<p><P>PROBLEM TO BE SOLVED: To improve the regeneration process rate of sulfur hexafluoride gas. <P>SOLUTION: In the regenerating apparatus of sulfur hexafluoride gas, the objective gas for regeneration consisting of a mixture of sulfur hexafluoride gas as an insulating medium sealed in a casing 1 of an electric appliance, decomposed gas of the sulfur hexafluoride as an impurity, water, and non-condensing gas such as nitrogen and oxygen is recovered, from which the decomposed gas of sulfur hexafluoride and the water content are removed, and then the non-condensing gas is separated from the sulfur hexafluoride through a gas separation membrane of a separating means 11 for non-condensing gas. The apparatus is equipped with a compressing means 8 to compress the recovered objective gas for regeneration, and with a vacuum pump 14 to discharge the non-condensing gas separated by the removing means 11 for non-condensing gas. <P>COPYRIGHT: (C)2004,JPO</p> |
