High voltage motor housing is the main reason and treatment to understand it ~ high voltage motor can be used to drive a variety of different mechanical use, so its scope of application is relatively wide, such as water pump, crusher, generator, petrochemical industry and other industries have used it. So today, Lanhai electromechanical will explain to you the main reason and treatment of high voltage motor housing electrification, I hope to help you in the future use.

　　The insulation of lead wire or junction box joint is damaged and hits the ground. After inspection, cover with insulating sleeve or wrap insulating cloth.

　　The end is too long to touch the housing. The grounding phenomenon is eliminated after the end cover is removed. At this time, the winding end should be brushed with a layer of insulation paint, and pad insulation paper and then installed on the end cover.

　　Groove at both ends of the notch insulation damage, carefully pull the winding end part, patience to find out the insulation damage, and then put the insulation paper coated with insulation paint.

　　There are iron chips and other sundries in the groove that have not been removed. Remove iron scraps and other sundries.

　　There is mechanical damage to conductor insulation during wire insertion. Carefully pull winding end joint, patience to find out the insulation damage, and then put on insulation paper and coated with insulation paint.

　　The enclosure is not reliably grounded. After troubleshooting according to the above methods, the motor housing shall be reliably grounded.
