客运专线42~#道岔接触网无交叉布置方式研究

Research on Non-crossing Layout of OCS at Point No.42 for Passenger Dedicated Lines

探讨了42#道岔处带辅助悬挂的接触网无交叉布置方案,分析了接触网平面布置和安装设计技术。带辅助悬挂的接触网无交叉布置方式的辅助接触网位于正线和侧线接触网之间,在道岔岔心附近始终与受电弓接触,使受电弓在正线和侧线之间平稳过渡,减少了对正线接触网的冲击,辅助接触线也不会出现非正常磨损,该布置方式速度适应性好,弓网性能更佳,建议在客运专线大号码道岔接触网布置时推广应用。

The non-crossing layout of OCS in 42# point zone with the auxiliary catenary was studied. The plane arrangement and the installation technology were analyzed. The auxiliary catenary is located between the main line and side line,which contacts the pantograph all along in the point center area. So the pantograph can transit smoothly between the main line and the side line. The impulse to the main line OCS was reduced and there is no abnormal abrasion in the auxiliary OCS. The non-crossing layout of OCS with the auxiliary catenary is suitable for a higher running speed,leading to a better pantograph /catenary performance. For the high speed points on the dedicated passenger lines,the non-crossing layout of OCS with the auxiliary catenary is advised to expand the application scope.
