Abstract
An interrupter is provided having: an outer enclosure or tank adapted to contain an arc-extinguishing fluid; a fixed tubular electrical current carrying member disposed at one end of the tank; a movable tubular current carrying member disposed in the tank in an end-to-end relationship with the fixed electrical current member; a prime mover for stroking the movable current carrying member between an open position and a closed position; an electrically conductive piston means, carried by the movable electrical current carrying member, for supplying pressurized fluid into the gap formed between two current carrying members when the interrupter is opened and for purging the vicinity of the gap when the interrupter is closed; a non-electrically conductive base means, carried by the outer enclosure, for housing the piston means and for guiding the movement or the stroking of the movable current carrying member; and an insulated plenum means, carried by the piston means 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.
