摘　　要：本文对8K机车在再生制动工况下,因网压突降导致再生失败的原因进行了分析,并对其改进电路——恢复换相电路的工作原理作了详细介绍。这一改进对目前国产再生机车的设计具有一定的参考价值。It is analyzed here the causes for failure of regeneration during regenerative braking of 8K electric locomotive, and then it is introduced the working principle of improved circuit—recovering commutation circuit. This improvement is a orthwhile reference for the design of locomotives with regenerative braking in our country.
