【摘要】 利用自制的三相交流电路实验装置,我们在传统的三相交流电路电压、电流等的测量之外,增加了利用示波器直接观测三相电波形以及交流电动机等实验内容,有助于同学们更直观地理解三相电特性。由于强电实验的特殊性,我们在市电接入和实验电路之间加入了接触器保护装置以及手控开关,并在实验中规定同学必须遵守"单人单手"操作规则,多重安全设计确保了实验安全。结合生产生活实际,我们还设计了电力传输,生活中的三相电常识,安全用电知识等实验讨论内容,并以我国在特高压输电领域的发展历程为切入点,进行"课程思政"的教学,增强同学们的爱国主义观念。更多还原

【Abstract】 Using the self-made three phase AC circuit experimental device, we add the experiment content of using oscilloscope to directly observe the three-phase electric waveform and AC motor in addition to the traditional experiment content of measuring voltage and current of three-phase AC circuit. For the safety of the experiment, we add a contactor protection device and a manual switch between the commercial circuit and the experimental circuit, and require the students to abide by the operating rules of “single person, single hand” in the experiment. Combined with the reality, we also designed the experimental discussion content of power transmission, three-phase electricity knowledge in life, knowledge of using electricity safely and so on. Taking the development process of China’s UHV transmission field as the breakthrough point, we carried out the ideological and political teaching in course to enhance students’ patriotism.更多还原
