Abstract

The invention provides a partial discharge detection method, device, system and equipment, and a readable storage medium. The partial discharge detection method comprises the steps of obtaining a to-be-detected region image; denoising the to-be-detected region image through a context aggregation network model to obtain a denoised image; judging whether partial discharge exists in the to-be-detected region or not according to the denoised image; and if partial discharge exists in the to-be-detected region, identifying a discharge area and a severity degree of the partial discharge of the to-be-detected region through an acceleration area convolutional neural network model according to the denoised image. The partial discharge detection method provided by the invention can improve the efficiency and accuracy of partial discharge detection.

Description

technical field [0001] The present application relates to the technical field of substation operation and maintenance, and in particular to a partial discharge detection method, device, system, equipment and readable storage medium. Background technique [0002] With the development of the economy and the improvement of the quality of life, the demand for electricity consumption by residents and factories is also increasing. The normal and stable operation of the substation equipment is particularly important, because the failure of the substation equipment will have a negative impact on the electricity consumption of residents and factories. greater impact. [0003] The faults of substation equipment are mainly divided into three categories: mechanical faults, heating faults and insulation faults. Insulation fault is the most common type of fault, and partial discharge fault is one of the common faults in insulation faults. Although partial discharges do not immediately b...
