Abstract :
A newly developed d.c. circuit breaker successfully interrupts the current up to 130 kA d.c. under 44 kV d.c. recovery voltage. The breaker also can carry out the respective 4000 times operations of the above breaking duty every ten minutes without any trouble. The essential breaking mechanism is composed of two series and four parallel construction of vacuum valves with current commutation capacitor.
