针对电阻调速电力机车的耗电量大、牵引能力较低、不适合经济运行的缺点,通过对西露天矿1213#电力机车进行斩波调速改造,介绍了斩波调速原理以及改造后斩波调速机车的优越性能。
Aiming at the shortages of high power consumption and low traction capacity of resistance speed regulating electric locomotive, it is unsuitable for economic operation. Through the chopper speed regulation of 1213 # electric locomotive in western open pit mine, the principle of chopper speed regulation and the principle of speed regulation Chopper speed locomotive superior performance.
