Product Introduction
Electric furnace transformer is a power supply equipment that is compatible with electric furnaces.
It has more stringent requirements than power transformers in terms of electricity, magnetism, heat, and machinery, and must comply with the operating processes and load characteristics of various electric furnaces to meet the conditions of convenient use, energy conservation, and emission reduction for users.

characteristic
1. Wide voltage regulation range, secondary voltage is regulated by grade difference, suitable for the process requirements of electric arc furnace steelmaking
2. High voltage is not limited by the level of switch insulation, and high voltage (such as 110KV) can be reduced to low voltage by 100 connections, eliminating the need for intermediate substations and saving more than 30% of investment.
3. It is convenient to choose the appropriate voltage level of on load tap changer, which is economical and safe.
4. Compensation capacitors can be connected to improve the power factor of the network.
5. The main transformer operates under constant magnetic flux density, making full use of materials and achieving good economic efficiency.
6. Adopt technical measures such as in-phase reverse well coupling, electric or magnetic shielding, and transposed wires to reduce losses and improve efficiency.
7. Adopting a separate voltage regulating coil with good ampere turn balance, it increases its ability to withstand short circuits and has high reliability.
Taking the 31500/110 electric arc furnace steelmaking transformer as an example, its load loss, no-load loss, and no-load current have decreased by 13%, 17%, and 26% respectively compared to the original product, making it a truly innovative energy-saving and emission reducing product.
