断路器弹簧储能异常信号情况分析及处理方案

Analysis of the signal "spring-stored energy is abnormal" of breaker and handling plan

紧水滩水力发电厂机组断路器弹簧储能操作机构常发"弹簧储能异常"信号,通过可编程控制器对信号处理的工作流程进行优化,分析了频发断路器弹簧储能异常信号的3种情况,提出了改善弹簧储能异常信号的处理方案。

The signal ＂spring-stored energy is abnormal＂ was given out frequently by the breaker spring storage operation mechanism in Jinshuitan Hydropower Plant. The three states indicated by the signal ＂ spring-stored energy is abnormal＂ were analyzed. The signal processing flow of programable logic controler（PLC） was optimized, and the handling plan for improving the signal ＂spring-stored energy is abnormal＂ was proposed.
