摘要

研究目的：目前复线电气化铁路建设很快，复线并行线路的感应电压导致人身伤亡的事故时有发生。为解决这个问题，制定出正确的防护措施，分析感应电压机理，研究感应电压的大小，推理出感应电压的准确计算公式很有必要。本文根据电磁场理论中的唯一性定理———镜象法，分析推导出电影响和磁影响感应电压的计算公式，论证出电影响和磁影响感应电压的精确计算公式。

研究结论:当带电接触网导线通过交流电流时，接触网导线周围形成电场和磁场，电磁场对邻近的停电接触网导体产生电磁影响，电影响感应电压与带电线路电压成正比，磁影响感应电压与牵引电流的大小及并行长度成正比，总的感应电压是两种感应电压的矢量和。

Abstract

Research purposes: At present，the double － track electrified railway has developed rapidly，the personal injury accidents caused by the induction voltage from the traction electric network of electrified railway occurs sometimes． For solving this problem，the preventive measures should be offered through making the analysis of the induction voltage mechanism，doing research on the strength of the induction voltage and knowing the calculation formula for the induction voltage． This paper offers the accurate calculation formula for the induction voltage caused by electromagnetic with the image method of the electromagnetic field theory．

Research conclusions: When the current passes through the catenary wire，the electric and magnetic fields form the around the catenary wire，and the electric and magnetic fields produce magnetic effects on the near conductors of the traction electric network． The strength of the induction voltage caused by electrify is proportional with the voltage strength of electric wire and the induction voltage caused by magnetics is proportional with the strength of the traction current and parallel length while the total induction voltage is the vector sum of the two induction voltages．
