Embodiment Construction

[0048] exist figure 1 A wind turbine 1 with a tower 3 and a nacelle 2 mounted rotatably on the tower 3 is shown in FIG. A drive system is provided in the nacelle 2 , comprising a rotor shaft 35 mounted rotatably on a machine frame 41 , which is optionally connected via a transmission 36 to a generator 37 . Arranged on the rotor shaft 35 is a rotor 38 which in turn comprises a hub 39 and at least one rotor blade 40 .

[0049] A number of conductive components are installed on the nacelle 2, such as handrails 6, fixing rings, lightning catchers 5, aviation indicator lights 7, anemometers 8 and outlets 9. In order not to cause injury to persons due to potential differences between the individual conductive components 5 , 6 , 7 , 8 , 9 , a potential equalization between these components 5 , 6 , 7 , 8 , 9 must be ensured. Furthermore, in order to dissipate the lightning current in the event of a lightning strike, the lightning arrester 5 must be connected to the ground 29 . The ...

Abstract

The invention relates to a wind turbine comprising an electromagnetically shielding nacelle cover, to a nacelle cover having an electromagnetically shielding effect, to an element for a nacelle cover that is composed of a plurality of elements, and to a method for producing such an element for a nacelle cover of a wind turbine. The aim of the invention is to provide a nacelle cover for a wind turbine which offers a solution to the problems mentioned in the prior art. Said aim is achieved by a nacelle cover for a nacelle of a wind turbine according to claim 1. The nacelle cover is formed of a composite material which can comprise, for example, an outer layer made of a fiber material or fiber mats such as glass fiber mats and an interposed foam layer. A conductor layer, for example a mesh, a woven fabric or a coating made of conductive material is integrated between the fiber layers of the composite material to provide electromagnetic shielding of the nacelle. The conductor layer is also connected, or can be connected, directly or indirectly, to at least one conductive construction that is fitted on the outside of the nacelle cover.

Description

technical field [0001] The invention relates to a wind turbine with an electromagnetic shielding nacelle casing, an electromagnetic shielding nacelle casing, an element for a nacelle casing consisting of several elements and a method for producing such Method for elements of a nacelle enclosure for a wind turbine. Background technique [0002] Electromagnetic shielding is necessary in order to reduce field-related interference from wireless systems, lightning and other sources of interference to electrical and electronic systems in the nacelle. Electromagnetic shielding is used on the one hand to protect the sensitive technology of the switching system involved and, on the other hand, to protect persons from injury due to possible leakage currents or electrical discharges. [0003] An important field of application for such measures is the nacelle of a wind turbine, since here sensitive technical systems accessible to maintenance personnel are arranged in the narrowest of s...
