PROBLEM TO BE SOLVED: To improve magnetic characteristics of an iron core by changing a lapping method of an outer iron core out of amorphous wound iron cores having a three-phase three-leg wound iron-core structure, and to reduce lapping work man-hours. SOLUTION: The amorphous wound iron-core transformer has a three-phase three-leg wound iron-core structure comprising two inner iron cores 2 where one sides of leg sections inserted into an interlinking coil 1 are adjacently disposed, and an outer iron core 3 surrounding the outer peripheries of the inner iron cores 2, wherein the wound iron core is formed in a rectangular shape by laminating thin amorphous magnetic strips on one another to include a pair of leg sections, a pair of yoke sections, and a window section surrounded by the leg sections and the yoke sections. The outer iron core 3 has a lap joint part over the entire linear sections of the yoke sections. COPYRIGHT: (C)2011,JPO&INPIT |
