圧器。 In a sheet-wound transformer that uses a sheet-like winding formed by overlapping and winding a metal sheet and an insulating sheet, and is equipped with a shield ring at the end of the winding for mitigating the electric field, the shield ring is placed at the lowest point of the electric field. In addition to having a structure having a plurality of supporting pieces,
A conductive layer or a semiconducting layer is formed in the insulating layer constituting the main insulating part of the sheet winding so as to apply almost the same potential to the shield ring as the end of the winding through capacitive coupling. sheet-wound transformer.
