Abstract

PURPOSE:To prolong the saturation period of gas in the bushing by connecting a leader tube provided at the intermediate flange section direct to a conservator including the body of the transformer in a through connection bushing between the transformer and the SF6 gas equipment. CONSTITUTION:An intermediate flange 17 is provided between a tank pot 9 of the transformer tank 1 and the pocket 11 of an SF6 gas equipment to house a central conductor 15 electrically connecting both the components and the insulator 16. A valve 25, a voltage-releasing device 24 and the like are provided at the tip of a leader tube 23 provided on the intermediate flange section 17 while directly connected to the conservator of the transformer by way of the gas detector 26 and the piping 27. The terminals 18 and 19 insulated and supported through insulated cylinders 13 and 14 are provided across the central conductor 15 and connected to lead wires 4 and 22 of both the equipments.
