Y-△降压启动控制线路的实习教学

Y-△ Starting Control Circuit Step-down Practice Teaching

本文针对QX3-13型Y-△自动启动器的实习教学,在分析原理的基础上,着重将原理图演化为实际接线图,并将控制回路与主回路分开来画,使思路更有条理,有利于学生的理解和实际安装接线。

This paper QX3-13 type automatic Y-△ starter teaching,on the basis of the principle in the analysis,focusing on the actual evolution of the schematic wiring diagrams,control circuit and main circuit and to draw apart,so that ideas are more organized,help students to understand and practical to install wiring.
