摘　　要：本文是部分感应电压系数概念的应用。通过计算与正馈线位置相关的部分感应电压系数λs,讨论正馈线位置对通信线上感应电压的影响。分析表明 ,当通信线与铁路的距离小于 4 5m时 ,正馈线位于支柱外侧较好 ;而当通信线与铁路的距离大于 4 5m时 ,正馈线位于支柱内侧好。The paper introduces application of the partial induced voltage coefficient concept,and discusses the influence of location of the positive feeder on induced voltage in communication by calculation of the partial inductive voltage coefficient λ S related to the feeder location,and a conclusion is that the positive feeder should be located on the outside of the pole when the distance between the communication line and railway line is less than 4 5 m ,and it is better to locate the positive feeder on the inside of the pole when the distance is more than 4.5 m .
