基于光纤通信的城市轨道交通直流牵引双边联跳装置研究

Research on DC traction Two-way Inter-tripping Device of Urban Rail Transit Based on Optical Fiber Communication

针对地铁直流牵引供电系统现有的双边联跳保护方案存在的问题,介绍一种新开发的基于光纤通信的直流牵引双边联跳装置,阐述了装置的软、硬件设计思路和工作原理。

In view of the problems in the current two-way inter-tripping protection scheme of the DC traction power supply system for subway,this paper introduces a newly developed DC traction two-way inter-tripping device based on optical fiber communication,and expounds the software and hardware design ideas of the device and its operating principle.
