剩余电流保护器（RCD）是电气类专业“工厂供电”课程的教学重点。为提高教学效果，从剩余电流定义、零序电流互感器、广义基尔霍夫电流定律等三个方面进行探讨。实践表明，这些教学探讨能使学生有效地理解和掌握RCD的基本知识与技能，为从事RCD的选用、装调、运行与维护等实际工作打下牢固基础。
剩餘電流保護器（RCD）是電氣類專業“工廠供電”課程的教學重點。為提高教學效果，從剩餘電流定義、零序電流互感器、廣義基爾霍伕電流定律等三箇方麵進行探討。實踐錶明，這些教學探討能使學生有效地理解和掌握RCD的基本知識與技能，為從事RCD的選用、裝調、運行與維護等實際工作打下牢固基礎。

Residual current protective device (RCD), which is a sub-course of “factory power supply”of electrical specialty, is seriously significant but challenging. This paper presents an exploration in order to improve the teaching effect, and it involves three aspects of residual current definition, zero sequence current transformer and general kirchhoff's current law. The practice proves that students can understand and grasp the basic knowledge and skills of RCD effectively, establishing a good foundation for further work of selection, assembling adjusting installation, operation and maintenance of RCD.
