Multi-Phase Compressed-Gas Circuit-Breaker Construction
US Patent:
4013853, Mar 22, 1977
Filed:
Nov 27, 1974
Appl. No.:
5/527930
Inventors:
Thomas E. Alverson - Brookfield OH
Otto H. Soles - North Huntingdon PA
Melvyn D. Hopkins - Pittsburgh PA
Charles E. LeRow - Jeannette PA

Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
H01H 3354
US Classification:
200148B
Abstract:
An improved multi-phase compressed-gas circuit-breaker installation is provided having the three or more circuit-breaker assemblies mounted upon a horizontally-extending rigid frame structure, with the high-pressure and low-pressure gas-reservoir tanks disposed close to the ground, and having the circuit-breaker assemblies extending upwardly in spaced lateral horizontal relationship. Pressurized pipes, or conduits connect to the circuit-breaker assemblies, the pressurized pipes containing, of course, the internal high-voltage power-conductors at the centers of the pressurized pipes, as well known by those skilled in the high-voltage power-transmission art of the pressurized gas-insulated type.
Longitudinally-extending contact-operating linkage is provided lengthwise along the supporting frame structure, in an easily accessible location, and the control compartments and gas-compressor units are disposed in an advantageous relationship and location with regard to the gas-storage tanks, which leads to easy servicing and maintenance.
Operating Mechanism And Position Indicator For A Circuit Interrupter
US Patent:
4016384, Apr 5, 1977
Filed:
Nov 19, 1974
Appl. No.:
5/525124
Inventors:
Charles E. LeRow - Jeannette PA
Ronald W. Crookston - Trafford PA
Ronald W. Crookston - Trafford PA
Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
H01H 3300, H01H 900
US Classification:
200148R
Abstract:
An improved circuit-breaker position-indicator is provided for a gas-type circuit-interrupter in which the circuit-breaker structure is enclosed within an outer pressurized casing at a different pressure than the gas pressure interiorly of the circuit-breaker itself. Improved means are provided for effecting manual movement of the circuit-breaker contacts by a hand-jack assembly, when desired. Visible safe indication of the correct circuit-breaker open and closed-circuit positions is obtained at all times for safe and dependable operation of the circuit-breaker.
