International Classification:

H02K009/00
H02K009/20

US Classification:

310/052000, 310/054000

Abstract:

A header () for use with an inner-cooled half coil () in a stator phase winding of an electrical generator. The half coil may include a stack of cooling tubes () with a first stack of conductive strands () adjacent a first side of the stack of cooling tubes and a second stack of conductive strands () adjacent a second side of the stack of cooling tubes. A header () is conductively bonded () by brazing to each strand of the first stack of conductive strands () and to each strand of the second stack of conductive strands () for consolidating the first and second stacks of conductive strands. A means () for allowing a coolant to flow through the header () may be provided to allow coolant to flow through the stack of cooling tubes (). The means () for allowing coolant to flow through the header () may include a plurality of apertures () that are aligned with respective ones of the stack of cooling tubes () for inspecting the cooling tubes through the apertures. Conductive connectors () may be attached to and removed from the header without affecting the consolidation of the conductive strands.

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H02K 346

US Classification:

310260

Abstract:

A filler material for supporting the coil end portions at the diamond area of a dynamoelectric machine consists of a resin filler disposed in the vent areas between adjacent coil end portions and a plurality of spacer blocks disposed in the filler. The spacer blocks have a sufficient volume and coefficient of thermal expansion to prevent excessive build up of temperature during curing of the resin and to decrease the overall coefficient of thermal expansion of the filler material and adjust the thermal expansion characteristics of the filler material so that such characteristics more closely match the thermal expansion characteristics of the coils themselves. The resin filler comprises an epoxy resin and the blocks, which have a generally orthogonal shape, are constructed of a laminated fiber glass material. A bead of resinous material is provided at the edges of the planar surfaces of the orthogonally shaped blocks to prevent abrasive contact between the blocks and the adjacent coil end portions.

International Classification:

H02K 1100

US Classification:

310 71

Abstract:

A solid series connector for electrically connecting a first half-coil to a second half-coil in a stator phase winding includes first and second solid conductor members which are fixedly electrically connected at both ends to groups of conductive strands in the respective half-coils. The connector is much less labor-intensive to install than the group transposition connections used in the past, is more rugged and durable under high temperatures and stresses, and is relatively compact. A second embodiment of the invention is a solid phase connector that incorporates many of the novel features in the solid series connector. A novel method of preparing a conductive strand group for connection to such connectors is also claimed.

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H02K 346

US Classification:

310260

Abstract:

A mechanical clamping assembly and the method of its application for use on the stator end windings of large steam turbine generators is provided that can be fit in the mid-involute region of the end winding, including any existing machines as may be in use in the field as well as in original manufacture. The invention maintains pressure contact between coils and strain blocks and eliminates the freedom of the coils to vibrate relative to the total end basket assembly. The method comprises steps of forming a loop of impregnated banding material that extends through apertures of support blocks that span a pair of adjacent top and bottom coils, inserting pins in the ends of the loop, twisting a pin, curing the banding material, pulling on a pin to pretension the banding and shimming the pulled pin so that upon its release a tight assembly is provided.

Appl. No.:

Inventors:

Henry M. Holly - Winter Park FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H02K 350

US Classification:

340260

Abstract:

A filler material for supporting the coil end portions at the diamond area of a dynamoelectric machine comprises a resin filler disposed in the vent areas defined between opposed sides of spaced coil end portions at the diamond area, and an elongated, transversely corrugated, longitudinally flexible, sheet-like spacer element disposed within the filler at each vent area. The spacer element is positioned to extend along the respective vent area, with opposite faces thereof facing the sides of the coil end portions on either side of the vent area. The spacer element has a sufficient surface area in contact with the filler as a result of the corrugations of the spacer element, to retard sagging of the filler during installation and curing. The corrugations of the spacer element are generally rectangular in shape so that the element comprises a series of panels disposed in general parallelism to the sides of the corresponding coil end portions.

Inventors:

Henry M. Holly - Winter Park FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H02K 346

US Classification:

310260

Abstract:

A biased securement system for the end winding conductors of a turbine generator includes a support ring with a biased wedge system located between the end windings to compress them in both a radial and circumferential direction. A triangular shaped wedge is secured to the support ring between a pair of confronting spacer blocks having angular surfaces converging in the direction of the support ring. Belleville washers are disposed in a recess in one of the spacer blocks, with a slide plate therebetween which is held in place by a lock plate to retain the same in position.
