Wind turbine blade having a corrosion protection structure, and wind turbine having the same

摘要

The present invention relates to a wind turbine component, having a connecting portion for connecting the wind turbine component to another turbine component and at least part of the connecting portion is formed of a first type of metal, characterized in that: the connecting portion is further provided with an additional part formed of a second type of metal which is connected to the metallic part of the connecting portion; and the second type of metal is more active than the first type of metal, whereby the additional part forms a sacrificial anode. The present invention further relates to a wind turbine having the above component.

主权项

1. A wind turbine blade having a connecting portion at a root section for connecting the wind turbine blade to a hub, the root section provided with a plurality of inserts extending into the wind turbine blade spaced around the root section by which the connection can be made between the wind turbine blade and the hub, the plurality of inserts having exposed end faces and being formed of a first type of metal, wherein additional parts of a second type of metal are connected to the plurality of inserts, the second type of metal being more electrochemically active than the first type of metal, whereby the additional parts form a sacrificial anode.
