介绍牵引工矿电机车的电气原理及电气控制功能,通过采用交流变频调速电传动技术,经直—交牵引变频调速器将直流电逆变成三相交流电,供给交流牵引电动机用以驱动轨道维护机车,阐明了该种电机车电路系统的设计思路、工作原理、硬件构成及技术参数的计算、元件选择等,完成了电机车电气控制功能的电路系统设计。
This paper introduces the electrical principle and electrical control function of tractor locomotive electric locomotive. By adopting AC variable frequency speed control electric drive technology, the direct current is inverted into three-phase alternating current through direct-cross traction inverter governor, which supplies AC traction motor to drive track maintenance Locomotive, and illustrates the design idea, working principle, hardware composition, calculation of technical parameters and component selection of the electric locomotive circuit system, and completes the circuit system design of the electric locomotive electric control function.
