Problems solved by technology

[0006] Although monitoring leakage current is a conventional method to study the insulation state of insulators, engineering practice has shown that monitoring leakage current alone has poor universality, and cannot directly reflect the creepage development process of insulators, which brings errors to the detection of pollution flashover of transmission line insulators. Therefore, it is necessary to improve the existing technology

Abstract

The invention discloses an automatic visual observation system and method for pollution flashover of transmission line insulators. A video is made for the leakage current at a target insulator and thepollution flashover event process image of the insulator. Remote view of the pollution state of the surface of a high-voltage line insulator, pollution flashover warning, and video visualization of the evolution process are realized. Therefore, the pollution flashover detection result of transmission line insulators can be obtained more accurately, and the detection quality of pollution flashoverof transmission line insulators is improved.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of transmission line insulators, and in particular relates to an automatic and visual observation system and method for pollution flashover of transmission line insulators. Background technique [0002] Insulators are one of the key components of overhead transmission lines, and their performance directly affects the safe operation of the entire transmission line. [0003] With the deterioration of the environment and the aggravation of pollution, grid pollution flashover accidents gradually involve a wide range, seriously threatening the safe operation of power transmission equipment. In the atmospheric environment, the operating insulators are affected by factors such as natural dust and industrial emissions, and dirt is gradually deposited on the surface. Flashovers cause accidents. According to statistics, in the total number of accidents in the power system, pollution flashover a...
