3. System composition

This device consists of a physical induction cooker, an electrical control panel, a tr*ning and assessment system and a tr*ning cabinet.

1. Actual induction cooker: adopts the popular BOKING new generation ultra-microcrystalline panel design;

2. Electrical control panel: The electrical control system of the induction cooker, including oscillation circuit, IGBT excitation circuit, PWM pulse width control circuit, synchronous circuit, VAC detection circuit, current detection circuit, VCE detection circuit, surge voltage monitoring circuit, and zero-crossing detection , Pot bottom temperature monitoring circuit, IGBT temperature monitoring circuit;

3. Practical tr*ning assessment system: The fault design mechanism adopts a concealed design. Students can eliminate faults through the troubleshooting unit according to the fault phenomenon. The assessment time and process can be fully recorded and monitored;

4. Tr*ning cabinet: The overall cabinet adopts a three-dimensional cabinet structure and is equipped with four universal wheels with brakes for easy movement and fixation. The cabinet is made of waterproof, fireproof and wear-resistant aluminum alloy material with a solid structure. At the same time, the physical object and the control panel can be combined to facilitate student operation.

5. Refrigeration , heating and home appliance m*ntenance skills teaching software: This system is in apk format and can be used on PC or mobile terminals. This system can set faults manually or automatically. This system can set faults manually through the circuit diagram. The green box selects manual setting of fault points (up to 39 fault points can be set), or the system can automatically set one random fault point, two random fault points, three random fault points, and four random fault points automatically. Settings, five random fault points are set. This system has functions such as toolbox, component library, magnifying glass, circuit diagram, etc. You can select a multimeter for detection through the toolbox, select appropriate components through the component library, and clearly understand each component through the magnifying glass. Components and circuits. This system allows students to understand the working principle and circuit structure of the motor star-delta start control circuit through the setting of faults in the motor star-delta start control circuit and various investigations.
