制造矿用架线式电机车脉冲调速器必须解决的问题是消除引起主线路换流中断的条件。矿用直流电机车的现有脉冲调速器的控制装置都是按使用主振荡器的原理制造的。这种控制装置(图1a)的一个主要元件是主控振荡器,它形成稳频脉冲。输出端 The problem that must be solved in the manufacture of pulse motor speed controllers for mining overhead wire electric locomotives is to eliminate the conditions that cause the interruption of the commutation of the main circuit. The existing pulse speed governor controls for mining DC motors are based on the principle of using the main oscillator. One of the major components of this control device (Figure 1a) is the master oscillator, which forms a frequency-stabilized pulse. Output
