Abstract
PURPOSE: To provide a method of gas-insulated electric apparatus, comprising the steps of filling evaporable cleaning liquid into outer casing of an assembled gas- insulated electric apparatus, circulating the cleaning liquid in a predetermined manner and thereby cleaning the inside of the apparatus, and then supplying dry air into the apparatus to remove dust, moisture, etc. put into the apparatus at the time of assembling the same, with ease and completely.
CONSTITUTION: After opening connecting ports 20, 21 and pump valve 33a, evaporable cleaning liquid is drawn from tank 38 by means of pump 33 and filled into the space within outer casing 17. Then, the cleaning liquid is circulated from connecting port 19 via filter 34 to other connecting port 20 by means of pump 33, continuously for a proper time period. Subsequently, after closing pump valve 33a and opening valve 37a for introducing dry air, dry air is supplied into outer casing 17, thereby evaporating the cleaning liquid, and then it is discharged to the outside from connecting port 21. Finally, the space inside the outer casing 17 is evacuated and insulating gas is filled therein.
