Description

Technical Field

[0001] The utility model relates to the field of power transmission lines, in particular to an anti-flashover insulator. Background Art

[0002] During long-term operation of insulators, dust particles in the atmosphere are deposited on their surfaces to form a contamination layer. In dry climates, the resistance of the contamination layer is very large and the insulation performance will not be reduced. However, under meteorological conditions such as fog, dew, light rain, and snow, the electrolyte in the contamination layer becomes wet, which increases the surface conductivity and reduces the insulation performance. The ash and other substances in the contamination layer retain moisture, which promotes further moisture in the contamination layer, thereby dissolving more electrolytes and causing flashover discharge on the wet surface of the insulator, referred to as contamination flashover. The contamination accumulation on the surface of transmission line insulators is inevitable. A search of the application number CN201621467943.6 discloses an anti-contamination insulator comprising an insulator body, a concave structure, a protrusion, a protective layer, an insulating fleece and a groove, and the groove and The concave structures are respectively arranged on the inner and outer walls of the insulator body; the upper surface of the concave structure is provided with a protrusion; the side wall of the concave structure is connected to the lower surface by an arc surface; the upper and lower surfaces of the concave structure are downwardly inclined slopes; the surfaces of the insulator body and the concave structure are provided with hydrophobic insulating fleece; the upper surface of the insulator body is provided with a transparent protective layer of corrugated structure, which can effectively prevent dirt accumulation, facilitate detection, and is snow-proof, waterproof, and anti-fouling, and has a large creepage distance. However, the above description still has the following defects in actual use: the insulator is not convenient to install and connect with cables of different sizes when in use, and the overall structure is relatively fixed, and its structure cannot be installed and disassembled. Therefore, it is necessary to design a practical anti-flash pollution insulator. Utility Model Content
