Aerodynamic glass insulator and manufacturing method thereof

Abstract

The invention belongs to the field of insulators and especially relates to an aerodynamic glass insulator and a manufacturing method thereof. According to the invention, a coating is arranged on the surface of the aerodynamic glass insulator and comprises at least four layers from bottom to top, wherein the first layer is fluorocarbon resin, the second layer is nanometer silicon dioxide particles,the third layer is nanometer calcium carbonate particles, and the fourth layer is long-chain silane; the bottom surface of the fluorocarbon resin is adhered to the surface of the insulator; the bottoms of the nanometer silicon dioxide particles are embedded in the fluorocarbon resin; the bottoms of the nanometer calcium carbonate particles are embedded in the nanometer silicon dioxide particles;and the head of the long-chain silane is connected with the nanometer calcium carbonate particles or the nanometer silicon dioxide particles, and the tail of the long-chain silane extends outwards. The aerodynamic glass insulator has hydrophobic and antifouling functions.

Description

technical field [0001] The invention belongs to the field of insulators, in particular to an aerodynamic glass insulator and a manufacturing method. Background technique [0002] An insulator is a device installed between conductors of different potentials or between a conductor and ground potential, capable of withstanding voltage and mechanical stress, in order to increase the creepage distance. As a kind of insulator, aerodynamic glass insulator has good mechanical and electrical properties, and good insulation. However, in the process of use, it is often polluted, and the filth attached to the insulating surface is gradually dissolved in water under humid conditions, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator. Under the action of electric field, strong discharge occurs, and even surface breakdown occurs in severe cases. [0003] The surface of the aerodynamic glass insulator is a high-energy surface,...
