<p>PURPOSE:To prevent equipment against the reduction of reliability and aggravation of economic efficiency, by enclosing multiple power circuits in a container. CONSTITUTION:A cable connection section 1 is connected to a power cable. The current flows from the cable connection section 1 to a power bus 16 through a disconnector 3, a breaker 9, and disconnectors 13 and 14. An instrument transformer 4 and current transformers 8 and 10 detect the conducting state of power circuits 31 and 32. Switches 2, 5 and 12 are closed in inspection as required. Each equipment is insulated and separated from a container 60 with compressed gas separation insulating spacers 6, 7, 11 and 15. A protective wall 17 prevents shorting caused by the formation of an arc across power circuits 31 to 32. Multiple power circuits can thereby be provided in a gastight container, so that the reduction of reliability and aggravation of economic efficiency of equipment can be prevented without increasing the number of parts, space for arrangement and compressed gas separated parts of gas sealing.</p> |
