摘要
研究目的:研究电气化铁道接触网承力索特别是铝包钢、铜或铜合金承力索在运行中引起磨损,甚至发生断股、断线事故的原因及预防措施。研究方法:通过对接触网承力索的现状和主要防磨损措施的研究来进行分析。研究结果:提出了防止承力索磨损的主要技术措施:采用单根铁线连续绑扎、匹配悬吊滑轮与承力索表面硬度、采用辅助绳悬挂承力索及采用承力索预型保护条。研究结论:道岔柱应采用双腕臂结构、特殊设计来避免承力索间相互碰磨、改善承力索悬挂结构及使用承力索预型保护条。采用承力索预型保护条是解决承力索磨损的有效技术措施。
Research purposes: The research is made on the cause for the wear and breaking of catenary of electrified railway and its preventive measures, especially for aluminum covering steel wire and aluminum covering copper wire or copper alloy catenary.
Research methods:The analysis is made for the present situation of catenary of overhead contact wire system and main measures against wear of it.
Research results:The main technical measures against wear of catenary are proposed, that are to tie up continuously with single iron wire, match the surface hardness of hanging pulley with that of catenary and use auxiliary cable suspension catenary and preformed protection line for catenary.
Research conclusions:The structure of double cantilevers and special design should be adopted to turnout mast for the purpose of avoiding wear between catenaries, improving suspension structure of catenary and allowing usage of preformed protection line for catenary. Application of preformed protection line is an effective technical measure for solving the problem of wear.
