<p>PROBLEM TO BE SOLVED: To eliminate need for removing insulation gas from a tank, when connecting and disconnecting a power bus bar to and from a GPT (instrument transformer) in the tank. SOLUTION: A connection conductor 16 connected to any bus bar conductor 2c is fixed in the interior of a tank 1 charged with insulation gas, a movable conductor 20 with one end insertable and removable is slidably inserted in the connection conductor 16, in a sliding contact 12 provided in a connection terminal 19 of a GPT 13, and an operating rod 22 connected to the movable conductor 20 through an insulating rod 21 is air-tightly inserted through a bearing blind patch 18.</p> |
