Abstract

546,992. Gas-blast switches. AKT.-GES. BROWN, BOVERI, & CIE. Nov. 5, 1940, No. 16123. Convention date, July 26, 1939. [Class 38 (v)] In a gas-blast switch having a fixed nozzlecontact b and a protective resistance d which is switched-in by an axially-arranged auxiliary contact e swept-over by the arc, the auxiliary arc between b, e is extinguished by means of partitions g against which it is swept by the blast, the partitions being of metal, or of metal-tipped insulating material or wholly of insulating material which may evolve arcquenching gas. The blast at the exhaust end of the outlet passage may also be throttled by a cooler or silencer h. The resistance may be arranged on the outlet passage and wound in two layers which carry current in opposite directions. The Specification refers also to a hollow movable contact c and to both contacts being movable, and states that an isolating - switch may be arranged in series to interrupt the resistancecurrent.
