Abstract

To reveal the optimal arcing time of a 40.5 kV double-break vacuum circuit breaker during capacitive interruption when two breaks function non-simultaneously

the voltage distribution characteristics between the two breaks during capacitive interruption were briefly discussed

and the mathematical expression of over-voltage was derived. The values of over-voltage between two breaks in different arcing time were calculated. And a laboratory test was performed on a real 40.5 kV double-break vacuum circuit breaker to verify its re-ignition characteristics during capacitive interruption. As a result

based on the theoretical and test results obtained in this study

the optimal arcing time of the 40.5 kV double-break vacuum circuit breaker with permanent magnet actuator during capacitive interruption is suggested.
