<p>PURPOSE:To reduce a floor space to facilitate an inspection by providing a cable connection on the top or bottom surface of a closed vessel, by connecting respective terminals of cable bushing, circuit breaker, disconnector and bus bushing through a conductor in the vessel to constitute a main circuit and by enclosing an insulating gas in the vessel. CONSTITUTION:A bus bushing 23 is gastightly provided to pass through both openings 14d in the lower part of the front of a closed vessel 14, a bus conductor 24 for connecting bus bushings 23 is mounted from the opening 14c of the central port of the front, and a connecting conductor 32 is connected therewith. A disconnector 20 is inserted from the opening 14c of the vessel 14, the connecting conductor 32 is connected with the disconnector 20, and a connecting conductor 29 is fixed on a support stand 30 and connected with the disconnector 20. A cable bushing is provided to pass through the opening 14a in the top surface of the vessel 14, and a connecting conductor 27 is supported by and connected with the terminal of a bushing 15 from an opening 14b. The connecting conductors 27, 29 of main circuit terminals 19a1, 19a2 are connected with disconnectors 29, 30 and an insulating gas is enclosed in the vessel 14. Thus, it is possible to reduce a floor area to facilitate an inspection.</p> |
