铁路客运专线对城市地铁电磁干扰分析研究

Electromagnetic Interference of Passenger Dedicated Line to Metro Line

为提高轨道交通的快捷性、舒适性,对各类轨道交通相互结合的紧密度要求越来越高,随之而来的铁路与地铁的相互影响也突显出来,重点分析铁路客运专线与城市地铁衔接后,交流牵引电流对地铁的电磁干扰情况,并提出应采取的相应措施,其研究结论对地铁信号等弱电系统的实施具有一定指导意义。

In order to improve demands for rapid and comfortable transportation of rail transit such as railways, metro lines and light railways, the interrelationship between different transportation modes should be well treated, especially at join area between a passenger dedicated line and a metro line in urban rail transit. This paper analyzes and studies the electromagnetic interference of the railway traction current to the metro line in the coexistence region and puts forward corresponding electromagnetic interference protection measures. The study results have certain guiding significance to implement metro signaling and communication systems.
