    摘要: A technology for manufacturing a transformer core with laminated structure draws the magnetic sheet materials in parallel from plural winding bodies around which the magnetic sheet material is wound like hoop, cuts the materials at predetermined positions substantially simultaneously to form plural magnetic sheet materials each with a different length, forms a block-shaped laminate by laminating the plural magnetic sheet materials in the order of length, and further laminates the block-shaped laminates in the order of length. The resultant laminate formed by laminating the plural block-shaped laminates are formed into an annular structure so that the longer block-shaped laminate is wound on the outer circumference of the winding core and the shorter block-shaped laminate is wound on the inner circumference, and abutting and overlapping both ends of the respective magnetic sheet materials so that the abutting or the overlapped portions are located at circumferentially different positions between the adjoining layers of the magnetic materials.

    摘要: An apparatus for manufacturing a transformer core includes a drawing which draws magnetic sheet materials in parallel from winding bodies. A cutter cuts the sheet materials at predetermined positions substantially simultaneously to form sheets each with a different length. An overlapping unit forms a block-shaped laminate by laminating the cut magnetic sheet materials in length and forms a resultant laminate by laminating the formed block-shaped laminates. An annulation unit forms an annular structure of the resultant laminate so that the longer block-shaped laminate forms the outer annular portion and the shorter block-shaped laminate forms the inner annular portion. Both ends of the magnetic sheet materials are abutted or overlapped to locate the abutted or overlapped portions at annularly different positions between adjoining layers of the magnetic sheet materials. A control unit controls the drawing unit, cutter and overlapping unit.

    摘要: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core. A ring-shaped iron core is configured such that a plurality of block-like laminated members, which are each formed by laminating a plurality of strip-like amorphous material thin plates, are laminated and formed into a ring shape and a sheet-like non-magnetic insulation material is arranged between the n-th (n: an integer of two or more) layer of the ring-shaped block-like laminated members from the most inner circumference side and the (n+1)-th layer of the ring-shaped block-like laminated members from the most inner circumference side.
