集合式高压内熔丝电容器的一种特殊故障形式及运行中应注意的问题

Special Fault and Problems in Operation for HV Capacitor with Internal Fuse

集合式高压内熔丝电容器在运行中常常会出现突然跳闸,而当检查时又无问题的现象,这给现场运行人员带来很大的困惑。文章对此特殊故障形式进行了原因分析,并提出了检测方法(如测量单台电容器的电容量)及应注意的问题,以提高集合式内熔丝电容器的运行可靠性。

HV capacitor with internal fuse （assemble type） in operation can often appear suddenly tripping without the phenomenon of problem, which is greatly perplexed to the operation people on-the-spot. The paper analyzed the reason for this special fault, and put forward the detection method and the problems should he noticed, in order to improve the operation reliability of HV capacitor with internal fuse, and let operation people refer to.
