Embodiment

[0025] Example: such as figure 2 Medium composite material towers, taking 110kV line towers as an example, are designed according to the linear tower with a line span of 300m, and the main parameters of the tower can take the following values: D 1 =D 2 = 3.0m, D 3 = 3.0m, r A = 1.2m, r B = r C = 1.5m, the creepage distance of the insulating cross-arm is 3650mm. First of all, the clearance distance of each pole tower meets the design requirements of 110kV line (the minimum phase-to-ground clearance distance is greater than 1.0m, the insulation creepage distance is not less than 3650mm in Class III polluted areas, and the horizontal insulation distance between phases is D 1 satisfy ≥ 0.4 L k + U / 110 + 0.65 f c , Vertical insulation distance between phases D 2 satisfy ...

Abstract

The invention relates to a compound material pole tower. A main body of the pole tower adopts a compound material; a main connecting part adopts compound material or galvanized steel; a lead cross armadopts a compound insulator; a ground lead cross arm adopts galvanized steel; a downlead cross arm adopts galvanized steel adopts galvanized steel; a grounding downlead adopts wires and bars; the upper end of the grounding downlead is fixed on the grounding wire cross arm, is led from leads at the outside of one side or two sides of the pole tower, is fixed on the downlead cross arm to lead the grounding downlead and the lead to keep fixed distance, and is grounded from the downlead cross arm along the tower body. Compared with the conventional 110kV iron tower, the compound material pole tower greatly increases phase-earth and interphase air gaps and insulating creepage distance of a tower head, greatly improves pollution flashover resistance, ice flashover resistance, windage yaw prevention and lightning-resistant level, also can compress the size of the tower head, and has the advantages of reducing the cost as well as expenses for transportation, installation and maintenance of the pole tower body and simultaneously reducing the width of a line corridor.

Description

technical field [0001] The invention belongs to the field of power transmission lines, and in particular relates to a composite material pole tower. Background technique [0002] Towers are important equipment for transmission lines. At present, transmission lines with a voltage level of 110kV and above in my country mostly use iron towers. The disadvantages are that they are easy to corrode, heavy in weight, easy to be stolen, and prone to wind deflection, pollution flashover, and ice in harsh natural environments. Lightning strikes, lightning strikes, etc., cause line trips or even outage accidents. [0003] Composite materials have the characteristics of light weight, high strength, good insulation, anti-climate aging, and strong corrosion resistance. Applying composite materials to transmission line towers can greatly improve the insulation of the line, and greatly improve the line's resistance to pollution flashover and ice flashover. , wind resistance, lightning resist...
