The opening speed and closing speed of the VS1 vacuum circuit breaker should be explained as the average speed. These parameters are often found in the factory test report of the vacuum circuit breaker. So what is the opening speed and what is the closing speed? Gate speed, what impact does...
short-circuit current interruptionvacuum circuit breakerszero-voltage periodHigh resolution measurements on the post-arc current in vacuum circuit breakers reveal a period, immediately following current-zero, in which the voltage remains practically zero. The most widely used model for simulating the ...
3.3 Combined circuit breakers shall operate as follows: A. When opening, first break the circuit breaker, and then break off the touch knife, then the circuit breaker in the interlock device restrictions, can not be closed; B. When closing, you must first close the touch knife closing in ...
