Abstract: A power switching apparatus comprising a vacuum interrupter assembly and a switching assembly connected in parallel between a pair of terminals, each of the terminals being connectable in use to an electrical circuit. The vacuum interrupter assembly includes at least one vacuum interrupter having a pair of electrically conductive rods connected at a first end to a respective one of the terminals and extending at a second end into a vacuum tight enclosure. A first electrode is mounted at or near the second end of a first of the electrically conductive rods and a slotted coil including a support base mounted at or near the second end of a second of the electrically conductive rods. A second electrode is mounted on an inner surface of the slotted coil and a third electrode is mounted on the support base. The second ends of the electrically conductive rods extend into the vacuum tight enclosure such that the first and third electrodes define opposed contact surfaces and at least one of the electrically conductive rods is movable relative to the other to open or close a gap between the opposed contact surfaces. The switching assembly includes at least one crossed-field plasma discharge switch that does not carry any current in its open state and conducts and carries current in its closed state. The switching assembly is controllable to switch between open and closed states to modify, in use of the power switching apparatus, a current flowing through the vacuum interrupter assembly.

Abstract: An axial magnetic field high voltage vacuum interrupter for interrupting the flow of electrical current in high voltage electrical circuits has a housing with a vacuum therein and two switch contacts disposed within the housing. The switch contacts are movable with respect to each other between a first position in which they are in contact with each other and a second position in which they are separated from each other by a space sufficient to interrupt the current flow through them. One or both of the switch contacts comprise a plurality of helically coiled current-carrying bars, an electrically conductive stem portion conductively coupled to the helically coiled bars at one end, and an electrically conductive contact member conductively coupled to the helically coiled bars at another end. Each of the helically coiled bars has a first portion which extends radially outward from the stem portion and a second portion which is helically coiled about an axis substantially parallel with the stem portion.

Abstract: An improved vacuum switch has slotted, flexible, discus-shaped contact discs attached to the current carrying contact bolts. In the open circuit case, a gap exists between each contact bolt and its corresponding contact disc and between the two discs. In the closed circuit case, the contact bolts drive the contact discs against one another, slightly deforming the contact discs, resulting in a low resistance current path. As the switch starts to open, the contact bolts first separate from the adjacent disc surfaces. As the switch opens further, any arc that ignites exists only between the contact discs. Tangential slots in the contact discs guide the arc toward the center of the contact discs. The flexible discs assume their previous undistorted shape when the switch has opened.

Abstract: In high-current vacuum switch devices wherein the arc must transfer from the contacts to auxiliary electrodes, excessive contact erosion can be avoided by making this transfer occur as quickly as possible. Rapid transfer is facilitated by fabricating the contacts of refractory metal and the auxiliary electrodes of a material that is easily vaporized, consistent with chopping and recovery requirements, such as copper or iron.

Abstract: A vacuum type circuit interrupter is provided having separable mating contacts. Multiple arc energy dissipating surfaces are attached to each contact. The arc energy dissipation surfaces are spaced from the contact to which they are attached, and at least a portion of the surfaces extend longitudinal of the vacuum interrupter. The arc is initiated at the primary contact surfaces, adjacent the central point of separable contact structure, and is moved to the arc dissipation surfaces which extend radially and/or axially from the contacts. The arc is rapidly moved to the energy dissipation surfaces and the primary contact surfaces are prevented from becoming eroded.

Abstract: A vacuum type circuit interrupter is provided having separable contacts. Each separable contact comprises multiple contact surfaces which are resiliently attached to the main body of the contact by contact surface supporting means. The contact surface supporting means are constructed so that if contact surfaces are welded and if force is applied to separate the contacts, a nonuniform stress distribution is set up in any weld at the contact surfaces. This stress concentration, due to the elastic bending of the contact surface supporting means, aids in breaking the weld and allowing the contacts to separate.
