Description
Technical field
The utility model is related to a kind of single loop tangent tower, especially with regard to one kind high altitude localities (height above sea level 4000~
5000m), the especially big use span 500kV single loop wine glass-shapeds in high altitude localities that span is applied in the case of being 1600m~1800m
Tangent tower.
Background technology
The 500kV electric power line pole towers of high altitude localities design, need to pay close attention to conducting wire electric clearance adjustment and especially big span,
The geographic and geomorphic conditions of especially big height difference, therefore, it is necessary to for the special weather orographic condition of high altitude localities, design is a kind of high
The especially big span tangent tower of Altitude Regions 500kV single loop wine glass-shapeds.
Currently, the especially big span tangent tower of national line single loop uses cat-head transmission tower layout pattern, conducting wire to be arranged using triangle
Row.This steel tower tower head height is larger, and lightning protection properties are poor, and stress is relative complex, steel tower heavier-weight, and project cost is higher.
Simultaneously as High aititude mountain area tower position landform is poor, climatic environment is severe, tower erection constructional difficulties, cathead tower head height
Larger, risk is found in the lifting and group for increasing tower head pole stock.
Invention content
In view of the above-mentioned problems, the purpose of this utility model is to provide, a kind of high altitude localities is especially big to use span 500kV mono-
Circuit wine glass-shaped tangent tower can reduce tower head height, reduce steel tower weight, reduce steel tower comprehensive cost, improving operation can
By property, while also reducing lifting and the construction risk of steel tower tower head pole stock.
To achieve the above object, the utility model takes following technical scheme：A kind of high altitude localities is especially big to use span
500kV single loop wine glass-shaped tangent towers, it is characterised in that：It includes tower head and tower body, and the tower head is arranged on the tower body top
Portion；The tower head includes cross-arm and tower head interconnecting piece, and the tower head interconnecting piece uses two, and the two tower head interconnecting piece settings
In the cross-arm lower part and it is arranged in parallel；V-structure is used at the top of the tower body, is connect with the two tower head interconnecting pieces.
Further, the three-phase conducting wire of the tower head is using the horizontally arranged wine glass-shaped arrangements of IVI.
The utility model has the following advantages due to taking above technical scheme：1, the utility model can meet high sea
It rises sheer from level ground area's electric clearance requirement, and more conventional cathead tower head arrangement can effectively reduce tower head height, improves lightning protection properties, drop
Low tower weight reduces steel tower comprehensive cost.2, since High aititude mountain area tower position landform is poor, climatic environment is severe, and tower erection is applied
Work is difficult.The utility model tower head height reduces, and reduces lifting and the construction risk of steel tower tower head pole stock.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the tower head structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of high altitude localities of the utility model offer is especially big uses span 500kV single loop wineglasses
Type tangent tower comprising tower head 1 and tower body 2, the setting of tower head 1 is at 2 top of tower body.Tower head 1 includes cross-arm 11 and tower head interconnecting piece
12, tower head interconnecting piece 12 uses two, and two tower head interconnecting pieces 12 are arranged in 11 lower part of cross-arm and are arranged in parallel.2 top of tower body
Using V-structure, it is connect with two tower head interconnecting pieces 12.
In above-described embodiment, the three-phase conducting wire of tower head 1 is using the horizontally arranged wine glass-shaped arrangements of IVI.
In the various embodiments described above, the size of tower head 1 can be according to high altitude localities (height above sea level 4000m~5000m) electric equipment compartment
Gap is adjusted.
In the various embodiments described above, the tangent tower being made of tower head 1 and tower body 2 need to meet the especially big span in high altitude localities
The requirement of (1600m~1800m) design condition.
In conclusion when the utility model is used, the used more conventional cathead tangent tower of wine glass-shaped tangent tower by
Power is more reasonable clear, security reliability higher.The tower conducting wire of the utility model is using horizontally arranged, compared with the cat of triangle arrangement
The tower head height of head tower is lower, substantially reduces steel tower weight and the risk of lightning stroke rate.The tower tower head of the utility model designs
The design of routine 500kV circuit tower head sizes is broken through, three-phase conducting wire is horizontally disposed using IVI, and phase spacing meets under windage yaw effect
Adjacent two phase conductor is not less than alternate minimum operation overvoltage gap under the especially big span situations of 1600m~1800m close to distance
Requirement (electric clearance by height above sea level 4000m~5000m correct), and there are adequate allowances.The tower of the utility model is suitable for
High altitude localities and extreme Disadvantageous combination situation there are especially big span, high safety and reliability, low cost, construction operation and maintenance side
Just, there is preferable economic and social benefit.
The various embodiments described above are merely to illustrate the utility model, and structure and size, installation position and the shape of each component are all
Can be varied from, on the basis of technical solutions of the utility model, it is all according to the utility model principle to individual part into
Capable improvement and equivalents, should not exclude except the scope of protection of the utility model.
