The invention provides a nonlinear transmission wire breeze vibration protection device; the nonlinear transmission wire breeze vibration protection device is hung on a power transmission wire and ischaracterized in that the device comprises a sealing device and an electromagnetic damping device (2); the sealing device is of a hollow closed structure and is wrapped outside the electromagnetic damping device (2), so that the interference of the inner magnetic field and the outer magnetic field is prevented; the electromagnetic damping device (2) comprises a horizontal guide pipe (7) and a plurality of crossed guide pipes, and a certain included angle is formed among the crossed guide pipes, and the crossed guide pipes are fixed on the horizontal guide pipe (7) separately. According to thedevice, nonlinear electromagnetic damping can be generated in the vibration of the transmission wire, energy consumption is increased, meanwhile, the applicable vibration range is wider, and vibrationof the transmission wire can be better reduced.
