Description
Technical field
The present invention relates to power equipment arrangement and outlet structure, specifically a kind of 220 kilovolts of outdoor GIS double-dragonfly-typoutlet outlet wire arrangement structure.
Background technology
Along with the development of electrical network, transformer station's quantity is in continuous increase, land reserved resources wretched insufficiency, site expropriation of land, removal expense increase day by day, special in some urban central zones, land expropriation cost is in the situation that obviously rises, and substation location selects more and more difficulty, and it is current problem demanding prompt solution that transformer station saves the area.
At present, GIS device is a kind of intensive power equipment, improve conventional equipment arrange dispersion floor space large, failure rate is high, Installation and Debugging and plant maintenance workload large, the shortcomings such as long construction period, there is characteristics of compact layout, exempt from the advantage that (lacking) safeguards, operational reliability is high, land seizure can be saved by high degree, decrease the expensive front-end fee such as expropriation of land, removal, reparation and use, meet the fundamental state policy that China saves the area, be widely used.
GIS device has indoor layout and outdoor layout two kinds, and relative to indoor GIS scheme, outdoor GIS generally adopts full overhead outlet, owing to not having the restriction of building, can give full play to the feature of GIS flexible arrangement, thus plays the effect of saving and taking up an area.But current conventional outdoor GIS generally adopts the horizontal word order of A, B, C three-phase outlet casing tube, framework adopts herringbone gate framework level in one line, sleeve pipe phase spacing is generally 3-3.5 rice, wire spaced apart 3.75 meters, while lead wired-AND gate structure centre-to-centre spacing 2.75 meters, State Grid Corporation of China's modular design suggested design 220 KV distribution device gate framework minimum widith is 12m.Due to by the restriction of outlet door frame width, make the overall outgoing line side size of transformer station not because adopting GIS device and reduce.
Therefore, need to optimize GIS device outlet arrangement, reduce outgoing line interval width, power distribution equipment is arranged more compact, thus Economization on land to greatest extent, improve the utilance in soil.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming the existence of above-mentioned prior art, a kind of 220 kilovolts of outdoor GIS double-dragonfly-typoutlet outlet wire arrangement structure are provided, it improves outdoor GIS outgoing line interval arrangement and optimizes, reduce the overall outgoing line side lateral dimension of transformer station, floor space in compression transformer station enclosure wall, saves electric outgoing line corridor.
For this reason, the present invention adopts following technical scheme: a kind of 220 kilovolts of outdoor GIS double-dragonfly-typoutlet outlet wire arrangement structure, comprise at least two GIS outgoing line intervals and at least one outlet structure, at least two described GIS outgoing line intervals are connected 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 formed 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 lays respectively at the outlet cross-arm composition of steel pipe pole both sides by two, 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 in horizontal positioned, the outlet casing tube that described three phase lines are vertically arranged by three respectively draws, be connected with the outer end hanging wire point of the outlet cross-arm be positioned at above outlet casing tube respectively by wire again, by two GIS outgoing line intervals with an outlet structure with the use of forming the vertical overhead outlet of upper, middle and lower-ranking double back.
The present invention simplifies outdoor GIS power distribution equipment outlet structure, and lateral dimension compresses; Under horizontal range between adjacent outgoing conductor meets the prerequisite of electrical safety requirements, decrease the overall outgoing line side lateral dimension of transformer station, have compressed floor space in transformer station's enclosure wall, saved electric outgoing line corridor.
As improving further and supplementing technique scheme, the present invention takes following technical measures:
Further, 180 degree of angles are formed between two outlet cross-arms in described middle level; The upper strata outlet cross-arm drift angle that misplaces with the outlet cross-arm of middle level homonymy is respectively preferably 45-55 degree (most preferably being 52 degree), forms 70-90 degree angle between two outlet cross-arms on upper strata; Lower floor's outlet cross-arm misplace with the outlet cross-arm of middle level homonymy respectively drift angle be also preferably 45-55 degree (most preferably being 52 degree), also form 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 longitudinal word order, can reduce the overall outgoing line side lateral dimension of transformer station further.
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 being 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 being 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 outgoing conductor.
Further, one is provided with for hanging the lightning conducter cross-arm of lightning conducter directly over the outlet cross-arm being positioned at upper strata.
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, ensure that outgoing conductor is in the protection range of lightning arrester.
Further, two outlet cross-arms in every layer of outlet cross-arm are that axle is symmetrical set with steel pipe pole, and make the both sides uniform force of steel pipe pole, structure is more stable.
The outgoing line side lateral dimension of outdoor GIS power distribution equipment compresses by the present invention, because lightning arrester is built-in, singly returns back out line interval width and can be reduced to 6 meters, double back outgoing line interval width can be reduced to 12 meters, significantly can reduce floor space, reduce land expropriation cost, reduce 220kV GIS bus length, reduce GIS cost, outlet structure is succinct, and steel material is saved, and therefore overall investment is far smaller than conventional GIS power distribution equipment arrangement, the area that particularly soil land expropriation cost is high, advantage is more obvious.
