<p><P>PROBLEM TO BE SOLVED: To obtain the method of charging a gas-insulated switchgear with insulating gas which can shorten an insulating gas charging time. <P>SOLUTION: This is a method of charging the gas-insulated switchgear, which is equipped with a tank 2 using dry air as insulating gas, with insulating gas. A moisture adsorbent, which can absorb at least the quantity of moisture remaining in the tank and the quantity of moisture having infiltrated into the tank until the tank is opened next after its sealing or during the expected life of the product, is installed within the tank with air in, and dry air is added into the tank prior to sealing, without discharging the moisture and the air within the tank by vacuumization and gas replacement. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
