ABSTRACT:
A power transformer is formed of a pair of cores having wiring storage portions, at least one primary winding formed of a spirally wound flat ring having a pair of primary leading portions, at least one secondary winding formed of a flat plate, at least one spacer interposed between the flat ring and the flat plate, and an insulation member mounted in the wiring storage portions of the cores. The flat ring, flat plate and at least one spacer for insulating the flat ring and the flat plate are housed in the insulation member. The insulation member has an opening for allowing the primary leading portions to pass therethrough. In order to insulate the primary leading portions from burrs of the secondary winding, a protrusion may be formed on an outer periphery of the spacer to be located under the primary leading portions, or a cut-out portion may be formed in the flat plate.
