一种配电网中性点智能电阻接地方式的人身安全处理法
摘要：
本发明为一种配电网中性点智能电阻接地方式的人身安全处理法，在配电网采用中电阻接地方式对单相接地故障进行处理时，根据电网中性点位移电压UN的大小把配电网单相接地故障划分为不同的接地故障区并采用不同的处理方式以满足不同的需要。当配电网发生单相断线接地故障戓人身触电等高阻故障时能准确选出并切除故障线路，确保设备和人身安全。
摘要（英）：

The present invention provides a personal safety processing method of a neutral point of an intelligent resistance grounding mode in a power distribution network. When single-phase grounding faults are processed in a resistance grounding mode in the power distribution network, the single-phase grounding faults are divided to different grounding fault regions according to the sizes of displacementvoltages of neutral points in the power distribution network, and different processing modes are employed to meet different requirements. When the high-resistance faults of the power distribution network such as single-phase breakage grounding faults or personal electric shock are generated, the personal safety processing method provided by the invention can accurately select and cut off fault circuits to ensure device and personal safety.
