Claims

[Scope of utility model registration request]

A transformer body is constructed by winding a coil around the legs of a wound iron core, and the outer surface of the wound iron core is surrounded by a container-shaped frame, in which the upper surface of the frame is cut and raised at a plurality of places. A wound core type dry transformer characterized in that cooling holes are provided in a distributed manner by machining, and the cut and raised pieces produced by the cutting and raising process are bent above the corresponding cooling holes so as to cover them. vessel.
