Background technology
At present, in the transformer station that the AIS of various electric pressures distribution is arranged, framework is a kind of indispensable structures.Using more general framework in conventional 220kVAIS transformer station has following several: one, main transformer framework, and high 15m, wide 15m is used to draw and connects main transformer sleeve pipe inlet wire (seeing Figure 1A and Figure 1B); Two, outlet structure, high 14m, wide 13m, the truck transom two ends are established the high steel column of 4m and are used to draw outlet and ground wire (seeing Fig. 2 A and Fig. 2 B); Three, double-deck framework, the high 15m of upper strata crossbeam, the high 12m of lower floor's crossbeam, wide 13m, upper strata crossbeam are hung strain insulator and are drawn and connect bus, and lower floor's crossbeam is hung the upside-down mounting insulator and connect vertical expansion isolating switch (seeing Fig. 3 A and Fig. 3 B); Other framework width, highly, pattern can adjust accordingly according to the actual requirements.
In recent years along with the raising of electrical network distribution technique requirement and the lifting of device fabrication level, the utilization of sealed type combined electrical apparatus (GIS) in 220kV transformer station more and more widely, GIS can significantly dwindle transformer station's land used, save valuable land resource, under the environment harsh conditions, still can keep long-term reliability and good shock resistance simultaneously.
The 220kVGIS outlet has cable and overhead outlet dual mode: cable outlet is drawn outlet outside the station by cable trough, and this outlet method is taken up an area of trifle province transformer station floor space, but the high construction of equipment cost is difficult; Overhead outlet is drawn outlet outside the station by framework, and this outlet method is bigger for guaranteeing that lead safety clear distance takes up an area of, but the low more easily construction of cost.
Summary of the invention
The utility model provides a kind of 220KV double space outlet structure that cooperates outdoor GIS to use, and can save cost, reduces difficulty of construction, also can reduce floor space.
The utility model proposes a kind of 220KV double space outlet structure, comprise herringbone column, main line frame, ground wire short column, the first turnover line interval and the second turnover line at interval.Wherein, main line sets up and places between the herringbone column.The first turnover line all is arranged at the main line frame at interval with the second turnover line at interval.The length of main line frame is 24.5m.Herringbone column's height is 12m.The height of ground wire short column is 7m.
In the utility model first turnover line has three lead hanging points respectively at interval with the second turnover line at interval, and first distance that passes in and out between two adjacent at interval with the second turnover line at interval lead hanging points of line is that 4.5m is to satisfy the electrical safety distance.
Distance between adjacent two lead hanging points in the distance between adjacent two lead hanging points in the utility model first turnover line interval and the second turnover line interval is 3.75m to satisfy the electrical safety distance.
Be connected to horizontal cross bar in the middle of the herringbone column in the utility model to guarantee herringbone column's stability.
The beneficial effects of the utility model are, the double space of traditional 220kV outlet structure is 26m, and the framework double space that the utility model proposes only is 24.5m, can compress the place size effectively.The framework height is 12m, and double space only uses two herringbone columns, can save framework steel consumption.And two times outlets of framework only need be arranged two ground wires protections, save the ground wire cost.

Embodiment
For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Please in the lump with reference to figure 4A, Fig. 4 B, Fig. 5 and Fig. 6, the 220KV double space outlet structure that the utility model provides comprises herringbone column 10, main line frame 11, ground wire short column 12, the first turnover the line 13 and second turnover line interval 14 at interval.
As shown in Figure 1, have two herringbone columns 10 in the present embodiment, it highly is 12m.The more common framework of this framework hangs down the 2m (see figure 2), has effectively saved framework steel consumption.Herringbone column 10 adopts isometrical steel-tube construction, adopts welding or bolt to connect.Herringbone column 10 centre is connected with horizontal cross bar 100, can strengthen its stability.
Main line frame 11 is arranged between the herringbone column 10, and its length is 24.5m.Twice GIS outwards draws overhead outlet by the double space outlet structure, common twice outlets interval beam overall 26m (see figure 2) in the prior art, this framework only is 24.5m, therefore can save the distance of 1.5m in the framework direction, thereby can shorten framework direction size generally in transformer station, reduce floor space.
Herringbone column 10 upper end is provided with ground wire short column 12, and in order to hanging ground-wire, it highly is 7m.Ground wire short column 12 can adopt single steel pipe.
In conjunction with Fig. 5 and Fig. 6, main line frame 11 is provided with the first turnover line, the 13 and second turnover line interval 14 at interval.In the utility model, the first turnover line, the 13 and second turnover line interval 14 at interval has three lead hanging point A, B, C respectively.As shown in Figure 6, limit phase conductor hanging point (the first turnover line at interval 13 A or the second turnover line 14 C) at interval is 2.5m apart from herringbone column 10, satisfy when windage yaw 220kV lead to the safe distance of currentless part 1.8m requirement.Isopic zone electric lead hanging point (A and B or B and C) spacing is not 3.75m, satisfies the not safe distance requirement of homophase 220kV live part 2.0m.Adjacent two outlets of twice outlets (the first turnover line, 13 C and second at interval passes in and out line 14 A at interval) spacing 4.5m also satisfies the electrical safety distance.
