我国35kv 以下的高压电网大都采用中性点对地绝缘的中性点不接地系统。在这种电网发生单相接地故障时,为了及时处理,线路设有绝缘监测装置,一旦报警,值班人员与调度员应根据现象分析原因,按步骤查出故障点,保证正常供电。

High voltage power grid below 35kv in our country mostly adopts the neutral point grounding system of the neutral point to earth insulation . When single-phase earth faults occur in this grid , because the line is equipped with insulation monitoring device in order to timely solve these faults , the personnel on duty and the dispatcher will analyze the reasons according to the appearance and check the faults in right order to ensure the normal power supply .
