（1）Training objectives

Watch the demonstration project and experience it using a simulated person. When the simulated person's face is not wearing a protective mask, the short-circuit arc can cause severe burns to the simulated person's face; When the simulated person wears a protective face mask, the short-circuit arc does not cause significant harm to the simulated person.

When the device is used for live work, is a protective face mask worn? Let the students know the importance of correct operation during electrical work and the importance of wearing a protective face mask during work.

（2）Equipment composition: power supply and control power supply, power protection module, data acquisition module, arc burn body sensing platform, simulator, computer, test display module, LCD TV, etc.

（3）Project Function

Functional requirements:

1Simulation demonstration function: Simulate and display the degree of damage caused by electric arcs to the simulated human face under different protection states;

2Overcurrent protection function: When the short-circuit current of the line is too high, the power supply can be cut off to protect the equipment;

3Time control function: When the short circuit of the circuit exceeds a certain time, it can automatically disconnect the power supply;

4Play demonstration function: Play accident scenes of arc burns to3DThe form of animation displays knowledge related to the generation and harm of electric arcs.
