<p>PURPOSE: To miniaturize a gas insulation substation which effectively utilizes a building space for the substation by arranging all gas insulators at a high- voltage side on a first floor and all main buses at the high-voltage side on a floor which is different from the first one. CONSTITUTION: An equipment 7 at the road side from all gas-blast circuit- breakers 2 and 2' at the high-voltage side of a gas insulation switcher is arranged on the same floor surface as the gas-blast circuit-breakers 2 and 2' and a first floor and a bus side equipment 8 is arranged on an upper floor. Then, the line side equipment 7 and the bus side equipment 8 are connected by the gas-blast circuit-breakers 2 and 2' which also play the role of a tie line bus. Further, a main bus 12 for connecting through an upper-floor floor surface is withdrawn toward a lower floor and is connected to a gas-blast circuit-breakers 10 for transformer and hence a transformer 4, thus effectively utilizing a building space for substation and miniaturizing a gas insulation substation.</p> |
