摘　　要：针对现有杆塔接地电阻检测方法普遍存在的检修效率低、操作流程复杂及人力成本高等局限性。本文提出一种基于钳表法的相位自同步式杆塔接地电阻测量方法,该方法通过创新性的设计,实现了免拆解、免布线的非侵入式测量、并且支持一键完成操作。仿真验证表明,相较于传统检测方法,该方法显著提升了现场工作效率的同时,误差控制在2%左右,为输电线路接地状态的高效评估提供了可推广的解决方案,具有较高的实用价值。For the traditonal detection method based on the transmission tower grounding resistance,such issues as the low maintenance efficiency,complex operational procedures,and high labor costs have to be solved.In this paper,a phase self⁃synchronization measurement method based on the clamp meter technique is proposed.By innovative design,the method can realize the non⁃invasive measurement without disassembly or wiring installation,as well as supports one⁃touch operation.Simulations validate the effectiveness of the proposed method by comparing with the conventional detection methods.It can significantly improve the on⁃site work efficiency with measurement error less than 2%,which provides a scalable solution for the efficient assessment of transmission line grounding conditions with practical value in power infrastructure maintenance.
