<p>PURPOSE:To miniaturize a device, by arranging multiple breakers mutually in parallel and orthogonal to the center shaft of the first and second main bus bars. CONSTITUTION:The first breaker 3 is connected to the first main bus bar 1 through a disconnector 6, which is arranged on an extension of the center shaft of the breaker 3. The other end of the first breaker 3 is connected to a connecting bus bar 17 through a disconnector 7, while both ends of the second breaker 4 are respectively connected to connecting bus bars 16 and 17 through disconnectors 8 and 9 each. External circuit connection sections 20 and 21 are respectively provided between disconnectors 8 and 12 and between disconnectors 9 and 13. Disconectors 12 and 13 are respectively connected to bushings 14 and 15 through branch bus bars 18 and 19 each. Main bus bars 1 and 2 are arranged upward the disconnectors 8 and 9 and the connecting bus bars 16 and 17 are arranged upward the disconnectors 12 and 13 respectively. The third breaker 5 is connected in the same way as in the first breaker 3. With such an arrangement, the dimension between main bus bars 1 and 2 is shortened.</p> |
