<p>PURPOSE:To decrease a quantity of insulating gas sealed in the interior, with a length reduced in an axial direction of the container, by providing a disconnector within bushing. CONSTITUTION:In the bottom of bushings 21, 22, is air-tightly provided a container 10, under which a horizontal container 9 is connected through an insulating spacer 11. A disconnector 3 is provided in the bushing 21, 22, being connected to a breaker 4 provided in the container 9. In the container 10, are installed a current transformer 12 and earth disconnector 7, and installed an operating device 5, 8 for the disconnector 3 and the earth disconnector 7. In this way, only installation of the breaker 4 in the horizontal container 9 can reduce a length in an axial direction of the horizontal container 9, with a less quantity of insulating gas, sealed in the interior, made capable. And a distance, between the bushings, will never be increased more than a necessary insulation distance.</p> |
