Tips: How to Maintenance Vacuum Circuit Breaker?

  • Insulation.

This is one of the simplest maintenance techniques. Insulation maintenance applies to the cleaning of all the insulation surfaces. Any soft cloth, such as dry lint-free cloth or dry paper towel can be used to wipe the dust off from the insulation surfaces to ensure it smooth operation.

If wiping is unable to remove dust well, distilled water or a mild solvent can be used to remove. Once wiped, make sure that all the surfaces have completely dried up before placing the circuit breaker into use.

  • Lubrication.

Proper lubrication is required periodically to ensure the overall smooth and correct operation of all the components of a vacuum circuit breaker and VCB maintenance. The gap between relubrication depends on the frequency of the circuit breaker used.

For lubrication, a drop of light machine oil can be used. After lubrication, the circuit breaker needs to be operated several times manually and electrically so that the oil is absorbed into the parts.
