Description

Technical Field

[0001] The utility model relates to the technical field of overhead lines, in particular to an overhead line conductor crossing protection device. Background Technique

[0002] The crossing of overhead line conductors means that in the power system, overhead lines need to cross certain obstacles, such as rivers, roads, railways, etc., and the protection device is a device used to protect the safety of overhead power lines when crossing other objects.

[0003] After retrieval, a patent with the publication number CN219892808U discloses an overhead line conductor crossing protection device, which includes: a load-bearing rope, the two ends of which are respectively fixed at a first position and a second position; a protection frame, having a limiting ring, the limiting ring is suspended on the load-bearing rope, and the limiting ring is used to accommodate the conductor, so that the conductor is always located in the limiting ring during the process of moving from the first position to the second position; a supporting net, which is arranged at the bottom of the limiting ring. The overhead line conductor crossing protection device of this application uses the limiting ring to accommodate the conductor, so that the conductor is always located in the limiting ring during the process of moving from the first position to the second position, and can support the accidentally dropped conductor through the limiting ring. A supporting net is also arranged at the bottom of the limiting ring, and through the blocking of the supporting net, the conductor can be insulated and isolated from the personnel or objects located below the supporting net, further avoiding the dropping of the conductor, so that the conductor is isolated and protected from the personnel or objects below, and the construction safety during the conductor laying process is improved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
