A blade root cover segment suitable for fitting to a wind turbine blade to span a gap between the blade and a spinner cover. The blade root cover segment includes a first end and a second end and further includes a curved flange for abutting against a correspondingly curved surface of the wind turbine blade; a cover wall extending radially from the flange; and a tensioning band associated with the flange. The tensioning band includes a first end proximate to the first end of the blade root cover segment and a second end proximate to the second end of the blade root cover segment. The first end and the second end of the tensioning band include connection means for connecting with and applying tension between a like blade root cover segment. A blade root cover and a method of assembling a blade root cover are also provided.

Relating to wind turbine blade root cover

The present invention relates to a lightning current transfer system () adapted for usage in a wind turbine (W) having a hub () that is rotatably supported relative to a generator in a nacelle () and a plurality of blades () that are pivotably connected with the hub, wherein the hub () is covered by a spinner (A). The lightning current transfer system () comprises a blade band (A) mountable to the root of the blade (); a lightning ring () mountable to the spinner (A) facing the nacelle (); a first contact device () mountable to the spinner (A) adapted for providing lightning current transfer from the blade band (A); a connecting device () for connecting the first contact device () with the lightning ring (); and a second contact device (B) mountable to the nacelle () and adapted for providing lightning current transfer from the lightning ring () to ground.

A wind energy converter includes a wind turbine, a wind turbine foundation including a strengthening structure, and a temperature control mechanism for controlling the temperature of one or more areas of the wind turbine. The wind energy converter is characterized in that at least a part of the temperature control mechanism adjoins the strengthening structure. Also contemplated is a wind turbine foundation including a strengthening structure. The wind turbine foundation is characterized in that the foundation includes at least a part of a temperature control mechanism for heat exchanging with one or more areas of a wind turbine and in that at least a part of the temperature control mechanism adjoins the strengthening structure. Even further contemplated is a method for controlling the temperature of one or more areas of a wind turbine and use of a wind turbine foundation.
