10-kV/15-kA强迫谐振式直流断路器的综合建模、优化与实验

The dc circuit breaker (DCCB) is the core equipment for ensuring the safe and stable operation of the dc transmission system. It often requires high response times. In recent years, a new type of DCCB topology called forced resonant DCCB (FR-DCCB) has attracted widespread attention. It requires only a small amount of power electronic devices to provide mechanical switch zero crossing with LC circu...
