客运专线18^#道岔接触网无交叉布置方式研究

Research on the Non - crossing Layout Mode of OCS in Turnout 18^# Zone of Passenger Dedicated Line

研究目的:为配合新建铁路石太客运专线工程实施,在引进、消化和吸收国外先进接触网道岔布置技术的基础上,对客运专线18#道岔接触网布置方式进行研究,为石太客运专线建设提供技术支持。研究结论:简单无交叉布置方式正线接触网与侧线接触网无交叉,易于布置及安装;带导向悬挂的无交叉布置方式导向接触网位于正线和侧线接触网之间,在道岔岔心附近区域导向接触网始终与受电弓接触,使得受电弓平稳地从侧线过渡到正线或从正线过渡到侧线,从而减小对正线接触网的冲击,导向接触线亦不会出现非正常磨损,该布置方式对速度适应性更好,弓网受流性能更佳。国内首次在石太客运专线中采用。建议在客运专线建设中推广应用。

Research purposes： In order to match the construction of Shijiazhung - Taiyuan Passenger Dedicated Line, the researches are done on the non - layout mode of OCS in turnout 18^# zone based on introducing, digesting and absorbing the foreign advanced technologies for the purpose of providing the technical support to construction of Shijiazhuang- Taiyuan Passenger Dedicated Line. Research conclusions. Simple non - crossing mode is easy to arrange and fix because the system has no crossing between OCS＇on main line and sideline. In this mode, the guiding OCS is between main line and sideline and contacts the pantograph all along in turnout center area, so the pantograph can transit from sideline to main line or from main to sideline, the impulsion to OCS on main line can be reduced and there is no offnormal abrasion in guiding OCS. The non - crossing with guiding catenary mode is adaptive to high-speed railway with feature of better performance of current collection between pantograph and catenary. It is used in China for the first time and should be adopted widely in passenger dedicated line.
