城市轨道列车电磁兼容的系统布局设计实现及测试

Design and Test of Electromagnetic Compatibility System Layout for Urban Railway Vehicles

当今我国城市化进程飞快,轨道交通系统愈发变成解决城市车辆拥堵和公路资源紧张的一剂良药,其中轨道交通系统的电磁兼容问题是城市轨道列车安全可靠运营的重要保障。为此,本文提出了一套轨道列车电磁兼容系统布局方案,设计给出了轨道列车的电气设备布局和电气配线布局。按照车体设备的分布将轨道列车分为车顶、车内和车底3个部分,并且进行了电磁兼容分区布局设计。最后,以上海地铁6号线作为测试车辆,按照所提布局方案进行了测试,结果表明,本文所设计的方案可以在复杂城市电磁环境下大大提高城市轨道列车的电磁兼容性能,达到了预期的设计目标。

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.
