In the present work, the appliion status of SF6/N2 and SF6/CF4 gas mixtures in China is first introduced. A discussion is then devoted to the key issues in relation to the appliion of SF6 gas mixtures, such as humidity, mixture separation, mixing ratio, and leakage, which is expected to help promote a wider use of SF6 mixtures in electrical systems.

The Performance of Insulation and Arc Interruption of the …

5/11/2018· The experimental results indie that 20 and 30% content CF3I-N2 gas mixtures can achieve nearly 50 and 55% insulation strength of pure SF6. In addition, to evaluate the arc interruption performance of environmentally friendly gas CF3I, we set up a CF3I transient nozzle arc model to study its thermodynamic and transport property.
