RADIAL DROP WINDING FOR OPEN-WOUND MEDIUM VOLTAGE DRY TYPE TRANSFORMERS WITH IMPROVED SUPPORT STRUCTURE

摘要

A method provides a radial drop winding for an open wound transformer. A plurality of non-electrically conductive posts are arranged to define an interior space. Each post is of generally L-shape having a main body and a leg extending from a bottom end of the main body. During an open winding process, conductive wire is dropped to build up lengthwise along the posts to define at least one generally cylindrical winding segment supported by the legs of the posts.

1. A method of providing a radial drop winding for an open wound transformer, the method comprising the steps of:
arranging a plurality of non-electrically conductive posts to define an interior space, each post being of generally L-shape having a main body and a leg extending from a bottom end of the main body, and during an open winding process, dropping conductive wire to build up lengthwise along the posts to define at least one generally cylindrical winding segment supported by the legs of the posts.
