Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tension towers, in particular to a transition tension tower for a power transmission line. Background Art
[0002] With the rapid development of social economy, the number of power users and transmission lines is increasing. The land for transmission line corridors is becoming increasingly tight. It is very common for multiple transmission lines to share corridors with infrastructure such as highways and railways. When a new transmission line intersects with the above-mentioned corridor, the existing transmission line is often modified due to conflicts in demand such as crossing and drilling, which causes power outages for power users and increases construction investment. The role of the tension tower is like a wall, supporting this section of the line. Therefore, it is generally stronger than the straight tower. In the rain, snow and freezing disaster in 2008, the straight tower was seriously damaged. After multiple straight towers collapsed, the tension tower fell down because it could not withstand the strong tensile force. Most of the insulator strings of the current tension towers are installed in fixed positions, which is inconvenient to adjust and repair under different usage conditions. At the same time, the tower body is too high and is easily affected by bird nesting and collision, which in turn affects the subsequent use of the insulator string. For this reason, we propose a transmission line transition tension tower. Summary of the invention
