The price of transformer winding machine ranges from hundreds of thousands of yuan to tens of millions of yuan, which is generally the key equipment of key products and key processes in the enterprise, and the impact and loss are often great once the fault is shut down. However, people often pay more attention to the efficiency of the transformer winding machine, and not only pay enough attention to the reasonable use, but also pay too little attention to its maintenance and repair work, and do not pay attention to the creation and investment of maintenance and repair working conditions, the phenomenon of failure is very common. Therefore, in order to give full play to the benefits of the transformer winding machine, we must pay attention to maintenance work and create good maintenance conditions. Because the daily occurrence of transformer winding machine is mostly electrical faults, electrical maintenance is more important.

1. Personnel conditions

The rapidity and good quality of transformer winding mechanical and electrical maintenance work depend on the quality of electrical maintenance personnel.

(1) First have a high sense of responsibility and good professional ethics.

(2) A wide range of knowledge. It is necessary to learn and basically master the knowledge of various disciplines related to transformer winding electrical and gas control, such as computer technology, analog and digital circuit technology, automatic control and drag theory, control technology, processing technology and mechanical transmission technology, of course, including the basic numerical control knowledge mentioned in the previous section.

(3) Master a foreign language, especially English. At least be able to read technical data.

(4) Dare to practice. It is necessary to actively invest in the maintenance and operation of CNC machine tools, and improve the analytical ability and practical ability in continuous practice.

(5) should have good technical training. The learning of the basic theory of transformer winding machine technology, especially for the specific technical training of transformer winding machine, first participate in relevant training courses and practical training on the installation site of transformer winding machine, and then learn from experienced maintenance personnel, and more important and longer is self-study.

(6) Master the scientific method. To do a good job of maintenance, enthusiasm is not enough, but also need to sum up and improve in long-term study and practice, from which to extract scientific methods to analyze and solve problems.

(7) Learn and master various instruments, meters and tools commonly used in electrical maintenance.

2. Material conditions

(1) Prepare general and special electrical spare parts for a transformer winding machine.

(2) The use and maintenance of transformer winding machine technical file materials.

(3) Necessary maintenance tools, instruments, etc., as far as possible with a laptop computer and equipped with the necessary maintenance software.

(4) Complete technical drawings and data for each transformer winding machine.

(5) Non-essential standing electrical components should be fast and smooth procurement channels.

3. About preventive maintenance

The purpose of preventive maintenance is to reduce the failure rate, and its work mainly includes the following aspects of work.

(1) Personnel arrangements for each transformer winding machine assigned special operators, technicians and maintenance personnel, all personnel must constantly strive to improve their business technology level.

(2) Improve the utilization of transformer winding machine if idle for a long time, when it needs to be used, the first movement of the transformer winding machine will affect its static and dynamic transmission performance due to oil solidification, dust and even rust, reduce the accuracy of the machine tool, the blockage of the oil system is a big nuisance; From the electrical point of view, because the entire electrical control system hardware of a transformer winding machine is composed of tens of thousands of electronic components, their performance and life have great discretization, from the macro point of view, there are three stages: in a year basically in the so-called "run-in" stage. At this stage, the failure rate shows a downward trend, and if the transformer winding machine is continuously started during this period, the "running-in" task will be completed faster, and the one-year maintenance period can be fully utilized; The second stage is the effective life stage, that is, the stage of full performance. Under the conditions of reasonable use and good daily maintenance, the transformer winding machine can operate normally for at least five years; The third stage is the aging stage of system life, electrical hardware failures will gradually increase, and the average service life of the transformer winding machine is about 8 to 10 years.

(3) Daily maintenance For each transformer winding machine should establish a daily maintenance plan, including maintenance content (such as lubrication of the axis transmission system, wear conditions, spindle lubrication, etc., oil, water and gas road, temperature control, balance system, cooling system, tightness of the transmission belt, relay, contactor contact cleaning, whether the plugs and terminals are loose, Ventilation of electric cabinet, etc.) and the maintenance cycle of various functional components and vital parts (daily, monthly, half-year or irregular).

(4) For the specific performance of each transformer winding machine and processing objects to develop operational regulations, establish work and maintenance files, managers should often check, summarize, and improve.

Therefore, in the absence of a processing task for a period of time, try to run the machine tool at a low speed, at least often to power the CNC system, and even every day should be powered on.
