Abstract:
1. A transmission device for a wind turbine for transferring electrostatic energy between a rotatable rotary device and a grounding device that cannot be rotated with respect to the rotary device, the transmission device comprising a holder, a sliding contact device with pressing means, and at least one electrode with adjusting means to transmit lightning current, wherein a spark gap with a sparking distance S is formable between the at least one electrode and a ring electrode, and wherein the sliding contact device permanently acts upon the ring electrode, wherein the holder is arranged in a non-rotatable manner relative to the grounding device or in a manner of being rotationally fixed on the rotary device, the transmission device comprises a tracking device with supporting means, wherein the tracking device is effectively arranged between the ring electrode and the at least one electrode, wherein the ring electrode or the at least one electrode is connected to the rotary device in a manner of being rotationally fixed, wherein the at least one electrode is arranged in a movable manner relative to the holder via the tracking device, and wherein the at least one electrode is supported relative to at least one of the rotary device and the ring electrode by the supporting means in such a way that the sparking distance S does not fall below a minimal dimension.
