Transformer winding deformation type and degree detection method based on ribbon fiber

The invention discloses a method for detecting the deformation type and degree of a transformer winding based on ribbon optical fibers. The ribbon optical fibers to be detected are arranged on the upper side of the transformer winding according to the specific composition of the transformer winding to be detected; using a distributed optical fiber strain sensing system to measure strain vectors of the N fiber cores; according to the obtained calculation strain value of each fiber core, calculating to obtain a corresponding calculation strain vector; according to the method, a traditional distributed optical fiber sensing method is improved, the ribbon optical fibers are arranged on the transformer winding, the deformation type detection and degree of the transformer winding are effectively detected, and the axial strain and the radial strain are detected in a distinguished mode, so that the detection accuracy of the transformer winding is improved, and the detection accuracy of the transformer winding is impr
