摘要
本文利用作者首次提出的外界电磁场对地下传输系统激励耦合的等效传输线方程及其一般解，建立了交流电气化铁路对地下传输系统干扰影响的分析方法。研究了电气化铁路接触网及其回流系统对地下无限长导体的耦合问题，得出了导体沿线感应电流和感应电位的计算公式。此外，还讨论了双轨中回流对干扰的等效屏蔽作用。
A more general approach to analyse and calculate the coupling of the contact power lines and their return currents with underground conductors is presented on the basis of equivalent transmission line equations forwarded previously by the author.By this approach,the interference of contact power system with infinitely long underground conductors is studied,and the currents and potentials induced along two underground conductors are calculatedrespectively. Furthermore, the equivalent shielding effect of the current in the two tracks against the interference is discussed.
