地铁车辆分体式LCU系统的设计与研究

Design and Research of Separated Type LCU System for Metro Vehicles

目前LCU系统被广泛应用于地铁列车中替代传统继电器,并解决传统继电器控制方式普遍存在的故障率高、运维难度大等问题。针对现有LCU系统的应用现状,文章介绍了一种可以灵活编组的分体式LCU系统的设计方案,该设计在保障LCU系统整体可用性的基础上节约了安装空间,增强了系统的兼容性和经济性。建议在后续地铁车辆的LCU系统中考虑加入分体式设计。

At present,LCU system is widely used in metro trains to replace traditional relays,and solve the problems of traditional relay control methods,such as high failure rate and difficult operation and maintenance,etc.In view of the application status of existing LCU system,this paper introduces the design scheme of the separated type LCU system that can be flexibly marshalled,the installation space is saved and the compatibility and economy of the system are enhanced on the basis of ensuring the overall availability of the LCU system in this design.It is suggested that the separated type design can be considered in the LCU system of subsequent metro vehicles.
