| Abstract: | This paper analyses the reason why the tripping and closing coil of circuit breaker tends to being burnt down,and a practical and feasible scheme is proposed based on the thorough research of domestic and foreign circuit breaker control loops.It has been proved by practice that the tripping and closing coil of circuit breaker can be protected by taking this scheme.Besides,second tripping and closing operation and fault data recording and exporting are realized. |
