摘要 针对民用建筑合建变电站受占地面积小等因素的限制,使用常规接地网设计方案难以满足接地系统的安全性与经济性要求,提出不等间距接地网结合斜长接地极的接地设计方案,经CDEGS软件仿真分析,接地电阻、接触电势和跨步电压均能满足校验要求。同时针对民用建筑合建变电站在分流系数、站外安全性等方面的特殊问题进行了分析。

Abstract：Concerned of the small occupied area of substation joined with civil building, ordinary earthing network design method is hard to satisfy the needs of safety and economy for earthing system. Unequal spacing earthing network combined with oblique-long electrode is applied. Earthing resistance, touch potential and step potential are all qualified after calculating by CDEGS. Special problems such as fault current division factor and safety outside substation are also considered in this paper.
Key words： substation joined with civil building    earthing system    unequal spacing    oblique-long electrode
