青山矿、高坑矿运输区广大职工发扬敢想敢干的革命精神,自一九七三年八月以来,在湘潭电机厂的协助下,分别成功地安装了8T 和2.5T 蓄电池电机车可控硅脉冲装置。脉冲调速主回路为一直流断续器,控制回路为小可控硅双稳态触发电路。控制方式为定宽调频方式。调节断续器的工作频率,达到调节电动机转速的目的。由于甩掉了起动电阻器,可节约电能
Since August 1983, with the help of Xiangtan Electric Machinery Factory, the majority of staff and workers of Qingshan Mine and Gaokeng Mine Transportation Zone have successfully promoted the revolutionary spirit of daring to think and dare to successfully install 8T and 2.5T battery electric vehicles respectively Silicon controlled pulse device. Pulsed speed main circuit is a DC interrupter, the control circuit is a small silicon bistable trigger circuit. The control method is constant width FM mode. Adjust the operating frequency of the interrupter to achieve the purpose of adjusting the motor speed. Due to get rid of the start resistor, can save power
