COOLING STRUCTURE OF WINDING

摘要

PROBLEM TO BE SOLVED: To provide a transformer winding structure which introduces cooling medium in a winding lower part to a winding upper part without receiving heat generation of the winding lower part in order to effectively cool the winding upper part. SOLUTION: This cooling structure consists of oil stoppers 9 which are arranged in the respective disks so as to separate a cooling path of a winding 1 into two parts for a winding upper part and for a winding lower part, for effectively cooling the upper part of the winding 1, cooling medium converting barriers 2 arranged in perpendicular cooling paths 4 inside and outside the winding, and perpendicular cooling paths 8 in winding arranged in the respective disks.
