Transient Current Interruption Characteristics of a Novel Mechanical DC Circuit Breaker
IEEE Transactions on Power Electronics, 2018With the rapid development of multiterminal direct current (MTDC) grids, high-voltage direct current circuit breakers (HV-DCCB) capable of interrupting currents within 5 ms are in urgent demand. The mechanical DCCB has always been one of the main proposals for HV-DCCBs.

Contact Design of Arc Extinguishing Chamber in Virtual Platform of Mechanical DC Circuit Breaker
2020 5th Asia Conference on Power and Electrical Engineering (ACPEE), 2020The DC circuit breaker is used to realize fault isolation and clearing of the DC system, and is an essential core equipment for the DC distribution network. The principle of the mechanical DC circuit breaker is to generate the medium frequency oscillating current by LC and reversely inject into the main circuit to form a current zero crossing point ...
