Abstract
Focusing on the problems of traditional forced commutation hybrid type DC circuit breaker like that there is large reverse recovery voltage when high-speed mechanical switches instantly open,and it is needed to add charging power supply to pre-charging capacitor,this paper proposed a new non-arc DC breaker topology based on once natural commutation and secondary forced commutation.The critical moment of the working stage was calculated though the equivalent mathematical model and the simulation was carried out to analysis the correctness of the derivation.The results show that the new DC breaker not only realizes the mechanical switch arc-less breaking,but also makes the breaking speed faster.关键词
