Abstract

810,406. Liquid-blast switches. PRINCE, D. C. March 19, 1957 [Nov. 20, 1956], No. 8938/57. Class 38 (5). A liquid-blast switch comprises a horizontal insulating housing 11 with a vent 12 opening upwardly from the liquid in the housing, a hollow insulating cylinder 13 within the housing and having an opening in alignment with the vent, a piston 15 slidable in the cylinder, a bulkhead 16 supporting a fixed contact 18, a movable contact 20, a piston rod 17 operable to move the piston towards the bulkhead while disengaging the movable contact from the fixed contact to establish an arc gap, a nozzle 22 leading to the gap from the space between the piston and the bulkhead, and an arc-splitting baffle 23 disposed on the opposite side of the gap from the nozzle, whereby movement of the rod 17 to establish the gap causes the piston 15 to displace liquid through the nozzle to force the arc against the baffle. The Figure shows a portion of a multi-break arrangement in which the piston associated with one " break " carries the moving contact of the adjacent " break." Interconnection between the " breaks is provided by rods 19 which extend. from the fixed contacts 18, the moving contacts 20 being slidable on the rods 19. Specification 743,939 is referred to.
