Transmission tower made of alumetized steel

Abstract

The invention provides a transmission tower made of alumetized steel. The transmission tower comprises a vertical tower body, a tower head and transmission wires, wherein the tower head is transversely arranged at the upper end of the tower body; the transmission wires are arranged on the tower head; the tower body is a frame structure formed by connecting angle steel main materials, angle steel inclined materials and angle steel transverse materials perpendicular to the angle steel main materials in a staggered manner; and a wire movement preventing device is arranged on each transmission wire. The alumetized steel transmission tower provided by the invention has the advantages that corrosion resistance of the transmission tower is improved, the service life of the transmission tower is prolonged by at least one year, manufacturing cost of the tower is reduced, and the wires of a transmission line are prevented from moving.

Description

Technical field [0001] The invention relates to power transmission equipment, in particular to an aluminized steel power transmission tower. Background technique [0002] With the rapid development of the power grid, the demand for transmission towers is also increasing. The operation and maintenance costs of transmission towers due to steel corrosion are very staggering. The atmospheric environment (coastal salt fog and chemical acid rain areas) causes serious corrosion of conventional transmission towers. It can be seen that the corrosion of the iron tower has caused a great waste of power transmission tower materials and energy, and has seriously affected the safety and reliability of power grid operation. Therefore, it is necessary to provide an aluminized steel transmission tower to prevent the transmission tower from corroding, causing loss of strength and reducing mechanical properties. [0003] After long-term observation and research, the inventor found that transmission ...

Problems solved by technology

[0002] With the rapid development of the power grid scale, the demand for transmission towers is also increasing. The operation and maintenance costs of transmission towers caused by steel corrosion are staggering. The atmospheric environment (coastal salt spray and chemical acid rain areas) leads to serious corrosion of conventional transmission towers.

It can be seen that the corrosion of the iron tower has caused a great waste of transmission tower materials and energy, which seriously affects the safety and reliability of the power grid operation.

Therefore, it is necessary to provide an aluminized steel transmission tower to prevent corrosion of the transmission tower, resulting in loss of strength and reduction in mechanical properties

[0003] The inventor finds through long-term observation and research that the steel structure with anti-corrosion function often adopts steel structure anti-corrosion by hot-dip galvanizing, and the existing power transmission tower will involve problems: 1. The traditional hot-dip galvanizing method consumes a lot of zinc and leaves zinc slag 2. There are problems of high energy consumption and serious pollution; 3. Hot-dip galvanized steel has poor anti-corrosion performance, insufficient service life and strength, and cannot meet the anti-corrosion requirements of transmission towers in extreme environments; 4. The node structure of the transmission tower is unreasonable, resulting in increased consumables, poor node strength and increased construction difficulty; 5. The performance of the anti-dancing device of the transmission tower is poor, and it cannot effectively suppress the simultaneous dancing of two adjacent conductors, which is easy to cause damage under severe weather conditions. Serious economic loss and social impact
