摘　　要：介绍了某海外500 kV变电站发生的一起33 kV滤波电抗器故障,通过分析得出该电抗器故障原因为结构设计不合理,不能满足系统耐受短路电流要求。针对此次故障提出了解决方案,对滤波电抗器的耐受短路电流能力设计有一定参考价值。This paper introduces the fault of a 33 kV filter reactor in a 500 kV substation.It is concluded through analysis that the fault reason of the reactor is unreasonable structure design.So it cannot meet the requirement of the system to withstand short circuit current.A solution is proposed for this fault,which is of some reference value to the design of short-circuit current tolerance ability of the filter reactor.
