Abstract: Analysis was made to the abnormal switch position indication of 10kV internal leakage drainage pump in Jinping two stage hydropower station and the problem that the circuit breaker couldn’t be closed again later on. By comparing Nari protection anti-jump circuit switch with Schneider body anti-jump circuit which the circuit breaker configured, the application ranges for protection anti-jump circuit and body anti-jump circuit were obtained. This paper proposed four kinds of improved anti-jump circuit-breaker circuits and compared each advantage.
           Key words: circuit breaker; anti-jump circuit of protection; anti-jump circuit of circuit breaker
