Timetric Indoor Medium Voltage Fixed Vacuum Circuit Breaker Product maintenance:

Normally transported circuit breakers should be maintained regularly to remove the dust on the surface of the insulating parts, and the vacuum degree of the Indoor Medium Voltage Fixed Vacuum Circuit Breaker extinguisher chamber should be checked by the power frequency voltage resistance method. Users should not arbitrarily change the use of electrical components inconsistent with the original model. Operators should have a preliminary understanding of circuit breaker performance and basic knowledge of installation, adjustment and maintenance, record the problems in operation, notify the manufacturer if necessary, and send personnel to help solve the problems.
