Embodiment Construction

[0080] figure 1 A conventional modern upwind wind turbine 2 according to the so-called "Danish concept" is illustrated with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and three blades 10 extending radially from the hub 8 , each blade having a blade root 16 closest to the hub and a blade tip 14 furthest from the hub 8 .

[0081] figure 2 A schematic diagram of an example wind turbine blade 10 is shown. The wind turbine blade 10 has the shape of a conventional wind turbine blade having a root end 17 and a tip end 15 and comprising a root region 30 closest to the hub, a profile or airfoil region 34 furthest from the hub, and an airfoil region 34 at the root region 30. and the transition zone 32 between the airfoil zone 34 . The blade 10 comprises a leading edge 18 facing the direction of rotation of the blade 10 when the blade is mounted on the hub and a trailing edge 20 facing in the opposite direction to the l...

Abstract

Disclosed is a support element for a lightning protection system of a wind turbine blade comprising: a first surface configured to face towards the suction side or the pressure side of the wind turbine blade; a second surface opposite the first surface; a root side surface configured to face towards the root of the wind turbine blade; and a tip side surface configured to face towards the tip of the wind turbine blade; wherein the first surface comprises a first receptor base recess configured to receive a first receptor base for coupling with a first receptor of the lightning protection system.

Description

technical field [0001] The present disclosure relates to brackets for supporting lightning protection components such as lightning receptors and / or lightning cables of wind turbine blades. Background technique [0002] As wind turbines and wind turbine blades increase in size, the risk of lightning striking the wind turbine increases. There is therefore an increased interest in providing wind turbines and in particular wind turbine blades with lightning protection measures. [0003] It is known to provide blades for wind turbines with lightning receptors, said lightning receptors inside the blade being electrically connected to a metallic lightning arrester capable of diverting the lightning current Connect to ground. [0004] Wind turbine blades are typically assembled from many components. For example, typical wind turbine blades are manufactured by molding individual shell halves, shear webs, and the like. [0005] Fiber reinforced polymer wind turbine blades and in p...
