磁路与电路的对偶性案例：绝缘磁芯变压器

在电气工程专业课程中，电路和磁路既有区别又相互联系。本文以绝缘磁芯变压器为例，在建立其磁路模型的基础上，利用磁路与电路之间的对偶性，采用通用、系统的方法获得了其等效电路模型。与理想变压器相比，绝缘磁芯变压器存在漏磁，且磁路含多个网孔，是学生理解电路对偶性、磁路对偶性以及磁路和电路之间对偶性的典型案例。

Example of the Duality of Magnetic and Electric Circuit: Insulated Core Transformer

In the course of electrical engineering, electric circuit and magnetic circuit are different and interrelated. In this paper, based on the magnetic circuit model of an insulated core transformer (ICT), the equivalent electric circuit model of the transformer is obtained by a general and systematic method based on the duality between the magnetic circuit and the electric circuit. Compared with the ideal transformer, the insulated core transformer has magnetic leakage, and the magnetic circuit contains multiple mesh, which is a typical case for students to understand the electric circuit duality, magnetic circuit duality, and the duality between them.
