Automatic cleaning device and method for high-voltage transmission line insulator

Abstract

The invention discloses an automatic cleaning device and method for a high-voltage transmission line insulator. The automatic cleaning device comprises an insulating brush head, a main insulating rod, a rotary connecting shaft and an electric wrench, wherein the insulating brush head is fixed at the top end of the main insulating rod; the electric wrench is fixed at the bottom end of the main insulating rod; the main insulating rod is of a multi-section type and can be lengthened through a multi-connection connector; the main insulating rod is hollow and penetrates through the rotary connecting shaft; the rotary connecting shaft is arranged at the top end of the main insulating rod and is connected with the insulating brush head through a bevel gear; the rotary connecting shaft is arranged at the bottom end of the main insulating rod and is connected with the electric wrench through a concave-convex connector; and the electric wrench is started to drive the rotary connecting shaft to rotate and then the rotary connecting shaft is transmitted to the insulating brush head through the bevel gear to drive the insulating brush head to rotate. The device disclosed by the invention has the advantages of small size, simple structure, strong practicability and high automation degree; the method has the advantages of novelty, good effect and high industrial application value. Dirt on the surface of the insulator is cleaned in all directions through optimizing and automatically controlling a movement route of the brush head.

Description

technical field [0001] The invention belongs to the field of power grid maintenance, and in particular relates to an automatic cleaning device and method for high-voltage transmission line insulators. Background technique [0002] The operating conditions of transmission lines are harsh. Not only are they subjected to severe weather such as thunderstorms and strong winds all year round, but they are also affected by pollution in the air, resulting in dirty insulators on transmission lines, and insulator flashovers and other faults are easily caused in rainy days. In heavily polluted areas, the operation of insulators is under great threat, and it is very important for the operation and maintenance of insulators. Especially in the operation and maintenance of important long-span transmission lines or "three-span" and important user lines, it is necessary to pay close attention to the contamination of insulators to avoid surface flashover or breakdown caused by pollution and g...

AI Technical Summary

Problems solved by technology

Mechanical live cleaning refers to the use of professional tools and equipment to drive the brush to the surface of the insulator for cleaning. However, the current mechanical live cleaning devices are generally cumbersome and cumbersome to operate, requiring the cooperation of multiple people, and are not suitable for steel pipe towers, etc. Tower type, not suitable for cleaning insulators in complex outdoor environments
