四步法绘制三相变压器高压绕组线电动势

A Study on the Application of the Four-Step Method in the Drawing of the Wire EMF of the High-Voltage Winding of the Three-Phase Transformer

在传统绘制绕组相量图方法的基础上,结合变压器绕组的连接方式,提出一种简单易懂的高压绕组线电动势的绘制方法,能快速教会学生正确绘制三相变压器高压绕组线电动势。

Based on the traditional way of drawing the phasor diagram of the winding,in combination with the connecting mode of the winding of the transformer,this paper introduces a simple and easy-to-understand method which can help students correctly draw the wire EMF of of the high-voltage winding of the three-phase transformer.
