摘　　要：导体交流电阻测试是电力系统运行和维护中的重要环节之一。随着电力系统的不断发展和电力负荷的增加,大截面导体的使用越来越普遍。然而,由于导体集肤效应和邻近效应的存在,导体在交流电流下的电阻会有所增加,这对电力系统的稳定运行和安全性产生了一定的影响。文章介绍了导体集肤效应和邻近效应的原理和影响因素,分析了影响交流电阻的因素,阐述了大截面导体交流电阻测试的各种方法,并对每种方法的原理、步骤和优劣进行了分析。Conductor AC resistance testing is one of the important links in the operation and maintenance of power systems.With the continuous development of the power system and the increase of power load,the use of large cross-section conductors is becoming increasingly common.However,due to the presence of conductor skin effect and proximity effect,the resistance of the conductor under alternating current will increase,which has a certain impact on the stable operation and safety of the power system.The article introduces the principles and influencing factors of conductor skin effect and proximity effect,analyzes the factors affecting AC resistance,elaborates on various methods for testing AC resistance of large cross-section conductors,and analyzes the principles,steps,and advantages and disadvantages of each method.
