摘　　要：通过分析SF6电流互感器在出现故障时的现象统计,能发现大部分情况下SF6电流互感器异常多发生在夜间,而在白天恢复。之所以会出现这样的问题是因为SF6电流互感器本身所需要承担的负荷有着非常明显的关系,本文主要针对互感器出现问题进行简要分析。By analyzing the phenomenon statistics of SF6 current transformer in the event of failure,it can be found that in most cases SF6 the abnormal current transformer occurs at night and recovers during the day.Because of the obvious relationship SF6 the load of the current transformer itself,this paper mainly analyzes the problems of the transformer.
