Title: SF6 Magnetic-Puffer Circuit Breaker for 34.5 kV, 1500 MVA
Abstract: A circuit breaker of a new type has been developed as the removable breaker element for metal-clad switchgear for 23/34.5 kV service. It is a single pressure, dead-tank SF6 circuit breaker which employs magnetic driving action produced by the fault current to drive the gas through the arc to interrupt it. Complete development tests have been performed, as required by applicable standards, as well as additional tests, considered justified, to prove reliability. The resulting breaker is small in size, quiet in operation, and provides features heretofore unavailable in circuit interrupters.
