摘要
介绍了一起高压限流熔断器非正常开断的事故过程,分析了其未能有效开断的原因,并提出了避免高压限流熔断器不能有效开断的方法。一是熔断器选型时要考虑修正系数,二是要改善系统参数,防止发生操作过电压和减少谐振过电压的发生概率。
This article introduces the process of high-voltage current-limiting fuse abnormal breaking, analyzes the reason of failure to effective breaking, and puts forward the methods to avoid ineffective breaking. First, the modified coefficients should be considered during the fuse choosing. The second, parameters of system should be improved to prevent operating overvoltage and reduce the probability of resonance overvoltage.
