消弧线圈限制过电压探讨

简述了中性点不接地系统在配电网规模增大、传输容量扩大、传输距离延长后，系统对地电容电流增大，故障时故障点形成的电孤不能自行熄灭，弧光过电压长时间加在系统的绝缘上危急设备安全，采用消弧线圈限制过电压的措施。

Using arc suppression coil to limit arc grounding overvoltage and ferroresonance overvoltage

With the expanding of distribution network, transmission capacity and transmission distance, the ground capacitive current increases rapidly in ungrounded current at the fault point can not be extinguished and arc This paper proposes that adoption of arc systems. The electric arc of grounding capacitive grounding overvoltage will expand the accident. suppression coil to limit the overvoltage.
