Phase Segregated Type 6 Gas Insulated - Fuji Electric

sf6 gas gas flows during arc quenching. Open position When trip commences, the puffer cylinder is driven towards the moving contact support. The Sulfr hexafluoride gas trapped in the enclosed space is thereby compressed. As soon as the arcing contacts separate, the compressed Sulfr hexafluoride gas flows through the arc quenching nozzle and extinguishes the arc.
