Water hinders the recombination of sulfur and fluoride into sulfur hexafluoride.

This apparatus 30 contains an electrolytic cell 34 that generates fluorine gas and a cylinder 62 that holds a substitute gas selected from the group consisting of nitrogen fluoride, sulfur fluoride, and chlorine fluoride.

Advantages of six sulfur fluoride gas in electronic gases

The improvement involves addition of a nitrogen source to the feeding gas mixture comprising an oxygen source and sulfur fluoride.

Chemical properties of six sulfur fluoride gas in electronic gases

When there is a discharge in a gas insulation device filled with sulfur hexafluoride, hydrogen fluoride is generated, causing corrosion of fiberglass-reinforced plastic components inside the device.

The sulphur hexafluoride gas chamber is filled with sulphur hexafluoride gas.

Perfluorooctane sulfonate, its salts and perfluorooctane sulfonyl fluoride (contains the group C8F17SO2) are listed in Annex B of the Stockholm Convention.

The six sulfur fluoride gas has excellent insulation in the process of operation, and it has its unique thermal and electrical properties to a certain extent.

switchgear which contains sulphur hexafluoride or preparations containing sulphur hexafluoride; and

Because six sulfur fluoride gas has excellent chemical thermal stability, it will not be decomposed at 500 degree temperature if the purity is guaranteed.

A sulfur hexafluoride gas chamber (12) and a density relay (13) are provided in the equipment body, and the sulfur hexafluoride gas chamber is filled with a sulfur hexafluoride gas.

Also provided is a method for cleaning sulfur hexafluoride based on the apparatus for separating and cleaning sulfur hexafluoride gas.
