Filed:

May 12, 1976

Appl. No.:

5/685466

Inventors:

Jeffry R. Meyer - Penn Hills Township, Allegheny County PA
Robert L. Hess - North Versailles PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01H 3382
H01H 930

US Classification:

200148A

Abstract:

An improved modular, puffer-type circuit-interrupting unit is provided capable of its own independent support, and adaptable for use, either as a singular modular unit, or when used with a plurality of similar units, constituting a conjointly-acting group of serially related puffer-units suitable for the higher-voltage applications. The modular puffer-unit of the instant invention is capable of independent support, and is adaptable for very simple straight-line actuating movement, for not only causing contact separation, but also a simultaneous compression of the utilized gas to a pressurized state for gas ejection into the established arc for rapid arc extinction thereof. A novel feature of the instant invention is the utilization of a side insulating support baffle plate, which not only provides the desirable independent support for the stationary contact structure of the modular puffer-unit, but, additionally, serves as a baffle plate to prevent the lateral dispersion of the emanated hot arc gases from reaching the side tank wall, and thereby causing voltage flash-over.

International Classification:

H01H 3382

US Classification:

200144AP

Abstract:

An improved, multi-function, stationary-contact-and-voltage-shield structure is provided for a high-voltage gas-puffer-type circuit-interrupter, in which the surrounding metallic shield provides a smooth, low-gradient voltage shape, collecting and cooling the dispersed hot arced gases, generated during the interrupting operation at the arc, by the provision of selectively-located venting cooling port holes provided in the metallic shield structure and also in the stationary contact structure. The arrangement of the enveloped stationary contact and surrounding main stationary contact fingers, together with the outer, encompassing vented metallic shield arrangement is such as to provide an improved highly-efficient single-pressure puffer-type high-voltage circuit-interrupter.

Robert A. Hess - Altadena CA

Assignee:

Stainless Steel Products, Inc. - Burbank CA

International Classification:

F16L 2704

US Classification:

285226

Abstract:

An aircraft engine bleed air ducting system including at least one universal ball joint within said ducting, said joint fitted with an annular bearing seal to seal and reduce the coefficient of friction between moving parts in said joint during angulation of said joint. The annular bearing seal includes a reinforcement wire surrounded by a graphite composition, which composition is in direct contact with parts of said bearing seal and said wire aids in prevention of deformation of said bearing seal.

Appl. No.:

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01H 3302
H01H 3324
H01H 3388

US Classification:

200148R

Abstract:

An improved compressed-gas puffer-type circuit-interrupter is provided having improved supporting, shielding and assembly features for making ready provision for a separate bench subassembly of the gas-interrupter module, and enabling its ready application to a grounded metallic tank-type of circuit-interrupter, or, alternatively, to gas-insulated transmission-line equipment, as desired. Improved supporting features involve the utilization of a pair of upstanding side-insulating supporting shields, which substantially solely support the upper relatively-stationary contact and shielding assembly, apart from any support needed by the upper terminal-bushing, when used. Additionally, the invention comprises improved rod guiding features for the movable operating cylinder, improved shielding structure on both the stationary and movable contact structures and improved capacitor-tube mounting-assembly arrangements, an improved lower metallic base-support, having a shielding portion, which shields the relatively-sharp-cornered hardware features, such as the movable-contact guiding stem, reducing the electrical gradient, employing tubular shielding structures adjacent the central heavy supporting plate for relieving the electrostatic field, and employing, additionally, an improved upper electrostatic shielding arrangement, easily attached and disassembled by a simplified spring-clip assembly. An additional feature of the invention is the use of a spherical bearing located at the upper end of the insulating pull-rod assembly, or operating-rod assembly to compensate for inaccuracies in manufacture, and improving the general assembly features adapting the modules for bench-assembly inspection.

International Classification:

H01H 3388

US Classification:

200148A

Abstract:

A gas-insulated circuit interrupter includes stationary and movable contact assemblies which are cooperable with each other to transmit or interrupt electrical current. Means are provided for moving the movable contact assembly, and for establishing a flow in the circuit interrupter during an opening interruption to estinguish the arc which is drawn between the stationary and movable arcing contacts. A hollow insulating nozzle is utilized for directing gas flow. The interior surface of the nozzle is shaped so as to direct a flow of insulating gas to blast into the arc, and the exterior surface of the nozzle is contoured such as to deflect the flow of insulating gas away from the movable main contacts.

Appl. No.:

6/373751

Inventors:

Robert L. Hess - North Versailles PA
Zeno Neri - Wilkins Township, Allegheny County PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01B 1726

US Classification:

174 31R

Abstract:

A gas-insulated bushing includes an elongated hollow insulating shell with an elongated inner conductor disposed therein spaced apart from the insulating shell, with an insulating gas electrically insulating the conductor from the insulating shell. A terminal is sealingly secured to the insulating shell and prevents the escape from the interior of the shell of the insulating gas disposed therein. The terminal includes an electrical connector which is external to the shell and which includes a portion extending inwardly into the shell. This electrical connector is aligned with, but spaced apart from, the electrical conductor to provide room for thermal expansion of the electrical conductor. Provisions are included for electrically connecting the central electric conductor with the electrical connector, which includes a conductor adapter secured to the electric conductor and extending outwardly therefrom to adjacent the electrical connector in an overlapping relationship, with the adapter having a recess therein in which is disposed a contact finger which extends outwardly from the adapter to slidingly contact the electrical connector.
