Description
Technical field
The present invention relates to ultra-high-tension power transmission line technical field, especially a kind of three loop landscape tower of new mixed pressure.
Background technology
Three back transmission line of existing routine adopts upper one time, the arrangement of lower twice at present, for 500kV/220kV
Mixed pressure circuit, is affected by aspects such as conducting wire sag, electric clearances, and the spacing of different electric pressure circuits is larger, increases shaft tower
Tower head size.As 500kV is located at tower body top, shaft tower lines load moment of flexure effect substantially, exacerbates shaft tower stress, increases
Shaft tower tower material is consumed.500kV is arranged vertically with 220kV, and when 500kV is overhauled, 220kV circuits need to be accompanied and be stopped, and increases operation inspection
The difficulty repaiied.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of three loop landscape tower of new mixed pressure, the new mixed pressure
Three loop landscape towers propose the tower head scheme of " 500kV/220kV or so mixed pressures arrangement ", with " the upper and lower mixed pressures of 500kV/220kV " side
Case is compared, and is effectively reduced lines load moment of flexure effect, is reduced tower head size, is reduced shaft tower and is exhaled high, realizes 500kV and 220kV
Circuit split window horizontal alignment runs, and effectively lifts circuit operating maintenance convenience degree.
The present invention solves the technical scheme that adopted of above-mentioned technical problem：
A kind of three loop landscape tower of new mixed pressure, including tower body, cross-arm and suspension string, the cross-arm include landscape cross-arm, middle level
Wire cross-arm and lower layer conductor cross-arm, the landscape cross-arm are placed in the top of tower body, arrange both sides cross-arm perpendicular to line direction,
Middle layer conductor cross-arm is placed under landscape cross-arm, arranges both sides cross-arm perpendicular to line direction, and lower layer conductor cross-arm is placed in middle level
Under wire cross-arm, both sides cross-arm is arranged perpendicular to line direction, it is horizontal that the suspension string is respectively placed in landscape cross-arm, middle layer conductor
On the both sides cross-arm of load and lower layer conductor cross-arm, and landscape cross-arm adopts three-layer type head of the horse structure.
The suspension string includes 500KV suspension strings, 220KV suspension strings and ground wire suspension string, and landscape cross-arm lower floor side is slightly
Portion hangs a 500kV suspension string, and lower floor's opposite side ending and middle part hang two 220kV suspension strings, and landscape cross-arm middle level is slightly
Portion fixes the side ending of ground wire suspension string suspension ground wire, the middle layer conductor cross-arm and lower layer conductor cross-arm and hangs one
The opposite side ending of 500kV suspension strings, the middle layer conductor cross-arm and lower layer conductor cross-arm and middle part hang two 220kV pendencys
String.
The suspension string is designed using V-type string, and cross-arm size is affected by 500kV, 220kV wire pitch, effectively can be reduced
Wire pitch is limited, and reduces cross-arm width.
Beneficial effects of the present invention：The tower head scheme of the new proposition " 500kV/220kV or so mixed pressures arrangement ", with
" the upper and lower mixed pressures of 500kV/220kV " scheme is compared, and is effectively reduced lines load moment of flexure effect, is reduced tower head size, reduces shaft tower
Exhale high, realize that 500kV is run with 220kV circuit split windows horizontal alignment, effectively lift circuit operating maintenance convenience degree.
Description of the drawings
Further illustrate with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Three loop landscape tower of a kind of new mixed pressure as shown in Figure 1, by tower body 1, landscape cross-arm 2, middle layer conductor cross-arm 3,
Lower layer conductor cross-arm 4,500kV suspension strings 5,220kV suspension strings 6 and ground wire suspension string 7 are constituted.
Landscape cross-arm 2 is set at the top of tower body 1, and landscape cross-arm 2 is set using three-layer type seal wall with reference to Hui Style Architecture style
