Summary: | Embodiments of the present invention provide a contactor, a wind power generator, and a contactor control method. The contactor is applied to the wind power generator, and comprises a rotating shaft and at least one set of contactor units, wherein each contactor unit comprises a voltage regulating component, an electrical contact and a conductive ring; the conductive ring is sleeved on the rotating shaft; the electrical contact is opposite to the conductive ring; the voltage regulating component is connected with the electrical contact and is used for adjusting the contact pressure between theelectrical contact and the conductive ring according to each working state of the wind power generator. The contactor can reduce the wear amount of the electrical contact when performing the yaw action, and reduces the generated heat of the electrical contact when the wind turbine is in a normal working state and performs the yaw action, thereby effectively prolonging the service life of the electrical contact, reducing |
