Concrete, the cross-arm of described tower head is long to be 58m.
Concrete, two ground wire hitch point distances of the ground line bracket of described tower head are 60m.
Concrete, the tower neck of described iron tower, body of the tower close the high 84.5m that is.
Preferably, described tower neck, body of the tower and tower leg adopt steel tubular structure.
Preferably, described tower head on crank arm and lower bent lever in be provided with damper.
Wineglass type extra-high voltage iron tower of the present utility model, when the iron tower size satisfied the electric clearance of UHV transmission, because the tower head of iron tower adopts steel tubular structure, so the tower head member was few, designs simplification, be convenient to processing; The tower head windage of use steel tubular structure and wind shake, and non-deformability little, whole tower head strengthens; Further, tower neck, body of the tower and tower leg all adopt steel tubular structure, make iron tower integral body more stable; In addition, full tower adopts steel tubular structure, can also significantly reduce the steel consumption.
Description of drawings
Fig. 1 is the structural representation of the utility model extra-high voltage with iron tower embodiment.
The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model embodiment is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model provides the embodiment of a kind of extra-high voltage with iron tower, and as shown in Figure 1, described iron tower 1 is a wineglass sections tower, comprising: tower head 11, tower neck 12, body of the tower 13 and tower leg 14.The tower head 11 of described iron tower 1 adopts steel tubular structure.
Compare with the tower head of angle steel structure, wineglass type tower head the number of components of steel tubular structure is few, designs simplification, be convenient to processing; It is little that the build coefficient of tower head is little, windage and wind shake, and big, the counter-bending performance of rocking of the rigidity of section of steel pipe is good in addition, makes the non-deformability of whole tower head strengthen.Compare with the angle iron component of equal section area, the element bearing capacity and the stability of steel tubular structure are much higher, single steel pipe can satisfy bearing capacity and stability design requirement, adopt the angle steel structure then to need two or four angle iron components to make up and fix with screw, screw, thereby the number of components that the tower head of steel tubular structure needs is few, designs simplification, be convenient to processing, and reduced the use amount of steel; In addition, shapefactorofwindload obtains according to the load modular formula, the area that keeps out the wind of wind load and build coefficient and member is linear, tower head for steel tubular structure, its shapefactorofwindload is about 0.7 times of angle steel structure, thereby adopts the suffered wind load of the tower head of steel tubular structure much smaller.
Described body of the tower 13 is erected on the tower leg 14, and the horizontal section of described body of the tower 13 is rectangular.Preferably, described body of the tower 13 is positive truncated rectangular pyramids.
Described tower neck 12 is erected at body of the tower 13 tops, is postponing that body of the tower 13 makes progress.
Described tower head 11 is erected on the tower neck 12, comprise crank arm 111, cross-arm 112 and ground line bracket 113.Described cranking arm 111 is connected with tower neck 12, and directly frame is on tower neck 12; Described iron tower comprises that two are cranked arm 111, and each is cranked arm and comprises and crank arm 1111 and lower bent lever 1112.
Described cross-arm 112 symmetries ride over cranks arm on 111.Be mounted with I type insulator string (not shown) on the middle cross-arm 1122 of cross-arm 112, described insulator string lower end articulates phase conductor (not shown) in the extra-high voltage; Two limit cross-arms 1121 of cross-arm 112 near the position at cross-arm 112 two ends respectively symmetry be mounted with I type insulator string (not shown), I type insulator string lower end articulates extra-high-speed flanging phase conductor (not shown).Phase conductor and limit phase conductor adopt horizontally in of the present utility model, have therefore reduced the height of lead hanging point, thereby reduce the height of whole tower.
Preferably, described tower neck 12, body of the tower 13 and tower leg 14 all adopt steel tubular structure.Because the rigidity of steel tubular structure is better, be out of shape forr a short time, so tower neck 12, body of the tower 13 and tower leg 14 employing steel tubular structures more help the monolithic stability of long span transmission line structure; In addition, also be beneficial to the windage that reduces iron tower 1 integral body.
Described ground line bracket 113 is overhanging formula, and 113 of ground line brackets are on the limit of cross-arm 112 cross-arm 1121, and ground line bracket 113 hangs anti-lightning strike ground wire (not shown) at the end away from limit cross-arm 1121.
Preferably, for the electric clearance requirement of phase conductor in satisfying to iron tower 1 cross-arm 112, the middle cross-arm 1122 of described iron tower 1 is arch, with the space of abundant reasonable use iron tower 1 tower head 11 parts.
Main stressed member on the tower head 11 cranks arm 1111 and the main material of lower bent lever 1112 on being, and is preferred, crank arm on the tower head 11 1111 and lower bent lever 1112 in be provided with damper.Because tower head 11 all adopts steel tubular structures, therefore, on crank arm 1111 and lower bent lever 1112 in be hollow, can be by damper (as the plumbous heart damper of rubber), reduction wind-induced vibration effect be set in the tube wall of tower head 11 main stressed members.
Iron tower 1 of the present utility model is applicable to 500kV and above transmission line of electricity, has relocatable scope according to each sizes of the different iron towers of electric pressure and wire type.For the 1000kV transmission line of electricity, exhaling of described iron tower 1 claims that high H is 168m; The high M of tower head is 52.3m; The long L of the cross-arm of tower head 11 is 58m; Two ground wire hitch point distance W of the ground line bracket 113 of tower head 11 are 60m, form negative shielding angle thus, are beneficial to the safety of protection iron tower 1; It is 84.5m that the tower neck 12 of iron tower 1, body of the tower 13 close high D, and the high E of tower leg is 45m, and between adjacent tower leg is 39.06m apart from K.
Wineglass type extra-high voltage iron tower of the present utility model, when the iron tower size satisfied the electric clearance of UHV transmission, because the tower head of iron tower adopts steel tubular structure, so the tower head member was few, designs simplification, be convenient to processing, has reduced the use amount of steel; Use the tower head shapefactorofwindload of steel tubular structure little, windage and the wind non-deformability little, whole tower head of shaking strengthens; Further, tower neck, body of the tower and tower leg all adopt steel tubular structure, make iron tower integral body more stable; In addition, full tower adopts steel tubular structure, can also significantly reduce the steel consumption.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.All any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all be included in the protection domain of the present utility model.
