<p><P>PROBLEM TO BE SOLVED: To provide a gas simple recovery method for gas insulating device that recovers gas in a short time, without having to put time and effort for transportation of the gas insulating device. <P>SOLUTION: The gas simple recovery method includes a first step for recovering one part of SF6 gas 20 to a gas collection bag 10, by opening a valve of a replenishing opening 3 so that pressure inside the gas insulating device 1 is made the same pressure as the atmosphere after connecting one end of a hose for gas 12 to the replenishing opening 3 of the gas insulating device 1 and connecting the other end to the gas collection bag 10 for recovering the SF6 gas 20; and a second step for recovering the remaining SF6 gas 20 to the gas collection bag 10 via the hose for gas 12, by removing the hose from a gas 12 that is connected to the gas collection bag 10 from the replenishing opening 3 and connecting to a connecting opening for a pressure gauge 4, after removing the pressure gauge 4 from the gas insulating device 1 on the one hand and injecting water from the replenishing opening 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
