Lattice insulation power transmission tower

Abstract

The invention discloses a lattice insulation power transmission tower which comprises a plurality of standard sections which are mutually connected. Each standard section comprises four composite tubular principal materials, a composite digging cable body system and a composite horizontal rod body system. An intermediate node steel sleeve is installed on the middle portion of each composite tubular principal material, an end node steel sleeve is installed on the end portion of the composite tubular principal material, and a flange is arranged on the end node steel sleeve. The composite digging cable body system comprises a composite digging cable and a composite digging cable end portion U-shaped ring connection piece. The U-shaped ring connection piece comprises an annular cylinder connected with the composite digging cable and a U-shaped portion located at the front end of the annular cylinder. The composite horizontal rod body system comprises a composite horizontal rod and a composite horizontal rod U-shaped inserting plate connection piece. The lattice insulation power transmission tower adopts a lattice mode, increases stiffness of a composite tower, improves shortcomings of material stiffness, achieves a purpose of improving rigidity and bearing capacity of a tower structure, and brings convenience to application and dissemination in high voltage and ultrahigh voltage electric transmission line projects.

Description

technical field [0001] The invention belongs to the field of electric equipment, and relates to a power transmission tower structure, in particular to a lattice-type insulated power transmission tower. Background technique [0002] At present, the structure of transmission towers mainly adopts all-steel structure, which consumes a lot of steel and mineral energy, causing serious pollution to the ecological environment. In addition, the line tower adopts an all-steel structure, which has problems such as heavy weight, difficulty in construction, transportation, and operation and maintenance. At the same time, due to the advantages of low carbon, energy saving, environmental protection, high strength, light weight, corrosion resistance, easy processing, strong designability and good insulation performance, composite materials have become one of the ideal materials to replace steel in building transmission tower structures. [0003] In order to promote the use of composite mat...

AI Technical Summary

Problems solved by technology

Single-rod composite material poles have mature products in the domestic market, but their rigidity is small and their bearing capacity is low, which makes it difficult to meet the heavy load requirements of high-voltage line engineering, which greatly limits the application of composite materials in transmission line engineering ; Lattice insulating transmission towers have the potential to be popularized and applied in high-voltage transmission line projects due to their high rigidity and high bearing capacity.

However, due to the difficulty of research, there are no related products in the domestic and foreign markets
