<p>PURPOSE:To reduce the area of installation when combining gas-insulated double buses with gas-insulated circuit breakers and disconnecting switches, by combining four gas disconnecting switches for two buses with connecting gas buses and making the form of the assembly oblong. CONSTITUTION:The connecting gas buses 9 and the four gas disconnecting switches 5-8 for two buses are located in the oblong form perpendicularly to overhead buses. Bushings 4 are provided between the bus-side gas disconnecting switches 5, 6 and 7, 8. The opposite disconnecting switches 5, 7 and 6, 8 are connected to each other through the connecting gas buses 10, 11 and connected to line-side gas disconnecting switches 3 and bushings 4 through line-side circuit breakers 1. Since the bus-side disconnecting switches are connected to the circuit breakers through the connecting gas buses, the area of installation and the height of the overhead buses are reduced. Therefore, the power transmission/reception device is made compact.</p> |
