Abstract
The utility model provides a tower head of an ultra-high voltage direct-current single-loop crossing tower. The tower head is in the shape that spreading wings are arranged on the two sides of the tower head. Each spreading wing is of a truss structure. Ground wire hanging points and wire hanging points are arranged on each spreading wing of the truss structure at intervals. The tower head is in the shape that the spreading wings are arranged on the two sides of the tower head, and therefore electrical clearance fit is compact, the wind shielding area is small, main columns of a tower body are low, the structure is simple, and compared with double-layer horn-shaped cross arms which are frequently used in existing crossing projects, the weight of the iron tower is reduced by about 6% due to the adoption of the spreading-wing-shaped cross arms.
Description
Technical field
The utility model relates to a kind of UHV transmission line steel tower tower head pattern, specifically a kind of extra-high voltage direct-current single loop crossover tower tower head.
Background technology
For extra-high voltage direct-current single loop crossover tower tower head, mainly adopt at present the goat's horn type tower head of wire cross-arm and earth wire support hierarchical design, tower body principal post and tower head center of gravity is higher, steel tower weight is larger when that this kind of tower head pattern profile coordinates with electric clearance is poor, tower head keeps out the wind area greatly and adopts this kind of tower head pattern.Therefore need to be optimized design to crossover tower tower head, make tower head coordinate compactness, the area that reduces to keep out the wind with electric clearance, reduce steel tower weight.
Utility model content
For goat's horn type tower head profile in prior art, coordinate poor, the tower head area that keeps out the wind larger with electric clearance, the problems such as steel tower weight is larger, the utility model provide a kind of coordinate with electric clearance compact, the area that keeps out the wind is little, tower body principal post is low, simple for structure, Path of Force Transfer transmission line of electricity crossover tower tower head clearly.
To achieve these goals, the technical solution adopted in the utility model is: a kind of extra-high voltage direct-current single loop crossover tower tower head, and described tower head comprises the both wings of stretching, extension, and both wings have certain angle, and described both wings are trussed construction.
On described each truss, interval arranges ground wire hanging point and conducting wire hanging point.
Described ground wire hanging point is positioned at the top of conducting wire hanging point.
Beneficial effect: tower head of the present utility model is the both sides shape of spreading the wings, make electric clearance coordinate compact, the area that keeps out the wind is little, tower body principal post is low, simple for structure, the use type cross-arm double-deck goat's horn type cross-arm conventional with overhead crossing engineering in the past of spreading the wings compared, steel tower weight reducing approximately 6%.Spread the wings that shape tower head is simple for structure, profile unfold attractive in appearance, tower head size is little, structural configuration is compact, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of extra-high voltage direct-current single loop crossover tower tower head, a kind of extra-high voltage direct-current single loop crossover tower tower head, described tower head comprises the both wings of stretching, extension, and both wings have certain angle, are the both sides shape of spreading the wings, and described both wings are trussed construction.Each truss 1 upper interval of spreading the wings arranges ground wire hanging point 2 and conducting wire hanging point 3.Ground wire hanging point 2 is positioned at the top of conducting wire hanging point 3.
Tower head adopts the type of spreading the wings to arrange, is to adopt public upper frame due to ground wire and wire, and ground wire and wire are arranged in spreads the wings on type tower head, and the crossover tower type tower head structural configuration compact and reasonable of spreading the wings, has effectively reduced the area that keeps out the wind, reduced tower body principal post height.
