摘要
Abstract
The 6~35 kV power supply and distribution system of metallurgical enterpris-es generally adopts ungrounded mood at the neutral point. With the expansion of power grid and increase of cable outlets, the earth capacity and earth current of the system have in-creased dramatically, so if overvoltage happens in the system it is easy to cause major acci-dent of short circuit between phases. Therefore, the 6~35 kV power systems mostly adopt arc suppression ark to limit overvoltage in power grid and improve the safety of power grid opera-tion and reliability of power supply.关键词
