Abstract

635,799. Gas-blast circuit-breakers. ETABLISSEMENTS MERLIN & GERIN. Dec. 29, 1947, No. 34356. Convention date, April 13, 1944. [Class 38 (v)] . A gas-blast circuit-breaker comprises fixed and movable hollow contacts 3 and 5, respectively, which co-operate in an arcing chamber 2 supported by a metallic collar 7 in an insulating tube 1. The contact 5 is separated from contact 3, against the action of springs 6, by a gas-blast through apertures 14, the resulting arc being extinguished by the gas which exhausts through the contacts. The contact 3 also serves as the fixed contact of a series disconnect switch having a movable contact tube 12, this switch preferably breaking the residual current through a resistance, connected across contacts 3, 5, after these contacts have opened.
