摘　　要：本文概要介绍了8G型电力机车的主电路和辅助电路,其主要特点是:主电路采用分裂桥臂交叉供电的双拍整流电路;电气制动为两级电阻制动;辅助电机采用电容分相系统,取消劈相机;过电压保护采用保护特性更佳的过电压限制器,等等。文章还给出了8G机车的特性曲线,列表比较了8G、8K和SS4机车的主要技术参数。A general introduction to the power and auxiliary circuits of 8G electric locomotive is given whose characteristics are as follows, the power circuit uses single phase bridge circuit crossly fed by split type bridge arms; electrical braking employes two-stage rheostatic braking, phase convertor is substituted by capacitor split-phase system for the auxiliary motors, overvoltage protection is accomplished by overvoltage limitator with better protective properties and so on. Characteristiccurves of 8G electric locomotive are given and comparison of the main technical parameters for 8G, 8K and SS4 electric locomotives are presented by table.
