摘要
针对高土壤电阻率地区变电站接地网的接地电阻很难满足规程要求的问题，通过对土壤结构及土壤电阻率和接地电阻定义及影响因素的分析，探讨高土壤电阻率地区变电站降低接地电阻的方法，并提出降低接地电阻注意的问题。
In this paper, directing at grounding resistance of grounding system in substation is ditffeult to meet the requirements of order in high soil resistivity regions, soil structure, soil resistivity, the definition of grounding resistance and its influencing factors are analyzed. The way of reducing grounding resistance in substation of high soil resistivity regions is diseussioned, and the attention in reducing grounding resistance is put forward.
