摘要： The invention relates to a wind turbine rotor blade comprising a blade tip and a lightning protection system. The blade includes at least one metallic lightning receptor at the surface of the bladein proximity of the distal end of the blade tip. The blade comprises a blade shell configured partly by a fibre-reinforced laminate, and the blade also comprises an electrically down-conducting element in the form of a metallic mesh. The electrically down-conducting element extends only to a certain distance from the distal end of the tip of the blade, said distance being larger than a distance between the position of the lightning receptor and the distal end of the tip of the blade. It is hereby ensured that a stroke of lightning will strike the receptor more likely than the electrically down-conducting element.

摘要： The present invention proposes a lightning protection device of a windmill blade, comprising a tip receptor assembly having receptors which are mounted, in particular to, the tip end part of the blade where the blade profile becomes smaller, and having a simple structure so as to be readily assembled, and an intermediate receptor assembly having a receptor which is set at the outer surface of the blade so as to exhibit an effective countermeasure against increasing of the air pressure in the blade upon a lightning striking upon the blade, a lightening current being discharged to the ground from the receptors through connection equipment such as lead wires laid through the inside of the blade the windmill body and bypass brushes, characterized in that a base plate made of an electrically conductive material and connected thereto with the lead wires is embedded in the blade, and the receptors are secured and supported to the base plate, being exposed at the outer surface of the blade. Further, the present invention also proposes a method of assembling the lightning protection device.

摘要： The invention relates to a lightning protection system for a wind turbine blade, where the blade is a shell body made of a composite material and comprises a root area and a tip end. The lightning protection system comprises at least one lightning receptor arranged freely accessible in or on the shell unit surface on or in the immediate vicinity of the tip of the blade, and a lightning conductor made of electrically conductive material extending within the shell body along substantially the entire longitudinal direction of the blade. The lightning receptor and the lightning conductor are electrically connected by means of a connection area. The lightning conductor in its entire longitudinal direction as well as the connection area between the lightning conductor and the lightning receptor are electrically insulated in order to prevent lightning striking through the surface of the blade.

According to the invention a first end (4) of the lightning transmission element (1) is positioned opposite a metal strip (18) that is disposed at the root of each blade (10) of the wind generator at a first distance which enables a flashover of incident lightning at a point on a blade (10) of the wind generator, while a second end (3) thereof is positioned opposite a gutter (12) of a nacelle (13) of the wind generator at a second distance which enables a lightning flashover. The lightning is conveyed from the point on the blade (10) at which it is incident thereon to the earth through a series of conduction means including the lightning transmission elements (1), said means preventing the lightning from striking the sensitive parts of the wind generator.

摘要： Lightning protection system of wind turbine blades formed by various connections arranged on carbon fibre laminates (2) of the blade (1), equipotentialising the surface of the airfoils (4) of the beam (10) via derivations from a main cable (6) using the respective auxiliary cables (5). The auxiliary cables are connected to metal plates (3) which make the direct connection with the carbon fibre laminates (2) and are positioned during the blade (1) laminating and curing process, or they are connected to metal pins, preferably cone shaped, which pass through the hybrid laminate.
Around the connections a nanocomposite based conductive resin (11) is arranged.
In the case of a hybrid laminate with layers of carbon fibre and layers of fibre glass, the equipotential state of the different layers is achieved using windows, discontinuities or open spaces in the fibreglass layers.

A spark gap ( 15 ) is provided between the lightning down-conductor and the rotor hub, said spark gap ( 15 ) being adapted to conduct a lightning current passing through the lightning down-conductor. A sliding contact connection ( 7, 12 ) is provided parallel to the spark gap ( 15 ) between the lightning down-conductor ( 6 ) and the rotor hub ( 3 ), said sliding contact connection ensuring electrical contact between said lightening down-conductor ( 6 ) and said rotor hub ( 3 ) irrespective of the pitch angle of the blade.
