Description

Technical Field

[0001] The present invention relates to the field of electric power facilities, and in particular to an insulator management system for electric power equipment. Background Art

[0002] The main functions of insulators are to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are specified.

[0003] For example, under the specified operating voltage, lightning overvoltage, and internal overvoltage, there should be no breakdown or surface flashover; no damage or destruction under specified long-term and short-term mechanical loads; no significant degradation after long-term operation under specified mechanical and electrical loads and various environmental conditions; and no significant corona discharge from insulator fittings under operating voltages to prevent interference with radio or television reception. Because insulators are widely used, their connecting fittings are also required to be interchangeable.

[0004] In addition, the technical standards for insulators also require that insulators be subjected to various electrical, mechanical, physical and environmental condition changes tests according to different models and usage conditions to verify their performance and quality.

[0005] In the prior art, the environment in which power facilities are located is relatively complex. For example, as trees near insulators continue to grow, the position of the insulators may also change during long-term use. If the insulators are too close to the trees, it will pose a huge hidden danger to the safety and stability of the entire power facility where the insulators are located. Summary of the Invention

[0009] a customized filtering device, disposed in the flight inspection device and connected to the aerial photography actuator, for performing maximum filtering on the received image to obtain and output a corresponding maximum filtered image;

[0010] a data sharpening device connected to the customized filtering device, configured to perform a spatial differential sharpening process on the received maximum filtered image to obtain and output a corresponding data sharpened image;

[0013] The abnormality reporting mechanism is connected to the scene detection mechanism and is used to wirelessly transmit the received tree occlusion detection signal or other object occlusion detection signal to a remote overhead line maintenance server.

[0014] The power equipment insulator management system of the present invention has a compact structure and intelligent operation. It uses a targeted visual analysis mechanism to determine the stereoscopic visual model corresponding to the insulator and estimates the volume of the insulator based on the stereoscopic visual model and the imaging focal length of the imaging lens, thereby providing reference information on whether the insulator is obscured.
