<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated power apparatus and its abnormality detecting method capable of detecting an inside abnormality with high sensitivity, and capable of taking out an absorbent while continuing its operation. <P>SOLUTION: This gas-insulated power apparatus accommodates a conductor 3 in an electrically insulated state inside a grounding tank 2 sealed with an insulating gas 1, and removes by absorbing a decomposed gas generated from the insulated gas 1 inside the grounding tank 2 with the absorbent 4. This absorbent 4 is accommodated in an sealed container 5 separated from the grounding tank 2, the inside of the sealed container 5 is communicated with that of the grounding tank 2 by coupling the sealed container 5 to the grounding tank 2 so as to be separable from each other, and a first opening and closing valve 7 is provided that closes a communicated path 28 at the grounding tank side when the sealed container 5 is separated. By separating the sealed container 5 from the grounding tank 2 with the communicated path 28 at the grounding tank side closed, the absorbent 4 is analyzed to detect an occurrence of an abnormality inside the grounding tank 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
