Web member structure shaped like Chinese character 'mi' and extra-high voltage converter station direct current field polar line tower

Abstract

The invention discloses a web member structure shaped like the Chinese character 'mi' and an extra-high voltage converter station direct current field polar line tower. The web member structure shaped like the Chinese character 'mi' comprises a transverse web member and a plurality of diagonal web members, the transverse web member is horizontally connected between two adjacent stand columns of a tower body, and the diagonal web members are connected between rod bodies of the transverse web member and the stand columns of the tower body; the upper side and the lower side of the transverse web member are each connected with two diagonal web members, and the four diagonal web members are converged and connected to the same position of a member body of the transverse web member; and a plurality of groups of web member structures shaped like the Chinese character 'mi' are stacked on the stand columns of the tower body, and the diagonal web members of the upper and lower adjacent groups of web member structures shaped like the Chinese character 'mi' are converged and connected to the same position of the tower body. According to the extra-high voltage converter station direct current field polar line tower, the web member structure shaped like the Chinese character 'mi' is arranged on the tower body below the polar line hanging point elevation. The steel consumption can be reduced, and the stability of the direct current field polar line tower structure is effectively improved.

Description

technical field [0001] The invention belongs to the field of converter station construction, and relates to a rice-shaped web structure and a DC field pole line tower of an ultra-high voltage converter station. Background technique [0002] The DC field pole line tower of conventional UHV converter stations adopts a square lattice column, and the web rod adopts a W-shaped arrangement. Greatly improved, it is more difficult to control the structural indicators such as the displacement of the pole line tower, the strength of the main rod, and the slenderness ratio of the web rod in the conventional way, and the amount of steel consumed is large, and the economy is poor. Therefore, the web structure adopting W-shaped arrangement is not the optimal structure form. Contents of the invention [0003] The purpose of the present invention is to provide a rice-shaped web bar structure and DC The field pole line tower can save the amount of steel to the greatest extent while meeti...

[0002] The DC field pole line tower of conventional UHV converter stations adopts a square lattice column, and the web rod adopts a W-shaped arrangement. Greatly improved, it is more difficult to control structural indicators such as the displacement of the pole line tower, the strength of the main rod, and the slenderness ratio of the web rod in the conventional way, and the amount of steel consumed is large, and the economy is poor

Therefore, the web structure with W-shaped arrangement is no longer the optimal structural form
