摘要： A photoionization detector includes a housing, electrical contacts within the housing and an easily removable and replaceable photoionization chamber within the housing. The photoionization chamber includes a cathodic electrode and an anodic electrode which may be coated with a thin layer of material. The photoionization chamber and the associated cathodic electrode and anodic electrode are removable from within the housing as a unit. The photoionization chamber makes electrical connection with the contacts when seated within the housing regardless of the orientation of the photoionization chamber about an axis.

摘要： A moving contact assembly for a high-current interruption electric power switching apparatus has an inner carrier for the contact fingers that is rigidly held in a withstand position in an outer carrier by a spring biased cam follower pin engaging a cam profile on the inner carrier and configured to positively seat an inner carrier stop against an outer carrier stop on the outer carrier and to rapidly drive the inner carrier to a blow open position in response to a fault. The cam profile has an extended width divided between spaced apart cam profile sections to absorb the high closing and withstand forces. An abutment on the outer carrier resists bowing of the cam follower pin between the cam profile sections. Complementary convex and concave partial cylindrical surfaces on the inner carrier and a gas shield on the moving assembly carrier body maintain an arc gas seal during blow open.

摘要： A multiple electrode structure for a vacuum interrupter that encourages formation of a diffuse arc includes a pair of disk-shaped, confronting electrical contacts that are relatively movable between a closed circuit position and an open circuit position and that are enclosed by a vacuum envelope. Each contact has generally spiral-shaped arms defining slots therebetween. The slots gradually widen towards the periphery of the contacts. In addition, the contacts are rotated relative to each other such that the tip of each spiral arm of one contact faces a generally radially extending portion of a spiral arm of the other contact. A generally tubular metal vapor shield surrounds the contacts within the envelope and is electrically isolated from at least one of the contacts in the open circuit position. The design and orientation of the contacts increases the radial component of the self-induced magnetic fields generated by the current in the interrupter. The Lorentz force on a high-current columnar arc between the contacts motivates the arc to attach to the vapor shield and become diffuse.

摘要： A current limiting power switch has a monolithic stationary conductor with a conductor section that mounts fixed contacts that engage moving contacts on moving contact fingers to form a reverse current loop with the contacts closed. A terminal section projects transversely from one end of the conductor section and an arc runner section extends from the other end. The tapered arc runner has a generally laterally centered tapered area that gathers the arcs and urges them along a raised rib on the arc runner to an arc chute. A reinforcing rib running from the back of the conductor and arc runner sections to the terminal section resists distortion of the monolithic stationary conductor by the high temperatures and closing and electromagnetic forces during interruption.

摘要： An axial magnetic field vacuum interrupter includes electrode stems each having a member made of a highly conductive material, such as high conductivity copper. The conducting member has a plurality of angularly spaced, longitudinally extending slots that can be left open or filled with a material of lower conductivity. The member can by surrounded by an annulus of a lower conductivity material for added structural support. An axial core fabricated of a lower conductivity material can also be used. The slots and the lower conductivity materials reduce the production of eddy currents in the stems by the axial magnetic field, and thereby serve to reduce the phase delay between the field and the current and improve the quality of the field in the intercontact region.
