Problems solved by technology

This kind of structural support frame has been used until now, but it also has the disadvantages of large area occupied by the roots and a large space corridor occupied by the upper part. With the rapid development of urban construction, the high-voltage line network will be greatly expanded, and the speed of urban relocation will be accelerated. The traditional high-voltage line support frame occupies a large area and is no longer suitable for its development, and the surrounding environment is poorly compatible, which affects the appearance of the city. At the same time, the large area occupied will also increase the cost of erecting high-voltage lines; It is more difficult to erect high-voltage lines in residential areas, river courses and narrow corridors

Embodiment Construction

[0018] Please also see image 3 , Figure 4 As shown, the ultra-high voltage transmission line support frame 20 of the present invention includes several main rods 21 , several cross arms 22 , connecting beams 23 , lightning conductor cross frames 24 , and support frame bases 30 . The support frame base 30 is deeply embedded in the ground (40 represents the ground), and the depth of embedding can reach 30-35m. On the piles 31 buried under the static pressure of concrete, for a support frame, the number of piles 31 buried under the static pressure of concrete varies from 30 to 60, and the base 30 can be made on site or can be a prefabricated part. The main rods 21 are fixed vertically on the support frame base 30 , usually the main rod 21 and the support frame base 30 are fixed by screw connection, and the length of the main rod 21 is about 52m. The lightning protection line cross frame 24 is installed horizontally at the top position of the main pole 21. Several cross arms 2...

Abstract

The invention discloses a super high-voltage transmission line support, including several main poles, several cross-arms, support base, connecting beam and lightning conductor horizontal rack. The support base is deeply buried underground, the main poles are fixed on the support base, the lightning conductor horizontal rack is arranged on the top of the main pole, the cross-arms are mounted under the lightning conductor horizontal rack and arranged on the upper part of the main pole, and the connecting beams are connected between main poles. The main pole is a hollow pole with small-calibered top end, large-calibered bottom end and oblong section. The invention has smaller bottom than the traditional supports, is suitable for narrow places.

Description

technical field [0001] The invention relates to high-voltage transmission and power supply lines, and more specifically refers to a support frame for ultra-high voltage transmission lines. Background technique [0002] In power transmission, the use of high-voltage transmission is the most common transmission method. In ultra-high voltage transmission, the voltage above 500kV is called ultra-high voltage. The high-voltage line support frame is used to erect the wires of the high-voltage line. For line spacing settings, see figure 1 , figure 2 As shown, this high-voltage line support frame 10 is usually composed of four main rods 11 to form a tower structure. The main rods 11 are all made of angle iron, and several cross arms 12 are connected between the main rods 11. In order to make the support frame firm, it is a tower The supporting frame of the structure uses a large root (the size of the root is large, generally up to about 12m), 14 is a lightning protection line hor...
