| 摘 要： | 中压电网的中性点接地方式以往多为不接地或经消弧线圈接地，当电容电流大到一定程度后应向电阻接地方式转换，以提高电网运行的安全可靠性。上海宝钢集团一钢公司35kV系统正在进行这种转换。

| Abstract: | The neutral point earthing modes of medium-voltage electric netwo rk usually use unearthing or earthing through arc extinction coils. When the cap acity current is large enough, the neutral point earthing mode of the electric n etwork should change to the resistance earthing mode so as to increase safety re liability of the electric network operation. The 35 kV system of No.1 Steel Divi sion of Shanghai Baosteel Group Co. is carrying out the changing. |
