AI Technical Summary
When modern wind turbine blades are struck by lightning, existing technologies struggle to effectively prevent delamination and arcing around the electrical conductors, and the manufacturing process is complex.
The structure employs a combination of fiber sheath and support elements. The fiber sheath completely surrounds the electrical conductor, while the support elements extend along the length of the blade and are connected to the electrical conductor via finger-like components, forming redundant electrical connections to evenly distribute the current. The support elements are made of conductive fibers such as carbon fiber to enhance structural rigidity.
It effectively prevents conductor delamination and arcing during lightning strikes, improves the structural strength of wind turbine blades and the uniformity of current transmission, and simplifies the manufacturing process.
