1 COLD-WEATHER APPLIION OF GAS MIXTURE (SF 6/N 2, SF 6/CF 4) CIRCUIT BREAKERS: A UTILITY USER’S PERSPECTIVE R. L. Middleton, P. Eng. Manitoba Hydro, Winnipeg, Canada SUMMARY Very low temperatures stress a circuit breaker in a complex manner.
breakdown voltage of SF6/CF4 mixtures as add CF4 gas to SF6 gas (0.1MPa). All SF6/CF4 mixtures which have SF6 gas of 0.01MPa satisfied the standard of 25.8kV GIS in power frequency withstand voltage test. Mixed gas of SF6 (0.01MPa) and CF4 (0.01~0.06MPa) show more good dielectric characteristics than pure CF4 gas (0.2MPa) in impulse and

Oct 15, 2009· In this study, we investigated the pure SF6 and SF6-N2 mixture gas hydrates formation equilibrium aswell asthe gas separation efficiency in the hydrate process. The equilibrium pressure of SF6-N2 mixture gas was higher than that of pure SF6 gas. Phase equilibrium data of SF6-N2 mixture gas was similar to SF6 rather than N2.
