三相异步电动机的三相交流调压软启动及节能控制的研究

Study on soft-start with three-phase AC voltage adjustment for three-phase asynchronous motor and on energy saving control

利用saber仿真软件,研究了在三相交流调压软启动电路中,在电机不同负载工况下,控制晶闸管导通角调节三相异步电机的输入电压对电机各部分损耗及功率因数的影响,并利用得出的实验波形及数据对仿真结果进行比较验证。

Using the simulation software of saber,the influence is studied of the motor loss and power factor by the adjustment of input voltage of three-phase asynchronous motor through control on the conduction angle of thyristor, in the soft start circuit with three- phase AC voltage adjustment and at different loads. The simulation results are compared and verified by the test waveform and data achieved.
