Lightning protection for wind turbine

Abstract: The wind turbine generator has a mat (10) supporting an electricity generator at its top end, driven by a wind turbine rotor. The rotor blades (14) are each provided with at least one conductor path (17) extending along their length, which are galvanically separated from earth potential during normal operation. A low-ohmic connection is provided between the rotor blade conductor paths and earth in the presence of atmospheric lightning, via discharge paths (23,30,31) an earth line (29), to provide lightning protection.

Transient overvoltages protection element for supply network

Abstract: A transient overvoltage protection device in an arc-control chamber has two electrodes (2) which together form the inclined arcing-horns (6) separated by a divergent airgap (3) and also provide the connection terminals (5) to the supply network.An overvoltage monitoring and spark flashover section comprises a slotted insulator (10) aligned with a transverse hole (7) which collectively ensure a reliable response to transient potentials and initiate movement of the arc roots along the arcing-horn surfaces (8).The insulator (10) and parts of the arc chamber are of inorganic material to exclude carbon/soot contamination and the electrodes (6) are equipped with cooling fins (9) for improved energy rating/arc extinction

Overvoltage protection system and overvoltage protection element for an overvoltage protection system

Abstract: An overvoltage protection system with an overvoltage protection element (1) and an ignition aid which triggers the overvoltage protection element (1), the overvoltage protection element (1) having two main electrodes (2, 3) and an air-breakdown spark gap (4) which acts between the main electrodes (2, 3). An overvoltage protection system having a relatively small and also largely constant operating voltage is implemented by there being an ignition circuit (5) with an ignition voltage output (6) as the ignition aid, the overvoltage protection element (1) having an ignition spark gap (7) which acts between the main electrodes (2, 3) with at least one ignition electrode (8) and the ignition electrode (8) being connected to the ignition voltage output (6) of the ignition circuit (5).

Wind power installation

Abstract: The invention relates to a wind power installation. Modern wind power installations are regularly equipped with a lightning protection system. The aim of the invention is to avoid cited drawbacks and, in particular, to minimize the number of disturbances to the electronics caused by sparkovers occurring on the spark gaps. The invention also relates to a wind power installation comprising a device for continuously discharging electrostatic charge from at least one rotor blade of a wind power installation.

Wind turbine blade with a system for deicing and lightning protection

Abstract: Wind turbine blade comprises a first (1) and a second (2) electric conductor extending in the longitudinal direction of the blade (25), and one or more electric heating elements (4) for heating the surface of the blade. The heating elements (4) are connected to the first and the second electric conductor. At its tip the wind turbine blade (25) is provided with a lightning receptor (5) for catching lightning, and the lightning receptor (5) is electrically connected to a third (3) conductor earthed so as to be able to carry the current from a stroke of lightning to the earth. The first and the second conductor are connected to the lightning receptor through spark gaps adjacent said lightning receptor and connected to earth through spark gaps adjacent the blade root.

Lightning protection for wind turbine blade

Abstract: A wind turbine blade with a lightning conductor, where said lightning conductor is formed by one or more oblong strips (1, 2, 3) of carbon fibre-reinforced plastics preferably forming part of the wind turbine blade. In this manner the oblong strips (1, 2, 3) of carbon fibre-reinforced plastics both reinforce the blade and divert the lightning.

A method of lightning-proofing a blade for a wind-energy plant

Abstract: The invention relates to a method of lightning-proofing a blade (1) on a wind-energy plant, which blade comprises a blade shell (2) configured essentially as a fibre-reinforced laminate, which laminate comprises electrically conductive fibres, wherein the blade comprises at least one lightning arrester (9) configured for conducting lightning current, including preferably to ground. The method comprises that the electrically conductive fibres are connected to each other, and that at least one metallic receptor (4, 24, 25) is arranged for capturing lightning current at or in proximity of the external face of the blade; and that the receptor and the fibres are connected to the lightning arrester for equalising the difference in potential between the lightning arrester and the electrically conductive fibres. When the electrically conductive fibres are connected to each other, the fibres will cooperate on the conduction of a possible lightning current to prevent the current from running in individual fibres. Simultaneously the metallic receptor will serve as the primary lightning capturing device and reduce the risk of lightning striking the laminate. The receptor being connected to the lightning arrester, the current will predominately be conducted to ground, while the risk of transfer to the laminate is minimised in that a possible difference in potential between fibres and lightning arrester has been equalised.
