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 line with the implementation of the new railway Shitai Passenger Dedicated Line project, based on the introduction, digestion and absorption of foreign advanced contact wire switch layout technology, the passenger line of 18 # turnout catenary arrangement is studied for the construction of Shijiazhuang Passenger Dedicated Line provide technical support. Research conclusions: Simple and non-intersecting layouts The front-line catenary has no crossover with the side catenary and is easy to place and install. The non-intersecting arrangement with guided suspension is located between the front catenary and the side catenary. The area-oriented catenary is always in contact with the pantograph so that the pantograph smoothly transitions from the side line to the positive line or from the positive line to the side line so as to reduce the impact on the positive catenary and the guide contact line does not appear non- Normal wear and tear, the arrangement of the speed of adaptability better bow network flow better. Shijitong Passenger Line for the first time in China. Proposed to promote the construction of passenger dedicated line.
