High-voltage power transmission tower with cable pendency adjusting function

Abstract

The invention relates to the technical field of power transmission towers, in particular to a high-voltage power transmission tower with a cable pendency adjusting function. The high-voltage power transmission tower comprises a base tower and movable cross arms; the movable cross arms are arranged on the left side and the right side of the base tower correspondingly, and comprise bracket plates, connection plates, fixing pulling rods, connection rods and insulation ceramic parts; grooves are formed in the upper ends and the lower ends of the two sets of bracket plates correspondingly, and theconnection plates, the fixing pulling rods and the connection rods are fixedly connected between the two sets of bracket plates; the insulation ceramic parts are arranged at the tail ends of the bracket plates, and top plates and bottom plates are arranged at the upper ends and the lower ends of the movable cross arms correspondingly, and fixed into the base tower; and idler wheels are evenly arranged on the front sides and the rear sides of the bottoms of the top plates as well as the front sides and the rear sides of the tops of the bottom plates correspondingly. The high-voltage power transmission tower is novel in design, the cable pendency can be adjusted, the windward area of the upper end of the power tower under strong wind weather can further be decreased, the risks of breaking and collapsing of the power transmission tower are lowered, and the high-voltage power transmission tower is suitable for being further applied and popularized.

Description

technical field [0001] The invention relates to the technical field of power transmission towers, in particular to a high-voltage power transmission tower with the function of adjusting the degree of suspension of cables. Background technique [0002] Electric towers are trapezoidal or triangular tower-shaped buildings, usually 25-40 meters high, and are steel frame structures. High-voltage electric towers are an important way of power transmission in my country. A large number of high-voltage electric towers are used in the West-to-East Power Transmission Project. With the development of the economy, the stable development of the national electric power industry has a direct relationship with the economic development of our country. . [0003] The transmission tower mainly plays the role of fixing and supporting the cables, and the sagging degree of the cables during the cable fixing process is one of the more important control indicators. During use, the cable is prone to...

AI Technical Summary

Problems solved by technology

When the sag of the cable is large, the cable will sway greatly under the influence of wind force. Under the action of the cable dancing inertia, the force on the transmission tower will increase sharply, which will cause the transmission tower to break and collapse. Now The power transmission tower in the state of the art cannot adjust the suspension degree of the cable
