Embodiment

[0025] see figure 1 , a connection structure and method for reducing the unbalanced tension of a tension tower. This embodiment is applied to the tension balance of a tension tower.

[0026] A connection structure for reducing the unbalanced tension of tension towers, including tension towers 1 and wires 2 connected between adjacent tension towers 1 or straight towers; see figure 1 , the crossarms on both sides of the tension pole tower 1 are provided with hanging wire pulleys 3, the wires 2 bypass the hanging wire pulleys 3, and the ends of the wires 2 are connected with hanging insulator strings 4 and counterweights 5, when the wires 2 are due to Icing or temperature drop causes the tension of the wire 2 to increase, and the counterweight 5 moves up under the action of the tension of the wire 2 to increase the length of the wire 2 in the gear, thereby reducing the tension of the wire 2 and reducing the stress on the tension pole tower 1. Unbalanced tension; when the ice and...

Abstract

The invention provides a connecting structure for reducing unbalanced tension of a strain tower. The connecting structure comprises a strain tower and a wire. A wire hanging pulley is arranged on the strain tower, the wire is wound around the wire hanging pulley, and the end portion of the wire is connected with a suspension insulator string and a balancing weight. The invention further provides a method for reducing the unbalanced tension of the strain tower. The method comprises the steps that the balancing weight is arranged according to the average operation tension of the wire; the wire is wound around the wire hanging pulley, and when the wire and the balancing weight reach a balanced state, a parallel groove clamp is installed, so that the distance between the initial installation position of the parallel groove clamp and the wire hanging pulley is larger than 0.5 m. The tension of the wire is dynamically adjusted through the cooperation of the wire, the wire hanging pulley and the balancing weight, the unbalanced tension borne by the strain tower is reduced, the bearing capacity of the strain tower to extreme weather conditions is improved, and tower falling accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of transmission line erection, in particular to a connection structure and method for reducing the unbalanced tension of a tension tower. Background technique [0002] When extreme freezing weather occurs, due to the large and small gaps and large height differences between towers in high mountains and ridges are very common, the uneven ice coating and uneven deicing on the wires are often more serious, making the towers vulnerable to greater damage. The unbalanced tension causes the tower to be bent and twisted, and even a tower collapse accident occurs. After a base tension tower falls, it will cause the towers on both sides to bear greater unbalanced force and impact force, expand the scope of the accident, and cause greater difficulties for repair and reconstruction. [0003] When the suspension type tower is subjected to unbalanced tension, part of the unbalanced tension can be released through the dis...
