Abstract

The embodiment of the invention discloses a transformer winding detection method and device, electronic equipment and a storage medium. The transformer winding detection method specifically comprises the following steps: obtaining a to-be-detected winding target element curve of a to-be-detected transformer; performing curve matching on the target element curve of the winding to be detected and a target element curve of a reference winding to obtain a curve matching result of the target element curve of the winding to be detected; wherein the reference winding target element curve is a winding target element curve of a non-to-be-measured transformer; and determining a winding deformation detection result of the to-be-detected transformer according to the curve matching result. According to the technical scheme provided by the embodiment of the invention, the deformation of the transformer winding can be accurately detected, so that the accuracy and reliability of a deformation detection result of the transformer winding are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of transformer detection, and in particular to a transformer winding detection method, device, electronic equipment and storage medium. Background technique [0002] The power transformer is one of the important electrical equipment in the power system. The normal and stable operation of the transformer is of great significance to the safe production and reliability of the power system. With the increasing capacity of the power grid, the losses and impacts caused by transformer failures are becoming more and more serious. Among them, winding deformation is one of the most important fault types of transformers, and winding deformation may be caused by various force majeure factors such as human misoperation, external force and other natural disasters during transportation, installation and operation of transformers. Therefore, it is necessary to accurately detect the deformation deg...
