An Insulator Detection Method Based on Infrared and Ultraviolet Imaging

Abstract

The invention discloses an insulator detection method based on infrared and ultraviolet imaging. An infrared ultraviolet imaging comprehensive detection method is adopted, and advantages of all kinds of deteriorated insulator detection methods are combined, so based on the infrared imaging method, mistaken and leaked detection occurring in use of the infrared imaging method or the ultraviolet imaging method can be avoided. According to the invention, by use of infrared and ultraviolet double monitoring and related quantitative adjustment method, probability of the mistaken and leaked detection can be reduced, detection efficiency is improved, the detection period is increased, hidden safety hazards in the deteriorated insulators are reduced, and hidden dangers in power transmission line inspection imposed by mistaken and leaked detection are avoided.

Description

technical field [0001] The invention relates to a testing device for electrical properties, in particular to an insulator detection method based on infrared and ultraviolet imaging. Background technique [0002] At present, insulators are widely used in transmission lines, and their operating environment is outdoor transmission lines. The traditional detection method must be detected by climbing a pole, which requires a lot of manpower and material resources, and its accuracy is affected by the environment, manual adjustment of the spark gap distance and work. Factors such as the experience of the personnel have a great influence. Even if the inspection is carried out once a year, there will still be a considerable number of defective insulators still running on the line, which will become a hidden danger to the safe operation of the line. In addition, in recent years, environmental pollution has increased, making the surface of insulators easily covered with dirt. Surface ...

Problems solved by technology

The ultraviolet imager converts the optical signal into an electrical signal by receiving the ultraviolet light signal generated by the discharge. The ultraviolet image is also amplified and then fused with the visible light image to obtain the final device discharge image that can locate the discharge point. It has its own limitations. The infrared imager is not sensitive to weak discharge or the detection of early defects of the equipment. The ultraviolet imaging method cannot detect the internal defects of the equipment or the situation that the insulator does not discharge due to dry pollution defects, etc.
