Problems solved by technology

[0003] As one of the important equipment of transmission lines, insulators are responsible for the important tasks of suspending wires and insulating towers. The suspended porcelain insulators produced are used in high-voltage, ultra-high-voltage and ultra-high-voltage transmission lines all over the world, providing safe operation of transmission lines in various countries. However, since insulators are mainly used outdoors, the environment in which they are located is relatively harsh, and insulators are more likely to be polluted during use, and pollution flashover accidents of insulators in power systems have become increasingly prominent. Contaminative substances with conductive properties will greatly reduce the insulation level of insulators after being damp in wet weather. Flashover accidents that occur under normal operation usually require timely cleaning of the insulator surface. However, the existing insulators with cleaning effects , when the cleaning brush is used for a long time and wears out, the entire cleaning structure needs to be replaced. The cleaning brush cannot be disassembled separately, and the applicability and practicability are limited. At the same time, it is not possible to select appropriate power parts according to regional differences to ensure power Therefore, the object of the present invention is an insulator with self-cleaning effect for overhead transmission lines, so as to solve the problem that traditional cleaning brushes and power parts cannot be disassembled

Abstract

The invention relates to the technical field of overhead transmission line insulator cleaning, in particular to an insulator with a self-cleaning effect for an overhead transmission line, which comprises a cleaning part. At least a fixing ring is arranged in the cleaning part, installing bases are evenly and fixedly connected to the periphery of the outer side wall of the fixing ring, inserting grooves are formed in the positions, close to the edge of a right opening, of the periphery of the inner wall of each installing base, and rotating grooves are formed in the positions, close to the center, of the periphery of the inner wall of each installing base, a clamping groove is arranged in the right side of the rotating groove, a sealing side wall is arranged on the left side of the installing base, locking screw holes are formed in the edges of the left side and the right side of the inserting hole, the power piece comprises a connecting rod, a hemispherical wind cup is fixedly connected to one end of the connecting rod, and a plurality of clamping blocks are fixedly connected to the peripheral side walls, close to the edges, of the other end of the connecting rod. Through the cleaning brush which is arranged on the cleaning part and is tightly attached to the upper surface of the umbrella skirt, the cleaning brush rotates along with the fixing ring to clean the upper surface ofthe umbrella skirt, and then self-cleaning of the insulator in the using process is achieved.

Description

technical field [0001] The invention relates to the technical field of insulator cleaning for overhead transmission lines, in particular to an insulator with self-cleaning effect for overhead transmission lines. Background technique [0002] An insulator is a special insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for utility poles, and gradually developed in the high-voltage wire connection tower with a lot of disc-shaped insulators hanging at one end. It is to increase the creepage distance. It is usually made of glass or ceramics, called insulators, insulators. It plays the role of supporting conductors and preventing current from returning to the ground in overhead transmission lines. [0003] As one of the important equipment for transmission lines, insulators are responsible for the important task of suspending conductors and insulating towers. The suspension porcelain insulators produc...
