<p>PROBLEM TO BE SOLVED: To compactify a switch by interconnecting main bus bars which are divided into two, and composing a circuit capable of being connected to either of the main bus bars of the minimum number of equipment. SOLUTION: Main bus bars 1a, 1b and an auxiliary bus bar 1c are disposed so that each other's axes are in parallel and that the end parts overlap each other. Respective bus bar disconnecting switches 4a, 4b are connected to the position where the respective bus bars 1a, 1b overlap each other, and a bus bar sectioning circuit breaker 9a for interconnecting the min bus bars 1a, 1b is connected to the disconnecting switches 4a, 4b. Also, respective disconnecting switches 4c, 4d are disposed in the position where the auxiliary 1c and the respective main bus bars 1a, 1b overlap each other, the main bus bars 1a, 1b and the auxiliary bus bar 1c are connected to each other through the respective disconnecting switches 4c, 4d. Furthermore, an external connection circuit breaker 9b is connected to the auxiliary bus bar 1c.</p> |
