    In the case of SF 6 /N 2 mixtures, good agreement is found for the effective ionization coefficients. The attachment coefficients do not saturate but rather increase with the SF 6 partial density. In SF 6 /CCl 2 F 2 mixtures, the variation of ᾱ is found to be nonlinear with the percentage mixture ratio.

  • 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.

    Feb 15, 2015 · The adsorption capacity of SF 6 on the MIL-100 (Fe) granule was 1.658 mmol/g, and the selectivity of SF 6 over N 2 was 24.4 at 1 bar and 298 K. Compared to Zeolite 13X, the breakthrough time of the MIL-100 (Fe) granule was much shorter than Zeolite 13X at 1 bar, but the breakthrough time became similar with Zeolite 13X at 9 bar.

    There are two kinds of mixtures: heterogeneous and homogeneous. In heterogeneous mixtures, two or more phases intermingle, but remain physically separate. Heterogeneous mixtures can include mixtures consisting of (i) two liquids, (ii) a solid and a liquid, (iii) a liquid and a gas, or even (iv) a gas and a solid.

    Abstract: A method to calculate the uniform field breakdown gradients for SF6-N2, SF6-air and SF6-CO2 mixtures is discussed. Calculated values of the breakdown gradients in these mixtures are compared with experimentally measured values using plane-plane electrode configuration and direct applied voltages. The results show a reasonably good degree of agreement between the calculated and the measured values.
