Suspension insulator string type wind-power full-automatic sweeper for power transmission lines

Abstract

The invention discloses a suspension insulator string type wind-power full-automatic sweeper for power transmission lines. The sweeper comprises a sweeper wheel ring, wind-power rotating blades, lifting blades and internal hairbrushes, wherein the sweeper wheel ring is of a circular ring structure and sleeves a line suspension insulator string, the internal hairbrushes are uniformly distributed in the sweeper wheel ring, one ends of the internal hairbrushes are fixed on the inner wall of the sweeper wheel ring, and the other ends of the internal hairbrushes are distributed to extend towards the center of the sweeper wheel ring; and the lifting blades are uniformly distributed on the outer wall of the sweeper wheel ring, and the wind-power rotating blades are arranged on the vertical directions of the lifting blades and are used for generating lifting airflow under the action of wind power so as to drive the whole sweeper to rotate or simultaneously go up and down. By utilizing a wind power and rotary ascending (descending) principles, line insulators can be automatically swept under the action of the wind power, the sweeper can be repeatedly used throughout the year, and the manual setting of a power source and the manual maintenance are omitted; and the sweeper is important invention and innovation in the hot-line sweeping of insulator strings of the power transmission lines.

Description

technical field [0001] The invention relates to a wind-powered automatic cleaning device for suspended insulator strings of power transmission lines. Background technique [0002] In recent years, with the development of industry and the deterioration of the atmospheric environment, long-term and large-scale smog often break out, and power grids across the country often have pollution flashover trips on transmission lines, especially pollution flashover trips on transmission lines of 220kV-1000kV main power grids. Seriously affect the safe and stable operation of the power system. [0003] Transmission line pollution flashover is the electric porcelain surface of transmission line insulator strings, which is polluted by solid, liquid and gaseous conductive substances, which increases the conductance of the insulating layer surface, increases the leakage current, and generates partial discharge. The partial discharge developed into arc flashover, which is called pollution fl...

AI Technical Summary

Problems solved by technology

[0004] At present, the live cleaning of transmission line insulator strings cannot be carried out at home and abroad. The main reasons are as follows: 1. The transmission lines are all in the wild, crossing farmland, mountains and rivers, and there is no power source at the line tower

2. The transmission line towers are all very high, generally 50 meters to 100 meters high, and it is impossible for personnel to clean the insulator strings on the ground

3. The insulator strings of transmission lines are very long, generally between 5 meters and 9 meters. Even if a person climbs on the cross-arm of the iron tower, it is impossible to clean the insulator strings with electricity through the operating rod or the like

4. Even if there is a power failure, manually climb up the insulator strings for cleaning, because a line spans hundreds of kilometers, hundreds or even thousands of base towers, and one person can only clean 1-2 and the insulator strings on the tower in a day, which is huge. tactics are unrealistic
