Appl. No.:

11/752986

Inventors:

Rush Horton, Jr. - Wytheville VA, US
Charlie H. Sarver - Rocky Gap VA, US
Curtis H. Frye - Saltville VA, US

Assignee:

ABB Technology AG - Zurich

International Classification:

H01F 7/127
H01F 5/02

US Classification:

296021, 29606, 29841, 336185, 336196

Abstract:

A method of forming a transformer coil, wherein first and second fibrous layers are provided. Each of the first and second fibrous layers includes a fabric formed from a plurality of interconnected fibers and a plurality of spacers affixed to the fabric and protruding therefrom. A conductor layer is disposed over the first fibrous layer such that a first side of the conductor layer contacts the spacers of the first fibrous layer. The second fibrous layer is disposed over the conductor layer such that a second side of the conductor layer contacts the spacers of the second fibrous layer. A resin is applied so as to cover the conductor layer and the first and second fibrous layers.

US Classification:

336185, 336205, 336206, 336196, 296021, 29606, 29841

Abstract:

A vacuum cast or “solid” transformer coil assembly and a method of manufacturing thereof are provided. A solid transformer coil assembly, according to an embodiment of the invention, includes a dielectric substrate, the coil windings provided around the substrate, and an epoxy compound encapsulating the substrate and the coil windings. The substrate is provided with raised “buttons” comprising the same epoxy material as the epoxy compound used for encapsulation. The buttons maintain a specific distance between the coil and the dielectric substrate. The buttons are arranged such that they support the windings and allow the encapsulating epoxy to flow around them flooding the entire mold without entrapping air or creating voids.

Inventors:

William Pauley - Bland VA, US
Rush Horton - Wytheville VA, US
Curtis Frye - Saltville VA, US
Charlie Sarver - Rocky Gap VA, US

International Classification:

H01F027/30

US Classification:

336185000

Abstract:

A transformer coil assembly includes a first layer having a plurality of fibers interconnected to form a fabric and a plurality of spacers. Each spacer is affixed on a first side of the spacer to the fabric and protruding from a first surface of the fabric. A second layer has a conductor in contact with at least one of the plurality of spacers on a second side of each spacer that opposes the first side. The first and second layers are covered by resin.
