Abstract

The embodiment of the invention discloses a transformer ground oil stain detection method, device and equipment and a storage medium, and the method comprises the steps: determining a target feature region of a to-be-detected picture based on a region detection model, and cutting out the target feature region, wherein the to-be-detected picture is the shot picture of the ground near the transformer; performing HSV space conversion on the cut target feature region to obtain a converted HSV color map; and detecting the brightness features of the HSV color map based on the brightness feature detection model so as to detect whether the transformer has the ground oil stain or not. According to the transformer ground oil stain detection method, device and equipment and the storage medium provided by the embodiment of the invention, the accuracy and rapidity of transformer ground oil stain detection can be improved.

Description

technical field [0001] The embodiments of the present invention relate to oil pollution detection technology, in particular to a method, device, equipment and storage medium for detecting oil pollution on the ground of a transformer. Background technique [0002] In the field of power systems, transformers are one of the most important equipment among all kinds of electrical equipment in substations. As a common fault, oil leakage not only reduces the service life of transformers, but also seriously affects the safe operation of power systems. One of the important signs of transformer oil leakage. Therefore, for the safe operation of the power grid and to reduce economic losses, it is necessary to detect whether there is ground oil pollution on the transformer in time. [0003] At present, most of the existing methods for detecting oil pollution on the ground of transformers use manual detection to detect whether there is oil pollution on the ground of transformers. The det...
