A power capacitor (5) is electrically connected to the conductor while being disposed inside a compartment (3P) secured to the case (3A) and filled with a dielectric gas under pressure. The dielectric gas present in the compartment (3P) provides electrical insulation for the compartment relative to the power capacitor (5). In this way, electrical insulation of the gas-insulated line between the conductor (1A) and the case (3A) is maintained inside the compartment (3P) in which the power capacitor (5) and the conductor (1A) are electrically interconnected. This results in the gas-insulated line of the invention retaining small bulk and the ability to be used on the ground or buried.Field of SearchProcessesCoaxial or concentric type Gas filled Multiple conductor Impregnating compositions Gas filled Conduits, cables and conductors Impregnated insulation type Parallel or twisted conductors Plural chambers Movable Grounding switch Polyphase Compressing cylinder structure Polyphase With nozzle With throat region Shielding With gas flow means Operating mechanism structure or arrangement Air-current blowout Disconnect switch Self extinguishing With nozzle With gas blast means Contact structure Valve (e.g., blast valve or pressure relief valve) With nozzle Polyphase Fixed Plural switch connected in series Grounding switch Sealed chamber Identical units back-to-back Busbar Puffer piston With throat region Disconnect switch Contact structure With nozzle Disconnect switch Recirculating systems Piston structure Arc chute Operating mechanism structure or arrangement With throat region Arcing chamber Arcing chamber Exhaust port Contact structure Hybrid-type Resistance inserting With capacitor With capacitor CONDUCTOR ARRANGEMENTS OR STRUCTURE Gas insulated Electrical switchgear Truck type With interlock Drawer type With interlock Pivoted support means Busbar arrangements Gas insulated Liquid insulated With plural removable control units in housing With interlock Door or cover type Shutter type Gas insulated | |
