Abstract

The lightning protection system has a connection is provided from the rotor blade point for the earth connection housing. The connection between the rotor blade point is provided with the retainer blade tip. The connection between the blade tip and the blade tip insertion cylinder exists through a cable.

Description

Die Erfindung betrifft einen Blitzschutzsystem für Rotorblätter von Windkraftanlagen.The The invention relates to a lightning protection system for rotor blades of wind turbines.

Die Blitzschlaggefährdung von Bauwerken wächst in etwa quadratisch mit der Bauwerkshöhe, schon für kleinere Windenergieanlagen ist statistisch mit einem Blitzschlag innerhalb wenige Jahre zu rechnen Im Einzelfall verursachen Blitze aber Schwerwiegende Schäden bis hin zum total Ausfall und haben überdurchschnittlich hohe Reparaturkosten und Ausfallzeiten zur Folge Windenergieanlagen der Typ Nordex N27–N29 haben zurzeit keinen Blitzschutz an den Rotorblätter.The Lightning hazard of buildings grows roughly square with the height of the structure, even for smaller wind turbines statistically a lightning strike can be expected within a few years In individual cases, however, lightning strikes cause serious damage to total failure and have above average high repair costs and downtime result wind turbines of the Type Nordex N27-N29 currently have no lightning protection on the rotor blades.

Der Erfindung liegt daher die Aufgabe zugrunde, Ein Blitzschutzsystem herzustellen die der Blitzeinschlag ableitet.Of the The invention is therefore based on the object A lightning protection system the lightning strike derives.
