MOLDED POLE TRANSFORMER FOR OUTDOOR USE CAPABLE OF REDUCING SIZE OF TRANSFORMER

摘要

PURPOSE: A molded pole transformer is provided to reduce the size of the transformer by integrally molding a high voltage coil and a low voltage coil into a single unit. CONSTITUTION: A molded pole transformer comprises an iron core(203) for forming a magnetic path; a high voltage coil(201) and a low voltage coil(202) concentrically disposed in the iron core; and a resin structure molded to cover the high voltage coil and the low voltage coil. The high voltage coil and the low voltage coil are integrally molded, and cooling air ducts(204h,204k,204m) are interposed between the high voltage coil and the low voltage coil.
