高电压技术中流注放电的科研反哺教学研究

针对《高电压技术》课程中流注放电的教学难点,本文从科研反哺教学的角度出发,介绍了一种具有高重复性的新流注放电形式-大气压等离子体射流,并采用ICCD相机拍摄它的高速传播过程,实现了流注放电教学直观形象化和定量化。从教学内容更新、教学手段丰富、课程设置优化、教学考核与反馈等多个教学环节落实流注放电的科研反哺教学方法,并取得了较好的教学效果,为该课程其他知识点的教学质量提升提供参考。

Study on the teaching of streamer discharge in high voltage technology with the feedback of its scientific research

To overcome the teaching difficulties of streamer discharge in the course of "High Voltage Technology", this paper introduces a new type of streamer discharge with high repeatability - atmospheric cold plasma jet from the perspective of teaching course, and studies the high-speed propagation process of the plasma jet with an ICCD camera. This realizes the visualization and quantification of the teaching of streamer discharge. From the aspects of the teaching content updating, the teaching methods, the curriculum optimization, the course assessment and feedback, the latest scientific research results of streamer discharge are integrated into the teaching process, resulting in a good evaluation of the course teaching. This study provides a reference for the improvement of teaching quality in other knowledge points of the course.
