500kV transmission single-circuit linear tower

Abstract

The invention provides a 500kV transmission single-circuit linear tower, belongs to the field of transmission lines, and aims to improve the rationality of structure power transmission and the economical efficiency. The 500kV transmission single-circuit linear tower comprises a tower body, a cross beam and ground line brackets, wherein two curved arms are mounted on the tower body, the cross beamis connected onto the two curved arms, and the two ground line brackets are supported on the cross beam; the curved arms comprise an upper curved arm and a lower curved arm, an end face of the upper curved arm is a triangle which gradually increases from top to bottom, the top end of the upper curved arm extends to the bottom surface of the cross beam, and is provided with a gusset plate I, and the top end of the upper curved arm and the beam are both connected to the gusset plate I. According to the 500kV transmission single-circuit linear tower, the corridor span is about 1 m smaller than that of a conventional cup type tower, reducing the tower height of house demolition and sideline control towers; the weight of the tower is about 4% lighter than that of the conventional cup type tower, and the economic benefit is remarkable; and nodes in a similar K shape are avoided, the construction safety is good, and the deformation is small.

Description

technical field [0001] The invention belongs to the field of power transmission lines, in particular to a 500kV power transmission single-circuit linear tower. Background technique [0002] With the development of the economy, the demand for electricity is increasing, which drives the rapid development of power grid construction. The power grid mostly uses overhead lines, so the demand for iron towers has increased significantly. Single-circuit linear towers generally need to support the load of two ground wires and three-phase wires. . At present, the single-circuit straight towers of domestic transmission lines mostly adopt cat head towers, wine glass towers, upper-shaped towers, and lower-shaped towers. The above tower types have the following disadvantages: [0003] 1. The cat head tower, the wires of the cat head tower are generally arranged in a triangle, and the corridor width is small, but because the tower head is high, the wind load of the ground wire and the uppe...
