Problems solved by technology

[0002] With the development of the power grid, there has been a national network, west-east power transmission, and north-south mutual power supply network construction pattern. There are more and more transmission line projects, and the demand for steel is also increasing. At present, the transmission line towers adopt all-steel structures. There are problems such as heavy weight, difficulty in construction, transportation, and operation and maintenance. At the same time, there are also shortcomings and deficiencies such as large size of transmission tower head, wide corridor width, heavy tower, cumbersome processing and high cost.

Embodiment 1

[0018] See Figure 1-4 , the tower head 18 and the upper body section 4 of the left and right components adopt composite materials, and the lower section 1 of the tower body is a steel pipe rod; The upper end flange 16-2 is connected; the lower part of the tower body 1 is connected to the steel ladder 2; the upper part of the tower body 4 of the composite material is connected to the composite material ladder 5, and the metal ladder 2 and the composite material ladder 5 are connected up and down and assembled at the joint Double ladder clamping plate 3; The tower head 18 of composite material connects composite material climbing ladder single ladder 12, and composite material climbing ladder single ladder 12 lower end connects the composite material climbing ladder 5 of tower body section; See figure 1 , 6 , two sets of support rods 6 are cross-connected between the tower body sections 4 of the left and right components, and the two clamping hoops 13 are connected by bolt...

Embodiment 2

[0021] See figure 1 , 4 , The tower head 18, the tower body section 4, the tower body lower section 1 and the ladder 2 connected to the tower body lower section 1 are all made of composite materials; other structures are the same as in Example 1. The lightning conductor is grounded from the outside of the shaft, which is convenient for normal and safe inspection of the lightning conductor.

Abstract

An electric transmission line tower made of composite materials is provided with a left assembly and a right assembly. The left assembly and the right assembly both comprise tower heads, cross arms, tower body upper sections and tower body lower sections. The electric transmission line tower is characterized in that the tower heads and the tower body upper sections are made of composite materials, the tower body lower sections are made of steel pipe poles or composite materials, the steel pipe poles of the tower body lower sections are connected with metal ladders or ladders made of composite materials, the tower body upper sections are connected with the ladders made of composite materials, the tower heads are connected with a single ladder made of composite materials, the left cross arms and the right cross arms are formed by parallel double poles, and two ends of the left cross arms and the right cross arms are connected with the top ends of the tower heads through double inclined draw bars. The tower made of composite materials is simple in structure, easy to assemble, long in service life and capable of resisting corrosion and aging and oxidation, eliminates suspension insulator strings on the existing towers, reduces electrical distance, reduces electrical distribution size, narrows line channels, is light in weight and free of maintenance, reduces line cost and saves operation cost.

Description

technical field [0001] The invention relates to an overhead power transmission line tower, in particular to a composite material transmission line tower, which uses composite materials instead of steel, and is suitable for line crowded areas, urban and suburban development areas, other special lines and special areas. Background technique [0002] With the development of the power grid, there has been a national network, west-east power transmission, and north-south mutual power supply network construction pattern. There are more and more transmission line projects, and the demand for steel is also increasing. At present, the transmission line towers adopt all-steel structures. There are problems such as heavy weight, difficulty in construction, transportation, and operation and maintenance. At the same time, there are also shortcomings and deficiencies such as large size of transmission tower head, wide corridor width, heavy tower, cumbersome processing and high cost. [00...
