摘　　要：架空输电线路杆塔工频接地电阻的测量方法采用三极法测量时,须放出两根探针及其连线,连线长度分别为2.5倍和4倍的接地射线长度。目前输电线路杆塔的接地射线最长约60 m,接地摇表测线总长约400 m,所携带的测线经常绞在一起,收放线工作量大,测线放出长度不准确,测量耗时长,测量结果不准确。文中以上述问题为切入点,深入分析导致问题的原因,并思考解决问题的工具及方式方法。Overhead transmission line tower grounding resistance of power frequency measurement method is divided into three pole method is used to measure,and its attachment must be released two probe,wire length,respectively 2.5 times and 4 times of grounding ray length.The transmission line tower grounding rays longest,about 60 meters,ground shaking table's line is about 400 meters,the line is often carried by twisted together,pay-off workload big,line release length is inaccurate and time-consuming measurement,the measurement result is inaccurate and to solve above problems as the breakthrough point,in-depth analysis of the causes of the problem,and think about the tools and methods to solve the problem.
