Compact-type hypid gas insulated switchgear (HGIS) three-row type power distribution unit based on 220 kV full combination single tubular column framework type

The utility model relates to a compact-type hypid gas insulated switchgear (HGIS) throw-row type power distribution unit based on a 220 kV full combination single tubular column framework type. A first group of buses and a second group of buses are arranged in parallel, a plurality of gaps are arranged in the crosswise direction of the two groups of buses, each gap is provided with three units by using the first group of buses and the second group of buses as boundaries, the three units are disposed at outer sides of the first group of buses and the second group of buses and between the first group of buses and the second group of buses, an incoming line framework and an outgoing line framework of the HGIS power distribution unit are disposed on a left side vertical type steel pipe and a right side vertical type steel pipe respectively, and the incoming line framework and the left side vertical type steel pipe are combined to form a single tubular column framework while the outgoing line framework and the right side vertical type steel pipe are combined to form a single tubular column framework. The power distribution unit provided by the utility model is advantageous in that lines of the same polarity are arranged in segments and at different sides, the problem of high cost of 220 kV outgoing lines in 500 kV and 220 kV transformer substations caused by cable frogging can be well solved, reverse outlet of half of the circuits and straight outlet of the other half of the circuits can be maximumly realized, the power distribution unit needs to be combined with circuit terminals and triple-circuit single pole is adopted, thereby realizing arrangement of the lines of the same polarity in segments and at different sides to the largest extent.
