摘要:
受电弓碳滑板是影响列车安全运行的关键设备。针对北京地铁6号线(以下简称“6号线”)西延线开通后出现的受电弓碳滑板异常磨耗问题，从碳滑板材质特性、接触网拉出值斜率、弓网接触压力等方面分析了可能造成6号线碳滑板出现异常磨耗问题的原因，并针对性地给出了解决碳滑板异常磨耗的有效方法，包括定期打磨和更换碳滑板、选择导电率较低的碳滑板、调整交错式锚段关节处地接触线间距、安装弓网压力检测装置等，使弓网关系的匹配值达到最优，从而达到减少碳滑板异常磨耗的目的。
Abstracts:
Pantograph carbon strip is the key component affecting train operation safety. Aiming at the pantograph carbon strip abnormal wear problem appeared after the launch of Beijing Metro Line 6 west extension (hereinafter refer to as ′Line 6′), the possible causes of Line 6 carbon strip abnormal wear are analyzed from aspects such as carbon strip material properties, slope of catenary stagger value, and pantograph catenary contact pressure. To solve these problems accordingly, effective solutions are given such as regular grinding and carbon strip replacement, choosing carbon strip with low conductivity, adjusting the contact line spacing at the staggered anchor joint, and installing pantograph catenary pressure detection device, so that pantograph catenary matching degree is optimized, achieving the goal of carbon strip abnormal wear reduction.
