NON-LINEAR TRANSFORMER AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A three-phase non-linear transformer and a method of constructing the same. The non-linear transformer includes a non-linear ferromagnetic core having a plurality of frames, each of which has a closed or substantially closed periphery. The frames are arranged to form at least three legs. A low voltage winding is formed around each leg and a high voltage winding is formed around each low voltage winding. Each high voltage winding includes a plurality of serially-connected disc windings. Each of the disc windings is formed of alternating concentric layers of a conductor strip and an insulation strip, wherein the conductor strip having a width to thickness ratio of greater than 10:1. A casing encapsulates each pair of high voltage and low voltage windings. The casing is formed using a mold at least partially formed by a winding device used to wind the high voltage and low voltage windings. |
