| 摘 要： | 在中性点非有效接地系统中,为防止发生单相弧光接地引发的过电压造成设备事故,需要装设消弧线圈来补偿系统电容电流.通过测试系统电容电流,可以指导消弧线圈的正确投切.通过在现场进行测试比较,电容电流测试方法测试时间短、不接触高压、测试准确,并且不影响电网的安全可靠运行.

| Abstract: | In order to prevent single-phase ground from leading to arc grounding overvoltage which can cause equipment accident, So arc-extinguish coil need to be installed to compensate system capacitive current. System capacitive current testing can guide arc-extinguish coil correct switching. By test comparing on site, which has the advantage of short time, non-contact with voltage, test accuracy and no effect on electric network safe and reliable operation. |
