摘要
针对串电阻调速电机车存在的弊端,提出进行斩波调速改造。本文阐述了IGBT的调速原理,着重分析了斩波调速改造后电机车产生的经济效益和社会效益。
In view of the drawbacks existed in speed regulation of electrical locomotive with series resistance, the transformation of chopping speed regulation is put forward. The paper also expatiates the speed regulation principle of IGBT, emphatically analyzes both economic and social benefits achieved after the transformation of chopping speed regulation.
