Abstract
703,101. Air-blast circuit-breakers. CESKOSLOVENSKE ZAVODY TEZKEHO STROJIRENSTVI NARODNI PODNIK, and HOUST, F. June 19, 1951 [June 20, 1951], No. 14539/51. Class 38(5) In a circuit - breaker having nozzle contacts 1, 2, one or both of which may be movable and through which the gas blast is supplied, the contacts are surrounded by coils 3 electrically connected to the contacts at 4 and insulated therefrom at 5. The arrangement is such that the roots of the arc 11 formed on contact separation are blown by the gas on to the end turns of the coils (as shown), thereby connecting the coils in series to set up a magnetic field which rotates the roots around said turns, the arc being blown against radial cooling ribs 7 in a chamber 6, where it is extinguished.
