Description
Technical field
The utility model relates to a kind of triangular section electric power pylon, belongs to power transmission and transformation equipment technology field.
Background technology
Steel tower is as the important device equipment of transmission line of electricity, and investment is large, difficult in maintenance.In extra high voltage network, shaft tower type selecting is based on quadrangle steel tower, Guywire tower and steel electric pole.A kind of Novel tower that triangular section electric power pylon is a kind of is section with triangle, make full use of " iron triangle " characteristic, than traditional quadrangle steel tower, have occupation of land less, the advantage such as simple structure, blast be few, it is convenient to construct, cost is low.
Summary of the invention
The purpose of this utility model is, for quadrangle steel tower Problems existing, proposes a kind of triangular section electric power pylon.
The technical solution of the utility model is, a kind of triangular section electric power pylon comprises the main material of tower mast, tiltedly material, tabula and horizontal material; Tower mast stands on three corners of ground equilateral triangle and oblique material, tabula and horizontal material by three main materials and to be formed by connecting three terrace with edge structures.Described main material cross section is round steel, round steel pipe, 60 ° of angle steel or W type combination angle steel.
Described W type combination angle steel is combined by welding by two 90 ° of angle steel; The end of a right-angle side of 90 ° of angle steel is welded to each other with the end of a right-angle side of 90 ° of angle steel and is connected, and the angle of another right-angle side of two 90 ° of angle steel is 60 °.
The beneficial effects of the utility model are, a kind of triangular section electric power pylon of the utility model, be a kind of be section with triangle, a kind of Novel tower of making full use of " iron triangle " stability characteristic (quality), simpler than traditional quadrangle iron tower structure, a few face, number of components can reduce about 25%, have occupation of land less, the advantage such as simple structure, blast be few, it is convenient to construct, cost is low.

Detailed description of the invention
Embodiment 1:
A kind of triangular section electric power pylon of the present embodiment comprises the main material of tower mast, tiltedly material, tabula and horizontal material; Tower mast stands on three corners of ground equilateral triangle and oblique material, tabula and horizontal material by three main materials and to be formed by connecting three terrace with edge structures.Main material adopts round steel pipe, as shown in Figure 1.
Embodiment 2:
A kind of triangular section electric power pylon of the present embodiment comprises the main material of tower mast, tiltedly material, tabula and horizontal material; Tower mast stands on three corners of ground equilateral triangle and oblique material, tabula and horizontal material by three main materials and to be formed by connecting three terrace with edge structures.Main material adopts 60 ° of angle steel, as shown in Figure 2.
Embodiment 3:
A kind of triangular section electric power pylon of the present embodiment comprises the main material of tower mast, tiltedly material, tabula and horizontal material; Tower mast stands on three corners of ground equilateral triangle and oblique material, tabula and horizontal material by three main materials and to be formed by connecting three terrace with edge structures.Main material adopts W type combination angle steel, as shown in Figure 3.
The W type combination angle steel of the present embodiment is combined by welding by two 90 ° of angle steel; The end of a right-angle side of 90 ° of angle steel is welded to each other with the end of a right-angle side of 90 ° of angle steel and is connected, and another right-angle side of two 90 ° of angle steel is mutually in 60 °.
Embodiment 4:
Supporting 220kV line project is become for certain city, design condition is wire 2xLGJ300/40, ground wire JLB20A/150, wind speed 27/s, icing 10mm is example, and the four limit tower basic mechanical design feature indexs that 220 kilovolts of SZ11S with SJ21S triangle towers and relative routine are suitable for are as table 1:
Table 1 basic mechanical design feature index table
Comparatively in quadrangle tower, triangle tower floor space reduces 56.7%, can save column foot land expropriation cost and have larger environmental protection and social benefit; Triangle tower compared to quadrangle tower, under the prerequisite that the same cross section type of main oblique material, material are identical, along with tower height increase, allow the increase of angle range, the increase of lead wire and earth wire external load, tower weight advantage is more and more obvious; Concerning common 220kV double, under same design service condition, triangle tower comparatively quadrangle tower tower weight can light about 5%-9%; To common 220kV double circuit line engineering, adopt triangle tower, its Foundation Design expense comparatively four limit towers can reduce about 4%-9%; To common 220kV double-circuit line engineering, the comprehensive cost 3%-5% lower than quadrangle tower of triangle tower, has certain economic benefit and larger social benefit (column foot expropriation of land scope reduces more than 50%).
