与高压输电系统临近的通信局(站)地电位的分布

The Distribution of Ground Potential in the Earth-electrode Netwok of Communication Bureau Close to High-voltage Transmission System

论述了中性点直接接地高压输电系统发生接地故障时,其附近的通信局(站)地网上的地电位分布,根据不同的接地故障位置选择相应的模型推导出相应的地电位升公式,同时给出了案例分析。

This paper discusses the situation when Ground fault occurs in Neutral Grounding high-voltage transmission system, how do the ground potential in the earth-electrode netwok of communication bureau close to the location of the ground fault is distrib-uted. Depending on the location of the ground fault, the appropriate model is selected, the corresponding formula is derived and at the same time one case study is given.
