Abstract
A layout structure of 500 kV outdoor GIS distribution equipment comprises an upper overhead outgoing lead, a GIS (Gas Insulated Switch) outgoing lead sleeve, a down lead from upper overhead outgoing lead sleeve to GIS outgoing lead sleeve, a GIS circuit breaker, GIS buses and an outgoing lead framework, and is characterized in that the outgoing framework adopts a large root span steel tube herringbone column which just straddles above the a GIS, and the herringbone column and the GIS are arranged in a stacked manner; the GIS outgoing lead sleeve is arranged outside the outgoing lead framework; and the upper overhead outgoing lead is connected with the GIS outgoing lead sleeve via the down lead. According to the utility model, in a 500 kV circuit, distance between adjacent leads is 7 m; and in different circuits, distance between adjacent leads is 8 m, and spacing width of adjacent outgoing leads is 22 m. The layout structure is impact, saves occupied area and equipment investment, meets requirements on safe operation, is convenient to overhaul and maintain, and has better technical and economic benefits.
Description
Technical field
The utility model relates to 500kV ehv power transmission engineering design technology field, more particularly, relates to the outdoor GIS power distribution equipment of a kind of 500kV densification layout pattern.
Background technology
500kV is as the electric pressure of the key electrical network of China's superhigh pressure, and problems such as its technical advance and layout occupation of land obtain numerous designers' concern.The conventional layout pattern of the outdoor GIS power distribution equipment of 500kV is the inboard that GIS outlet sleeve pipe is arranged in outlet structure, and the employing wire jumper is connected between GIS outlet sleeve pipe and the upper strata overhead outlet.That above-mentioned conventional layout pattern, the interval width of 500kV overhead outlet mainly receive is alternate, limit phase wire jumper influences the phase ground distance of framework post.The windage yaw of consideration lead under different condition waved and safe clear distance, generally adopts 26 meters through calculating the interval width of whenever striding framework, and phase spacing is 7 meters, and apart from being 6 meters, floor space is big mutually.
The utility model content
The purpose of the utility model provides the GIS of the outdoor GIS power distribution equipment of a kind of 500kV of being applicable to and the novel compact arrangement form of outlet structure arranged superposed, also claims the OGA arrangement form.
For realizing above-mentioned purpose; The utility model provides the outdoor GIS power distribution equipment of a kind of 500kV arrangement; Comprise upper strata overhead outlet, GIS outlet sleeve pipe, upper strata overhead outlet to GIS outlet sleeve pipe downlead, GIS circuit breaker, GIS bus and outlet structure; It is characterized in that: outlet structure adopt big root open the steel pipe herringbone column stride stand on GIS directly over; Both arrange in an overlapping that spatially GIS outlet sleeve pipe is arranged in the outside of outlet structure, and the upper strata overhead outlet is connected through downlead with GIS outlet sleeve pipe.
The utility model 500kV loop inside conductor phase spacing is 7 meters, and the lead phase spacing is 8 meters between different circuit, and the outlet interval width is 22 meters; Arrange compactness, practice thrift and take up an area of, practice thrift equipment investment; Satisfy the safe operation requirement, repair and maintenance is convenient, has technology and economic benefit preferably.
Description of drawings
Fig. 1 is the utility model power distribution equipment plane of arrangement figure;
Fig. 2 arranges sectional drawing for the utility model power distribution equipment.
Embodiment
With reference to Fig. 1, Fig. 2, with big of 500kV open steel pipe herringbone column outlet structure 1 stride stand on GIS bus 2 and GIS circuit breaker 3 directly over, GIS outlet sleeve pipe 4 is arranged in the outside of outlet structure 1, upper strata overhead outlet 5 is connected through downlead 6 with GIS outlet sleeve pipe 4.
The 500kV power distribution equipment that adopts OGA to arrange, the outlet interval width is 22 meters, conventional the layout reduced 4 meters, takes up an area of thereby reduce power distribution equipment; This New O GA arranges that conventional 4 meters of the minimizings of arranging are whenever compared in each outlet main bus bar length at interval, and each outlet (main transformer inlet wire) septal fascicle bus is every to reduce 2 meters mutually, reduces investment outlay obviously.
