某高铁车站42#道岔渡线上接触网关节式电分段设计研究

Research on the Design of Joint-type Electric Sectioning of Overhead Contact System on 42#Turnout Crossover at a High-speed Railway Station

文章通过对比分析器件式及关节式电分段适用条件,探讨了某高铁车站42#道岔渡线上设置接触网电分段设计方案。然后重点介绍了四跨绝缘关节式电分段平面布置和腕臂安装设计,该形式电分段既能满足接触网电气分段的要求,又能使列车以160 km/h的侧向速度通过42#道岔。该布置方式速度适应性好,受电弓在正线和侧线之间过渡平稳,接触线磨损小,弓网性能较好,为42#道岔渡线上设置接触网电分段提供了参考。

By comparing and analyzing the applicable conditions of device-type and joint-type electric sectioning,this paper discusses the electric sectioning design scheme of overhead contact system on 42#turnout crossover at a highspeed railway station.Then,the plane layout of four-span insulated joint-type electric sectioning and the installation and design of cantilever structure are mainly introduced.This type of electric sectioning can not only meet the requirements of overhead contact system electric sectioning,but also enable the train pass through 42#turnout at a lateral speed of 160 km/h.The layout has the characteristics of good speed adaptability,smooth transition of pantograph between main line and side line,small wear of contact line and good performance of pantograph and overhead contact system,which provides a reference for setting electric sectioning of overhead contact system on 42#turnout crossover.
