摘要:
[目的]基于刚性接触网拉出值 “八”字布置方案,分析影响刚性接触网弓网磨耗的原因,提出改善弓网磨耗的措施。[方法]介绍了电气磨耗和机械磨耗的原理及解决这两类弓网磨耗的措施。重点研究影响弓网间机械磨耗的因素之一“拉出值布置方式”。结合实际工程项目,利用定量统计方法,分别从拉出值扫动频率大小、相邻两锚段内悬挂点拉出值扫动频率的一致性和关节悬挂点相对线路中心线位置3个方面分析刚性接触网拉出值 “八”字布置方案对弓网磨耗的影响。[结果及结论]在刚性接触网拉出值采用 “八”字布置方案情况下,适度增大拉出值扫动频率值、保持相邻两锚段内悬挂点拉出值扫动频率的一致性和关节悬挂点位于线路中心线同侧,这些措施都有利于改善碳滑板磨耗的均匀程度。

[Objective]Based on the “八-shaped” layout scheme of the rigid catenary stagger value, the factors affecting the pantograph-catenary (PC) wear of the rigid catenary are analyzed and measures to improve the wear are proposed.[Method]The principles of electrical wear and mechanical wear, and the measures to solve these two types of PC wear are introduced. One of the factors affecting the mechanical wear between the pantograph and the catenary, that is, the “layout mode of the stagger value” is studied with emphasis. Combining with actual engineering projects and using quantitative statistical methods, the influence of the “八-shaped” layout scheme of the rigid catenary stagger value on the PC wear is analyzed from three aspects: the magnitude of the sweeping frequency of the stagger value, the consistency of the sweeping frequencies of the stagger values at the suspension points within two adjacent anchor sections, and the position of the suspension points at the joints relative to the track center line.[Result & Conclusion]When the “八-shaped” layout scheme of the stagger value is adopted for the rigid catenary, measures such as increasing moderately the sweeping frequency value of the stagger value, maintaining the consistency of the stagger value sweeping frequencies at the suspension points within two adjacent anchor sections, and keeping the joint suspension points located on the same side of the track center line, are conducive to improving the uniformity of the wear of the carbon slide plate.
