Problems solved by technology

[0003] At present, the anti-pollution flashover work in China mainly focuses on the installation of anti-pollution insulators, regular cleaning of insulators, increasing the creepage ratio distance, and painting RTV paint, etc., but these methods are passive or regularly implemented
At the same time, no anti-pollution method for installing cleaning devices on insulators has been proposed.
With the aggravation of atmospheric environmental pollution and the deterioration of climatic conditions, the existing anti-pollution measures cannot fully meet the requirements of anti-pollution work
For example, increasing the creepage distance is limited by actual conditions, it is difficult to determine the pollution level of each area, and it is impossible to increase the creepage distance without limit; although painting RTV paint can achieve certain effects, RTV paint has certain A large amount of repeated painting will increase the burden on the management department; planned regular cleaning cannot prevent the occurrence of pollution flashover, and sometimes pollution flashover accidents have occurred on the line before cleaning

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-2 As shown, a kind of anti-pollution cleaning device for external insulation of power transmission and transformation equipment of the present invention includes cleaning sheet 2, crawler belt 3, brush head 4, fixed ring 5, cross bar 6, motor drive device 7, pollution detection device 8, belt Wheel 10 and drive shaft 11.

[0022] The shape of the cleaning sheet 2 is "C", the brush head 4 is fixed on the inner side of the "C" shape of the cleaning sheet 2, and the outer edge of the brush head 4 is insulated from the outer edge of the power transmission and transformation equipment. 1 The shapes are matched, and the fixing ring 5 is divided into an upper fixing ring and a lower fixing ring. The upper fixing ring is set on the central axis of the upper part of the umbrella plate 1 of the insulator, and the lower fixing ring is set on the central axi...

Abstract

The invention relates to an outer insulating antifouling cleaning device for power transmission and transformation equipment. The device comprises cleaning pieces (2), tracks (3), brushing heads (4), fixed rings (5), a horizontal rod (6), a motor driving device (7), a foul detecting device (8), belt wheels (10) and a transmission shaft (11), the belt wheels (10) are fixed on the transmission shaft (11) and meshed with the tracks (3), the horizontal rod (6) is fixedly mounted at the uppermost end of a central insulator shaft, and the foul detecting device comprises an ultraviolet sensor, a single chip microcomputer and a second storage battery. The outer insulating antifouling cleaning device for the power transmission and transformation equipment can effectively clear foul on the surface of an insulator to lower probability of flashover.

Description

technical field [0001] The invention relates to an anti-pollution cleaning device for external insulation of power transmission and transformation equipment. More specifically, the present invention relates to an insulator antifouling cleaning device. Background technique [0002] Most of the high-voltage grid operation failures are caused by poor insulation, and the high-voltage grid insulator is the weak link of the high-voltage grid insulation. Pollution flashover is caused by the dirty and damp state of the insulator surface to a certain extent. It is a common phenomenon that occurs in high-voltage lines and substations, and it is a major threat to the safe operation of the power grid. Due to the great harm and wide area of ​​pollution flashover accidents, a large accident will often cause multiple lines in the same area to trip at the same time. Therefore, the power sector has regarded the prevention of pollution flashover accidents as an important task to ensure the s...
