内燃机车的发展特别受到功率传递设备发展的制约。在苏联、美国、英国和法国,电力传动装置得到了广泛的应用。统计研究表明,单节功率在1500千瓦以上的内燃机车在国际范围内,绝大部分采用的是电力传动。这种电力传动设备所以得到广泛应用,这是因为主要使用串激直流电动机作为牵引电动机所决定的。这种电机的特性曲线与内燃机车 The development of diesel locomotives is particularly constrained by the development of power transfer equipment. In the Soviet Union, the United States, Britain and France, electric power transmission device has been widely used. Statistical studies show that the single-section power of more than 1500 kilowatts diesel locomotive in the international context, the vast majority of the use of electric drive. This kind of electric transmission equipment is widely used because of the main use of a series DC motor as a traction motor. The characteristic curve of this kind of motor and diesel locomotive
