1. The dust in the medium frequency power cabinet shall be removed regularly, especially for the core of the thyristor. Alcohol shall be used for dust removal of medium frequency power cabinet. Clean frequency conversion devices usually have a fixed special machine room, but the actual working environment in the smelting and forging process is not ideal, usually the dust and vibration in the working environment are relatively large. In the diathermy quenching process of Xi'an intermediate frequency power supply cabinet, the whole equipment is usually close to the acid pickling and phosphating equipment, there are more corrosive gases, usually These gases will cause great damage to the components of the equipment, and have a great impact on the insulation effect of Xi'an intermediate frequency power supply cabinet. If there is a lot of dust in the intermediate frequency power supply cabinet, it is easy to discharge the surface of the components, so we should pay attention to the cleaning work when maintaining the intermediate frequency power supply cabinet to reduce the occurrence of faults.

2. Regular maintenance shall be carried out for Xi'an intermediate frequency power supply cabinet. The main inspection contents include the inspection of the connection of bolts and nuts, the looseness of the contacts of fasteners and relays, and the poor contact. If any problem is found, it shall be repaired in time, and it shall not be used under the condition that the intermediate frequency power supply cabinet is faulty, so as to avoid major safety accidents.

3. The wiring of Xi'an intermediate frequency power cabinet shall be checked regularly to check the reliability of insulation.
