1问题的提出电阻制动是SS4型电力机车牵引列车时进行调速的有效手段,又是当列车空气制动失效时迫使列车停车的最后保障。每台SS4型机车有4套电制通风柜,每套通风柜又装10组电阻元件分别供4台牵引电机电阻制动时使用。电阻元件由电阻带及其附属小配件组成,其状态好坏将影响机车电阻
1 The issue of resistance braking is SS4 electric locomotive traction when the speed of the effective means of control, but also when the train air brake failure to force the train to stop the last guarantee. Each SS4 locomotive has 4 sets of electric fume hoods, and each set of fume hoods is equipped with 10 sets of resistive elements respectively for the use of 4 traction motor resistors. Resistance element by the resistance band and its accompanying gadgets, its status will affect the quality of locomotive resistance
