Dual-band ultraviolet video multi-information fusion-based partial discharge monitoring device and detection method

Abstract

The invention proposes a dual-band ultraviolet video multi-information fusion-based partial discharge monitoring device and detection method which can detect partial discharge of power equipment. The dual-band ultraviolet video multi-information fusion-based partial discharge monitoring device of the invention includes a dual-band multi-sensing front-end device, a partial discharge multi-information fusion processing circuit, a monitor / PC, an electric equipment state monitoring system and a warning device, wherein the dual-band multi-sensing front-end device comprises an ultraviolet sensor and a dual-band ultraviolet binocular camera and can not only detect ultraviolet quantitative discharge quantity, but also can acquire videos of two different bands of partial discharge, and therefore, partial discharge multi-information fusion recognition and processing can be facilitated. With the dual-band ultraviolet video multi-information fusion-based partial discharge monitoring device and detection method of the invention adopted, real-time video monitoring can be performed on electrical equipment on site; multi-information fusion identification and warning can be performed on partial discharge; defects of other partial discharge sensors can be eliminated; and a problem of repeated financial investment under a situation in which video monitoring is realized can be solved.

Description

Technical field [0001] The invention patent relates to the technical field of power equipment safety and detection, in particular to a partial discharge monitoring device and detection method based on dual-band ultraviolet video multi-information fusion. Background technique [0002] With the development of digital video processing technology and microprocessor technology, video surveillance and digital image recognition methods and devices have been widely used, researched and applied in more and more industries, with the purpose of improving safety production and industry automation. Among them, in terms of electricity, due to the manufacturing, on-site installation and operation of electrical equipment, it is inevitable that some bad defects will be generated in it. These weak parts are easy to cause discharge under the action of strong electric field, but with the degree of discharge With continuous development, the insulation is further damaged, and the power equipment fails...

AI Technical Summary

Problems solved by technology

However, most of the existing video monitoring systems only have the monitoring function and no recognition function; if there is a recognition function, it is also based on the PC video algorithm to identify specific objects, which cannot meet the needs of partial discharge on-site monitoring and recognition

In addition, this type of partial discharge video detection is based solely on video, which has insufficient accuracy and reliability.
