1, The function of traction plate and adjustment plate
In the construction of high-voltage transmission towers, traction plates and adjustment plates are two important components that can adjust wire tension and maintain line safety.
Traction plates are divided into two types: horizontal and vertical. They are usually installed at the cantilever end, corner, and overhead line corner of the tower. During the transmission process, the wires are wrapped around the traction plate to form bends. By bending, the tension of the wires can be adjusted and the suspension of the lines can be eliminated. Therefore, the main function of the traction plate is to relieve the tension of the wire insulator and effectively protect the line insulator.
The adjustment board is designed to address the issue of wire tension, and it can adjust and limit the tension of the wire. Meanwhile, adjusting the board can also maintain the vertical and horizontal straightness of the circuit.
2, The difference between traction board and adjustment board
Although the functions of the traction plate and the adjustment plate are similar, there are still some differences in their application.
Firstly, the installation location. The traction plate is mainly installed at the center point of the span, while the adjustment plate is installed at the end position of the span.
Next is the scope of action. The traction board mainly functions at the bending point of wire winding, while the adjustment board functions as a whole for the circuit.
Finally, the principle of action. The working principle of the traction plate is mainly to form a "traction bow" by bending wires per unit length, forming a diagonal support effect; The adjustment board adjusts the tension and position of the wires by the number and angle of bends.
3, The importance of traction plates and adjustment plates
The traction plate and adjustment plate can be said to be a very important part of power transmission. During the transmission process, changes in wire tension and position can pose a significant threat to transmission safety. Therefore, the selection of traction plates and adjustment plates can not only ensure the integrity of the circuit, but also extend the service life of the wires, thereby maintaining the stability and reliability of power transmission. At the same time, when installing the traction board and adjustment board, safety factors should also be considered and the safety of the circuit should not be affected.
In short, traction plates and adjustment plates are essential components for power transmission. They can not only adjust the tension and position of wires, but also ensure the safety and stability of the line to a large extent. In power transmission, we need to select suitable traction plates and adjustment plates according to specific line requirements to ensure the reliability and safety of the line.
