Compound material pole tower

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...

Problems solved by technology

The main problems faced in the construction and operation of my country's transmission lines are different from those of foreign countries. my country's transmission lines are widely distributed and often face the influence of various complex geographical environments and climate environments. With the rapid growth of transmission line construction, line failures occur The number of times is increasing year by year; at the same time, due to the land occupation of the corridor, the cost of land acquisition and house demolition during the construction of the line is also increasing year by year
