摘　　要：针对传统的电器电磁系统实验是静态实验、不能反映整个系统参数随时间变化的规律的问题,开发了基于Simulink的电磁系统动态特性仿真实验平台,建立了电路模型、磁路模型和运动方程模型。以电磁系统的气隙磁通、触头运动速度、触头接触力和电磁吸力动态变化实验为例,给出仿真实验结果。该实验可以帮助学生理解电磁机构的动态变化过程,可以有效地补充传统的电器实验内容。In view of the problem that the traditional electromagnetic system experiment of electrical apparatus is static characteristic experiment,which can’t reflect the law of the whole system parameter changing with time,a simulation experiment platform for the electromagnetic system dynamic characteristics based on Simulink is developed,and the circuit model,magnetic circuit model and motion equation model are established.By taking the experiment on the air gap flux,contact movement velocity,contact force and electromagnetic attraction dynamic variation of the electromagnetic system as an example,the simulation results are presented.This experiment can help students to master and understand the dynamic changing process of electromagnetic mechanism and can effectively supplement the traditional electrical experiment content.
