  • N2/SF6 gas Mixtures — Large Scale Application in Gas

    Abstract The application of N 2 /SF 6 gas mixtures with SF 6 -contents between 10 % and 20 % reduces the costs for the insulating gas remarkably. This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance applications of this technique is improved on the user side.

  • Problems of the application of N2/SF6 mixtures to gas

    Sep 21, 2001 · Abstract. In designing a gas‐insulated bus (GIB) using N 2 /SF 6 mixtures, there are many application problems, such as the mixture pressure needed in order to maintain the required dielectric and heat transfer performance. Problems of recycling SF 6 are also essential in applying N 2 /SF 6 mixtures. This paper presents the minimum breakdown field strength at lightning impulse and the temperature rise of the conductor and enclosure as measured for N 2 /SF 6 mixtures.

    The results showed that thermal properties of 20% SF6/N2 (volume fraction of SF6 is 20%) mixture has faster degradation than 40% SF6/N2 mixture. As ratio of SF6 content decreases, thermal stability of the system decreases, and the decomposition process of SF6 is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in SF6/N2 mixture.
