Abstract
The utility model provides a GIS distribution device arrangement structure that business turn over line framework merges which characterized in that: it is entering, is going out the many one sides of line number volume to merge the framework setting to draw forth the sleeve pipe one -to -one with the three -phase in GIS every return circuit, arrange the space department between the GIS main part equipment and the empty air jacket pipe of drawing forth, the three -phase air wire that advances, is qualified for the next round of competitions in number one side how in return circuit passes through insulator chain and hangs on each self -corresponding incorporation framework to the GIS who draws down and correspond draws forth sleeve pipe binding post and is connected, and the three -phase air wire in opposite side play, the every return circuit of inlet wire is drawn forth the sleeve pipe rather than corresponding GIS and is arranged according to upper and lower connection on spatial position, and also hangs on the incorporation framework through insulator chain, draws down to draw forth sleeve pipe binding post with the GIS that corresponds and be connected. Because GIS draws forth the sleeve pipe underlaps on the plane with the framework that advances, is qualified for the next round of competitions, GIS draws forth the sleeve pipe terminal needn't set up the wire jumper with being connected of overhead wire on the framework, and the framework width that consequently advances, is qualified for the next round of competitions can be based on the condition of arranging suitably to be reduced. Reduce vertical size of high voltage power distribution device by a wide margin, saved the occupation of land, also reduced the basis and the steel of framework simultaneously.
Description
Technical field
This utility model relates to one and is suitable for use with power plant and transformer station's high voltage distribution installation of outdoor type gas insulation metal seal combined electrical apparatus (GIS), especially suitable to the high voltage distribution installation of 66kV and above.
Background technology
Outdoor type GIS device body characteristics of compact layout, floor space is little, but GIS typically each need to arrange large-sized into and out of line framework to meet the requirement of charged clear distance, make the floor space of high voltage distribution installation be forced to increase.Use conventional into and out of the line architecture plan of establishment time, the framework quantity of high voltage distribution installation (GIS) is determined plus transmission line circuit number by wire inlet loop number, has how much back into, outlet, it is necessary to arrange how many frameworks.As a example by 500kV GIS, the equipment at interval, each loop laterally takes up an area size and only has 5 meters, and the hanging wire framework in each line loop laterally takes up an area size 30 meters, longitudinal size about 6 meters.Use if able to inlet wire framework and outlet structure are merged, then the framework that just can at least reduce inlet wire or outlet side takes up an area space.Such that it is able to the longitudinal direction that GIS is greatly shortened takes up an area size, reduce basis and the steel construction investment of framework.
Utility model content
This utility model is the scheme merged into and out of line framework during high voltage distribution installation employing outdoor type GIS, it is adaptable to electric pressure is 66kV ~ 1000kV, uses the high voltage distribution installation of the various wiring patterns of outdoor type GIS.
For achieving the above object, this utility model provides the GIS power distribution equipment arrangement that a kind of line framework merges, it is characterized in that: merge framework and be arranged on into and out of the many side of line quantity, and the three-phase extraction tube one_to_one corresponding in loop each with GIS, it is arranged in the gap between GIS main equipment and the casing air of extraction；The many side of feeder number hangs on each self-corresponding merging framework into and out of the three-phase aerial condutor of line by insulator chain, and draw lower and corresponding GIS extraction tube binding post connection, the GIS extraction tube that opposite side goes out, the three-phase aerial condutor in the every loop of inlet wire is corresponding on locus by being vertically connected with layout, and also hung on merging framework by insulator chain, draw lower and corresponding GIS extraction tube binding post connection.
Owing to GIS extraction tube and merging framework are the most overlapping, GIS extraction tube terminal need not arrange wire jumper merging with the connection of aerial line on framework, and therefore merging framework width suitably can reduce according to deployment scenarios.Line framework is merged into one and merges framework use, drastically reduce the area the longitudinal size of high voltage distribution installation, save occupation of land, decrease basis and the steel of framework simultaneously.Electric pressure is the highest, merges the economic benefit using line framework to be brought and social benefit is the most obvious.
Accompanying drawing explanation
Fig. 1 is that 500kV double bus scheme outdoor GIS omits outlet structure site plan；
Fig. 2 is 500kV, and 3/2 breaker connection outdoor GIS omits inlet wire framework layout drawing；
Fig. 3 is that Fig. 1 line is spaced sectional drawing.
In figure, 1 for merging framework, and 2 is GIS main bus-bar, and 3 is GIS outlet terminal, and 4 is GIS inlet wire terminal, and 5 is outlet circuit, 6 is inlet wire wire, and 7 is strain insulator string, and 8 is maintenance road, and 9 is #1 outlet, 10 is #2 outlet, and 11 is #1 main transformer inlet wire, and 12 is standby change inlet wire, and 13 is #2 main transformer inlet wire.
Detailed description of the invention
With reference to Fig. 1, eliminating #1 outlet and the framework of #2 outlet, have adjusted the GIS terminal position of #1 outlet and #2 outlet, make the corresponding phase of #1 outlet and #1 main transformer inlet wire overlap, the corresponding phase of #2 outlet and standby change inlet wire overlaps.#1 outlet and #2 outlet are hung on the merging framework of #1 main transformer inlet wire and standby change inlet wire by strain insulator string.
With reference to Fig. 2, eliminate inlet wire framework, #1 main transformer inlet wire and #2 main transformer inlet wire are hung on merging framework by strain insulator string.
With reference to Fig. 3, #1 main transformer inlet wire and #1 outlet are arranged in an interval simultaneously, and #1 main transformer inlet wire and #1 outlet are used in conjunction with same merging framework.
