If the insulation resistance of the explosion-proof motor is too low, it will affect the normal operation of the explosion-proof motor, resulting in failure of the supporting equipment to operate normally. What is the cause? How to deal with it?
1. There may be water or moisture in the winding of the explosion-proof motor. It can be dried and heated to dry the windings quickly.
2. Check that the explosion-proof motor windings are covered with dust and grease. Generally, a small amount of dust and grease will not affect the normal operation of the motor. The winding grease can be cleaned, and the oil-absorbing paper can be used for impregnation. If there is a lot of dust, it can be wiped with a dry brush.
3. The winding board of the explosion-proof motor is damaged, and the insulation of the lead wire is aging or damaged. The lead wire insulation needs to be repackaged. If the damage is serious, the junction box and outlet box need to be replaced or repaired to ensure the safe and smooth operation of the motor wire.
4. The insulation of the explosion-proof motor ages first, and it is necessary to identify the aging degree of the wire. If it can continue to be used, it needs to be cleaned and repainted for processing. If the aging of the insulation wire will affect the safe operation of the explosion-proof motor, it needs to be replaced with a new one. insulated wire.
