Problems solved by technology

[0004] However, there are still relatively obvious defects in its use: 1. The above-mentioned device uses a plurality of fixing parts to fix the transmission line, but when the wind speed in the external environment is relatively large, the wind force directly acts on the fixing parts, still It will cause damage to the fixing parts, because the above-mentioned device cannot guide and consume the wind force in time, and there are hidden dangers; 2. The above-mentioned device is a completely fixed limit for the transmission line, so that the wind force will directly act on the surface of the transmission line. At this time, Since the surface of the power transmission line is continuously subjected to a large force, local damage may occur. In order to avoid this problem, it is necessary to thicken and reinforce the power transmission line, which is inconvenient

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a wind and partial wear-resistant device for power transmission lines. Background technique [0002] Under the excitation of wind load, the conductors and insulator strings of the transmission line vibrate, and the large wind swing will reduce the air gap between the conductor and the tower, the conductor and the tree. Once the critical value is exceeded, the discharge phenomenon will occur, reducing the The reliability of power supply poses a great risk to the normal operation of transmission lines. Therefore, it is of great significance for the safe operation of the power system to adopt reliable wind deflection measures in actual production. [0003] In the prior art, a high-voltage transmission line overhead wind and partial flashover device with publication number "CN206370670U" includes a fixed frame and a transmission line tower, a transmission line sleev...
