Abstract
The present invention discloses a kind of 110 kilovolts of outdoor GIS device structures. Conventional 110kVGIS device structure go out the thread casing horizontal word order of many employings, namely go out thread casing setting parallel with bus, make the horizontal size of GIS device outgoing line side still relatively big, be also not suitable for mating use with the outlet structure after the improvement of some structures. It is a feature of the present invention that, the bottom of described three points of branch casings is arranged on lower base and the distribution in emitting shape, the inner chamber of three points of branch casings communicates with the inner chamber of lower base respectively, three points of branch casings in longitudinal word order and the plane orthogonal at three points of branch casing places in bus. The structure of GIS device is optimized by the present invention, have compressed the horizontal size of GIS device outgoing line side further, also makes it be applicable to the outlet structure after improving with some structures and mates use, to reduce the horizontal size of the overall outgoing line side of substation.
Description
Technical field
The present invention relates to power equipment, specifically a kind of 110 kilovolts of outdoor GIS device structures.
Background technology
Basic farmland should be dodged when current substation location is selected, take mountain region, hillside fields or wasteland as far as possible. When basic farmland cannot be dodged, prioritizing selection is answered to take up an area few technical scheme when selection technique scheme, when Economic contrast is with, when saving the area contradictory, Economic contrast should be obeyed and be saved the area.
Along with the development of electrical network, substation's quantity is in continuous increase, land reserved resources wretched insufficiency, its land use selection is more and more difficult, site expropriation of land, removal expense increase day by day, at flourishing urban central zone, land expropriation cost is rising situation, substation as much as possible Economization on land be current problem demanding prompt solution.
GIS device is a kind of intensive power equipment, improve that conventional equipment arranges that dispersion floor space is big, failure rate height, installation and debugging and maintenance of the equipment workload big, the shortcomings such as long construction period, have and exempt from the advantage that (lacking) safeguards, serviceability is high, can save land seizure greatly. Meet the fundamental state policy that China saves the area, decrease the expensive front-end fee such as expropriation of land, removal, reparation and use.
Relative to indoor GIS scheme, outdoor GIS generally adopts full overhead outlet, owing to not having the restriction of buildings, it is possible to give full play to the feature of GIS flexible arrangement, thus plays the effect saved and take up an area. Conventional 110kVGIS device structure go out the thread casing horizontal word order of many employings, namely go out thread casing setting parallel with bus, make the horizontal size of GIS device outgoing line side still relatively big, be also not suitable for mating use with the outlet structure after the improvement of some structures.
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 110 kilovolts of outdoor GIS device structures are provided, the structure of GIS device is optimized by it, the horizontal size of compression GIS device outgoing line side further, also makes it be applicable to the outlet structure after improving with some structures and mates use.
For this reason, the present invention adopts following technical scheme: a kind of 110 kilovolts of outdoor GIS device structures, comprise the GIS outgoing line interval that at least two buses by an arranged transversely connect, three phase lines in each GIS outgoing line interval enter in the lower base of an erect-type outlet sleeve part, it is divided in three couplings by being positioned at three points of branch casings above lower base again, it is characterized in that, the bottom of described three points of branch casings is arranged on lower base and the distribution in emitting shape, the inner chamber of three points of branch casings communicates with the inner chamber of lower base respectively, three points of branch casings in longitudinal word order and the plane orthogonal at three points of branch casing places in bus.
Further, the top spacing of contiguous branch sleeve pipe is 1.2-1.8 rice, it is ensured that the electric safe distance between outlet wire.
Further, three points of described branch casings and lower base are one-body molded, facilitate the processing of outlet sleeve part.
Further, three phase lines enter in vertical part in by the horizontal portion of GIS outgoing line interval, complete 90 degree of rotations of three phase line entirety; Before three phase lines enter three points of branch casings respectively, the position of A phase line keeps not moving, the position of B phase line and C phase line completes exchange, guarantee that B phase line enters middle point branch casing, A, C phase line enters point branch casing (A, C phase line can be exchanged, and namely A phase line enters point branch casing on the left side or point branch casing on the right) on both sides.
The present invention, by horizontal for the outgoing line side of outdoor GIS device structure size compression, singly returns back out line interval width and can be reduced to 3.75 meters, and double back outgoing line interval width can be reduced to 7.50 meters, can significantly reduce floor space, reduce land expropriation cost, reduce 110kVGIS bus length, reduce GIS cost; The present invention is applicable to the outlet structure after improving with some structures (such as round trip flight dragonfly formula outlet structure, all outlet cross-arms of its side hang the projection of line point also in longitudinally in one line) coupling use, the horizontal size that minimizing GIS device structure and outlet structure take further, thus decrease the horizontal size of the overall outgoing line side of substation.

Embodiment
Below in conjunction with specification drawings and specific embodiments, the present invention is further illustrated.
The outdoor GIS device structure of 110 kilovolts as Figure 2-3, four GIS outgoing line intervals 1 are connected by the bus 2 of an arranged transversely, three phase lines in each GIS outgoing line interval enter in the lower base 31 of erect-type outlet sleeve part 3, it is divided in three couplings by three points of branch casings 32,33,34 being positioned at above lower base again, finally it is connected with the extension line point of outlet cross-arm outer end on outlet structure by outlet wire. The bottom of described three points of branch casings 32,33,34 is arranged on lower base 31 and the distribution in emitting shape, the inner chamber of three points of branch casings 32,33,34 respectively inner chamber with lower base 31 communicate, three points of branch casings in longitudinal word order and the plane orthogonal at three points of branch casing places in bus 2. The top spacing of contiguous branch sleeve pipe is 1.2-1.8 rice. Three points of described branch casings and lower base are one-body molded.
It may be seen that three phase lines enter in vertical part in by the horizontal portion of outgoing line interval from Fig. 4-5, complete 90 degree of rotations of A, B, C tri-phase line entirety;As can be seen from Fig. 5-6, before three phase lines enter three points of branch casings respectively, the position of A phase line keeps not moving, the position of B phase line and C phase line completes exchange, guarantee that B phase line enters middle point branch casing, A, C phase line enters point branch casing (A, C phase line can be exchanged, and namely A phase line enters point branch casing on the left side or point branch casing on the right) on both sides.
The above is only the better embodiment of the present invention, not the structure of the present invention is done any restriction in form. Every any simple modification, equivalent variations and modification above embodiment done according to the technical spirit of the present invention, all falls within the scope of protection of the present invention.
