Column type porcelain insulator with protection function

Abstract

The invention discloses a column type porcelain insulator with a protection function, which comprises a wire connecting piece, a switching sleeve, an arc striking rod, an insulator main body, a wind-rotating cleaning piece, a base, a metal inner core and an arc extinguishing ball, and is characterized in that the bottom of the wire connecting piece is fixedly mounted on the top of the insulator main body through the switching sleeve; and the interior of the insulator main body is fixedly plugged with the top of the metal inner core. According to the column type porcelain insulator with the protection function, outdoor natural wind is utilized to enable the driving fan blades of the wind-rotating cleaning piece to be pushed, so that the bent rod piece and the wiping strips on the inner side of the bent rod piece are driven to perform wiping and cleaning work on the outer side of the insulator main body, dust and ice and snow adhered to the outer wall of the insulator main body are scraped off, and thus the purpose of protecting the outer wall of the insulator main body is achieved. Therefore, the outer wall of the insulator main body is kept clean, and the problem that leakage current on the surface of the insulator is increased due to smudginess, so that an insulator flashover accident also occurs under working voltage is solved.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a cylindrical porcelain insulator with a protective function. Background technique [0002] Insulators are devices installed between conductors of different potentials or between conductors and ground potential components, which can withstand voltage and mechanical stress. It is a special insulation 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 when a lot of disc-shaped insulators were hung at one end of a high-voltage wire connection tower, which was used to increase the creepage distance, usually made of glass or ceramics, called insulators. [0003] In the prior art, such as "a light-weight and high-strength column-type porcelain insulator" of Chinese patent number: CN 109754961 A, it includes a body, the bottom end of the body is provided with steel feet, a...

Problems solved by technology

[0004] However, in the prior art, insulators have been in the outdoor environment for a long time, and the dirty substances adhering to the surface of the insulator generally have a certain degree of conductivity and hygroscopicity. Insulation level, thereby increasing the surface leakage current of the insulator, so that the accident of insulator flashover or wooden pole burning may also occur under the working voltage
