Appl. No.:

5/776641

Inventors:

Joseph A. Rich - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01H 3366

US Classification:

200144B

Abstract:

A vacuum switch for high voltage operation includes a fixed gap structure comprised of two rod array assemblies in series cascade within the same vacuum envelope, along with a single break butt contact electrode assembly, wherein the movable contact, upon opening, passes entirely through the conducting midplane and takes up a position of symmetry with respect to the fixed contact and the midplane.

Appl. No.:

5/678294

Inventors:

Joseph A. Rich - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01H 3366

US Classification:

200144B

Abstract:

High interruption voltage capability within a vacuum switch of limited physical size is achieved by combining a diffuse arc electrode structure with provision for retracting one or both of a pair of movable butt contacts into an approximately field-free region. On separation of the contacts, an arc is initiated on the contacts and then transferred to a fixed gap electrode structure comprising a coaxial cylindrical electrode assembly in which the current path is folded back on itself to reduce the azimuthal magnetic field external to the outer cylindrical surface, causing the arc to burn in a diffuse mode over a greatly enlarged electrode surface area.

Appl. No.:

6/014352

Inventors:

Joseph A. Rich - Schenectady NY

Assignee:

Electric Power Research Institute, Inc. - Palo Alto CA

International Classification:

H01H 3366
H01J 2122

US Classification:

313146

Abstract:

In a rod array vacuum arc device, conductive protuberances are positioned on the conductive rod support plates. The protuberances positioned on each plate are aligned axially with the opposed rod electrodes. The protuberances increase the dielectric strength of the gap between each plate and the opposed electrode.

Appl. No.:

5/830211

Inventors:

Joseph A. Rich - Schenectady NY

Assignee:

Electric Power Research Institute, Inc. - Palo Alto CA

International Classification:

H01J 2120

US Classification:

313198

Abstract:

A triggered vacuum gap tube includes an evacuated envelope with high voltage terminals at opposite ends of the envelope. The envelope is divided into two chambers by a mid-plate therein having a centrally located aperture therethrough. The first of the two chambers has an end plate mounting one of the high voltage terminals and also mounting an array of rods or electrodes which extend inwardly toward the mid-plate. The second of the two chambers also has an end plate mounting the other high voltage terminal and also having an array of rods or electrodes extending therefrom toward the mid-plate. The mid-plate has mounted therein an array of through rods or electrodes which extend in one direction into the first chamber and in the opposite direction into the second chamber. The through mid-plate mounted electrodes lie in side-by-side spaced relation with the end plate mounted electrodes in both the first and second chambers. The end plate mounted arrays of electrodes have a centrally disposed electrode with a tip which is proximate to the centrally located aperture in the mid-plate.

Appl. No.:

5/589892

Inventors:

Joseph A. Rich - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01H 3366

US Classification:

200144B

Abstract:

A vacuum arc discharge device comprises a rod array structure of interdigitated, continuous current-carrying electrodes and arc electrodes, with an assembly of movable contacts near one end of the device respectively coupled to the continuous current-carrying electrodes. Continuous and fault currents are thus divided among the contact assemblies, reducing total magnetic force tending to separate the contacts and increasing current capacity of the device.

Appl. No.:

5/769275

Inventors:

Joseph A. Rich - Schenectady NY
Willem F. Westendorp - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

H01J 1726

US Classification:

313146

Abstract:

In a vacuum arc discharge device of the rod array type, improved arc diffuseness and enhanced ability to hold off voltage during the recovery period are obtained by tapering the rods, with the maximum diameter occurring near the free ends. A higher threshold current for rod anode spot formation and melting also results.

Assignee:

General Electric Company - Philadelphia PA

International Classification:

H01G 3366

US Classification:

200144B

Abstract:

A vacuum-type circuit interrupter comprises two pluralities of rod electrodes positioned to form a ring of electrodes in which the electrodes of the first plurality interleave with those of the second plurality and are spaced circumferentially of the ring from the immediately adjacent electrodes of the second plurality. The rod electrodes of said first plurality are mounted on and electrically connected to a first conductive end cap of the interrupter. The rod electrodes of the second plurality are mounted on and electrically connected to a second conductive end cap of the interrupter. First conductive support structure extends transversely of the rod electrodes and is attached to the distal ends of predetermined rod electrodes of said second plurality. A first generally stationary contact is supported on said first support structure in a position intermediate the locations at which the first support structure is attached to said predetermined rod electrodes of said second plurality. Second conductive support structure extends transversely of the rod electrodes and is attached to the distal ends of predetermined rod electrodes of said first plurality.
