<p><P>PROBLEM TO BE SOLVED: To provide a gas-insulated transformer that contributes to improvement in reliability by preventing a local temperature rise of a tank by introducing a high temperature insulation gas uniformly into a gas flow passage inside the tank. <P>SOLUTION: A vertical partition board 11 is provided between the inner wall surface of the tank 1 and a side portion of a winding 3. The partition board 11 is provided so as to be landscape over the longitudinal direction of the tank 1 so as to face the entire winding 3 inside the tank 1. Between the upper edge of the partition board 11 and the inner wall surface of the tank 1, a gap 13 is formed to allow an insulation gas 6 to pass through. A space between the inner wall surface of the tank 1 and the partition board 11 forms a gas flow passage 15 which allows the insulation gas 6 to flow. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
