摘要： 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.

摘要： PURPOSE:To provide a gas insulated switchgear which allows operation on the sound side while monitoring the gas for the circuit on the sound side and for a bus section unit with a main bus being sectioned through the bus section unit into the inspection/ maintenance side and the sound side at the time of maintenance/inspection of a bus machine. CONSTITUTION:A main bus connected with a plurality of lines and arranged with a bus section unit is housed in an enclosure 14 encapsulating an insulating gas. The enclosure is sectioned into a plurality of gas sections each coupled in parallel with a gas piping 5. A regulation valve 6 is provided between adjacent gas sections. The gas piping coupled with the gas section of a bus section unit 9 is coupled with a unit 7 for monitoring the pressure and density of gas. When the main bus is sectioned by the bus section unit 9 into the maintenance/inspection side and the sound side, the gas piping can also be sectioned into the maintenance/inspection side and the sound side by closing the regulation valve between the gas piping for the gas section of the bus section unit and the gas piping on the maintenance/inspection side. Since the gas section where the bus section unit is provided is coupled with the sound side, the sound side can be operated while monitoring the gas for the line on the sound side and for the bus section unit.
