Abstract
354,873. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 22, 1930, No. 15828. Convention date, Aug. 20, 1929. [Class 38 (v).] In an "expansion" switch, as described in Specification 16360/30, the vapour from the expansion chamber is vented to atmosphere or to an adjoining room by means of a metal pipe which is insulated from earth. As shown in the Figure, the exhaust pipe 17 from the upper division 12 of the expansion chamber is supported by wall insulators 18 and passes to the outside through a roof insulator 19. In modifications the exhaust pipe passes horizontally through a wall insulator to the outside or vertically through the floor.
