Abstract

The invention discloses an automatic detection method for a zero-value insulator in a power transmission line. The method comprises the following steps: acquiring an infrared inspection image and a visible light inspection image; identifying an insulator in the visible light inspection image through target detection, and then cutting the visible light inspection image to obtain an insulator visible light image; segmenting the insulator steel cap in the insulator visible light image by using an image mask; according to the segmented insulator visible light image, segmentation of an insulator steel cap area in the infrared inspection image is realized through feature matching; and judging whether the insulator string has a zero-value insulator or not by calculating the relative temperature difference of each insulator steel cap. According to the method, the zero-value insulator is judged, and the insulator can be accurately and automatically positioned, so that the detection accuracy of the zero-value insulator can be effectively improved.

Description

technical field [0001] The invention relates to an automatic detection method for a zero-value insulator in a transmission line, and belongs to the technical field of insulator detection. Background technique [0002] In power systems, insulators are widely used insulating components in transmission lines, but during operation, they are gradually degraded by factors such as atmospheric pollution, electrical load, and mechanical stress, and eventually form zero-value insulators. The existence of zero-value insulators can easily lead to flashover accidents and lead to grid paralysis, which poses a great threat to the insulation design of the line and the safe operation of the power system. Therefore, it is of great significance to detect whether there are zero-value insulators in the insulator string. Infrared detection technology is based on the difference between the thermal imaging characteristics of zero-value insulators and normal insulators. It has the advantages of reli...
