Purpose & Scientific Principle
Through the phenomenon of air gap breakdown discharge in high-frequency and high-voltage environments, people can understand high-frequency and high-voltage generators. Tesla coil is a distributed parameter high-frequency series resonant transformer that can obtain high-frequency voltages of millions of volts. The principle of the traditional Tesla coil is to use a transformer to boost the ordinary voltage, and then charge the primary LC circuit resonant capacitor. When it is charged to the discharge threshold, the spark gap discharge conducts, and the primary LC circuit produces series resonance, which provides a high enough excitation power to the secondary coil. The second is equal to the frequency of the secondary LC circuit, allowing the inductance of the secondary coil and the distributed capacitance to resonate in series. At this time, the discharge terminal voltage is the highest, and lightning is seen.
How to Operate
The exhibition item consists of induction coil, booth, transformer and acrylic cover. After the exhibition item is powered on, a transformer is used to boost the normal voltage. During discharge, the energy is transferred from the transformer to the capacitor array when it is not igniting. When the capacitor array is fully charged and the voltage between the two poles reaches the voltage that breaks down the gap in the lighter, the lighter will ignite. At this time, the capacitor array forms a loop with the primary coil, completes the LC oscillation, and transfers energy to the secondary coil. Let the inductance of the secondary coil and the distributed capacitance resonate in series. At this time, the discharge terminal voltage is the highest, thus forming lightning.
The staff controls the power switch, and the audience directly watches the Tesla-like discharge phenomenon.
