して成る箔状巻線を有する箔巻変圧器において、金属箔
にはその巻回層ζ゛とに異なった幅の幅広部と幅狭部と
が形成され、幅広部の両端には電界緩和用の折曲部が一
体に形成され、幅狭部はこの幅広部より両端の折曲部の
分だけ幅の狭いものであり、且つこの幅狭部が幅広部の
折曲部側の表面に絶縁材を介して重ね合わされた状態で
巻回されていることを特徴とする箔巻変圧器。In a foil-wound transformer having a foil winding formed by winding a metal foil around the legs of an iron core with a sheet-like insulating material interposed therebetween, the metal foil has wide portions with different widths in the winding layer ζ゛. and a narrow portion are formed, and bent portions for mitigating the electric field are integrally formed at both ends of the wide portion, and the narrow portion is narrower than the wide portion by the amount of the bent portions at both ends. A foil-wound transformer characterized in that the narrow portion is wound so as to overlap the surface of the wide portion on the bent portion side with an insulating material interposed therebetween.
