摘要:
目的］检查发现洛阳地铁1号线自试运营以来存在弓网关系恶劣、正线发生弓网拉弧现象，检查发现受电弓碳滑板上有灼烧点且磨耗严重。为解决受电弓碳滑板异常磨耗问题，须研究弓网异常磨耗原因，并提出解决措施。［方法］重点探讨了弓网技术性能、碳滑板材质、弓网打磨、接触压力、外部气候环境温度及湿度等因素对受电弓和接触网磨耗的影响，探讨了弓网异常磨耗的影响因素和磨耗规律。［结果及结论］研究结果表明，洛阳地铁1号线受电弓碳滑板磨耗为中心偏磨型磨耗，为解决此类磨耗问题，特提出针对性的处理措施和预防建议，包括建立接触网、受电弓的专项台账，借鉴同行对弓网异常磨耗的应对经验，根据弓网磨耗情况优化检修方式，充分运用弓网检测棚等信息化检测设备来提升弓网技术参数的监控和调节效率等。
Abstracts:
［Objective］ During inspection, problems like the bad pantograph and catenary relation, pantograph-catenary arcing on the main line, burning points and serious wear on the pantograph carbon strip are detected since the trial operation of Luoyang Metro Line 1.In order to solve the abnormal wear of pantograph carbon strip, it is necessary to study the causes and put forward solutions. ［Method］ The influence of the technical performance of the pantograph catenary, carbon strip material, the pantograph catenary grinding, contact pressure, external climate environment temperature and humidity on the pantograph catenary wear is mainly discussed. The influencing factors and the pattern of the pantograph catenary abnormal wear is examined. ［Result & Conclusion］ The research results show that the pantograph carbon strip wear on Luoyang Metro Line 1 is of central partial wear type. In order to solve such wear problems, targeted treatment measures and prevention suggestions are proposed, including establishing special accounts for catenary and pantograph, drawing on experiences of the peers in dealing with abnormal wear of the pantograph catenary, optimizing the maintenance mode according to the wear condition of the pantograph catenary, and making full use of information testing equipment such as the pantograph catenary inspection shed to improve the efficiency of monitoring and adjusting the technical parameters for pantograph catenary.
