Abstract

Invention herewith described refers to a wound delta magnetic core of a three-phase transformer station where one of three identical rectangular round coils (figure 1) is made of seven steps wound one over the other with five different widths of strips of sheet of the transfromer station sheet. The first step is wound even and the remaining ones under the shearing angle of each layer of the transformer station sheet by the angle of 30°. Thickness of the wounded layers are designed so that the tips of flat sloped steps maximally reach the circumscribed circle while the bottoms lie in a diameter of the circle the direction of which is by 30° dislocated compared to the normal axis of the coil. Three such coils are coupled by triangular arranging of flat sides of the coils (figure 3) and the joints are fixed in a polyglass stripe wound around it.
