Description
Technical field
The invention belongs to high voltage power transmission and transforming field, and in particular to a kind of 330kV transformer stations GIS vertical wire outlet structure.
Background technology
With the high speed development of power grid construction, the scale of Ultra-high Voltage Substations engineering is increasing, is filled using regular distribution
It is more and more prominent to put the problem of arrangement floor space is big, land reserved resources wretched insufficiency, site expropriation of land, removal expense day
Benefit increase, especially in some urban central zones, land expropriation cost is in the situation substantially risen, and substation location selection is more and more tired
Difficulty, it is the problem that power grid construction must face to improve land resources utilization rate.For the high voltage distribution installation design of transformer station,
Gas-insulated metal-enclosed power distribution equipment (GIS) is a kind of intensive power equipment, and outdoor GIS device is generally maked somebody a mere figurehead out entirely
Line, A, B, C three-phase are horizontally arranged, in one line using herringbone gate framework outlet.Limited, become by outlet gate framework width
Power station totality outgoing line side width is not reduced because using GIS device, does not give full play to the advantage of GIS device characteristics of compact layout,
Showed more so in high altitude localities.Therefore, optimize the outlet method of GIS power distribution equipments, reduce outgoing line interval width, match somebody with somebody in GIS
During the line corridor design of electric installation, outlet structure and transmission line circuit, three-dimensional compact arrangement is considered, to greatest extent
Economization on land, the utilization rate in soil is improved, technical support can be provided for the construction of follow-up substation project, be significant.
The content of the invention
It is an object of the invention to for above-mentioned the problems of the prior art, there is provided a kind of 330kV transformer stations GIS's is vertical
Outlet structure, outgoing line interval width can be reduced, improve the utilization rate in soil, and then save equipment investment.
To achieve these goals, the technical solution adopted by the present invention is：
Including vertical wire outlet tower, A phases that vertical wire outlet tower has king-post and is stratified and set on by different height on king-post
Cantilever Beams, B phases Cantilever Beams and C phase Cantilever Beams, A phases Cantilever Beams, B phases Cantilever Beams and C phase the Cantilever Beams direction in top plan view
Staggeredly, the bottom of vertical wire outlet tower is provided with the outlet casing tube of corresponding different phase Cantilever Beams；Described A phases Cantilever Beams, B phases are encorbelmented
330kV A, B, C phase outlet is connected below beam and C phases Cantilever Beams respectively；Single Pin vertical wire outlets tower configuration two returns back out line, by A,
B, the Cantilever Beams of C phases make three-phase outlet spatially be arranged vertically.
The king-post of vertical wire outlet tower uses steel pipe type steel construction；A, the Cantilever Beams of B, C phase use triangle girder lattice type steel
Structure.
Hanging wire ring is provided with described A phases Cantilever Beams, B phases Cantilever Beams and C phase Cantilever Beams.
Described A phases Cantilever Beams, B phases Cantilever Beams and C phases Cantilever Beams connect A, B, C phase by strain insulator string and gone out respectively
Line, and A, B, C phase outlet are led to by outlet casing tube by suspension insulator.
Arrester and voltage transformer are provided with described vertical wire outlet tower, and arrester is parallel to outlet casing tube
Set.
Cat ladder is provided with the king-post of described vertical wire outlet tower.
Compared with prior art, the present invention has following beneficial effect：By by the upper, middle and lower three of vertical wire outlet tower
Stagger up and down before and after layer Cantilever Beams, arranged into " rice " font, three-phase conducting wire is spatially arranged vertically, arranged using cable space
The mode of row reaches the effect of compression outlet structure width.Two, which return back out line, shares a Pin vertical wire outlet towers, utilizes wire vertical row
The mode of row, outgoing line interval width can be effectively compressed, save the floor space of transformer station, reduce framework steel using amount, saved
Framework steel and foundation of civil work investment, while also can preferably coordinate with line side terminal tower wiring, line side is set
Meter is advantageously.Because interval width is reduced, and GIS main bus-bars are typically parallel to frame girder arrangement, GIS main bus-bars length also phase
It should reduce, save equipment investment.Terminating wire mode is different from conventional gate framework on vertical wire outlet tower of the present invention, also compresses
The length of GIS pipeline bus, has saved investment, after the vertical wire outlet scheme, is connected more suitable with circuit double back outlet
Freely.

Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, vertical wire outlet structure of the invention includes 330kV outlet casing tube 1, arrester 2 and vertical wire outlet tower；
Upper, middle and lower-ranking Cantilever Beams are provided with vertical wire outlet tower, are staggered up and down before and after Cantilever Beams, into " rice " font cloth
Put；Single Pin vertical wire outlets tower configuration two returns back out line, outlet casing tube 1 three it is perpendicular be longitudinally arranged, two return back out the A phases or C phases of line
Outlet is drawn by lower floor's Cantilever Beams, and the outlet of B phases is drawn by middle level Cantilever Beams suspension insulator wire jumper, C phases or A phase outlets
Drawn by upper strata Cantilever Beams, staggered before and after three-phase Cantilever Beams so that three-phase outlet is spatially arranged vertically.
Arrester 2 is parallel to outlet casing tube 1 and arranged.
The outlet casing tube 1 of every time GIS three-phase outlet of the invention is in longitudinally perpendicular arrangement, and 330kV three-phase outlet, which passes through, hangs

The king-post of vertical wire outlet tower of the present invention uses steel pipe type steel construction, and the Cantilever Beams of A, B, C phase use triangular beam lattice
Structure formula steel construction.Cat ladder is provided with the king-post of vertical wire outlet tower.A, the Cantilever Beams end set of B, C phase has hanging wire ring.
Referring to Fig. 2-3, as a result of vertical wire outlet tower, the mode of connection and conventional gate framework are different.330kV
The individual vertical of GIS power distribution equipments goes out transmission tower, if upper, middle and lower-ranking Cantilever Beams, is arranged into " rice " font.A, B, C three-phase outlet
Sleeve pipe is arranged in out the bottom of transmission tower Cantilever Beams end, and suspension insulator of the GIS outlets through beam end of encorbelmenting transits to outlet,
Three-phase conducting wire is arranged vertically.Because interval width is reduced, GIS main bus-bars length is also accordingly reduced, so as to save equipment investment.
After arrangement using vertical wire outlet tower, it is connected more smoothly with circuit outlet.Two return back out in line, and two return back out the C phases of line
The bottom for beam end of being encorbelmented in upper strata, B-phase are encorbelmented the bottom of beam end in middle level, and A phases are located at lower floor and encorbelmented the bottom of beam end
Portion, to meet the requirement of electrical safety clear distance, interval width is effectively compressed, has been saved floor occupying area.
The outlet method of vertical wire outlet structure of the present invention can reduce outgoing line interval width, reduce rolled steel dosage and basis is thrown
Money, and facade simple and beautiful is constructed and processed simple and convenient, saves the investment of GIS main bus-bars, has installation, maintenance, operation more
It the features such as convenient, safe and reliable, can be applied in engineering, and a new Scheme Choice is provided for outlet design.
Above content is to combine preferred embodiment further description made for the present invention, it is impossible to assert the present invention
Embodiment be only limitted to this, for person of an ordinary skill in the technical field, do not departing from present inventive concept
