Analysis on the Daqin Line Heavy Haul Traction Electrical Locomotive Synchronous Control System Brake Valve Cut-out Failure

This paper introduces the brake valve cut-out issue in the synchronous operation system,explains the principle of the brake valve cut-out,reasois and categroy of failure.It also analyzed the means to minimize the brake valve cut-out and measures to modify the system flow algorithm,periodically calibrate the BP flow transducer and flow transducer,optimize locomotive driver＇s operation, strengthen the daily maintenance for locomotive and synchronous control system.The one-year on line experience proves that failure rate drops dramatically.It ensures the normal operation of the synchronous control system on the Daqin Line.
