铁路通过能力和运输能力的提高,要求提高列车的运行速度和重量,因而也就要求提高机车的功率。随着运行速度的提高,功率的增长与速度成平方关系。目前,苏联铁路上运行之货运电力机车的小时功率为5250~6520千瓦,客运电力机车的小时功率为4620~5100千瓦。试验型11型(三节)和200型电力机车的功率大于8000千瓦,而内燃机车的额定功率要小得多(表
The improvement of railway passing capacity and transport capacity requires that the running speed and weight of trains be increased, and thus the power of locomotives is also required to be increased. As operating speed increases, power increases in a square relationship with speed. At present, the hourly power of freight electric locomotives operating on the Soviet railway is 5250 to 6520 kilowatts, and the hourly power of passenger electric locomotives is 4620-5100 kilowatts. Test 11 (three) and 200 electric locomotive power greater than 8000 kW, while the rated power of diesel locomotives is much smaller (table
