摘要： The invention provides a vacuum interrupter with improved separation of functional elements. The interrupter includes separable contacts for carrying continuous current and rod electrode arrays for carrying fault currents. The housing for the interrupter is evacuated, and has a plurality of interior chambers. The rod electrodes are in one chamber and the separable contacts are in an adjacent chamber. A communicating opening is provided between the chambers. The rod electrodes and separable contacts are connected in parallel in a common circuit. When the contacts are separated, arcing products are conveyed to the adjacent chamber through the communicating opening to initiate arcing between the rod electrodes.

摘要： 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.

摘要： 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. A plasma trigger is mounted in the tip of one of the centrally disposed electrodes. When a high voltage is connected across the high voltage terminals and a trigger signal is applied to the plasma trigger, a high arc current transits the electrodes and the evacuated spaces therebetween in both the first and second chambers. The arc current occurs substantially simultaneously and has the same magnitude in both chambers.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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. A second generally stationary contact is supported on said second support structure in a position intermediate the locations at which the second support structure is attached to said predetermined rod electrodes of said second plurality. First and second movable contacts are provided for respectively engaging the first and second generally stationary contacts. A first movable contact rod on which the first contact is mounted extends in sealed relationship through said first metal end cap. A second movable contact rod on which said second contact is mounted extends in sealed relationship through said second metal end cap. The two pairs of engageable contacts are electrically connected in parallel with each other while the interrupter is closed.
