铜铬锆接触线在俄罗斯莫喀高铁的适应性分析

Adaptability Analysis of CTCZ Contact Wire in Moscow to Kazan High-speed Railway

俄罗斯莫斯科至喀山高速铁路是国内外首条时速400km高速铁路项目,更高速度对负担电能传输和机械滑道的接触线提出了更高的性能要求,本文围绕莫喀高铁接触网系统接触线选型,分别从抗拉强度、导电率、耐磨性等,分析了铜铬锆接触线在时速400km/h的高速铁路的适应性,确定了莫喀高铁接触网系统接触线类型,同时也为今后时速400km/h的高速铁路接触线选型提供了参考。

Moscow to Kazan electrified railway is the first 400 km/h high-speed railway project in the world,higher speeds put higher demands on contact wires for power transmission and mechanical slideway.In this paper,the adaptability of CTCZ contact wire in 400km/h high-speed railway is analysed from tensile strength,conductivity,wear resistance and other contact wire properties,and the contact wire type of Moscow to Kazan high-speed railway contact wire is determined,which also provides reference for the selection of contact wire of 400km/h high-speed railway in the future.
