CONSTITUTION:Main bus bars 1, 2 are arranged almost parallelly to each other, and breakers 3 to 5 are respectively arranged mutually parallelly between the main bus bars 1, 2 so that the breakers are placed orthogonal to the center line in a lengthwise direction of the main bus bars 1, 2. Connection bus bars 16, 17 are arranged parallelly to each other inside the main bus bars 1, 2. Disconnecting switches 6 to 11 are arranged in upper parts of the breakers 3 to 5. The disconnecting switches 6, 11 are positioned respectively between the main bus bars 1, 2 and between the breakers 3, 5 and arranged in a manner wherein the center line in a lengthwise direction of the disconnecting switch is placed in parallel to the center line in a lengthwise direction of the breaker. The disconnecting switches 7 to 10 are positioned between the connection bus bars 17, 16 and between the breakers 3, 5 and arranged in a manner wherein the lengthwise directional center line of the disconnecting switch is placed orthogonal to the lengthwise directional center line of the breaker.</p> |
