目前,国内许多矿区都进行了电机车的可控硅脉冲调速试验,取得了可喜的成果。但是,在试验过程中,程度不同的都发生过失控现象。电机车失控往往造成的后果是很严重的,这就在一定程度上成为影响该项技术大量推广的重要因素。针对这一主要因素,我们从试验中发现,失控主要发生在: At present, many domestic mining areas have carried out a TRV pulse motor speed control test, and achieved gratifying results. However, in the course of the experiment, the degree of uncontrolled phenomena have occurred. The consequences of loss of control of electric locomotives are often very serious, which to some extent become an important factor affecting the mass promotion of this technology. In response to this major factor, we found from the experiment that out of control occurs mainly in:
