<p>Main buses 1 and 2 which are to be sectioned into two on the respective axes are disposed on two parallel straight lines facing each other, further at the outside of the bus sectioning portions for the main buses 1 and 2 auxiliary buses 6 are disposed in parallel with the respective axes of the corresponding main buses, one end of the auxiliary bus is connected to the corresponding end of the main bus by a branching bus 7 along which a main bus connected potential transformer 11 and a main bus use earthing switch 13 are provided, further, a branching bus 9 led out from one of leading out portions for a circuit breaker 5 extends over the auxiliary bus 6 and is connected to the corresponding main bus via a disconnecting switch 8a and at the midway of a branching bus connecting between the disconnecting switch 8a and the main bus a main bus connected potential transformer 10 and a main bus working use earthing switch 12 are provided. Whereby, because of the concentrated disposition of the main bus connected ptential transformers and the main bus working use earthing switches in the respective bus sectioning units, the entire arrangement structure of the gas insulated switchgear device is rationalized and compacted, thereby the cost therefor is improved. <IMAGE></p> |
