| 摘 要： | 对于中性点不接地的电力系统，在发生单相接地时，接地电流决定于另两相电容电流。如果系统地对电容较大，电弧不易熄灭，从而产生弧光接地过电压，造成停电和设备损坏等事故。因此，我们需要对系统电容进行测量，利用消弧线圈进行合理的补偿，以提高供电的可靠性。

| Abstract: | In the case of neutral-point-unearthed electric power system,earthed current depends on another two phases of condenser current when monophase ground connection takes place. If capacitance go ground is rather large,arc is not easy to go out,thas generating overvoltage because of arc light ground connection and causing power cut and damage to equipment. Therefore,it's necessary to measure the capacity of the system and use arc suppressing coil to make rational compensation so as to reinforce the reliability of power suply. |
