摘要

研究了中性点经小电阻接地方式对弧光接地过电压的影响。首先理论分析了弧光接地过电压在中性点经小电阻接地系统中存在的可能性

并用EMTP对其进行了过电压计算。研究表明

中性点经小电阻接地方式有效地解决了弧光接地过电压问题

Abstract

In this paper

theoretical analysis is made firstly about the possibility of arc-grounding overvoltage existing in low-resistance grounding system. Calculations on overvoltage magnitude are performed by EMTP. The results show that the problem of arc-grounding overvoltage is settled effectively with low-resistance grounding method.
