Description
Technical Field
The utility model relates to a shaft tower technical field for the transmission line specifically is a transmission line combined material door type tower in narrow line corridor.
Background
The conventional transmission line pole tower corridor is large in width, for example, a 110kV single-circuit transmission line is used, the corridor width is 5.5-7.5 meters, the 220kV single-circuit transmission line corridor width is 10-15 meters, and the room crossing phenomenon inevitably occurs when the transmission line passes through a corridor limited area and a civil house dense area, so that the policy processing cost and the construction difficulty are greatly increased. Meanwhile, the conventional iron tower has a large root, and a standing place is difficult to find in the urban area where the earth is precious.

However, the use of composite materials for transmission towers also presents certain obstacles: 1) the connection problem is different from that of steel, the composite material is a brittle material, the opening of the holes can cause the breakage of the composite material fibers and also can cause great stress concentration, and the traditional connection mode cannot be suitable; 2) the cost and the processing cost of the component are high, the mold needs to be manufactured in advance for the processing and the molding of the composite material, each specification component needs to correspond to one set of mold, and if the specification of the component is too much and the component cannot be applied in a large scale, the processing cost of the component can be greatly increased, so that the price of the composite material component in China is always high at present; 3) the modulus of the glass fiber-based composite material is 30-60Gpa at one side and is far lower than that of the steel material by 200GPa, so that the deformation of the composite material tower with the same size is obviously larger than that of the steel pipe tower.
Therefore, how to fully exert the technical advantages of the composite material, through the reasonable structural design of the composite material tower, the technical advantages of light weight, high strength and insulation of the composite material tower are exerted, the defect of hole connection of the composite material is avoided, the convenience in production and processing and the convenience in installation are realized, and the high integral strength of the component becomes a key technical difficulty in the research of the composite material tower.
