The difference between special transformer for induction melting furnace and ordinary transformer

The transformer dedicated to the induction melting furnace is a rectifier transformer. The reason is that the impedance of the rectifier transformer is higher than that of ordinary transformers and the harmonics are small. Transformers s9 and S11 are mainly for civilian use. The difference in voltage. The induction melting furnace uses industrial electricity, the 380V ordinary transformer is civil electricity, and 220V. Generally speaking, the principle and structure of the two transformers are not much different, but the impedance requirements are somewhat different. In addition, the induction melting furnace transformer is high. Add grounding shield between low voltage coils.

For the special transformer used in the induction melting furnace, it is necessary to accurately calculate the parameters in the manufacturing materials, select high-quality, high-permeability, low-loss, high-quality silicon steel sheets to manufacture cores and wires, and scientifically determine the copper-to-iron ratio. The manufacturing materials ensure that the transformer has low no-load loss and low noise performance. Through the “open source and throttling” method, the heat dissipation of the transformer and the effective control of the current are increased, so that the stable and efficient operation of the transformer can be ensured.
