At present, GIS equipment is a kind of intensive power equipment, improved that conventional equipment arrange to disperse that floor space is large, failure rate is high, Installation and Debugging and the plant maintenance workload large, the shortcomings such as long construction period, have advantages of characteristics of compact layout, exempt from (lacking) safeguard, operational reliability is high, greatly degree is saved land seizure, has reduced the expensive front-end fee use such as expropriation of land, removal, reparation, meet the fundamental state policy that China saves the area, be widely used.
GIS equipment has two kinds of indoor layout and outdoor layouts, and with respect to indoor GIS scheme, outdoor GIS is general adopts full overhead outlet, due to the restriction that there is no building, can give full play to the characteristics of GIS flexible arrangement, thereby play the effect of taking up an area of saving.But conventional outdoor GIS generally adopts A, B, the horizontal word order of C three-phase outlet casing tube at present, framework adopts miter gate's type framework level in one line, the sleeve pipe phase spacing is generally 3-3.5 rice, 3.75 meters of wire spaced apart, 2.75 meters of wired-AND gate structure centre-to-centre spacing are led on limit, and State Grid Corporation of China's modular design suggested design 220 KV distribution device gate type framework minimum widiths are 12m.Due to the restriction that is subjected to outlet door frame width, make the overall outgoing line side size of transformer station not because adopting GIS equipment to reduce.
Therefore, need to optimize GIS equipment outlet arrangement, reduce the outgoing line interval width, arrange power distribution equipment more compact, thereby save to greatest extent soil, improve the utilance in soil.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect that above-mentioned prior art exists, a kind of 220 kilovolts of outdoor GIS round trip flight dragonfly outlet arrangements are provided, it improves and optimizes outdoor GIS outgoing line interval arrangement, reduce the overall outgoing line side lateral dimension of transformer station, floor space in compression transformer station enclosure wall, save electric outgoing line corridor.
For this reason, the utility model adopts following technical scheme: a kind of 220 kilovolts of outdoor GIS round trip flight dragonfly outlet arrangements, comprise at least two GIS outgoing line intervals and at least one outlet structure, described at least two GIS outgoing line intervals connect by the bus of horizontally set, it is characterized in that, the six roots of sensation outlet cross-arm that described outlet structure comprises an erect-type steel pipe pole and forms on steel pipe pole, all outlet cross-arms are all vertical with steel pipe pole, described six roots of sensation outlet cross-arm is presented, in, lower three layers of distribution, every layer forms by two outlet cross-arms that lay respectively at the steel pipe pole both sides, and the outlet cross-arm of one deck spatially all misplaces with other same side output terminal cross-arms of two layers arbitrarily,
Each GIS outgoing line interval has three phase lines that are horizontal positioned, described three phase lines are drawn by three vertical outlet casing tubes that arrange respectively, by wire, be connected with the outer end hanging wire point of the outlet cross-arm that is positioned at the outlet casing tube top respectively again, be used in conjunction with and form the vertical overhead outlet of upper, middle and lower-ranking double back by two GIS outgoing line intervals and an outlet structure.
The utility model is simplified outdoor GIS power distribution equipment outlet structure, the lateral dimension compression; In the horizontal range between adjacent outlet wire, meet under the prerequisite that electrical safety requires, reduced the overall outgoing line side lateral dimension of transformer station, compressed floor space in transformer station's enclosure wall, saved electric outgoing line corridor.
As the further of technique scheme improved and supplement, the utility model is taked following technical measures:
Further, between two of described middle level outlet cross-arms, form 180 degree angles; Outlet cross-arm in upper strata is preferably 45-55 degree (most preferably being 52 degree) with the outlet cross-arm dislocation drift angle of middle level homonymy respectively, between two outlet cross-arms on upper strata, forms 70-90 degree angle; Lower floor's outlet cross-arm also is preferably 45-55 degree (most preferably being 52 degree) with the outlet cross-arm dislocation drift angle of middle level homonymy respectively, also forms 70-90 degree angle between two outlet cross-arms of lower floor.Adopt the outlet structure of above-mentioned setting, make the compact overall structure of outlet structure.
Further, the lightning arrester of described GIS outgoing line interval is built-in, and a phase line is perpendicular to bus, and the other two linearly extension of phase line bendings again, make three outlet casing tubes be vertical word order, can further reduce the overall outgoing line side lateral dimension of transformer station.
Further, the level interval of adjacent phase line is 0.5-0.7 rice, and the spacing of adjacent casing is 3.0-3.5 rice, and the center of outlet structure and the spacing of outlet casing tube are 3.3-3.5 rice, guarantee the requirement of electrical safety distance.
Further, the fore-and-aft distance that is positioned at three outlet cross-arm hanging points of homonymy is 3.5-3.8 rice, it is 9-9.5 rice that the hanging wire that is positioned at the outlet cross-arm of lower floor is selected apart from ground level, and the difference in height between the adjacent outlet cross-arm of homonymy is 5.0-5.5 rice, guarantees the safe distance between the outlet wire.
Further, be positioned at upper strata the outlet cross-arm directly over be provided with one be used to hanging the lightning conducter cross-arm of lightning conducter.
Further, described lightning conducter cross-arm and the distance of the discrepancy in elevation between the outlet cross-arm on upper strata are preferably 4-4.5m, guarantee that the outlet wire is in the protection range of lightning arrester.
Further, two outlet cross-arms in every layer of outlet cross-arm be take steel pipe pole as axle is symmetrical set, and make the both sides of steel pipe pole stressed evenly, and structure is more stable.
The utility model compresses the outgoing line side lateral dimension of outdoor GIS power distribution equipment, because lightning arrester is built-in, singly return back out the line interval width and can be reduced to 6 meters, double back outgoing line interval width can be reduced to 12 meters, can significantly reduce floor space, reduce land expropriation cost, reduce 220kV GIS bus length, reduce the GIS cost, outlet structure is succinct, and steel material is saved, so overall investment is far smaller than conventional GIS power distribution equipment arrangement, the high area of soil land expropriation cost particularly, advantage is more obvious.
