PURPOSE:To contrive to form in a small type and to reduce weight of a tank for electric induction apparatus provided with a magnetic shield by a mthod wherein the side of the magnetic shield facing to a winding is made to form a curved surface type and is formed in a loop type, and the magnetic shield is fixed with fixing members fixed to the side walls. CONSTITUTION:The fixing members to fix the magnetic shield 8 to the side wall of tank is fixed by welding an endless conductive supporting frame formed to have circular section and formed as to have no angular part to support the magnetic shield without using mounting base, metal fixtue and fitting bolt as usual. Accordingly the magnetic shield exerts no adverse influence on insulation between the winding, the distance between the winding and the magnetic shield can be shortened, and the transformer can be formed in a small type, and weight thereof can be reduced. |
