摘要
本文论述了变极调速转速转换控制的原理及转换参数的确定,并对该装置作了简要介绍。这种新研制的转换器采用了信号鉴幅电路,可根据信号电压的大小,来判断电机工作状态。利用电流与时间环节的配合控制电机工作,不引进辅助触点,增加了可靠性。该装置还具有由高速向低速转换的功能。
Tne paper discusses the theory of change-over speed adjustment and determination of change-over parameter, introduces the device in brief. This newly developed converter adopts amplitude discrimination circuit to discriminate the operating condition of the motor according to the change of signal voltage, to control the motor by means of the fitness of the link between current and time, no auxiliary contacts are used to insure reliability. The device also has the function of speed change from high to low.
