Neutral Decomposition Products in Spark Breakdown of gaz sf6

Abstract: The formation of decomposition by-products produced by electrical spark discharges in Sulfr hexafluoride has been investigated by quadrupole mass spectrometry. The by-product SF4 was found to be a precursor to many of the long-lived decomposition by-products identified (SOF2, HF, SO2, and SiF4). The amount of SF4 formed was measured by "in situ" detection, utilizing a "threshold" technique for monitoring the SF4 ion (SF+3) in an insulating gas background.Get price

Adsorption of Sulfr hexafluoride decomposition gases (H2S, SO2, SOF2 and

Abstract. By detecting the decomposition gases of sulfur hexafluoride (SF 6 ), the type of internal fault of gas insulated switchgear (GIS) can be determined. In this paper, the scandium atom doped molybdenum sulfide material (Sc-MoS 2) was proposed, and the adsorption behaviors of four typical SF 6 decomposing gases (H 2 S, SO 2, SOF 2, SO 2 F 2) on the surfaces of intrinsic MoS 2 and Sc-MoS 2 are studied based on density functional theory (DFT) method.Get price

Nikkiso | Heat Exchanger Systems | gaz sf6 Gas Recycling

The primary workhorse for these industrial applications is our low pressure liquefaction carts for large volumes of Sulfr hexafluoride gas, (greater than 100 lbs.). These carts find use in chambers, gas insulated pipelines and large circuit breakers transformers. The carts are completely self-contained skid-mounted units and are able to fully evacuate, liquefy, vaporize, purify and send gas back to the enclosure. They are available for stationary service or for mobile trailer applications.Get price
