内容简介电传动内燃机车最大优点之一是能实现恒功调节,使柴油机处在最佳工况运行。至目前为止,实现恒功率调节方法常见的有三种。 1.采用特制的复励励磁机,外加功率伺服电机。特点是主发电机有基本双曲线,但励磁机复杂,系统大而重,恒功精度差。 2.通过函数发生器、乘法器等电子器件构成的电调恒功。优点是技术先进、体积小、有较高的恒功精度。但如果不把调速器的功率信号引入,则只能够恒主发电机功率。 3.带有联合调节器的恒功装置,即“油马达”式,优点是恒定柴油机功率,且精
Introduction One of the biggest advantages of electric drive diesel locomotive is that it can realize constant power regulation and make the diesel engine run in the best working condition. So far, there are three common ways to achieve constant power regulation. 1. Using a special complex excitation exciter, plus power servo motor. Characteristic is the main generator has a basic hyperbolic, but the exciter is complex, large and heavy system, constant power accuracy. 2 through the function generator, multiplier and other electronic devices constitute the ESC constant power. Advantages are advanced technology, small size, high constant power accuracy. However, if the governor power signal is not introduced, only the main generator power. 3. Constant power device with integrated regulator, that is, “oil motor” type, the advantage of constant diesel engine power, and fine
