Abstract：Circuit Breakers do "anti-jump" test , after closing pulse signal is removed, the anti-hop relay can not be reset, the circuit breaker can not perform electrical closing operation, Aiming at this phenomenon conducted in-depth research, and most of the literature presented in the Tab series circuit monitoring anti-hop relay normally closed auxiliary contact is verified, pointed out the shortcomings of the program, proposed amendments closing operation circuit board, opening moni-toring circuit breaker series NC auxiliary contacts rehabilitation programs, which enable rehabilitation programs op-erating circuit breaker anti-jump to adapt to different domestic manufacturers of protective devices, measures and the proposed transformation specification VS1 circuit board design can be used as domestic breaker designers reference.
