家庭电路漏电保护器是现代家庭电路必备的元件之一,在教科书初中物理人教版八年级下册和高中物理山东科技版选修3-1中都提到了它。因为是近几年刚刚大力推广的新型元件,很多人并不能深入了解它的工作原理和工作条件。本文通过介绍漏电保护器的原理,家庭常见的两种漏电现象,漏电演示器的失败制作和成功制作,最后拓展仪器演示功能,使之能较全面演示家庭电路故障及检测。漏电保护演示器在课堂上一经演示,效果反响极好。
Home circuit leakage protector is one of the necessary components of modern home circuits, mentioned in the textbook junior high school physics PEP eighth grade and high school physics Shandong Science and Technology Elective 3-1. Because it is a new type of component that has just been vigorously promoted in recent years, many people do not have a deep understanding of its working principle and working conditions. In this paper, we introduce the principle of earth leakage protector, two common household leakage phenomena, the failure to make and produce the leakage demonstrator, and finally expand the instrument demonstration function so that it can fully demonstrate the home circuit fault and detection. Leakage protection demonstrator demonstrated in the classroom, the effect of excellent response.
