Problems solved by technology

However, in the existing ceramic insulators, the glaze is prone to air bubbles and uneven glazing during use, resulting in a small number of pores on the surface of the porcelain insulator, which is not smooth enough, easy to stain, and difficult to clean, resulting in poor anti-pollution flashover effect. Damage to insulators can lead to frequent accidents
Based on the current air pollution is becoming more and more serious, pollution flashover accidents occur frequently, which greatly shortens the service life of ceramic insulators, and at the same time increases the maintenance cost of insulators, affects the normal operation of the railway power grid, and reduces economic benefits

The super-hydrophobic coating has good hydrophobicity and a self-cleaning capacity, water drops can adsorb pollutants such as dust and bacteria adhering to the surface of the insulator, the surface of the insulator is kept clean all the time, and the anti-pollution flashover performance of the insulator is greatly improved.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to an anti-pollution flash porcelain insulator and a preparation method thereof. Background technique [0002] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. It is a special insulation control designed to increase the creepage distance and can play an important role in overhead transmission lines, usually made of glass or ceramics. Insulators made of ceramics are porcelain insulators. [0003] Porcelain insulators have the advantages of high mechanical strength, stable chemical properties, good insulation performance, and good corrosion resistance, making them the most widely used in the insulator industry, and their use in railway traction network power systems is increasing. However, the natural environment in my country is relative...
