Claims

[Scope of utility model registration request]

In a product in which live parts such as outlet terminals and intermediate tap terminals protruding from the outer surface of resin molded coils of each phase arranged on an iron core are covered with an insulating cover plate, the coil At the top and bottom of the outer surface, there are resin U-shaped mounting seats with bent pieces on both sides and a bridging part in the center, and the bridging part is brought into close contact with the outer surface of the coil. A longitudinal thin resin plate is placed on the surface of the bridge portion of the mounting seat so as to straddle the bridge portion and the outer surface of the coil, and the portion of the thin plate protruding from the bridge portion is placed outside the coil. A roving material impregnated with a thermosetting resin is wrapped around the outer surface of the coil, and the mounting seat is attached to the coil using a thin plate.The resin impregnated in the roving material is heated and solidified to attach the mounting seat to the coil. A live part protection device for a molded transformer, which is integrally fixed to the mounting seat, and a pair of vertically elongated cover plates formed in an L shape are arranged in a U-shape on the bent piece of the mounting seat.
