试论城市轨道交通刚性接触网异常磨耗机理及防控

Discussion on Abnormal Wear Mechanism and Prevention and Control of Rigid Contact Network in Urban Rail Transit

近年来,我国城市轨道交通的地下车站,主要采用的供电方式是刚性接触网,在地铁运营期间接触网异常磨耗问题是需要首要解决的问题,对列车运行的稳定性和安全性造成严重的影响。基于此,本文分析了城市轨道交通刚性接触网的异常磨耗问题,提出了能够有效进行问题防控的建议,旨在为有效避免异常磨耗对行车安全和稳定性产生的影响提供助力。

In recent years,the main power supply method used in underground stations of ur⁃ban rail transit in China is the rigid contact network.Abnormal wear and tear of the contact net⁃work during subway operation is the primary problem that needs to be solved,which has a seri⁃ous impact on the stability and safety of train operation.Based on this,this article analyzes the problem of abnormal wear of the rigid contact network in urban rail transit and proposes sugges⁃tions for effective problem prevention and control,aiming to provide assistance in effectively avoiding the impact of abnormal wear on driving safety and stability.
