On-line Detecting Vacuity of Interrupter of Vacuum Circuit Breaker

摘要

In this paper, the discharge between the vacuity of interrupter of vacuum circuit breaker and electric potential of shield when vacuum circuit breaker is running is discussed. The pulses of electromagnetic wave caused by discharge are related to vacuity of interrupter of vacuum circuit breaker. The vacuity is found out by the relation. The method based on this principle that the vacuity is found out by the instrument detecting pulses of electromagnetic waves are proposed in order to vacuum circuit breaker on-line is monitoring.
