Claims

[Scope of utility model registration request]

In a wound core type dry type transformer in which a coil is wound around a leg of a wound core whose outer surface is surrounded by a container-like frame, there is an insulation between one side wall of the upper frame of the frame and the wound core. Along with intervening things,
A wound iron core dry type transformer, characterized in that an exhaust hole is provided on the upper surface of the upper frame, eccentrically from the center toward the insulator.
