Description

Porcelain insulator with lotus leaf micro-nano structure
Technical Field
The utility model relates to a porcelain insulator correlation technique field, in particular to porcelain insulator with lotus leaf micro-nano structure.
Background
The porcelain insulator is a line insulator which is most commonly and most important used, generally plays a role in insulation and fixation in a high-voltage overhead line, mainly comprises an iron cap, steel feet and a glue for porcelain parts with umbrella skirts, is an important component of a power transmission line, is an electric insulating part and an important structural support part, has the insulating property and the mechanical property and the configuration rationality thereof directly influence the safe and stable operation of the line, dust particles in the atmosphere deposit on the surface of the traditional insulator to form a dirt layer in the long-term operation of the traditional insulator, the resistance of the dirt layer is very large in dry weather, the insulating property cannot be reduced, but the surface of the traditional porcelain insulator has no hydrophobic structure, when the external environment has humid environments of rain, fog, dew and the like, soluble substances in dirt attached on the surface of the traditional porcelain insulator gradually dissolve in water, and then a conductive film is formed on the surface of the traditional porcelain insulator, under the action of an electric power field, a strong discharge phenomenon (flashover) occurs, so that a power system is paralyzed, and serious loss is caused to national economic production. Certain improvements to conventional porcelain insulators are needed.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art in the porcelain insulator, the utility model provides a rational in infrastructure, reduce fortune dimension cost, self-cleaning degree height, antifouling sudden strain of a muscle performance good have lotus leaf micro-nano structure's porcelain insulator.
The to-be-solved technical problem of the utility model is that: the porcelain insulator with the lotus leaf micro-nano structure comprises an insulator body, wherein an umbrella skirt is arranged on the outer side wall of the insulator body, a glaze layer is arranged on the outer surface of the insulator body, a micron mastoid layer is distributed on the surface of the glaze layer in order or at staggered intervals, and a nanoparticle layer covers the micron mastoid layer.
Further, the shape of the micron mastoid layer comprises a spherical shape, a triangular pyramid shape, a flower shape, a cylindrical shape, a cubic shape and a round mastoid shape.
Furthermore, the size of the micron mastoid layer is 3-20 microns, and the size of the nano particle layer is 60-190 nanometers.
Compared with the prior art, the utility model, use high temperature to stabilize ceramic powder (for example alumina, zirconia, mullite, zirconium silicate etc.), also can use useless ceramic powder to be main construction material, the cost is not high, it has high contact angle to construct the ceramic glaze face that the lotus leaf bionical mastoid process structure of receiving a little on ceramic glaze face, low roll angle has reduced water at the actual area of contact on surface by a wide margin, and just hydrophobicity and automatically cleaning performance are far higher than ordinary pottery behind the wear-resisting test, promote porcelain insulator's hydrophobic performance and glaze surface automatically cleaning ability.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, 2, 3 and 4, a porcelain insulator with a lotus leaf micro-nano structure, taking a butterfly insulator as an example, comprises an insulator body 1, wherein an umbrella skirt 2 is arranged on the outer side wall of the insulator body, connecting columns are arranged between the umbrella skirts, a glaze layer 3 is arranged on the outer surface of the insulator body, micro papilla layers 4 are distributed on the surface of the glaze layer in order or staggered intervals, nanoparticle layers 5 are covered on the micro papilla layers, as shown in fig. 2, 3 and 4, when different high-temperature stable ceramic powders (such as alumina, zirconia, mullite, zirconium silicate and the like) are used or waste ceramic powders are used, micro papilla layer structures with different shapes can be constructed on the glaze layer, the micro papilla layers are spherical, triangular conical and flower-shaped, and can also comprise cylindrical, cubic and circular papilla types, and the like, and the size (maximum diameter) of the micro papilla layers is 3-20 micrometers, the size of the nano particle layer is 60-190 nanometers, the ceramic insulator takes micron-sized ceramic waste as a raw material, and the micron-sized ceramic waste is fixed on a porcelain insulator glaze surface through an organic adhesive to prepare a porcelain insulator surface with a lotus leaf mastoid structure; the nano waste porcelain powder, the hydrophobic material and the organic adhesive are used as raw materials to prepare slurry, and the slurry is sprayed on the mastoid glaze surface to prepare the electric porcelain with the lotus leaf micro-nano hydrophobic structure. When the external environment has the conditions of rainwater or fog and the like with high humidity, the contact angle of a water drop on the surface of the porcelain insulator is larger than 160 degrees, the rolling angle is smaller than 5 degrees, and the water drop can slide and cannot be adhered to the insulator; when the insulator is stained, the stain can be dissolved in water drops or washed away by the water drops and is not stained with water; and after frosting and power frequency voltage tests, the self-cleaning capability of the porcelain insulator is still far higher than that of the traditional porcelain insulator.
The above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the specific embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
