Main transformer inlet wire structure

The utility model discloses a main transformer inlet wire structure; the main transformer and 220kVGIS equipment are connected in a cross-path-pipe bus mode, and the cross-path-pipe bus is supported by a 220kV inlet wire lightning arrester and supporting insulators; the main transformer and 110kVGIS equipment are closely arranged and are connected in an oil gas sleeve pipe mode; the technical scheme has the following advantages: 1, layout scheme is clear and beautiful, equipment external insulation porcelain sleeve is less, environment endurance is strong, and safety is high; 2, distance between transformation buildings is reduced, and occupation area is saved; 3, 220kV lead wire height is reduced; 4, height of 220kV and 110kV equipment and main variation line is reduced, lightning conducter with height of 15m can be erected between two power distribution buildings, so direct lightening prevention protection of all electric equipment in the two buildings is realized; and four independent lightning rods with h
