摘　　要：在中性点不接地系统中,间歇性电弧过电压持续时间较长。若不采取措施控制,可能危及设备绝缘,甚至引起相间短路。本文将进行仿真计算,得出过电压数据,并提出相应的抑制措施。In ungrounded systems ,the duration of intermittency electric arc＇s earthing over-voltage is long.The insulation of electric equipments may be damaged if we do not take measures to control it, and furthermore, phase fault will appear.In this paper, simulations has been did to get dates of over-voltage and some preventive measures will be put forward.
