ABSTRACT:This paper is from the development history of transformer, synthesized the approximate development and currently the manufacturing level of the transformer in our country, analyze the margin and development direction of transformer in our country and carry on theories analysis to each part. Then we begin to investigate how to carry out low- exhaust, high-efficient and low-noise to the transformer, and carry on the theories analysis to 8000KVA immerse type transformer which include the design of the iron heart project and winding project and the electromagnetism calculating. Finally, according to the electric voltage size and craft method, we choose the winding project, and carry on temperature ---increased calculation, choose the form of heat dissipation. With low cost design a transformer of high performance and draw the plotting of each engineering diagram part.
