摘　　要：在3～35kV中性点不接地系统中,需采取消弧措施以保证系统安全运行,除了采用消弧线圈外,还出现一些新型的消弧消谐及过电压保护装置。对在故障相投入0.75UN(相电压)氧化锌接地进行消弧的方法进行了论证。Are suppression measures should be taken to guarantee the safe running in the 3-35KV isolated neutral system. Besides petersen coil, there are some new type are suppression equipment and overvoltage protection. The means of are suppression by fault phase grounding with ZnO in phase voltage is proved.
