Problems solved by technology

[0006] However, the disadvantage of composite material poles is that the composite material has a small elastic modulus and large deformation, while the steel pipe has a large load-bearing capacity, and its application in poles is relatively mature. For this reason, it is necessary to provide a hybrid structure of composite materials and steel pipes poles, making full use of the respective advantages of composite materials and steel pipes to ensure efficient operation of transmission lines

Embodiment 1

[0049] A composite rod is composed of a column 1 and a panel 2 made of composite materials including carbon fiber and reinforced resin, and the surfaces of the column 1 and the panel 2 are respectively coated with a coating including a coloring agent and an anti-aging additive. The composite rod and the steel pipe 13 Connected into poles through flanges.

[0050] The column 1 is a D-shaped tube with a "D" shape in cross section. The thickness of the side wall 7 is 20 mm, and the thickness of the arc wall 8 is 7 mm. The angle between the two side walls 7 is 90°. The radius of the outer wall chamfer at the place is equal to 20mm, the radius of the inner wall chamfer is 8mm, the radius of the screw hole 9 is 12mm, the radius of the through hole 10 is 15mm, and the shrinkage angle β of the D-shaped tube is 0.38°. The panel 2 has a thickness of 28mm, a length of 400mm, and a width of 180mm.

[0051] Arrange the four columns 1 at the four corners of the composite rod with a square ...

Abstract

The invention provides a distribution circuit steel pipe and composite material mixing electric pole. The electric pole comprises a composite pole body and a steel pipe which are coaxially arranged. A flange is arranged between the composite pole body and the steel pipe. The improvement of the electric pole is characterized in that the composite pole body comprises vertical columns and batten plates; and the number of the vertical columns is larger than one, and the batten plates are horizontally arranged among the vertical columns at intervals and connected with the vertical columns through bolts. Compared with the prior art, according to the distribution circuit steel pipe and composite material mixing electric pole provided by the invention, the compressive strength and the strong-wind resistance of the electric pole are improved, moreover, the manufacturing cost, the transport cost, the installation cost and the maintenance cost are low, and meanwhile the width of a line corridor is decreased.

Description

technical field [0001] The invention relates to an electric pole, in particular to an electric pole mixed with steel pipes and composite materials for distribution lines. Background technique [0002] As early as 20 years ago, the U.S. Environmental Protection Agency had made strict restrictions on the chemical treatment of wooden poles. Composite poles have become an ideal substitute for traditional wooden poles in the United States. The major power transmission and distribution companies and various manufacturing companies in the United States are also actively researching and developing various composite material rods. Manufacturers such as EbertCompsites, Strongwell and Newmark have all developed their own composite pole products, which have been widely used in low-voltage distribution networks. And the composite material rod researched and developed by Canada's RS Company was selected by the "Future Circuit" project of Southern California Edison Company. This project i...
