Analysis and Solution of the Abnormality of 500kV Circuit Breaker Anti-pumping Function

Through analyzing the abnormality of the 500kV circuit breakers anti-pumping circuit in 500kV Xiangshan substation, the coordination between the anti-pumping circuit in circuit breaker itself and the operating circuit inside control kiosk is described. A parasitic circuit in between circuit breaker and the kiosk is found and then solution method to this problem is worked out.
