摘　　要：正弦交流电路换路时,暂态过程实验研究的关键是开关动作时刻与电源相位角之间的关系。在实验教学中,由于实验环境的限制,利用实物模拟的实验方式,很难实现这种关系。借助电路仿真软件,可以实现从理论分析、实验方法到实验的输出波形和测量数据,一整套完整的研究过程。通过实验结果的分析,给出了一些实际应用例子,加深了对动态电路的认识,提高了学生的实验兴趣。The key of experiment study on the transient process of the sinusoidal AC circuit is the relationship between switching action time and the power phase angle. However,in the experiment teaching,as a result of the limitation of experimental environment,using the method of physical simulation experiments,it is difficult to implement this relationship. By means of circuit simulation software,the students can achieve a complete process of research from the theoretical analysis,experiment method to the experiment output waveform and measurement data,deepened the understanding of the dynamic circuit,and promoted students＇ interest in the experiment.
