摘　　要：在互感器校验台体中测量精度等级为S级电流互感器时,调压器的升降由交流电机控制,无法控制调压器上升和下降的速度,导致电流经常错过检定点。本文设计一种基于L298N的直流电机调速系统,采用脉宽调制技术,实现由直流电机控制调压器时,调压器升降速度可控,正反转可控,有效解决了交流电机无法控制速度导致的问题。When measuring Class S current transformer in the transformer calibration table, the rise and fall of the voltage regulator is controlled by the AC motor, and the speed of the rise and fall of the voltage regulator cannot be controlled, resulting in the current often missing the calibration point.This paper designs a DC motor speed regulating system based on L298N. When the DC motor controls the voltage regulator, the speed of the voltage regulator can be controlled, and the forward and reverse rotation can be controlled. This effectively solves the problem caused by the AC motor’s inability to control the speed.
