摘　　要：随着高铁、城市轨道交通的普及,设备及其电缆在电力牵引环境下的应用越来越多,很多电缆在这样的环境下都会因电磁耦合效应产生一定的纵向感应电压。这类纵向感应电压极有可能因为设备维护人员的误触摸而产生电击伤害,也有可能因为产品设计的不合理导致设备的损坏、误操作等诸多问题。本文中列举了这类纵向感应电压评估计算的三种不同实现方式,并对三种方式得到的差异化结果做了分析比较,并对差异原因一一做了分析。With the spreading of high-speed rail and urban rail transit,equipment and its cables are increasingly used in electric traction environments,and many cables will produce a certain longitudinal induced voltage due to electromagnetic coupling in such an environment.This type of longitudinal induced voltage is highly likely to cause electric shock damage due to accidental touch by equipment maintenance personnel.In this paper,three different implementations of such longitudinal induced voltage evaluation methods are listed,and the differentiated results obtained by the three methods are analyzed and compared,and the reasons for the differences are analyzed one by one.
