The embodiment of the invention provides a conductive ring and a wind power generator set. The conductive ring comprises a fixed part and a rotation part, wherein the rotation part can rotate relativeto the fixed part, conductive rails are arranged on the fixed part, the conductive rails and the rotation part are coaxially arranged, the conductive rails are insulated to one another, first wiringends are arranged on the fixed part, are in one-to-one correspondence to the conductive rails and are electrically connected with the conductive rails, second wiring ends are arranged on the rotationpart and are in one-to-one correspondence to the conductive rails, two or more than two rolling bodies are arranged on each conductive rail, the rolling bodies are conductors, and the second wiring ends are electrically connected with the corresponding conductive rails via the rolling bodies. When the conductive ring provided by the invention is used for the wind power generator set, a cable between a cabin and a tower cylinder is prevented from being twisted during the process of cabinet yawing, so that the technical characteristic requirement of a main cable can be reduced, high twisting resistance and high wear resistance of the cable are not needed, and the cable cost is reduced.
