Rapid nondestructive transformer coil material detection method

The invention relates to the technical field of power transformer detection equipment, in particular to a rapid lossless transformer coil material detection method, which comprises the following steps: S0, connecting a transformer A-phase winding with two test wires through a wire inlet end copper bar and a wire outlet end copper bar, and electrically connecting the two test wires with a control device; s1, a heating module is fixed on a wire inlet end copper bar; s2, the heating module is controlled to heat to the temperature t0; s3, copper bars at the wire inlet ends of the B-phase winding and the C-phase winding of the transformer are heated to the temperature t0 in the same mode; s4, the control device preliminarily judges the material condition of the transformer; and S5, the control device accurately judges the material condition of the three-phase winding of the transformer. According to the method, the conducting rods at the two ends of the winding do not need to be heated and kept at the same tempera
