摘　　要：中性点接地方式的正确选择及其在不同条件下的实施具有十分重要的工程意义,是电力系统实现安全与经济运行的技术基础,尤其在配电网中,常常采用中性点经消弧线圈接地或者经小电阻接地,而选择中性点经小电阻接地的适用性还有待完善。课题对10 kV配电网中性点经小电阻接地的方式进行研究,探讨配网中性点采用经小电阻接地方式的适用条件,研究结果对中性点经小电阻接地方式的应用具有理论指导意义和工程实用价值,对电力系统的安全稳定运行具有重要意义。The correct selection of neutral grounding mode is the technical basis for the safe and economic operation of power system,and its implementation under different conditions is of great engineering significance.In distribution network,neutral point is usually grounded through arc suppression coil or small resistance.The applicability of neutral grounding through small resistance needs to be improved.This paper studies the way of 10 kV distribution network neutral grounding through small resistance,and discusses the applicable conditions of the way of distribution network neutral grounding through small resistance.The research results have theoretical guiding significance and engineering practical value for the application of neutral grounding through small resistance,and have important significance for the safe and stable operation of power system.
