A self-cleaning insulator

Abstract

The invention discloses a novel self-cleaning insulator and belongs to the field of power transmission equipment. The novel self-cleaning insulator comprises an insulating piece umbrella skirt and an insulator column, wherein the insulating piece umbrella skirt comprises an upper umbrella skirt and a lower umbrella skirt; an annular umbrella edge downwards stretches out of the lower surface of the upper umbrella skirt; the insulator column is located just below the upper umbrella skirt; the lower umbrella skirt is arranged at the lower end of the insulator column; bulges which are arrayed orderly are arranged on the outer surface of the insulator column and the upper surface of the lower umbrella skirt. The novel self-cleaning insulator can be used for collecting rainwater to flush away accumulated dust, so that the self-cleaning function is realized and the manpower and material resources are saved; a pollution flashover condition is avoided; air can blow through the outer surface of the insulator column and the upper surface of the lower umbrella skirt through a gap part between the adjacent bulges, so that the outer surface of the insulator column and the upper surface of the lower umbrella skirt can be blown and cleaned by the air under the condition of no rainwater; the condition that the dust is seriously deposited on the insulator of drought regions or regions with less rainwater is prevented.

Description

technical field [0001] The invention belongs to the field of power transmission equipment, and more specifically relates to a self-cleaning insulator. Background technique [0002] Disc suspension insulators are a type of insulators used in transmission lines. Among all kinds of line insulators, disc suspension insulators are the most important and the most used one. Insulators are mainly used in overhead transmission lines to insulate and suspend conductors. When insulators are used, they are mainly subjected to the combined effects of tension, vibration, system voltage, overvoltage and various atmospheric conditions. The structure of the insulator can be divided into two parts: the top part and the shed of the insulator. The shed of the insulating part is the visible part of the insulator except the top part, and the shed of the insulating part is generally disc-shaped. The top part of the insulator mainly endows the insulator with mechanical strength and internal insu...

Problems solved by technology

[0003] There are many edge cleaning devices, most of which are cleaned manually with the help of external tools, but this method is time-consuming and labor-intensive

The slope of the upper surface and the lower surface of the shed of the composite insulator in the prior art is relatively gentle, and the anti-pollution ability is poor, especially in a dynamic environment, the pollution accumulation characteristics are poor, and the cleanliness of the product surface cannot be effectively guaranteed, and it is easy to Cause pollution flashover, especially when operating safely under high wind speed conditions, the relatively dense shed structure design is easy to connect rainwater into chains under heavy rain or heavy rain, causing rain flash
