电机车的可控硅无触点脉冲调速是最近几年才发展起来的新技术。由于它具有节省电力、实现无级调速等优点,所以在越来越多的矿山应用起来。几年来,我们与北京矿冶研究院共同试验了1.5吨电机车脉冲调速定频调宽的线路。最近我们又共同试验了定宽调频的线路,运行效果良好。 The SCR silicon non-contact motor speed control is only developed in recent years, the new technology. Because it has the advantages of saving electricity and realizing stepless speed regulation, so more and more mines are applied. Over the past few years, we and Beijing Institute of Mining and Metallurgy jointly tested 1.5 tons of electric locomotive pulse speed fixed frequency line. Recently, we have jointly tested the fixed width FM line, running well.
