Abstract

The invention discloses a self-cleaning high-strength rod-shaped porcelain insulator. A high-aluminum porcelain insulator is used as a body, a layer of hydrophobic thin film material is coated on the high-aluminum porcelain insulator, and the high-aluminum porcelain insulator body and two hardware fitting accessories are connected by a cement adhesive. The self-cleaning high-strength rod-shaped porcelain insulator is high in mechanical strength, and the problem similar to a brittle failure of a core rod of the composite insulator does not occur; meanwhile, the properties such as the structure, strength and material of the insulator are not changed by a surface organic matter; and the self-cleaning high-strength rod-shaped porcelain insulator is high in adhesion, and the phenomenon that the properties are substantially reduced caused by coating / rubber falling-off is avoided.

Description

technical field [0001] The invention belongs to the field of electrical ceramics, in particular to a self-cleaning high-strength rod-shaped porcelain insulator. Background technique [0002] Pollution flashover accidents of porcelain insulators used in electrified catenary can cause multiple traction power supply systems to vibrate, disintegrate the power grid, and cause serious accidents such as large-scale power outages, railway operation interruptions, and outages. With the rapid development of electrified railway construction, it is becoming more and more important to solve the pollution flashover problem of catenary insulators. By rationally selecting the material of porcelain insulators and improving the structure of the insulators, the overall level of anti-pollution flashover of the catenary can be improved. [0003] The use of silicone rubber composite insulators with excellent hydrophobicity can effectively prevent pollution flashover, but the composite insulator ...
