Embodiment Construction

[0026] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, a herringbone column substation frame lattice lightning rod includes a herringbone column 1 and a lightning rod 2. The lightning rod 2 includes a lightning rod tip 21 and a main carrier 22 whose main body is a lattice structure. The lightning rod tip 21 is arranged on the main carrier At the top of the body 22, the main supporting body 22 adopts a round steel lattice structure, which is formed by intersecting welding between the web and each main chord, and the bottom end of the main supporting body 22 is connected with a connecting plate connected with the herringbone column 1 3. The connecting plate 3 is fixedly connected to the top of the herringbone column 1 through the fastener 4, and the bottom end of the main carrier 22 is provided with a fixed part 5 for fixing the connecting plate 3, and the fastener 4 is connected to the fixed part 5. The fixed part is connected with the con...

Abstract

The invention relates to a herringbone column power transformation framework lattice type lightning rod. The herringbone column power transformation framework lattice type lightning rod comprises a herringbone column and a lightning rod; the lightning rod comprises a lightning rod tip and a main bearing body; the lightning rod tip is arranged at the top end of the main bearing body; the main bearing body adopts a round steel lattice type structure and is formed by welding a web material and each main chord member; a connecting plate is connected to the bottom end of the main bearing body; and the connecting plate is fixedly connected with the top end of the herringbone column through a fastening part. The herringbone column power transformation framework lattice type lightning rod has the advantages that: as the lightning rod is composed of the lightning rod tip and the main bearing body and the main body of the main bearing body adopts a lattice form, the lightning rod per se has a greater rigidity when being compared with an existing structural style with a single steel tube at the top of the herringbone column; the top of the lightning rod generates smaller displacement at the presence of the same gale load effect, and better stability is obtained; a fatigue phenomenon is not easy to generate in the presence of long-term cooperation; and as damage of partial rod part or welding seam cannot directly result in damage of the whole lightning rod, better safety guarantee is obtained.

Description

technical field [0001] The invention relates to a lattice type lightning rod of a herringbone column substation frame. Background technique [0002] Domestic 500kV, 330kV, 220kV and 110kV outdoor substation structures generally adopt steel pipe herringbone column structure, and the lightning rods set on the upper part are all of single steel pipe structure. Large swing, under long-term action, the steel pipe of the lightning rod and the connecting bolts, welds, etc. are prone to fatigue. Finally, the strength of the lightning rod is reduced and the ring is broken. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a herringbone column substation frame lattice type lightning rod, which solves the problems of easy fatigue damage and unreliable connection of the existing lightning rod. [0004] In order to solve the above-mentioned technical problems, the present invention is achieved through the following technical ...
