摘要
伴随着城市化进程和城市面积的扩张,城市轨道交通成为了人们出行的主要交通方式。而在现代城市中,电气网络、移动通信网络无处不在,产生了多种多样的电磁波和电信号,它们构成了复杂的电磁环境,会引起城市轨道交通的严重电磁兼容问题。为了解决这个问题,本文提出了复杂电磁环境下城市轨道交通的电磁兼容设计,并以上海地铁6号线项目为例,在实际测试中检验了该电磁兼容设计符合标准的有效性和可靠性。在该设计中,详尽分析了电磁干扰源、耦合路径和敏感设备,并严格设计了接地、屏蔽、滤波和布线等电磁耦合路径切断技术,从而满足了城市轨道交通的电磁兼容性要求。
With the development of urbanization,urban rail transport has become the main transportation method in a city.However,in a modern city,a variety of electrical networks and mobile communication networks are everywhere,and produce various electromagnetic waves and electrical signals,which form a complex electromagnetic environment and result in serious electromagnetic compatibility(EMC)problem in urban rail transport.To resolve such problem,this paper proposes an EMC design scheme for urban rail transport in a complex electromagnetic environment,and verifies its effectiveness and reliability in the actual test by taking Shanghai Metro Line 6 as an example.In this scheme,electromagnetic interference source,coupling path and sensitive devices are analyzed in detail,and the blocking techniques of electromagnetic coupling path,i.e.grounding,shielding,filtering and wiring,are strictly designed to meet the EMC requirements of urban rail transport.
