Investigations on the safe stroke of mechanical HVDC vacuum circuit breaker

Investigations on the safe stroke of mechanical HVDC vacuum circuit breaker

Here, a DC vacuum arc interruption test based on the hybrid high-speed actuator and the method of commutation is carried out in the synthetic loop system. The safe stroke is one of the basic breaking parameters. The minimum safe stroke directly determines the commutation time and breaking property o...
