Described truss column both sides arrange a compound cross-arm beam and two compound cross-arm beams respectively, and each compound cross-arm beam connects a phase conductor, completes the outlet of A, B, C three-phase conducting wire.
Described truss column the 3rd side increases by a compound cross-arm beam and uses for wiring transition.
Described truss column is provided with cat ladder.
Described compound cross-arm beam is made up of two compound cross-arms, and two compound cross-arms and truss column form the isosceles triangle of horizontal positioned, and hanging wire ring is fixed on two compound cross-arm tie point places.
Transformer station of the present invention outlet structure adopts two umbrella-shaped structures of each compound cross-arm beam and the synthesis of truss column Connecting groups, because truss column side have employed the mode of arranging compound cross-arm up and down, compared with former horizontal arrangement, the horizontal requisite space of wire can be saved, thus compression outgoing line interval width, save transformer station's floor space.Because cross-arm have employed composite material, utilize its electric property, cancel strain insulator and suspension insulator, then can reduce framework height, take up space former insulator string effectively release, and save material investment.
To sum up, the present invention has the following advantages:
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 dual-layer metal line vertical arrangement, effectively have compressed interval width, saves floor occupying area.
3, because cross-arm have employed composite material, can utilize its electric property, cancel strain insulator and suspension insulator, then can reduce framework height, take up space former insulator string effectively release, and save material investment.
4, after adopting umbellate form compound cross-arm scheme, be connected more smooth and easy with circuit outlet.
5, framework facade is succinctly attractive in appearance, and processing and construction simply, save the building time of engineering.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Shown in Fig. 1-1, outlet structure comprises truss column 1, compound cross-arm beam 2, hanging wire ring 4, cat ladder 5 and other accessory kits, truss column 1 adopts single-column latticed steel structure, truss column 1 is provided with cat ladder 5, compound cross-arm beam 2 adopts Composite material, truss column 1 mediates, both sides arrange compound cross-arm beam 2, compound cross-arm beam 2 is combined by compound cross-arm and compound stay cable, 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 is fixedly connected with truss column 1, the other end is installed hanging wire ring 4 and is connected with truss column 1 tractive by compound stay cable, each compound cross-arm beam 2 and compound stay cable 3 and truss column Connecting groups synthesize two umbrella-shaped structure.
Described truss column 1 both sides arrange a compound cross-arm beam 2 and two compound cross-arm beams 2 respectively, and each compound cross-arm beam 2 connects a phase conductor, completes the outlet of A, B, C three-phase conducting wire.
As shown in Fig. 1-2 and Fig. 2-1, described truss column 1 the 3rd side increases by a compound cross-arm beam 2 and uses for wiring transition.
