  • COLD-WEATHER APPLICATION OF GAS MIXTURE (SF6/N2, SF6/CF4

    Manitoba Hydro presently owns and utilizes three gas handling carts. These carts are manufactured by DILO Company, Inc., and are capable of handling SF 6, CF 4 and N 2 in either the gaseous or liquid form. A diaphragm compressor allows a storage vessel or gas containment compartment to be evacuated to an absolute pressure of 50 mbar.

  • Mixutures of SF6 with nitrogen or tetrafluoromethane as

    SF6 Mixtures In addition to the use of sulphur hexafluoride (SF 6 ) as a single gas, mixtures of SF 6 with nitrogen (N 2 ) or tetrafluoromethane (CF 4 ) are also used as insulating or test gas. The IEC recommends a purity of SF 6 of at least 99.7 vol.-% for the use in mixtures.

  • SF6 gas Mixtures Service supply - karina.net.pl

    N2 / SF6 gas mixtures (5 - 10 % by volume of SF6) are employed to refine pure Aluminum or its alloys at melt temperatures in the range 650 - 750 C. SF6 is a source of fluorine atoms reacting in the melt and removing inclusions of H2, oxides, particles and other casting impurity.

  • 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.

  • Static Field Breakdown of SF6-N2 Mixtures in Rod-Plane Gaps

    Mixtures containing 0 to 100% SF6 are studied over a pressure range of 100 to 500 kPa. The results show that for such gaps, the dielectric behavior of SF6-N2 mixtures is very similar to that of pure SF6. A discontinuity is reported in the breakdown voltagepressure characteristics of SF6 and SF6-N2 mixtureswhen the rod electrode is positive.

  • IMPULSE BREAKDOWN IN SF6, SF6/N2 AND SF6/N2/PERFLUOROCARBON

    Jan 01, 2013 · ABSTRACT. The impulse breakdown strengths of binary mixtures of SF 6 /N 2, SF 6 /PFC (perfluorocarbon), PFC/N 2, and ternary mixtures of SF 6 /PFC/N 2 have been measured for nonuniform field point-plane geometry. Both standard lightning (1.2 μs rise/50 μs decay) and switching (200 μs rise/2000 μs decay) waveforms of positive and negative polarity were employed.

  • Separation of SF6 from SF6/N2 mixture using metal–organic

    Feb 15, 2015 · 1. Introduction. Sulfur hexafluoride (SF 6) has been widely used as an insulating and etching gas in the electric industry due to its chemical stability, non-toxicity, non-combustibility, and good insulating characteristics , ; however, SF 6 is a very potent greenhouse gas since its global warming potential (GWP) is 23,900 times higher than CO 2, and its lifetime is estimated to be 3200 years

    Jan 01, 1987 · This paper describes the results of diffusion experiments performed in a cylindrical vessel (2 m long) simulating the geometry of GIS compartments. The horizontal and vertical mixing rates of a wide variety of gases (air, N 2, CO 2, CH 4, CHF 3, CF 4, C 2 F 6, C 3 F 8, cyclo-C 4 F 8) with SF 6 were measured at a pressure slightly above atmospheric. The diffusion behavior of polar molecules methanol and water vapors was also studied.
