【摘要】 “高电压技术”课程是电气工程及其自动化专业的必修课程之一，涉及较多的电击穿、流注放电、绝缘等课堂讲解和实验课程难以理解和观察的概念和理论。采用数字化仿真软件COMSOL对球体之间的电击穿、氮中流注放电现象进行建模分析和形象展示，并将其融入课堂教学，可促进学生对高电压击穿、电晕等原理及其过程的理解。课堂教学反馈显示，本科生对于高电压技术课程学习的积极性和效果显著提高。更多还原

【Abstract】 High voltage technology is one of the required courses for electrical engineering and automation majors, which involves many concepts and theories difficult to understand and observe in classroom lectures and experimental courses, such as electric breakdown, stream discharge and insulation. In this paper, digital simulation software COMSOL is used to model, analyze and display the electric breakdown between spheres and the flow discharge phenomenon in nitrogen, and integrated into classroom teaching, so as to promote students’ understanding of the principle process of high-voltage breakdown and corona. The feedback of classroom teaching shows that undergraduates’ enthusiasm and effectiveness of high voltage technology courses have improved significantly.更多还原
