| 摘 要： | 电网中性点采用经消弧线圈并电阻接地，可借电阻接地之长弥补消弧线圈接地之短，有效地抑制电弧接地过电压，使正常运行时的中性点位移电压不致过大。在这种接地方式下，利用计算机对消弧线圈进行控制，使其根据电网总电容电流的大小自动跟踪补偿，改变消弧线圈并电阻接地方式的不足

| Abstract: | The power network′s neutral point can suppress the arc-earthing over-voltage effectively when it is grounded through an arc-extinguishing coil.Further, if it is grounded through the arc-extinguishing coil of automatic tracking compensation(paralleling it with a resistance),it can overcome the defects of the above earthing mode,and canreduce the arc-earthing over-voltage to a lower value. |
