我段担当的牵引区段普雄至燕岗间有长大下坡道,东风型内燃机车在该区段运行时,要长时间的使用电阻制动。内燃机车在电阻制动工况时,主发电机发出的电只用来给牵引电动机激磁,耗费柴油机功率很少,柴油机接近于空转工况。例如,在电阻制动工况时,主手柄放在12位,主发电机给牵引电动机的激磁为600安,电压为25伏,功率仅为15千瓦,柴油机采用双侧供油,油泵调整齿杆的供油刻度为3.9,若采用单侧供油为5刻度,与主手柄在12位时柴油机空转的供油刻度很近似(双侧
I take the lead section of the Puxiong to Yan Kong has grown up and down the ramp, Dongfeng diesel locomotive in the operation of the sector, the resistance for a long time to use braking. Diesel locomotive resistance braking conditions, the main generator of electricity is only used to give traction motor excitation, consumes little diesel power, diesel engine close to idle conditions. For example, in the case of a resistive braking condition, the main handle is placed at 12-position, the main generator energizes the traction motor with an excitation of 600 amperes and a voltage of 25 volts and a power of only 15 kilowatts. The diesel engine uses double- Rod fuel supply scale of 3.9, with one side of the fuel supply for the 5 scale, and the main handle in the 12-bit diesel engine idling fuel supply scale is very similar (both sides
