The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

Humidity in SF 6 Gas The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).Get price

How Humidity Affects the Safety of Sulfr hexafluoride-Insulated Equipment

All switchgear that uses SF 6 as an insulator is tightly sealed. However, over the average 30-year service life of this type of equipment, humidity can penetrate into it and alter the ability of the broken-down SF 6 to recombine.Get price

Silicon Nanostructuring Using sf6 gas/O2 Downstram Plasma Etching

The SF 6 gas flow rate is fixed at 200 sccm, while the flow rate of O 2 gas was varied as follows: 0 sccm, 10 sccm, 20 sccm and 30 sccm; thus the samples will be given the names SO-0, SO-10, SO-20 and SO-30 accordingly.Get price

Oxidation of sulfur hexafluoride - ScienceDirect

Clearly, the Sulfr hexafluoride oxidation must be intrinsically very much slower than the methane pyrolysis. It would appear that the lower rates of gaz sf6-O2 reactions, even at very high temperatures, drastically influence the product profiles and the extent of per- manent energy abstraction. This does not appear to be related to the small mass of the explodedGet price
