Icing-resistant paint and preparation method thereof, aluminium wire and preparation method thereof and transmission conductor

Abstract

The invention provides an icing-resistant paint and a preparation method thereof, an aluminium wire and a preparation method thereof and an ice and snow resistant transmission conductor. The icing-resistant paint is prepared by the following steps: mixing ethanol and hexane in a volume ratio of (6-18): (1-5) to obtain a transparent mixed solvent; mixing base-material and silicon fluoride in a volume ratio of (80-120): (1-15) and stirring uniformly to obtain the icing-resistant paint. The icing-resistant paint has hydrophobicity; a surface of an aluminium wire is coated with a layer of the icing-resistant paint; an outermost layer of an ice and snow resistant transmission conductor is wired by the aluminium wire coated with the icing-resistant paint, so as to reduce icing anchoring strength. Accordingly, water (freezing rain) dos not adhere on the transmission conductor, so as to reduce the possibility of ice layer formation on the transmission conductor and further reduce influences of ice and snow disaster on the transmission conductor.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an anti-icing coating and a preparation method, an aluminum wire containing the anti-icing coating and a preparation method, and an anti-ice and snow electric transmission wire. Background technique [0002] Before and after the Spring Festival in 2008, various places in southern my country suffered from severe rain, snow and freezing disasters that had not happened in 50 years. Power transmission and transformation facilities in Central China, East China, and Southwest China are seriously covered with ice, especially in Hunan, Hubei, Anhui, Zhejiang, Sichuan, Guizhou, Guangxi, Jiangxi and other places where tower collapses, disconnections, and trips have occurred. According to the report of China Electric Power News, as of February 29, 2008, a total of 36,740 power lines were out of service in the national power grid system due to the ice disaster (including 11...

Problems solved by technology

However, the anti-ice and snow wire has the following disadvantages: first, the price of PTC material is relatively high, which causes the high cost of this anti-ice and snow wire, which is not conducive to popularization and application

Second, only when the conductivity of the PTC material is better than that of the line conductor (such as aluminum wire), the current will flow on the PTC material. However, the PTC material is a semi-conductive material that cannot achieve automatic temperature control conductivity. Flow on the conductor, which reduces the heating performance of the PTC material, and also reduces the function of anti-ice and snow

[0009] These deicing methods provided by the prior art are not only energy-consuming, time-consuming, and labor-intensive, but also have low efficiency, high cost, and are not easy to implement on a large scale. They are relatively mature at home and abroad and can be widely used in deicing of transmission lines Ice and ice-melting methods are also limited
