Embodiment

[0021] Example: Select the type of overhead transmission poles and towers that are vulnerable to typhoons in coastal areas such as figure 1 The overhead power transmission tower is shown as an example, and the horizontal diaphragm of the overhead power transmission tower includes four corner column main materials 8 .

[0022] The overhead transmission tower is analyzed through the structural analysis of the prior art and the method of on-site measurement, and the weak parts of the overhead transmission tower are found out.

[0023] By analysis, such as figure 2 The cross section in the middle of the tower shown is prone to premature local vibration and bar instability, which is the main weak point. Therefore, it is chosen to install the velocity vibration-damping support base and the tuning mass vibration-damping damper on such as figure 2 location shown.

Abstract

The invention provides an overhead electricity transmission line tower with high wind resistance, wherein a horizontal separation face of the line tower comprises four corner post main materials (8), wherein the four corner post main materials are equipped with four horizontal frame additional rod parts (6) which are connected into a frame shape, and the four corner post main materials are also equipped with two main supporting rods (3) which are respectively crossed and supported on the corner post main materials on opposite angles; a center round ring (4) is firmly supported on the main supporting rods in the frame shape, an incircle ring (5) is also disposed in the frame shape, contact points of the incircle ring are firmly connected with the horizontal frame additional rod parts, and the center point of the incircle ring is firmly connected to the main supporting rods; and four speed vibration-reduction damping devices (7) are disposed symmetrically between the center round ring and the incircle ring, and the included angle between a connection line of the speed vibration-reduction damping devices in opposite directions and the direction of an electricity transmission wire is less than 60 DEG. The overhead electricity transmission line tower with the high wind resistance provided by the invention integrates speed vibration reduction, tunes mass vibration reduction and increases performances of the overhead electricity transmission line tower so as to reduce risks of damages and destroy of the overhead electricity transmission line tower, is highly targeted, obtains significant effect, is constructed easily, and can be widely applied in the technical field of wind resistance of overhead electricity transmission line towers.

Description

technical field [0001] The invention relates to an overhead power transmission tower, in particular to an overhead power transmission tower with high wind resistance performance. Background technique [0002] Overhead power transmission towers are an important part of the power transmission process. The damage and collapse of overhead power transmission towers will lead to interruption of power transmission, paralysis of all related industries and possible secondary disasters such as fires, resulting in serious losses. As a towering structure, overhead transmission towers, coupled with large spans of conductors and ground wires, are structures with obvious wind-induced response. Under the action of strong winds, damage to overhead transmission towers often occurs. [0003] In the Technical Regulations on the Design of Tower Structures for Overhead Transmission Lines (DLT5154-2002), the cross section of overhead transmission towers generally includes four main corner columns....
