How to reduce the loss caused by the transformer of the induction melting furnace?

The output voltage of the side is between 660V and 800V. When the output voltage is 650V and the output power is constant, the working current of the induction melting furnace will be reduced to 0.6 times compared with the original 380V, and the copper loss will be reduced to 1/3 of the original, reducing the heat of the transformer itself. Loss, the resistance of the transformer coil will also increase when working at high temperatures, the burden on the heat dissipation system will be reduced, the operating temperature of the system will be reduced, and the energy-saving effect is very obvious. To

In addition, when the induction melting furnace has a long no-load time, it can be switched off to stop the dry operation of the transformer, which is also conducive to energy saving and consumption reduction.
