ABSTRACT:
An interrupter (10) having an outer housing (62) adapted to contain an arc-extinguishing fluid, a fixed tubular electrical current carrying member (40) disposed at one end; a movable tubular current carrying member (30) disposed in an end-to-end relationship with the fixed electrical current member (40); a prime mover for stroking the movable current carrying member (30) between an open position and a closed position; a piston means (16), carried by the movable electrical current carrying member, for supplying pressurized fluid between two current carrying members when the interrupter is opened; an insulated plenum means (22), carried by the piston means (16) and disposed around the contacting ends of the two current carrying members, for confining the flow of pressurized arc-extinguishing fluid into the gap formed between the two current carrying members when the interrupter is opened so as to direct ionized fluid and arc by-products away from the interior surfaces of the outer enclosure and to shield the operating components within the interrupter from direct blast of arc by-products released by the arc; arcing tips (32) and (42 ) carried on movable tubular current-carrying member (30) and fixed tubular electrical current-carrying member (40) respectfully; and, gas shield seal (36) comprised of C-Ring (37) and teflon sleeve (38).
