COIL BUS FOR A TRANSFORMER AND A METHOD OF MANUFACTURING THE SAME

摘要

The invention is directed to a transformer and a method of manufacturing the same. The transformer has high and low voltage coils mounted to legs of a core. Each low voltage coil includes, conductor sheeting (40) having opposing first and second ends and opposing first (92) and second (94) side edges. A pair of coil bus bars (42) is provided for each low voltage coil. Each coil bus bar (42) has first and second portions, wherein the first portion has a width (W1) that is more than one and a half times greater than a width (W2) of the second portion. Each coil bus bar (42) is secured to the conductor sheeting (40) of its low voltage coil such that the first portion of the coil bus bar is disposed at the first side edge (92) of the conductor sheeting and the second portion of the coil bus bar is disposed at the second side edge (94) of the conductor sheeting.
