Explosion-proof motor knowledge: What is the cause of low insulation resistance? How to deal with it?
The low insulation resistance of the explosive motor will affect the normal operation of the explosion-proof motor, resulting in the failure of the supporting equipment to operate normally, so what is the cause? How to deal with it? Next, the platform will explain:
Explosion-proof machine
1. It may be that the windings of the explosion-proof motor are flooded or damp. It can be dried and heated to dry the winding quickly.
2. Check the dust and grease of the explosion-proof motor winding, generally a small amount of dust and grease will not affect the normal operation of the motor. The winding grease can be cleaned, impregnated with oil-absorbing paper, and cleaned with a dry brush if there is too much dust.
3. The winding plate of the explosion-proof motor is damaged, and the insulation of the lead line is aging or damaged. It is necessary to re-wrap the lead insulation, and if the damage is more serious, the junction box and the outlet box need to be replaced or repaired to ensure the safe and smooth operation of the motor line.
(4) The insulation of the explosion-proof motor aging first, need to identify the aging degree of the line, if you can continue to use it needs to be cleaned and repainted
