Abstract
A magnetic core arrangement for shell-form power transformers. A main core structure is divided into two core portions by a gap which separates the core laminations. Two shielding cores are located on each side of the main core. Double-webbed beams are positioned underneath the main and shielding cores to support these cores from the transformer tank. One web of a beam extends into part of the gap between the main core portions. The other web of the beam is located between the outermost main core portion and one of the shielding cores. The gap in the main core structure improves the cooling of the magnetic laminations and the web members of the beam enhance the support for the core laminations.
