摘要
在电力系统中我国电网的运行方式是110k V及以上的电网通过采取直接接地运行方式,而在110k V以下的经常有中性点不接地或经过消弧线圈和高阻抗接地方式,后者一般称作小电流接地系统。但出现接地短路的概况比较多,文章即对出现小接电流接地系统进行研究分析。
In the power system, the operation mode of the power grid in China is llOkV and above by adopting the direct grounding mode, while those below llOkV often have the neutral point ungrounded or through arc-suppression coil and high impedance grounding mode. The latter is commonly referred to as a small current grounding system. However, there are many cases of earthing short circuit. In this paper, the grounding system with small connection eurl＇ent is studied and analyzed.
