Traditional electrical engineering is defined as the sum of related disciplines used to create electrical and electronic systems. This definition was very broad, but with the rapid development of science and technology, the concept of electrical engineering in the 21st century has far exceeded the scope of the above definition. Stanford University professors point out that today's electrical engineering covers almost all engineering activities related to electronics and photons.
How to check the failure of Shenyang Electrical Engineering Equipment?
1. Investigation: Ask the operator and the person who has the problem, including the external performance of the problem, the approximate location, and the environmental condition at the time of the problem. If there is no abnormal gas, open flame, whether the heat source is close to the power equipment, whether there is corrosive gas intrusion, whether there is water leakage, if anyone has performed maintenance, what is the maintenance content and so on.
2. Preliminary inspection: According to the investigation, the manufacturer of Shenyang Motor checked whether the external power supply was damaged, whether the wiring was disconnected or loose, whether the insulation was burnt, whether the fuse indicator of the spiral fuse jumped out, and whether the power supply had water or grease. Is the switch position correct?
3. After the initial test, confirm that it will further expand the fault and cause personal and equipment accidents, and then you can further test. During the test, please note if there are severe flashovers, odors, abnormal sounds, etc., and stop immediately after discovery. cut the power supply. After installing the power supply, please check whether the installation temperature of the power supply and the operation steps of the power supply meet the requirements of the diagram to find the cause of the fault.
