摘要
探讨高压内熔丝全膜并联电容器性能的提高问题,并与无熔丝电容器进行了对比,认为内熔丝的设计只满足于现有标准要求是不够的。为了优化熔丝设计,必须进一步研究内熔丝在严酷条件下的熔断过程,控制好限流特性并降低故障过电压。同时,文章还分析了无功补偿装置中电容器不恰当地配用喷逐式熔断器是导致群爆故障发生的主要原因。
The performance improvement of the Internally-fused HV capacitors and comparison with fuse-less capacitors is discussed in this paper. It is insufficient that the internal fuse design only satisfied the existing standard. In order to optimize the fuse design, the fusing process of the internal fuse under the critical condition must be studied further and its current limiting performance be controlled and over-voltage be reduced. The reason of multi-explosion failures in the operated reactive power compensation installations is due to improper provision of expulsion fuses.
