Abstract

The invention provides a high-voltage composite insulator in order to solve the problems that anti-icing capacity is insufficient and scale depositing prevention capacity rapidly disappears as time goes by existing in the prior art. The insulator is formed by a ceramic substrate, a thermistor material layer and a photocatalytic nanometer material layer. The insulator has good anti-icing performance and scale depositing prevention performance. A surface coating layer adheres to a body firmly and is not prone to falling off, heat is generated from the thermistor material layer by means of weak leakage currents in the rain and snow weather, and therefore the phenomenon that the surface of the insulator is iced is reduced.

Description

technical field [0001] The invention relates to an anti-fouling high-voltage composite insulator coated with a waterproof and anti-icing coating and a preparation method thereof. Background technique [0002] Insulators in transmission lines are generally exposed to the air during use, and dust particles, saline and alkali particles, bird droppings, sulfur and nitrogen oxides and other substances in the air will be adsorbed on the surface of the insulator, thereby reducing the breakdown voltage of the insulator. Natural rain, snow, smog and other weather will make the dirt attached to the surface of the insulator absorb moisture, thereby further increasing the leakage current on the surface and causing pollution flashover. [0003] Commonly used anti-pollution flashover measures for insulators include regular cleaning or cleaning of accumulated pollution, increasing creepage ratio, spraying anti-fouling paint, etc. Among them, spraying anti-fouling materials is the main mea...
