Pollution flashover-prevention, corrosion-prevention and freezing-prevention electric tower and surface treatment method thereof

Abstract

The invention belongs to a technology of high-voltage or extra high-voltage power transmission overhead lines for electric power and wind power generation poles and towers, and relates to a pollution flashover-prevention, corrosion-prevention and freezing-prevention electric tower. The pollution flashover-prevention, corrosion-prevention and freezing-prevention electric tower is characterized by comprising a plurality of steel poles arranged together by bolts and flanges; a shot blasting-treated inner treatment layer, a sprayed epoxy zinc rich primer layer, an epoxy micaceous iron intermediate coat layer and a fluorocarbon finish paint layer are arranged on each steel pole matrix from inside to outside in sequence. The Pollution flashover-prevention, corrosion-prevention and freezing-prevention electric tower has the beneficial effects that the technical difficulties that the surfaces of the steel poles of the tower are hydrophilic because of being galvanized and are extremely easy to freeze at low temperature are overcome. The tower, the steel pole and a wind power generation tower tube produced by the technology are capable of achieving the goals of corrosion prevention, pollution flashover prevention and freezing prevention, respectively have a service life and are also economic and practical.

Description

technical field [0001] The invention belongs to the technology of high-voltage or ultra-high-voltage power transmission and transformation overhead or wind power generation towers and towers, and relates to an anti-fouling, anti-corrosion, anti-icing power tower and a surface treatment method thereof. Background technique [0002] Among the disclosed technologies, some of the current power towers and wind power towers are traditional cement poles, and some are made of iron or steel steel poles and towers. The anti-corrosion adopted by them is hot-dip galvanized or hot-sprayed galvanized technology. , There are also some external painting techniques, its weakness is that it is not resistant to radiation, not resistant to pollution flashover, the surface will turn black after a long time, and it is not water-repellent, and it is easy to freeze when it sees water in winter. Most of the towers whose surface is treated with paint are improperly selected and the spraying p...

AI Technical Summary

Problems solved by technology

In the case of freezing, the ductility of steel components will decrease due to low temperature and become fragile, especially the tensile strength will decrease, the bending stress will decrease, and the icing on the surface of the transmission wire will greatly increase the tensile force between two adjacent iron towers. increased, which led to the collapse of a large area of ​​steel towers and steel poles
