提供两点建议来保证真空断路器的正常运行

2013/11/20 12:53:29      点击:
      如果想要保证断路器的正常工作,必须采取对其运行分析做出总结,在故障发生之前就可以很快速准确的排除安全隐患,下面给大家两条参考意见,可以根据实际情况采取相关的方案措施。
 1、全面完成上级下达的反措计划
  反事故措施是根据运行中曾出现的设备异常、故障及事故,结合系统实际情况,采取的防止设备故障重复出现的有效措施。
 2、加强备品备件的购置及管理
  双河变电站有部分缺陷因无备品长期得不到处理,在断路器方面也存在这一现象,如双22开关计数器不动、部分并联电容器介损超标仍在运行,这给安全运行留下隐患,也使双河变电站的消缺率得不到提高。

      双河变电站断路器反措情况总的执行情况是好的,但也有少数项目未执行或未坚持,如断路器进行低电压跳合闸试验,双河变电站也一直未执行,在直流系统异常的情况下,断路器能否正确动作未得到检验;如少油断路器油务监测,未按有关规程要求定期(一年一次)进行,断路器是否受潮不能很好地监视;再如辅助接点的检修,要求结合小修时进行,但也未坚持,实际是一般在大修时才对辅助接点检修,双河变电站在几次断路器“控制回路断线”故障处理中,发现220KV少油断路器辅助接点污垢极其严重,造成辅助接点接触不良。
