摘　　要：针对电气化铁路的部分供电网随着运量的不断增长,电网容量严重不足,供电网压不断降低,严重导致某些地区机车辅机烧损问题,从南昆线机车辅机烧损的实际情况出发,提出了一种投资少、见效快的解决方案,并详细阐述其具体实现原理与实施策略。With traffic growth of electrified railway, some power grid capacity was seriously shortage and supply network voltage was falling, which leads to locomotive auxiliaries constantly burning-out. Aimed at the actual situation of locomotive auxiliary engine burning on Nanning-Kunming line, a low-cost and effective solution was put forward, implementation principles and operation strategy of which were elaborated.
