変圧器、変圧器鉄心の製造装置及び製造方法

Document Type and Number:

Japanese Patent JP5867982

Kind Code:

B2

Abstract:

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.
