摘要
本文介绍了8K型电力机车电制动和电—空联合制动的特性。分别从主电路和控制电路阐明了再生制动的原理以及制动电流的调节和控制。文章还分析了再生制动时主变流器的换相过程,并对跳弓拉弧时引起再生颠覆的原因也作了说明。
An introduction is made about the characteristics of the electrodynamic braking and electro-pneu matic blended braking of 8K electric locomotive. It is illustrated respectively in the paper the principle of regenerative braking and regulation and control of the braking current in terms of the power circuits and control circuits. The main converter commutation process due to regenerative braking is also analyzed, and reasons of regenerative overturn caused by pantograph jumping and arcing are explained.
