<P>PROBLEM TO BE SOLVED: To provide a gas insulated electric device that surely traps a metal foreign matter showing various behavior, reduces manufacturing costs, and improves insulation reliability. <P>SOLUTION: A conductor 1 is installed in a grounded tank 2 filled with insulating gas via an insulating spacer 3. A metal plate 16 is provided with holes 13 for trapping the metal foreign matter that rotationally moves, and holes 14 for trapping the metal foreign matter that vertically moves in an erected state. A sidewall 15 is provided in a direction from the holes 13, 14 toward the grounded tank 2. Further, the metal plate 16 is electrically connected in parallel with the grounded tank 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
