<p>PURPOSE:To reduce the overall size and to improve the insulation reliability, by arranging a common container on one side of an enclosed container for containing three-phase interrupting section and coupling grounded containers of respective main buses through insulating spacers. CONSTITUTION:A plurality of main buses 10a, 10b are arranged on one side face of a tubular enclosed container 1 for containing a three-phase interrupting section 2 and encapsulated with insulating gas. A common container 4 extending in the longitudinal direction is arranged between the main buses 10a, 10b and the enclosed container 1, then the common container 4 is coupled with the enclosed container 1. Furthermore, grounded containers of the main buses 10a, 10b are coupled each other through spacers 8, 9. A conductor 8a for connecting the main buses 10a, 10b with terminals at the interrupting section is arranged in the common container 4. A current transformer 6 may be contained in the common container 4.</p> |
