摘要:
介绍了熔断器的安秒特性,以河南某110 kV变电站为例,分析了无功补偿电容器的熔断器群爆的主要原因,一是参数选择不当,熔断器的额定电流选得偏小,电容器的额定电压选得偏低,单只电容器的容量选得偏大；二是继电保护配置方面存在问题,电容器的过电压保护没有起到作用.通过调整熔断器和电容器的参数,并加装电容器零序过电压保护,使得整改后的补偿装置运行稳定.
Abstract:
This paper introduces the ampere-second characteristics of fuses and takes the case of an 110kvsubstation in Henan province to analvze the main reasons of its multi-fuse failure: one is improper parametersincluding small rated current of fuses , low rated voltage of capacitors and big capacity of individual capacitors ;the other is the problem of the relaying protection configuration that the overvoltage protection of capacitorsdoes not function properly, With parameters of fuses and capacitors adjusted and zero sequence overvoltageprotection devices for capacitors installed, improved compensation device has not had any multi-fuse failure inoperation so far.
