Embodiment Construction

[0025] In order to make the structure and composition of the present invention clear to your examiner, as well as the overall operation mode, the description is as follows in conjunction with the drawings:

[0026] The 500kV same-tower double-circuit compact linear tower described in the present invention is a brand-new tower type different from previous tower types. The determination of the size of the tower head depends on the layout of the conductors. Therefore, on the basis of the analysis of the 500kV conventional drum-shaped tower with double circuits in the same tower in my country, after the research and technical and economic comparison of various tower head layout schemes, in many schemes Among them, a brand-new tower-type technical solution of the T-shaped tower of the single-layer cross-arm of the present invention has been developed.

[0027] The tower head layout of the 500kV double-circuit parallel tower compact transmission line tower head, due to the characteri...

Abstract

The invention relates to compact double straight line electric power pylon. It adopts compact parallel double backward cam arrangement to lay conducting wire, negative protection angle to lay ground wire which can effectively reduce pylon height, increase 500kV parallel transmission line thunder resistance, running safe reliability. Compared with the conventional drum type straight line pylon, the 500kV compact double straight line can reduce steel product consumption by 30%, basal concrete consumption by 10%.

Description

technical field [0001] The invention relates to a power transmission equipment, especially a brand-new power transmission tower used in a 500 kV double-circuit power transmission line on the same tower. Background technique [0002] At present, the straight-line towers used in my country's 500 kV double-circuit transmission lines on the same tower are conventional straight-line towers with three-phase conductors arranged vertically and suspended on both sides of the tower. Under the premise that the distance between the wire and the ground meets the requirements of the regulations, the height of the iron tower usually reaches 60m-70m, and the average line corridor occupied is 22m. [0003] Such as figure 1 As shown, the design height of the existing conventional double-circuit 500kV line towers on the same tower is often more than 60m, which not only affects the lightning protection ability, but also one of the reasons for the high steel consumption index of the previous 50...
