Description
Technical field
The present invention relates to a kind of method that can solve metal high voltage line icing, pass through more particularly, it relates to a kind of
Metal high voltage line surface forms based superhydrophobic thin films with the method solving icing problem.The invention still further relates to above-mentioned preparation surface have
The equipment of the metal high voltage line of based superhydrophobic thin films.
Background technology
The icing of transmission line of electricity and accumulated snow threaten the safe operation of electric power and communication network.Russian, Canadian, beautiful
State, Japan and China North Road and Midwest severe cold areas, the peace that the circuit that powerline ice-covering causes damages and thus causes
Full accident, brings great inconvenience usually to local life and production, and causes huge economic loss.Icing often causes defeated
Electric line falls bar (tower), broken string and the major accident such as insulator arc-over, and the safe operation to power system produces serious harm.I
State is one of serious country of powerline ice-covering, and the probability that circuit Harm Accident occurs is at the forefront in the world.
There are rare ice rain, many high-tension line icing in south China in 2008, causes power system on a large scale to be paralysed, make
National wealth and personal safety loss are become.Therefore, carry out ice-covering-proof technical research, develop reliable ice-covering-proof technology, thus
The problem solving metal high voltage line icing is very urgent.At present, the most generally use mechanical deicing, spread deicer, heating
Deicing and naturally passive 4 kinds of de-icing methods of deicing.Wherein mechanical deicing's efficiency is low, working strength big and is limited by weather and landform
System, safety coefficient is low, only as a kind of emergency method.And spread anti-freeze liquid or the salt of being usually in deicer method,
Soil being had pollution, ground is had corrosion, can only be coated with temporarily spread, timeliness is short.And heat deicing and the loss of electric energy relatively greatly and is deposited
In the biggest potential safety hazard, limit the application of the method.Naturally passive deicing refers in the painting of the surface of base material ice-covering-proof
Coating, reduces the ice adhesive force to substrate surface and the ice cover on surface, and recycling wind and elemental effect make ice come off.Mesh
Before, the development of anti-icing paint is one of focus of ice-covering-proof research, it has been developed that multiple anti-icing paint, but its application
Effect is the most bad.
Later, it has been found that, super hydrophobic material has ice-covering-proof effect.Wherein macromolecular material is to prepare super-hydrophobic table
A kind of important material in face.The method using macromolecular material to prepare super hydrophobic surface has a variety of.But preparation is super at present
These methods of hydrophobic surface or expensive starting materials used, or preparation condition is harsh, waste time and energy, or be difficult to prepare
Uniformly, large-area based superhydrophobic thin films, limit the actual application of said method, limit the application of super hydrophobic material.
Summary of the invention
For the deficiencies in the prior art, the invention provides the preparation method of a kind of ice-covering-proof metal high voltage line, the method
