Abstract

The gas-blast type high voltage circuit breaker includes a first volume (27) in which gas pressure is increased due to heating by the breaking arc, the gas in this volume escaping to blow out the arc at current zero of the current being interrupted, and a second volume (37) in which the gas is compressed by a piston (39) at the beginning of the breaker opening phase, said gas being directed at the arc during the following phases. Circuit breaker further comprises main fixed contacts (21), fixed arcing contacts (24), main moving contacts and moving arcing contacts, the arc extending between the arcing contacts as the circuit breaker opens, said first volume (27) and second volume (37) being disposed to each side of the arcing region, being annular and ending in nozzles (26, 42) which direct separate jets of gas to the two respective roots of the arc.
