摘要
本文介绍了我国最大功率级斩波调速工矿电力机车的研制特点及运行情况。该车采用了4相不重的斩波主电路和先发副脉冲、后发主脉冲及4相集中移相的控制方式,并特别试制了适用于斩波的滤波电容器及换相电容器。运行实践表明,该车不但运行可靠,而且,具有显著的节能效果和经济效益。
The developing features and operation of this kind of locomotive are mainly introduced.The locomotive adopts chopper main circuit of 4 uncombined phases and a control mode featuring accessory pulse generated firstly, main pulse secondly, and central phase shifting of the 4 phases. Special filter capacitor and commutating capacitor have also been made to fit the chopper.Running practice shows that it can not only operate reliably, but also obtain remarkable energy-saving and economic effects.
