铁路枢纽站场信号黄闪黄电路设计优化

Design Optimization of Yellow-fl ash-yellow Circuits of Railway Hub Station Signal

针对在铁路枢纽或咽喉区较长的特殊站场中,会出现进站信号机或接车进路信号机与信号楼间控制电缆长度约达3 km的情况,其黄闪黄信号显示存在不稳定或者不能正常开放的问题,从工程设计角度进行分析研究,提出设计优化解决方案。

In view of the situation that the length of the control cable between the home signal(or the receiving signal)and the signal tower is about 3 km in the railway hub or the special station with long throat section,the yellow-fl ash-yellow signal aspect is unstable or cannot be displayed normally.This paper analyzes and studies this problem from the perspective of engineering design,and puts forward the design optimization solution.
