Pay attention to the power consumption of important parts such as quenching transformers. An example is the same workpiece and inductor experiment at the same power supply, and a transformer takes 120KW, reaching temperature, while another is only 90KW. This instance reminds us that the difference in electricity consumption of important parts must be carefully selected, the efficiency and standard of the quenching transformer must pay attention to, the iron loss, copper loss, and magnetic magnetization of the transformer must strict requirements, and should be International horizontal lack. French CELEM's MT series quenching transformer has been used in layered copper sheets, with a conventional copper tube, with a frequency range of 90% to 95%, and the power consumption of the quenching transformer has an important position in the induction device system. It should be continuously improved.
