Claims

[Scope of utility model registration request]

(1) A wound iron core for a transformer, which is formed by winding an electromagnetic steel plate, wherein the electromagnetic steel plate is formed into a long rectangular shape with a tapered substantially trapezoidal shape protruding from one short side.

(2) The wound iron core for a transformer according to claim 1, wherein the electromagnetic steel sheet includes a rectangular electromagnetic steel sheet piece and a substantially trapezoidal electromagnetic steel sheet piece that are connected and fixed.

(3) The above-mentioned wound iron core is a combination iron core with a few (two) wound magnetic steel sheets, and the wound iron core with magnetic steel sheets is installed in a straight line in contact with the outer peripheral wall. Featured utility model registration claim Paragraph 1 or 2
Wound iron core for transformer as described in section.

(4) The wound iron core for a transformer according to claim 3, wherein the combined iron core is provided with a shielding iron core on its outer periphery.

(5) The wound iron core for a transformer according to claim 4, wherein the combination iron core is provided with a mounting fitting that comes into contact with the shielding iron core.
