| 摘 要： | 针对10kV中性点不接地系统的特点,介绍运行中的电磁式电压互感器高压侧熔丝熔断,详细分析了产生故障的原因,分析表明系统在单相接地时或接地故障消失后都可能会产生过电流,系统装设消弧线圈或采用零序电压互感器接线方式都能较好地抑制此过电流。

| Abstract: | For 10kV ungrounded system features,the electromagnetic voltage transformer high side fuse to melt in operation is introduced,the causes are analyzed in detail.Analysis shows that the system in or after single-phase grounding fault is likely to produce over-current,and the installation of arc-suppression coil or using a zero-sequence voltage transformer wiring can better suppress the over-current. |
