Abstract

PURPOSE: When E-shaped and I-shaped steel plates are laminated to form a transformer core, to constitute the outermost layer by block-type steel plates by bonding beforehand two or more steel plates thereby to prevent deformation of the E-shaped core and evade the lowering of magnetic characteristics thereof.
CONSTITUTION: An I-shaped core 8 formed by laminating I-steel plates 7 into a plate shape and an E-shaped core 4 formed by laminating E-steel plates 1 into an angle shape are combined and clamped by means of support metal fittings 3 thereby to form a transformer core. In this case, to the both outermost sides of the I-shaped core there is fitted steel plate 10 formed by bonding two or more E-steel plates 1 into a block shape, and at both sides of the E-shaped iron core 4 there is provided a steel plate 11 formed by bonding two or more E-steel plates 1 into a block shaped. Both cores are clamped through these steel plates by means of support metal fittings 3. By this procedure, no deformation occurs in the main leg 5 in the center of the E-shaped core 4, and the E-shaped core and I-shaped core are can be laminated precisely, thus no lowering of the magnetic characteristic being produced.
