Abstract
Official abstract text for this publication.
An alternating current vacuum switching device for switching an electrical circuit under load and no load conditions, and optionally short-circuit conditions is disclosed. The switching device comprises: a vacuum evacuated housing; first and second electrodes within the housing; and an actuator for moving the first electrode relative to the second electrode to mechanically engage and disengage the electrodes to perform a switching function, wherein the first electrode is wholly located within the vacuum evacuated housing such that movement of the switching function occurs solely within the housing. By having movement of the switching function solely within the housing, the reliability of the vacuum switching device is improved.
First claim
Opening claim text (preview).
1 . An alternating current vacuum switching device for switching an electrical circuit under load and no load conditions, and optionally short-circuit conditions, the switching device comprising: a vacuum evacuated housing; first and second electrodes within the vacuum evacuated housing, wherein the first electrode is wholly located within the vacuum evacuated housing; means for moving the first contact relative to the second electrode to consummate a switching function solely within the vacuum evacuated housing and without a bellows. 2 . The switching device of claim 1 , wherein the means for moving the first contact is disposed external of the vacuum evacuated housing. 3 . The switching device of claim 1 , wherein the means for moving the first contact comprises a permanent magnet actuator. 4 . A method of switching a vacuum switching device comprising: providing a vacuum evacuated housing; disposing first and second electrodes within the vacuum evacuated housing, wherein the first electrode is wholly located within the vacuum evacuated housing; and applying a magnetic field to the first electrode to cause it to move from open to closed, or closed to open, relative to the second electrode without moving a mechanical component that passes through a wall of the vacuum evacuated housing. 5 . The method of claim 4 , wherein applying a magnetic field comprises providing a permanent magnet actuator magnetically operably associated with the first electrode. 6 . The method of claim 4 , wherein the permanent magnet actuator is provided external of the vacuum evacuated housing.
