  • Rolled iron core traction transformer
    Patent number: 9812252
    Abstract: A rolled iron core traction transformer, comprising an iron core (1); the iron core (1) is formed by splicing two symmetrical annealed iron-core closed single frames (1-1); each iron-core closed single frame (1-1) is formed by sequentially coiling continuous silicon steel sheets; the iron-core closed single frame (1-1) has two iron core column single bodies (1-1-1) having approximately semicircular cross sections; the iron core (1) has two iron core columns (1-2) thereon spliced by the iron core column single bodies (1-1-1) and having approximately circular cross sections; each iron core column (1-2) is sequentially provided with a low-voltage T winding (6), a low-voltage F winding (5) and a high-voltage winding (4) thereon from inside to outside; two sides of each high-voltage winding (4) are respectively provided with a first tapping area and a second tapping area; the first tapping area is provided with low-voltage side high-voltage tapping outgoing lines (16); the second lapping area is provided with high
