断路器防跳回路的分析与优化

Analysis and Optimization of Anti-bouncing Circuits for Circuit Breakers

阐述了操作箱防跳回路和断路器机构防跳回路的工作原理,探讨了操作箱防跳与断路器机构防跳的区别。针对一起断路器防跳回路元件参数失配案例进行探讨,提出了在防跳回路中串接电阻、串接断路器分位辅助接点等改进措施来优化防跳回路,防止断路器在短时间内多次分闸、合闸,为电力系统的安全可靠运行提供更加坚实的保障。

The working principles of operation box anti-bouncing circuit and circuit breaker mechanism anti-bouncing circuit are elucidated.The differences between operation box anti-bouncing circuit and circuit breaker mechanism anti-bouncing circuit are analyzed.A case of mismatch of anti-bouncing circuit component parameters is discussed,and the improvement measures are proposed to optimize the anti-bouncing circuit,such as series connection of resistor and series connection of open position auxiliary contact of circuit breaker in the anti-bouncing circuit,which prevent multiple opening and closing of circuit breaker in a short period of time and provide a more solid guarantee for the safe and reliable operation of power system.
