摘　　要：目前,杆塔接地电阻测量时需要解开接地引下线,现场的引下线连接方式使得解线工作难以实施,为了提高输电线路杆塔接地电阻测量、检修时的工作效率,提出了一种免解线高频测量的新方法。该方法基于物联网技术可实现数据和信号源的无线传输,使得测量过程便捷、准确。理论计算和实测结果均表明,该方法能在不解开接地引下线的前提下,实现对杆塔接地电阻快速准确的测量。At present,when measuring the grounding resistance of towers,it is necessary to untie the grounding connecting cable.However,it is difficult to carry out the work of the line solution due to the connection mode of grounding cable in the field.A novel method of high frequency measurement on the free solution line is proposed,to improve the efficiency of measuring and repairing for the grounding resistance on transmission line tower.The method is based on the technology of Internet of things,achieving the wireless transmits for data and signal sources.Both the theoretical calculation and the measured results show that,it is quick and accurate for the method to measure the ground resistance of the tower without untying the grounding wire.
