10 kV系统接地运行方式现状分析

Analysis on the Status Quo of Grounding Operation Mode of 10 kV System

近两年10 kV系统中性点接地方式改造工作不断推进,目前揭阳电网范围内出现了10 kV系统多种中性点接地方式并存的情况,文章对几种最常见的的接地方式应用的现状进行分析,着重介绍了经小电阻接地的运行特征及防止保护误动的注意事项。

In the past two years,the transformation of the neutral grounding method of the 10 kV system has been continuously promoted.At present,there are multiple neutral grounding methods of the 10 kV system in the Jieyang power grid.The current situation of the application of several most common grounding methods The analysis is carried out,focusing on the operating characteristics of grounding via a small resistance and the precautions to prevent the protection from malfunctioning.
