在 2 0 0 0年 ,我段机车电阻制动带通风机电机频频烧损 ,特别是电机换向器表面烧伤尤为严重。机车电阻制动不能使用时 ,列车在通过长大下坡道时只能靠空气制动 ,势必造成列车运行中的冲动。针对这一问题 ,我们对烧损的电机进行了仔细的检查分析 ,确认这种情况是电阻制动通风机
In 2000, I paragraph locomotive resistance brake band fan motor frequent burning, especially the motor commutator surface burn is particularly serious. Locomotive resistance braking can not be used, the train through the growth of the downhill can only rely on air braking, is bound to cause the train running impulse. In response to this problem, we conducted a careful inspection and analysis of the burnt-out motor to confirm that this situation is a resistor-brake ventilator
