| 摘 要： | 从三相异步电动机的等效电路入手 ,推导出当负载减小时 ,为了节能就必须减小电源电压 ,同时保持M/U1 2 为常数 (等于额定转差率sN)。用单片微机控制双向可控硅的导通角实现在负载变化时 ,调节电源电压使转差率恒定不变 ,并给出实验结果和节电率随负载变化曲线

| Abstract: | Beginning from the equivalent circuits of the induction motor, it is given that for the induction motor to economize electric energy, it is necessary to decrease the power line voltage when its load change lighter, and M/U 1 2(s=s N) remains. The power line voltage is changed with load by single chip microcomputer to control the on angle of the double thyristors, and s=sN is kept constant. The experimental results and the variance graphs of economy power rate with load are also given. |
