METERING OUT FIT WITH SF6 GAS

摘要

The present invention relates to a meter out fit using insulation gas capable of removing a cause of a partial discharge by filling the insulation gas in a case and a bushing and ensuring an excellent insulation state to uniformly attenuate an electric field. The meter out fit using insulation gas includes: a case to receive a metering transformer and a metering current transformer; and a plurality of bushings including a primary rod coupled with the case to transfer external high voltage/large current to the metering transformer and the metering current transformer, a secondary rod which is mold-inserted in the bushing and which is to output small voltage/small current and an input voltage converted by the metering transformer and the metering current transformer therein. An inside of the case is filled with the insulation gas. The bushing includes a rod part in which the first rod and the second rod are inserted. Insulation gas injected into the case through an end of the rod part is naturally moved to the rod part to insulate the bushing.
