WOUND IRON CORE FOR STATIC APPARATUS, AMORPHOUS TRANSFORMER AND COIL WINDING FRAME FOR TRANSFORMER

WIPO Patent Application WO/2010/026898

A1

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.
