Dry-type transformer winding coil material eddy current detection method and device

The invention relates to a dry-type transformer winding coil material eddy current detection method and device, an eddy current analyzer is connected with an eddy current detection probe, and the eddy current detection probe is used for receiving an impedance signal of an induced magnetic field and transmitting the impedance signal back to the eddy current analyzer; the winding reference block comprises a copper winding layer and a thickness-adjustable non-metal layer covering the outer side of the copper winding layer, and the structure of the copper winding layer is the same as that of a to-be-detected dry-type transformer winding; the aluminum winding reference block and the copper winding reference block have the same structure, and the difference is that the aluminum winding layer replaces the copper winding layer; the method is suitable for acceptance inspection of dry-type transformer winding materials, and the sensitivity of the method can effectively judge the winding coil materials.
