Knowledge of explosion-proof motors: 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 and other faults, so what is the cause?How to deal with it?Next, the platform will explain to you:

Explosion-proof motor

1. There may be water or damp in the windings of the explosion-proof motor.The winding can be quickly dried by drying and heating.

2. Check that the windings of explosion-proof motor are covered with dust and oil. Generally, a small amount of dust and oil will not affect the normal operation of the motor.Can be cleaned winding grease, oil absorption paper for macerate treatment, if more dust can be used to wipe clean with a dry brush.

3. The winding board of the explosion-proof motor is damaged, and the lead wire insulation is aging or damaged.It is necessary to repackage the lead insulation. If the damage is serious, it is necessary to replace or repair the junction box and outlet box to ensure the safe and stable operation of the motor line.

4. The insulation of the explosion-proof motor is aged first, and the aging degree of the wire needs to be identified. If it can continue to be used, it needs to be cleaned and repainted for treatment.
