    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 circuit interrupter arc chute includes first and second support portions, an exit portion supported by the support portions, and a plurality of arc plates supported by the support portions. The exit portion has one or more vent openings. The arc plates have a first edge offset from the exit portion and an opposite second edge distal from the exit portion. A plurality of insulating dividing members are disposed between the arc plates. The members have a first edge proximate the exit portion and an opposite second edge distal from the exit portion. The second edge of the members extends beyond the arc plate first edges and toward the arc plate second edges. The first edge of the dividing members extends beyond the arc plate first edge and away from the arc plate second edge.
