| Summary: | 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. |
