Research of Discharge Characteristics of CO2 Gas in …

In order to find a new kind of insulates gas to substitute for SF6 gas, a discharge device has been development with shifter electrodes and adjusts distances automatic. Uniform electric field, non-uniform electric field had been achieved in this discharge device. The power-frequency voltage-withstand test of CO2 gas has been taken in these three kinds of electric field.

Wide Carbon Nanopores as Efficient Sites for the

SF 6 and SF 6-N 2 mixed gases are used widely as insulators, but such gases have high greenhouse gas potential. The separation of SF 6 from SF 6-N 2 mixed gases is an inevitable result of their use. Single-walled carbon nanohorns (CNHs) were used here for a fundamental study of the separation of SF 6 and N 2.The diameters of the interstitial and internal nanopores of the CNHs were 0.7 and 2.9

SF6/N2 Mixtures for GIS? • SF6 gas – specifically mentioned in Kyoto protocol. • Small quantities of SF6 in N2 can improve dielectric strength drastically. • All of the dielectric strength of SF6, nearly, can be achieved by adding less than 20% SF6 into N2. • SF6/N2 mixtures less susceptible to effects of field non uniformity than

IET Digital Library: AC creeping discharges …

This study is aimed at the characterisation of surface discharges propagating over different solid materials namely glass, bakelite and epoxy resin immersed in three gases and their mixtures (namely SF6, N2 and CO2, SF6/N2 and SF6/CO2) under AC voltage (50 Hz) in a point-plane electrode system. It is shown that the stopping length of discharges (Lf ) increases linearly with the applied voltage

Separation of SF6 from Binary Mixtures with N2 Using

2018-6-6 · The effective separation of SF6 from binary mixtures with N2 is critical for the proposed replacement of pure SF6, used as an insulating gas in high power industry, by the mixtures of these two gases. This replacement is driven by the fact that SF6 is the most potent greenhouse gas, with a global warming potential of 22,200 times that of CO2.

Separation of SF6 from SF6/N2 mixture using …

Despite the excellent properties of MIL-100(Fe), it has a disadvantage as an adsorbent for real field appliion due to its powder form after chemical synthesis. The powder type of MIL-100(Fe) is difficult to handle and causes large pressure drops as well as a problem with heat transfer in the adsorption system . For these reasons, the powder

2018-7-5 · A series of porous organic cages is examined for the selective adsorption of sulfur hexafluoride (SF6) over nitrogen. Despite lacking any metal sites, a porous cage, CC3, shows the highest SF6/N2 selectivity reported for any material at aient temperature and pressure, which translates to real separations in a gas breakthrough column. The SF6 uptake of these materials is considerably higher
