摘　　要：可控硅脉冲调速方式具有启动牵引力大,调速均匀,无电能损耗,能实现无级启动等特点,极大地改善了矿用电机车的启动和调速性能。但在可控硅脉冲调速过程中出现的失控现象,常会使电机车损坏或者造成运输事故。因此,分析脉冲调速中的失控故障现象,并且采取相应的处理措施,才能保证矿用电机车的正常运行,以实现煤矿的安全生产。SCR pulse speed has a starting speed traction large, uniform speed, no power loss, can realize stepless start etc., greatly improved the mining electric locomotive of the start-up and speed performance. However, in the SCR timing pulse arising in the process ＂out of control＂ phenomenon, and often make or cause damage to motor vehicle transport accidents. Therefore, the analysis of pulse timing in the runaway failure phenomenon and take appropriate measures to deal with in order to ensure the nor- mal operation of mining electric locomotive to achieve safe production in coal mines.
