Development of HVDC Circuit Breaker and its Interrupting Test
IEEE Transactions on Power Apparatus and Systems, 1982The authors have developed a DC circuit breaker (DCCB) which interrupts a DC current by injecting a high-frequency reverse current from a commutating capacitor to be superposed to DC current and forcibly creating a current zero point. A breaking part consists of a vacuum interrupters or a SF6 gas, interrupters of the most advanced design connected in ...
