Key points of electrical equipment maintenance and overhaul technology

Abstract: the maintenance and overhaul of electrical equipment is an important way for enterprises to reduce operating costs, which fundamentally extends the service life of electrical equipment and delays the replacement of old and new equipment. The first 311 exterior wall internal insulation board is a prerequisite for enterprises to have the relevant technology of electrical equipment maintenance and overhaul. Cultivating talents with high-level skills is a prerequisite, so that they can be handy in the face of many electrical faults

before overhauling the corresponding electrical equipment, it is necessary to do a good job in data investigation and research to ensure that the first-hand data of the fault are mastered and analyzed. When diagnosing electrical equipment faults, first of all, you can carry out maintenance work by watching the fault phenomenon on the surface of the equipment. Secondly, generally, there will be scorched parts in electrical faults. Maintenance personnel can identify the fault by smelling. Now the matching problem of the fuselage vibration alarm circuit of the reciprocating unit is analyzed. Again, the maintenance personnel know the state or situation before and after the equipment failure by asking the operator

2. Use logical thinking to analyze the scope of failure

through the investigation and research before maintenance, we will eventually develop good materials that are technologically advanced and fully meet the needs of customers. Maintenance personnel should ensure that their minds are clear, and determine the scope of failure and the location of the failure according to the investigation results and previous experience. If the scope of the fault is the main circuit, this kind of situation is relatively simple, and the problem can be found directly by checking

3. Reduce the fault scope through the test and detection of the equipment

after the test of the main circuit and the high-strength circuit of the control electricity (1), the corresponding fault point is still not found. In such cases, only the next step of detection can be carried out to reduce the fault scope. Usually, the test and detection of the equipment are used. Test and inspection refers to energizing the electrical equipment load and removing the load, and comparing the current operation state with the daily operation state, so as to determine whether it is an operational fault, external component fault, internal fault of the equipment or other mechanical fault. The premise of adopting the test and detection method is not to expand the fault scope and damage the equipment

4. This method of using instruments to detect electrical equipment faults is called resistance method. The measuring tool used is the ohm gear of the multimeter. The principle is to judge the fault point of the equipment by measuring the resistance to ground of the integrated circuit, transistor and other components in the internal structure of the electrical equipment. Instrument measurement method is a common detection method at present, which has the characteristics of accurately locating the point of failure

the maintenance and overhaul of electrical equipment is an important way for enterprises to reduce operating costs, which fundamentally extends the service life of electrical equipment and delays the replacement of old and new equipment. The premise of all this is that the enterprise must have the relevant technology of electrical equipment maintenance and overhaul, and cultivating talents with high-level skills is a prerequisite. In this way, when facing many electrical faults, it can be handy, so that the development of the enterprise can be guaranteed
