断路器两套防跳回路配合问题探讨

摘要

Through analyzing the abnormality of the 220 kV circuit breakers anti-pumping circuit in 220 kV substation of Weihai electric power plant, the coordination between the anti-pumping circuit in circuit breaker itself and the anti- pumping circuit inside control kiosk is described. A parasitic circuit in between circuit breaker and the kiosk is found then solution method to this problem is worked out.%通过对威海电厂220kV升压站220kV断路器防跳回路出现故障现象进行分析，阐述开关本体防跳回路和装置操作箱防跳回路的配合，揭示断路器本体防跳回路与装置操作箱防跳回路之间存在的寄生回路问题，并提出解决技术方案。
