Problems solved by technology

[0002] With global warming, natural disasters occur frequently in many areas, such as the rain, snow and freezing disasters in southern China in early 2008; The collapse of towers and disconnection of transmission lines not only caused huge property losses to the country, but also seriously affected industrial and agricultural production and the normal life of the people.

Embodiment 1

[0067] The present invention will be described in further detail below by taking the 500kV double-circuit power transmission line on the same tower repaired as an example.

[0068] According to the icing situation, determine the load on the tower, and determine the selection of aluminum alloy double-column towers containing materials according to the following mass percentages:

[0069] Si: 0.5%, Fe: 0.5%, Cu: 4.1%, Mn: 0.7%, Mg: 1.5%, Ni: 0.1%, Zn: 0.3%, Ti: 0.15%, and the balance is Al. This material is light in weight, easy to transport, high in load, safe and reliable, not easy to corrode and rust, and has a long service life.

[0070] Among them, the size of column top plate 1 and bottom plate 2 is 900×900mm, and the thickness is 14mm. Parts 4 are connected by welding, the length of each column is 6m, and the connecting bolts between the columns are M24 hot-dip galvanized bolts.

[0071] First, set up the double columns in the transverse direction as follows: First, ins...

Abstract

The invention provides a tower column for fast first-aid repair. The tower column is used for a suspension tower, a tension-resistant tower or a suspension corner tower. The assembly number of columns in the horizontal and vertical direction is determined according to the voltage class and load of a repaired line and the distance between a cross arm of the repaired line and the ground. The column comprises a main column and connection pieces arranged at two ends of the main column, and the connection pieces are arranged in parallel and perpendicular to the axis of the main column. The tower column is characterized in that the cross section of the main column is polygonal or round, a vertical piece formed by connecting S-shaped or X-shaped reinforcing pieces is arranged in the main column in the axis direction. The tower column for fast first-aid repair adopts modularized assembly, is applicable to repair of power transmission lines of different voltage levels in the mountainous and hilly regions and the like, and can greatly improve line repairing efficiency and quality.

Description

technical field [0001] The invention relates to a pole and tower column, in particular to a quick repair pole and tower column. Background technique [0002] With global warming, natural disasters occur frequently in many areas, such as the rain, snow and freezing disasters in southern China in early 2008; Cause the transmission line to fall tower, break the line, not only cause huge property loss to the country, but also cause serious impact to industrial and agricultural production and the normal life of the people. [0003] The scale of cross-regional power grids is increasing day by day, the meteorological, geological, and topographic conditions of the line corridors are complex, and disasters such as wind and ice seriously threaten the safe operation of the line. However, the transmission capacity of the line is large. Once a power outage occurs, it will have great impact on economic construction and social life Therefore, it is strongly required to restore the power s...
