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-intersecting layout of catenary with auxiliary suspension at 42 # turnout is discussed. The layout and installation design of catenary are analyzed. Auxiliary catenaries without auxiliary arrangement are located between the main line and the side catenary and are always in contact with the pantograph near the fork’s center of the switch so that the pantograph can smoothly transition between the main line and the lateral line, The impact on the positive catenary is reduced and the auxiliary catenary does not appear abnormal wear. The arrangement of the utility model has the advantages of good speed adaptability and better performance of the bow net, and is proposed to be popularized and applied when the catenary arrangement of the large number of turnout of the passenger dedicated line is arranged.
