Self-cleaning insulator

Abstract

A self-cleaning insulator comprises insulator umbrella skirts (2) and an insulator column (1) and is characterized in that the insulator umbrella skirts (2) are formed by a plurality of sector-shaped units (21). Ridges (22) are formed at the junction positions of the adjacent sector-shaped units (21), the heights of the upper surfaces of the sector-shaped units (21) are sequentially decreased from the insulator column (1) to the edges, and the cross sections of the upper surfaces of the sector-shaped units (21) are arcs with the high ridges (22) and the concave middles. Compared with the prior art, the ridges are formed at the junction positions of the adjacent sector-shaped units, the middles of the sector-shaped units are sunken downwards, and the central positions are higher than the edge positions. Dust cannot be accumulated at the ridge positions and can be accumulated at the sunken positions, so that when it rains, the accumulated dust can be washed away along with rain, the self-cleaning function is achieved, and manpower and material resources are saved. The rain flows down from the most concave positions at the centers of the sector-shaped units, the rain is unlikely to be connected into a chain shape even during heavy rain or rainstorms, and rain flashover is prevented from being caused.

Description

Technical field [0001] The invention relates to a power transmission equipment, in particular to a self-cleaning insulator. Background technique [0002] There are many edge cleaning devices, most of which are manually cleaned with external tools, but this method requires time and effort. [0003] The slopes of the upper and lower surfaces of the sheds of composite insulators in the prior art are relatively gentle, and their anti-fouling ability is poor. Especially in a dynamic environment, they have poor fouling characteristics and cannot effectively ensure the cleanliness of the product surface. This can cause pollution flashovers, especially when operating safely under high wind speeds. The denser umbrella skirt structure design is easy to chain in heavy rain or heavy rain, causing rain flashes. Summary of the invention [0004] In view of the above problems, the present invention provides a composite insulator with an anti-fouling umbrella skirt to solve the problem of ...
