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,导致了在这方面研究中有理论、无实验的尴尬局面。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的例子,加深了对动态电路的认识,提高了学生的实验兴趣和加深了理论知识的掌握。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,which led to the embarrassing situation with a theory and no the experiment in this studies.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.Through the analysis of experimental results,some practical application examples are given,deepened the understanding of the dynamic circuit,and promoted students interest in the experiment.
