Abstract
This high voltage circuit breaker comprises a vacuum type interrupter and a fluid-blast type interrupter electrically connected in series and arranged to be opened substantially simultaneously so that concurrent arcing occurs in the two interrupters until about the time a natural current zero is reached. The vacuum interrupter is relied upon to withstand the usual recovery voltage during the initial period after arcing and the fluid-blast interrupter to withstand the recovery voltage after this initial period. Immediately after the circuit has been interrupted by this coaction of the two interrupters, the vacuum interrupter is closed while the fluid blast interrupter remains open, thus relieving the vacuum interrupter of continuing voltage appearing across the circuit breaker.
