10. Innovative design module (one set per batch, from the same manufacturer as the electrical and electronic lab bench)
1) Simulated three-phase AC experimental model: This model simulates a three-phase AC power source using low-voltage DC power. The output three-phase AC power has adjustable voltage amplitude and phase difference, ensuring stability, reliability, safety, and energy conservation. This effectively avoids significant errors in experimental results caused by the uncertainty of the three-phase load of the entire power grid system (the three-phase load is random at every moment, resulting in unbalanced three-phase loads) and the non-zero internal resistance of the power supply system, which can lead to unbalanced and unstable three-phase power. This can affect experimental teaching efficiency and results. It conveniently observes the changes in neutral current caused by the three-phase voltage amplitude or phase difference changing from balanced to unbalanced, thereby deepening students’ understanding of three-phase electricity and increasing their learning interest. Using a load resistor in parallel with a light-emitting diode display circuit as each phase of the three-phase load ensures high load accuracy, energy conservation, long life, and enhanced personal safety.
