  • Patent number: 11629689
    Abstract: The polyurethane material is prepared from a polyol, butanediol, and an isocyanate. The protective cover is adapted to be attached along at least a part of a longitudinal edge of the wind turbine blade by adhesion of an inside of the protective cover to a surface of the longitudinal edge of the wind turbine blade. The protective cover is elongated in a longitudinal direction and has an at least substantially U-formed cross-section. The protective cover includes a central cover section extending in the longitudinal direction and two peripheral cover sections extending in the longitudinal direction at either side of the central cover section, respectively. The central cover section has a minimum thickness of at least 1 millimetre, and each peripheral cover section has a thickness decreasing from a maximum thickness of at least 1 millimetre to a minimum thickness of less than ½ millimetre.

  • Patent number: 11536252
    Abstract: The present invention relates to conductor connection system for a wind turbine lightning protection system adapted to protect a wind turbine blade from lightning strikes. The lightning protection system comprises a down conductor cable adapted to extend in a longitudinal direction of the wind turbine blade and arranged for connection to the root end of the wind turbine blade, and comprises a number of lightning receptors electrically connected to and distributed along the length of the down conductor cable. The down conductor connection system comprises a modular down conductor cable having a first and second down conductor cable part, and at least one down conductor connector arranged between and connected to the ends of the down conductor cable parts. The down conductor connector comprises first and second terminals, connected to an end of each down conductor part, respectively, where the first and second terminals are adapted for mutual connection.

  • Patent number: 10907618
    Abstract: A wind turbine blade includes a protective cover attached along the blade by a layer of adhesive. The adhesive is a general purpose adhesive, and the adhesive forms a joint or sealing between an outer edge of the cover section of the blade and the surface of the blade so that the outer edge is covered by the adhesive and so that the joint forms an oblique surface from the outer edge to the surface of the blade. The joint has a first height at the outer edge and a second height at the position where it ends at the surface of the blade. The second height is smaller than the first height and smaller than 0.2 millimetres, and the joint is integrally formed with the layer of adhesive.

  • Patent number: 10612526
    Abstract: A fully insulated tip unit (1) for a lightning protection system for a wind turbine blade (2) is disclosed, comprising an electrically conducting tip (3), which tip consists of an external part (4) and an internal part (5), at least one side receptor base (6), an internal tip unit conductor (8), an insulated electric cable (9) for forming the outermost part of a down conductor (10), and a connection element (12) for establishing electrical connection between the insulated electric cable and the other conducting parts of the tip unit, wherein the internal part of the tip, the side receptor base(s), the internal tip conductor, the connection element and one end of the insulated electric cable are all embedded by casting in an insulating material (13) leaving only the external part of the tip and the other end of the insulated electric cable uncovered by the insulating material. Furthermore, a wind turbine blade comprising such a tip unit is disclosed.

  • Patent number: 10288044
    Abstract: A receptor assembly (1; 5) for a lightning protection system for a wind turbine blade (2) is disclosed, comprising electrically conducting current carriers (6; 19) and mounting bolts (9) and/or threaded rods (20), wherein each of the current carriers is a metallic part arranged and dimensioned to surround at least a part of a mounting bolt or a threaded rod without being in electrical contact with the mounting bolt or threaded rod, at least a part of the external surface at one end of each current carrier is arranged to be a contact surface (10) for mechanical and electrical contact to a receptor base (3; 16) in such a way that, in the case of a lightning impact on the receptor, the lightning current passes through the one or more current carriers rather than through the one or more mounting bolts and/or threaded rods on its way through the receptor.
