摘　　要：三相异步电动机控制电路故障排查是实验教学的重难点。实物教学存在故障设计排查成本高、强电操作危险大、电路分析验证难等弊端,且商业电气设计仿真软件又不适合学生入门学习。因此,设计船用电机启动控制电路故障诊断虚拟仿真实验。逼真呈现船舶管系运行场景、电控柜及电器元件组成,着重还原真实故障电路状态与排查过程,实现故障随机模拟与任意节点电压电阻自主测量等。该虚拟仿真实验已成功应用到本科实验教学,起到了良好的实验教学效果。Troubleshooting of a three-phase asynchronous motor’s control circuit is a critical knowledge point for experimental teaching.However,object teaching faces with challenges of high cost of fault design and detection,high risk of high voltage at live working,and hard verification of circuit analysis.Besides,commercial electrical design simulation software is not suitable for students to learn as elementary course.Therefore,a virtual simulation experiment of the fault diagnosis of the ship motor’s control circuit is designed.It could simulate real piping system working scenario,control cabinet and electrical parts in a three-dimensional virtual reality model.By restoring running status and troubleshooting process of the circuit under faults,students could experience random simulation of faults,and measure voltage and resistance of any node.The virtual simulation experiment designed in this paper has been successfully applied to undergraduate experimental teaching,which received excellent teaching outcomes.
