【摘要】 提出了配电系统中性点经非线性电阻接地的构想．经对基本接线的分析与计算，结果表明，这种接地方式不仅可以很好地限制电力系统中的过电压，而且基本保留了中性点直接接地与中性点不接地两种方式的优点．同时对非线性电阻的热容量的要求较之线性电阻的热容量的要求低得多．更多还原

【Abstract】 This paper presents the idea of neutral grounding through nonlinear resistancc in thc distribution system. Through analysis and calculatiort of basic configuration, the results show that this kind of ncutral grounding not only can limit thc overvoltage, but also mainly preservc the advantagc of ncutral dfrect grounding and non-grounding system. Meanwhile the thermal capacity of nonlincar resistance is much lcss than that or lincar rcsistance..更多还原
