摘　　要：从城市配电网10kV中性点不同接地方式的优缺点、中性点接地设备的选择计算方法以及10kV中性点接地方式的选择原则等几个方面对城市配电网10kV中性点接地方式的关键技术进行了论述,并在此基础上提出了中性点经电阻接地方式零序电流保护的配置及整定计算原则。The key technologies of 10 kV neutral grounding city distribution network were discussed in this paper from the aspects of the characteristics of different grounding types, the calculation method for grounding equipment selection and the selection principle of grounding types. Based on these calculation principle of zero-sequence current protection in neutral resi discussions, th stance groundi e arrangement and coordination ng were proposed.
