Abstract
900,254. Fluid-blast switches. NATIONAL INDUSTRI A.S., and LANGE, E. Aug. 19, 1960 [Sept. 25, 1959], No. 28762/60. Class 38 (5). A switch has a chamber 1 supporting fixed contacts 2, 3, 4, 5, 6, 7 and an axially-movable switch rod with conducting parts 16, 17, 18 and insulating parts 15, 19, 20, 21. When the switch is opened, Fig. 2, the insulating parts 19, 20, 21 of the switch rod in conjunction with fixed insulating members 28, 29, 30 form passages 8, 9, 10 in which the arcs drawn are extinguished by a flow of quenching medium produced by the pressure generated in the medium by the arcs. The fixed contacts and associated arcing terminals 32, 33, 34, 35, 36, 37 are carried by apertured connectors 25, 31 and tubular conductors 26, 27, and the conducting parts 16, 17, 18 of the switch rod carry arcdrawing terminals 38, 39, 40 and are tubular so that a channel extends through the switch for the flow of arc-extinguishing medium when the switch is open and to permit a cooling flow of medium when the switch is closed. The medium may be gas or liquid with or without powder and the powder and/or the insulating parts may be of gas-evolving material. Pressure-responsive outlet valves may be provided.
