摘　　要：随着土地资源越来越紧张,变电站占地面积越来越小,在高土壤电阻率地区,变电站接地电阻设计到规定范围内的难度也越来越高。根据福建地区某高土壤电阻率地区110 kV变电站接地网设计,提出新型理念的斜井接地。With the increasing shortage of land resources,the substation occupies a smaller and smaller area.In the areas with high soil resistivity,it is more and more difficult for the grounding resistance of the substation to be designed within the specified range.In this paper,based on the grounding network design of a 110 kV substation in a high soil resistivity area in Fujian province,a novel concept of inclined shaft grounding was proposed to provide a new idea of grounding design.

关 键 词：变电站 高土壤电阻率 斜井接地
