ABSTRACT:
An electric circuit-breaker in which the arc extinction chamber is filled with liquefield SF6 under pressure.
The moving contact of the circuit-breaker cooperates with a blast-piston which, during opening of the breaker and after the moving contact has reached its ultimate open position, continues its travel in order to produce an intensive and protracted circulation of liquid dielectric from the arc extinction chamber in the region where the arc strikes across the contacts.
Applications to ultra-high-speed breaking of high-tension, high-intensity alternating currents.
