The invention relates to a locomotive automatic neutral section passing method and device, belongs to the technical field of locomotive control, can effectively reduce the power loss time of the locomotive in the neutral section passing process, prevents double-bow operation from passing through neutral section, and is simple and reliable in control principle and easy to implement. According to the technical scheme, a locomotive pantograph signal, a locomotive speed signal, a locomotive power signal and a network voltage signal are integrated as a control basis to adjust the output time of each control signal in the automatic neutral section passing process of the locomotive, and before the locomotive enters neutral section, the pantograph signal is combined with the locomotive speed signal and the locomotive power signal to adjust the locomotive unloading power and the main circuit breaker breaking time; after neutral section passing, the network voltage signal is used as a basis forcontrolling the locomotive to close a main circuit breaker and load locomotive power, the pantograph signal is judged before the locomotive passes through neutral section, and if the locomotive runs in a double-pantograph mode, one pantograph is immediately forced to descend, so that only one pantograph is kept running.
本申请为一种机车自动过分相控制方法及装置,属于机车控制技术领域,可有效减少机车在过分相过程中的失电时间,并防止双弓运行通过分相,控制原理简单、可靠,易于实现。其技术方案为:综合机车受电弓、机车速度、机车动力和网压信号作为控制依据来调整机车自动过分相过程中各项控制信号的输出时间,在进入分相前,以受电弓信号结合机车速度、机车动力来调整卸载机车动力和断开主断路器的时间,在通过分相后,以网压信号作为控制机车闭合主断路器和加载机车动力的依据,机车过分相前判断受电弓信号,如为双弓运行,则立即强制降下一个受电弓,从而保持只有一个受电弓运行。
