<p>PURPOSE: To promote compounding of machines by shortening the longitudinal length of main bus and reducing the occupation area of bus section line. CONSTITUTION: A circuit breaker 3 and first and second disconnectors 4, 21 are arranged in U-shape through connection buses 9a-9c and an extension bus 22 between first and second buses 1, 2 arranged on a line while facing the end parts each other. The circuit breaker 3 is arranged toward the direction intersecting the first bus 1 perpendicularly and connected with the first main bus through the first disconnector 4. The extension bus 22 is disposed at the end part of the second main bus 2 while being bent perpendicularly from the end part of the second main bus 2 and arranged in parallel with the circuit breaker 3. The extension bus 2 is connected, at the lower part thereof, with a voltage transformer 13 for bus. The second disconnector 21 incorporates a ground switch 7 for inspecting the circuit breaker and a ground switch 15 for main bus.</p> |
