Combined anti-pollution flashover insulator

Abstract

The invention relates to a combined anti-pollution flashover insulator. The combined anti-pollution flashover insulator includes an umbrella-shaped insulator assembly and metal bases; the umbrella-shaped insulator assembly is divided into an upper part and a lower part, wherein the upper part is set in a manner that two insulators are connected onto a rectangular metal seat, and the lower part is set in a manner that one insulator is connected onto a triangular metal seat; the insulator of the lower part is connected with the rectangular metal seat; the surface layers of the insulators are provided with a layer of anti-pollution flashover paint; electroceramic sealing silicone rubber is adopted as an adhesive; the anti-pollution flashover paint is room temperature vulcanized silicone rubber; the thickness of the anti-pollution flashover paint ranges from 0.1 to 1 mm; the two insulators of the upper part are arranged at two sides of the rectangular metal seat; the top of the insulator of the lower part is connected with the middle of the rectangular metal seat, and therefore, the hydrophobic migration performance of the combined insulator can be improved, insulation level can be increased, and pollution flashover can be effectively prevented; and the surfaces of the insulators are provided with the anti-pollution flashover paint, and therefore, the problem of pollution flashover caused by air pollution can be effectively prevented.

Description

technical field [0001] The invention relates to high-voltage electric porcelain power transmission equipment, in particular to a combined anti-pollution flashover insulator. Background technique [0002] An insulator is a special insulation control that plays an important role in overhead transmission lines. The insulators used today will generally disappear due to various electromechanical stresses due to environmental changes, making the insulators unable to produce their own important functions, which will damage the service life and operating life of the entire line, and will also cause air pollution. Pollution flashover problems have caused large-scale and long-term power outages, resulting in major economic losses. For this reason, it is particularly important to design an insulator that will not cause pollution flashover problems due to the disappearance of various electromechanical stresses and air pollution problems due to environmental changes.
