Abstract
This vacuum-type circuit interrupter comprises a plurality of pairs of separable contacts located within an evacuated envelope and electrically connected in parallel. The movable contact of each pair is mounted on a long, slender contact rod through which current is conducted to and from the associated contact pair. The contact rods, which are also electrically in parallel, are located in side-by-side physical relationship, and each is surrounded by a tube of highly conductive metal such as copper. The tubes are fixed to the interrupter envelope and are located in adjacent side-by-side relationship, thus defining flux-controlling shields around the contact rods in which eddy currents are induced to reduce the magnetic flux penetrating into the interior of each tube from any adjacent contact rod. Means is provided for producing substantially simultaneous contact-separating motion of the contact rods.
