摘　　要：接地网是维护变电站安全、可靠运行的根本保证和重要措施。文章阐述了变电站土壤电阻率偏高、无具体勘探测量、测量值不可信、讯息工期不细致等接地网电阻偏高的原因，提出了引外接地、深井接地、放置电角电极、换地等降低接地电阻的主要措施。The grounding grid is the basic guarantee and an important measure to maintain safe and reliable operation of substations. This thesis expounded the causes for the high resistance of substation grounding grids and presented the main measures to reduce grounding resistance.
