With the wide application of high voltage vacuum circuit breakers, failure is also common, and now the analysis of high voltage vacuum circuit breaker which are common abnormal operation and processing methods.
1 high voltage circuit breaker
Performance of the circuit breaker in the normal operating conditions, in the condition of unknown factors.
2 after the opening of the circuit breaker, the energy storage motor
Performance of circuit breaker in closing, operating organization of energy storage motor start operation, but the spring energy storage is full, the motor continues to work.
3 high voltage vacuum circuit breaker DC resistance increased
Performance of the circuit breaker in the work of a certain moment, the arc of the contact resistance of the contact resistance is increasing.
4 circuit breaker closing bounce time.
Performance for the circuit breaker in the work time, increasing the moment of closing bounce.
5 circuit breaker center box CT face bracket discharge
Performance of the circuit breaker in the work process, the current transformer table face center box bracket discharge.
6 circuit breaker arc extinguishing chamber can not be disconnected
Performance of high voltage vacuum circuit breaker in the operation of the division, the circuit breaker can not be broken open or non full phase disconnection.
