内燃机车主发电机自励磁装置的研究

Research on self-excitating device of diesel locomotive generator

对我国内燃机车主发电机励磁系统采用的励磁机组励磁方式进行改进 ,利用三相全控桥对辅发发出的三相交流电进行整流给主发励磁的方式 ,省去了主发励磁机组 ,减少主发励磁系统的维护量 ,方便机车系统整体的布置 ,为内燃机车辅助系统的改造升级提供空间。

The traditional excitating system with exciter set is reformed.Using three-phase controlled bridge,the three-phase AC generated by auxiliary generator is rectified and then the main generator is excitated.This reformation omits the exciter set,which decreases the maintenances and makes thing convenient for arranging the whole system.Its also of benefit to the reformation of auxiliary system.
