A torque base transmission line wind-proof iron tower

Abstract

A torque base transmission line wind-proof iron tower is designed to solve the problem of wind-proof iron towers in existing transmission towers. The torque base transmission line wind-proof iron tower of the present invention comprises a torque tower base, tower legs, tower body, tower head, conductors and insulators. The torque base transmission line wind-proof iron tower of the present invention is provided with a torque tower base. When wind-proof iron tower occurs, the transmission line swings, causing the torque tower base and the tower body to rotate relative to each other. The resistance connecting member can offset the torque of the relative rotation, further stopping the swing and restoring the tower body to its initial position under the restoring force of the resistance connecting member. The relative rotation of the torque tower base and the tower body reduces the tension on the transmission line caused by wind-proof iron tower, avoids the simultaneous resonance of the tower and the transmission line when wind-proof iron tower occurs, effectively reduces the wind-proof energy, and further ensures the safety of power supply.

Description

Technical Field

[0001] The invention relates to a windproof iron tower. Background Art

[0002] Windage on transmission lines refers to the phenomenon in which conductors deviate due to wind, resulting in insufficient insulation distance between the transmission line and the tower, leading to flashover discharge. Windage discharge on transmission lines has always been a major issue affecting the safe operation of transmission lines, especially on trunk transmission lines. Because trunk transmission lines are difficult to reclose successfully after flashover, a windage flashover on a trunk transmission line can cause widespread power outages, seriously impacting the reliability of the power system.

[0003] Wind-induced flashovers on transmission lines exhibit the following patterns and characteristics: wind-induced flashovers often occur under adverse weather conditions, reclosing is rarely successful when wind-induced flashovers occur, and the location of wind-induced flashovers is uncertain. Therefore, wind-induced flashovers on transmission lines are characterized by widespread impact, high frequency, and significant impact. In recent years, researchers have proposed a series of wind-induced flashover mitigation measures to address wind-induced flashover incidents in power grids, such as replacing single-strand insulator strings with double-strand V-shaped insulator strings, attaching weights beneath insulator strings, and even replacing straight-line towers with tension-type towers. Technically, these measures can mitigate the harm caused by wind-induced flashovers to a certain extent. However, in terms of operational ease and economic feasibility, solutions such as replacing single-strand insulator strings with V-strings and replacing straight-line towers with tension-type towers are difficult and expensive to construct, and require power outages during operation. The use of weighted hammers to mitigate wind-induced flashover incidents can only partially mitigate wind-induced flashover incidents. Due to the large surface area of ​​the weighted hammers, they are easily swept by wind. Many hammers weigh hundreds of kilograms, adding additional weight to the tower and increasing the design margin. Strong winds can easily damage towers, leading to tower collapse and line breakage in severe cases, resulting in more serious consequences than wind deflection and tripping. Transmission towers primarily include angle steel towers, steel tubular towers, steel tube and angle steel composite towers, and steel tubular poles. Transmission towers include wine glass, cathead, up-shaped, dry-shaped, and barrel-shaped types. However, these towers are mostly rigid and have a fixed vibration frequency, providing only support. When wind deflects a transmission line, they are prone to simultaneous resonance with the transmission line, failing to effectively mitigate wind deflection energy. Summary of the Invention
