Energy-saving Effect of IGBT Series Induction Furnace

The energy-saving IGBT transistor intermediate frequency power supply saves 25% - 28% more energy than the traditional thyristor intermediate frequency power supply. The key reasons for energy saving are as follows:

The inverter voltage is high, the current is small, and the line loss is small. This part can save 15% - 18% energy. The inverter voltage of the energy-saving IGBT transistor intermediate frequency power supply is 2800V, while the inverter voltage of the traditional thyristor intermediate frequency power supply is only 750V, the current is nearly 4 times smaller, and the line loss is greatly reduced;

The power factor is high, the power factor is always greater than 0.97, and the reactive power loss is small. This part saves 3% - 5% energy than the thyristor intermediate frequency power supply. Because the energy-saving IGBT transistor intermediate frequency power supply adopts the semi-controllable rectification method, and the rectification part does not adjust the thyristor conduction angle, the power factor throughout the working process has been greater than 0.97, and the reactive power loss is small.

Less heat loss at the furnace mouth: because the energy-saving IGBT transistor intermediate frequency power supply is 20 minutes faster than the same power thyristor intermediate frequency power supply, the heat loss at the furnace mouth within 20 minutes can account for 3% of the whole process, so this part can save about 3% energy than the thyristor intermediate frequency power supply.
