摘　　要：无交叉线岔是高速铁路接触网的关键设备,是受电弓在正、侧线之间转换的纽带,其运行安全对弓网匹配提出了较高要求。针对沪昆高铁贵州段18号无交叉线岔在运行中出现的刮擦受电弓弓角、接触线磨损等问题隐患进行剖析,对接触线的空间位置建立几何模型,推导正、侧线之间空间位置的关系曲线,分析研究始触区侧线跨中偏移对弓网过渡的影响,并提出优化建议方案,以提高18号无交叉线岔弓网过渡的安全可靠性。As the key equipment of high speed railway OCS,tangential point wiring is the link for pantograph transition between the main track and the side track,whose safe operation has stringent requirements for pantograph-catenary matching.This paper analyzes the hazards such as pantograph horn scratching and contact wire wear in the operation of No.18 tangential point wiring in Guizhou Section of Shanghai-Kunming High Speed Railway,establishes a geometric model of the spatial position of the contact wire,derives the curve of relationship between the spatial positions of the main track and the side track,studies the influence of the midspan offset of the side track in the initial contact area on the pantograph-catenary transition,and proposes the optimization scheme,which improves the safety and reliability of the pantograph-catenary transition of No.18 tangential point wiring.
