written in this process there are two ways. One method is in accordance with the order of action to the sorting unit when writing; another method is at the beginning of the robot action, that is, the original position of the sorting system when the program to join the robot to complete the gripping action back to the original position at the same time to start sorting materials, but also does not affect the next gripping materials, this process is synchronized. These two methods according to their own actual situation, the use of their own.
The study of robot needs to seriously consider a variety of factors, this course is a comprehensive course, involving the basic class of electrical professional courses, so you want to learn this course, the foundation is the key. For the above learning methods, involving the type of robotic training equipment, for general maintenance electrician certification using robots, this learning method can meet, but involves precise positioning of the type of material grasping, the need to use the encoder to record data, this method can be learned. We often use the FX2N series PLC, writing programs usually use two ways, one is the basic instructions to write the program; the other is to use the FX2N series PLC stepping instructions to write; both methods can be programmed on the manipulator, I recommend the use of the second method. This method is simple and practical, the idea is clearer, the program modular, easier to get started.
