Appliion and Recycling of SF6 gas Mixtures in Gas

Unlike pure SF 6 gas, handling and recycling SF 6 gas mixtures is a complex job, and it is in urgent need of an outline of handling and recycling SF 6 gas mixtures since more and more SF 6 gas mixtures insulated equipment are in service. In this paper, we introduce the situation of mixed-gas circuit breakers at different system voltage, and

VALIDATION METHODS OF SF6 ALTERNATIVE GAS

gases for gas proportion corresponding to -15°C conditions. That means the gas mixture has no liquefaction from high temperature down to -15°C. For lower temperatures part of the gas is liquefied, and as a consequence dielectric performances are reduced. Alternative gas …

Pure SF6 and SF6-N2 mixture gas hydrates equilibrium 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.

Breakdown Strength of N2-SF6 Gas Mixtures Containing 10%

Abstract. SF 6 as insulating gas has a very good dielectric strength. Therefore, SF 6 is used in many appliions. Nowadays, it is investigated again whether SF 6-N 2 mixtures can replace pure SF 6 in for example gas-insulated substations and lines. For pure SF 6 the optimal gas pressure varies between 4 and 6 bar. In order to find a suitable SF 6-N 2 gas mixture to substitute SF 6, the gas
