Study on Water-Cooled Capacitors Used in Medium Frequency Furnaces

As an efficient metal smelting equipment, the medium frequency furnace plays an important role in industrial production. The water-cooled capacitor plays a key role in the medium frequency furnace, and its performance directly affects the working efficiency and stability of the medium frequency furnace.

Ⅰ. Working principle of water-cooled capacitor in medium frequency furnace

In the medium frequency furnace, the water-cooled capacitor and the induction coil together form a resonant circuit. When the medium frequency current passing through the induction coil generates a changing magnetic field, eddy currents are induced in the metal charge, thereby heating the charge. The water-cooled capacitor adjusts the frequency and power factor of the resonant circuit by storing and releasing electrical energy, so that the medium frequency furnace can work in the best state.
