Zusammenfassung:The invention relates to the technical field of dry-type distribution transformer winding material detection, in particular to a 10kV dry-type distribution transformer low-voltage side winding material nondestructive testing method based on eddy current. The detection method comprises the following steps: obtaining a plurality of simulated low-voltage side windings according to different materials of conductors, different thicknesses of the conductors, different superficial areas of the conductors, different thicknesses of insulating layers and different turns of the windings; respectively detecting the electric conductivity of each simulation low-voltage side winding to obtain a plurality of simulation electric conductivities; detecting the conductivity of the to-be-detected dry-type distribution transformer low-voltage side winding to obtain the actually measured conductivity; and comparing the actually measured conductivity with each simulated conductivity, wherein the conductor material in the simulated l
