Anti-icing nano functional wire

Abstract

The invention discloses an anti-icing nano functional wire. The wire is provided with a layer of an aluminum substrate (1). A lower honeycomb aluminum oxide layer (21) and an upper honeycomb aluminum oxide layer (22) are stacked on the upper layer of the aluminum substrate (1). Diameters of upper honeycomb holes (42) of the upper honeycomb aluminum oxide layer (22) are smaller than those of lower honeycomb holes (41) of the lower honeycomb aluminum oxide layer (21), so that the upper honeycomb aluminum oxide layer (22) can plug the lower honeycomb aluminum oxide layer (21). Besides, the lower honeycomb holes (41) are filled with mixed nanoparticles formed by mixing nano heating functional particles, nano phase transition particles and nano polyelectrolyte particles. The wire achieves an anti-icing effect by heating spontaneously or reducing a water condensation point, the structure and properties are stable, the binding force of the wire with the aluminum substrate is good, and the wire is reliably protected. After the wire is connected to a current, the anti-icing effect is remarkable, so that the wire is popular with users.

Description

technical field [0001] The invention belongs to the technical field of conductive materials, and in particular relates to an anti-icing nanometer functional wire which is beneficial to the safe operation of a power grid. Background technique [0002] Icing of transmission lines can easily cause serious grid safety accidents such as line disconnection and tower collapse. At the beginning of 2008, the long-term and large-scale ice and snow freezing disaster occurred in southern my country, resulting in large-scale icing of transmission lines. A large number of transmission lines were disconnected and towers collapsed, power supply was interrupted on a large scale, and direct economic losses exceeded 100 billion yuan. At present, the research on anti-icing of power grid is mainly concentrated in the fields of current melting ice and anti-icing coatings. The Chinese patent literature with the publication number CN201234105Y introduces a transmission line ice melting device, wh...

Problems solved by technology

However, all the above-mentioned inventions and research results are based on the film-forming principle of organic resin materials. Resin materials have high requirements on construction technology and poor weather resistance, which may cause poor field application effects or short-term failures, resulting in Steel-cored aluminum stranded wires and other aluminum transmission wires are still prone to icing problems in low-temperature rain and rime weather
