摘　　要：通过对一起220kV线路刀闸操作引起保护收发信机烧毁事故的调查,以及对现场实验拍录的干扰波形进行的频谱分析,初步了解刀闸操作电弧给附近设备造成的干扰量的幅频特性,并提出一些尚未解决的疑问。AbThrough the investigation of the bumtout of the transceiver caused by the operation of 220kV isolating switch, and by the spectrum analysis of the jamming wave recording on site,this paper primarily learns the amplitude--frequency characteristic of the interference which is caused by the arcing during operation of isolating switch and proposes some questions unsolved.
