摘要
对配电系统几种主要的接地方式从理论和实际运行两方面进行了详细分析,指出了各种方式存在的问题,并讨论了影响其选择的因素.指出必须根据电网实际情况,因地制宜,综合考虑,合理选择中性点接地方式.对电容电流小的配电网仍可采用不接地方式,对电容电流较大、架空线路为主的配电网应选择自动跟踪消弧线圈接地方式,对电缆为主的配电网,中性点经电阻接地是优先选择的方式.
The paper .analyzes several grounding methods of the power distribution system from theories to practical operation and discusses several influencing factors. It points out that we should choose in reason neutral grounding model according to the power actual circumstance and synthesis consideration. For small capacitance current power, we can still adopt Neutral point non-grounding model. For larger capacitance current and overhead wire power, we should choose automation tracking grounding by arc - suppression coil. And for electric cable power, Neutral point grounding by resistance is a prior model.
