Connect a phase conductor, complete A, B, C three-phase conducting wire outlet.
Described truss column the 3rd side increases by one and is combined cross-arm beam for wiring transition use.
It is provided with cat ladder on described truss column.
Described compound cross-arm beam is made up of two compound cross-arms, and two are combined the isosceles of cross-arm and truss column formation horizontal positioned
Triangle, hanging wire ring is fixed on two and is combined at cross-arm junction point.
Transformer station's outlet structure of the present invention uses each compound cross-arm beam and truss column to connect the double umbrella-shaped structures being combined into,
Arrange the mode of compound cross-arm up and down owing to truss column side have employed, with former horizontally disposed compared with, wire level can be saved
Requisite space, thus compress outgoing line interval width, save transformer station's floor space.Owing to cross-arm have employed composite, utilize
Its electric property, cancels strain insulator and suspension insulator, then can reduce framework height, be taken up space by former insulator chain and effectively release
Put, and save material investment.
To sum up, the invention have the advantages that
1, framework steel using amount reduces, and has saved framework steel and foundation of civil work investment.
2, the framework upper conductor mode of connection is different from conventional gate framework, and local is that dual-layer metal line is arranged vertically, effectively
Have compressed interval width, save floor occupying area.
3, have employed composite due to cross-arm, its electric property can be utilized, cancel strain insulator and suspension insulator, then may be used
Reducing framework height, taken up space effectively release by former insulator chain, and saves material investment.
4, after using umbellate form to be combined cross-arm scheme, it is connected more smoothly with circuit outlet.
5, framework facade is the most attractive in appearance, processes and constructs simple, saving the building time of engineering.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
Seeing shown in Fig. 1-1, outlet structure includes truss column 1, compound cross-arm beam 2, hanging wire ring 4, cat ladder 5 and other are supporting
Adnexa；Truss column 1 uses single-column latticed steel structure, and truss column 1 is provided with cat ladder 5, and compound cross-arm beam 2 uses Composite material
Material, truss column 1 is in an intermediate position, and both sides arrange compound cross-arm beam 2, and compound cross-arm beam 2 is by compound cross-arm and compound stay cable group
Conjunction forms, and the plural compound cross-arm beam about 2 being arranged on truss column 1 the same side is arranged, each compound cross-arm beam 2 one end with
The fixing connection of truss column 1, the other end are installed hanging wire ring 4 and are connected with truss column 1 tractive by compound stay cable, each compound cross-arm beam
2 are connected with compound stay cable 3 and truss column and to be combined into double umbrella-shaped structure.
Described truss column 1 both sides are respectively provided with a compound cross-arm beam 2 and two compound cross-arm beams 2, each compound cross-arm
Beam 2 connects a phase conductor, completes A, B, C three-phase conducting wire outlet.
As shown in Fig. 1-2 and Fig. 2-1, described truss column 1 the 3rd side increase by is combined cross-arm beam 2 to be made for wiring transition
With.
As shown in 2-2, described compound cross-arm beam 2 is made up of two compound cross-arms, and two are combined cross-arm forms water with truss column 1
The isosceles triangle of placing flat, hanging wire ring 4 is fixed on two and is combined at cross-arm junction point.
Why traditional outlet structure uses Steel structure door type frame, main reason is that three-phase conducting wire is horizontally arranged,
And composite is the most immature, it is the most economical for therefore using gate framework；In order to reach to simplify the purpose of framework, first should
Consider reduce the width of framework and drop low-built height.
Seeing Fig. 3 and Fig. 4, the three-phase conducting wire 9 being connected with GIS sleeve pipe 6 is respectively by after voltage transformer 7, spark gap 8 point
Not through three-phase composite cross-arm beam outlet, transformer station is additionally provided with GIS and carries LCP cabinet 10.Due to the fact that and have employed double umbellate form again
Closing framework, its mode of connection will be different with conventional gate framework.By comparing it can be seen that after using compound cross-arm, structure
Frame steel using amount reduces, and has saved framework steel and foundation of civil work investment；On framework, local is that dual-layer metal line is arranged vertically, effectively
Have compressed interval width, save floor occupying area；Owing to cross-arm have employed composite, its electric property can be utilized, cancel strain insulator
And suspension insulator, then can reduce framework height, taken up space effectively release by former insulator chain, and saves material investment；
After using double umbrella to be combined cross-arm scheme, it is connected more smoothly with circuit outlet；Compound cross-arm framework facade is the most attractive in appearance, processing and
Construction is simple, saves the building time of engineering.
Can be drawn by above-mentioned analysis, this kind of double umbellate forms are combined framework and have reduction outgoing line interval width, reduce steel
Consumption and infrastructure investment；Facade is the most attractive in appearance, constructs and processes simple and convenient；Saving insulator chain is invested；Install, overhaul, transport
The features such as row is more convenient, safe and reliable, can apply in engineering, and provide a new Scheme Choice for frame design.
Invention uses double umbellate form outlet, compressible outgoing line interval width, saves transformer station's floor space.Meanwhile, use again
After closing cross-arm, efficiently utilize the electric property of composite, save insulator chain and wire investment herein；Finally, by
In using single-column lattice outlet structure, can preferably coordinate with line side terminal tower wiring, line side is designed advantageously.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
The detailed description of the invention of the present invention is only limitted to this, for general technical staff of the technical field of the invention, is not taking off
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention by institute
