Cause of frequent damage of power capacitors

Power capacitors in frequent damage is many enterprises. It's a headache. Only by correctly mastering the corresponding treatment methods and precautions for various common faults of capacitors can the service life of capacitors be extended, the chance of failure in operation be reduced, and the normal operation of the power system be achieved.

Types and causes of frequent damage to power capacitors:

1. Initial fault. Damage occurred shortly after power transmission, which was caused by poor manufacturing process and serious defects.

Coping strategy: Choose enterprises with strong registered capital background, such enterprises are more guaranteed in quality, have a complete system, and are good before and after sales; Choose to replace a good reputation, cost-effective power capacitor manufacturers;

2. An accidental fault occurs. During operation, the capacitor is damaged due to poor ventilation, external damage, operating overvoltage and lightning strike.

Coping strategies: improve the temperature environment of capacitors and keep the state of ventilation as far as possible; In order to prevent the damage of external factors such as lightning strikes and other accidents, it is necessary to install appropriate protection barriers (with protective covers) around the joint.

3. Wear fault. Due to insulation aging and internal ionization after many years of operation, the insulation strength is reduced and damaged.

Check and test the capacitor bank regularly, and replace the capacitor in time if the compensation effect is poor or bulge, leakage and other phenomena occur.

These are the reasons for the frequent damage of power capacitors, thank you for watching.
