<p>PROBLEM TO BE SOLVED: To provide a transforming facility which is capable of reducing the area of facility site with a gas insulated switchgear and connecting them directly. SOLUTION: A gas insulated switchgear 2 made up of bushings 3, disconnectors 4, grounding switches 5, breakers 6 and connecting buses 7, 8 is provided on the top surface of a transformer 1. Outlets 10 to 12 of a three- phase main circuit are connected to the breakers 6 via oil-gas bushings 9 provided on the outlets 10 to 12, connecting buses 8 branched in a traverse direction on the top parts of the oil-gas bushing 9 and connecting buses 7 connected to the bottom parts of the breakers 6 and branched in the traverse direction. The grounding switches 5, the disconnectors 4 and the gas bushings 3 are connected to the top parts of the breakers 6. The gas insulated switchgear 2 is fixed to the fixing bases 13 of the transformer 1 by a frame 15.</p> |
