Energy Saving Measures For Transformers

(1) Selecting high-quality materials to manufacture transformers
Transformers change the network voltage through electromagnetic induction, mainly made of silicon steel sheets and electromagnetic wires. The quality of these two materials directly affects the loss characteristics of the transformer. The loss formed by the iron core of a transformer during operation is commonly referred to as no-load loss. The loss value is constant and has little to do with the load rate of the transformer, making it inevitable. But the quality of magnetic materials can change the magnitude of their losses. The first generation of energy-saving transformers selected high-quality Q11 Q10 cold-rolled grain oriented silicon steel sheets, eliminating hot-rolled D44 and other silicon steel sheets, combined with structural design improvements to reduce no-load torsional wear by 40%.
(2) Optimize design and improve processes
Improving the loss characteristics of transformers through structural design and manufacturing processes is the main research topic for manufacturers. The application of electronic computers in transformer design has opened up broad prospects for design work. Under the ideal copper (electromagnetic wire) to iron (silicon steel sheet) ratio, the design goal is to minimize losses and copper iron consumption. Intersection of high-quality materials and optimized design curves at one point to achieve optimal results. The change of the iron core structure from direct seams to semi straight, semi oblique, and fully oblique seams is a breakthrough improvement in structural design, which can relax the magnetic conductivity direction of grain oriented silicon steel sheets (Q10, Q11, which are widely used nowadays) in the iron core seam area and reduce no-load losses.
