Abstract：Currently，the urbanization process in China becomes faster and faster，and the railway transportation system has become a good solution to the traffic jam problem of a city.Its electromagnetic compatibility（EMC）design provides an important guarantee for the safe and reliable operation of urban railway vehicles.For this reason，this paper proposes an EMC layout scheme for urban railway vehicles，and designs their electrical device layout and electrical wiring layout.The urban railway vehicles are divided into the roof，the interior and the bottom according to their device distribution，and their corresponding EMC partition layouts are presented.By taking the Shanghai Metro Line 6 as a test vehicle，the layout scheme is tested.The test results show that the proposed scheme can greatly improve the EMC performance of the urban railway vehicles in a complex urban electromagnetic environment and reach the predefined design goals.

1 緒论

地铁作为一种占地少、运输量大、环境污染小、安全舒适的出行方式，自1969年北京开通第一条地铁线路后，便如雨后春笋般出现在中国各大经济发展较快的城市[1]。而保障地铁在厂内设计符合标准、运行过程中安全无误，是研究轨道列车的首要任务。城市轨道列车自身设备间的电磁干扰与它对整个城市形成的电磁辐射干扰是影响轨道列车安全运行的重大因素。轨道列车中的电气电子系统，例如信号发射系统（包括轨道电路和其他列车探测系统）、列车通行控制系统和铁道旁控制系统等，它们大部分均采用大功率变频器、整流器和各种先进的信号控制网络，这使得轨道列车成为一个在城市中穿行的巨大电磁干扰源。……
