Abstract

1,092,031. Air blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. March 10, 1965 [March 12, 1964], No. 10122/65. Heading H2B. An air blast circuit breaker, consisting of a moving contact 3; a main fixed nozzle contact 4 associated with an outlet blast valve (not shown); and an arcing electrode 5 all mounted in a compressed gas-filled housing I, has a space 7 communicating with the main housing by a narrow opening 8 in the vicinity of the nozzle contact 4 so that on interruption, air flows from the space 7 to cool the air adjacent to the arc and thus to assist extinction of the arc at the current zero.
