摘要
分析中压不接地系统采用电缆出线时电容电流的特点、对电缆的危害、对人身安全及系统设备选择的不利。提出可根据不同的电容电流采用中性点不接地运行和自动跟踪补偿消弧线圈残余电流的对策。
This paper analyzes the characteristics of capacitive current while cable outlet is used in mediumvoltage non-grounding system,its harm to cables and disadvantages to personal safety and selection of system equipments. And it is proposed to adopt neutral point non-grounding operation and automatic tracking and non-grouding residual current of arc-suppression coil according to different capacitive current.
