摘　　要：由于电力机车受电弓碳滑板易损易耗的特点,使得用户对碳滑板的使用需求量较大,更多的生产企业参与到电力机车受电弓碳滑板的试制。为做好机车受电弓碳滑板试制阶段的在线试用工作,有必要对试制的机车受电弓碳滑板进行科学的在线适应性试用研究。文章汇总并分析了既有服役碳滑板可能出现的失效形式及其形成原因,阐述了机车受电弓碳滑板在线适应性试用的必要性,同时归纳了机车受电弓碳滑板在线试用的前提条件;并且从试用装车数量与周期、试用期间的跟踪和监测、试用结束后的拆检、试用结果评价、安全应急预案等5个方面设计制定机车受电弓碳滑板在线适应性试用方案。将该试用方案应用于国内某型机车受电弓碳滑板,线路试用过程和试验数据综合验证了该试用方案的可行性,未影响既有电力机车的正常运营服役。经验证的试用方案能够全面反映和评价新试制机车受电弓碳滑板在线运用的适应性与质量可靠性,并能够有效指导相关方在机车受电弓碳滑板试用现场的实际操作,降低了机车受电弓碳滑板在线试用的安全风险,同时为机车受电弓碳滑板的批量装车提供重要技术支撑。As one of consumable parts for railway electric locomotives,pantograph carbon contact strips are largely demanded,and more manufacturers engage in the trial production of pantograph carbon contact strips for electric locomotives.The current study is necessary in order to improve on-track trial operation of pantograph carbon contact strips for locomotives in the trial production stage.This paper summarized and analyzed the potential failure modes and corresponding causes of the carbon contact strips in service,expounded the necessity of the on-track adaptability trial for them,and summarized the preconditions of the on-track trial operation.In addition,an on-track adaptability trial scheme of pantograph carbon contact strips for locomotives was designed,covering five aspects of loading quantity and cycle of trial operation,tracking and monitoring during trial operation,disassembly and inspection after trial operation,evaluation of trial results and safety emergency plan.This scheme was applied to a new type of pantograph carbon contact strips for locomotives produced by a domestic manufacturer.The on-track trial process and test data comprehensively proved the feasibility of this trial scheme,not involving any effect to the normal operational service of the locomotive.The trial scheme can fully reflect and evaluate the adaptability and quality reliability in the on-track application of new locomotive pantograph carbon contact strips in trial production,and effectively guide the relevant parties in the actual operation of the pantograph carbon contact strips for locomotives on the trial site,thus reducing the safety risk of the on-track trial,and provide important technical support for the mass loading of pantograph carbon contact strips on locomotives.
