Problems solved by technology

The used fluid (air) must be cleaned so that it does not generate dirt and particles which may limit the cooling quality or possibly cause damage to the generator internals
Contaminated fluid in particular can cause electronic failure and loss of production power when the cooled fluid (air) is inserted into the generator

Embodiment Construction

[0054] The illustration in the figure is schematic. It should be noted that in different figures, similar or identical elements or features are provided with the same reference signs or with reference signs that differ from the corresponding reference signs only within the first digit. In order to avoid unnecessary repetition, elements or features that have already been explained with respect to the previously described embodiments will not be described in detail later in this specification.

[0055] In addition, spatially relative terms, such as "front" and "rear", "upper" and "lower", "left" and "right", etc., are used to describe the relationship of one element to another element(s), as shown in Fig. shown in . Thus, spatially relative terms may apply to orientations in use that differ from the orientation depicted in the figures. Obviously, all such spatially relative terms refer to the orientations shown in the drawings for ease of description only, and are not necessar...

Abstract

It is described a filter device configured for providing air for a generator of a wind turbine. The filter device comprises a housing comprising a filter, at least one attaching element configured forattaching the housing to a drive end side of the generator, such that the air is guidable through the filter into the generator. Further, a wind turbine is described which comprises a filter device for providing air for a generator of the wind turbine. Furthermore, a method for arranging a filter device configured for providing air for a generator of a wind turbine is described.

Description

technical field [0001] The invention relates to the field of wind turbines equipped with a generator and a filter arrangement configured for supplying air to the generator of the wind turbine. In particular, the invention relates to a filter arrangement configured for supplying air to a generator of a wind turbine, wherein air is provided into the generator from outside the wind turbine through the filter arrangement. Furthermore, the invention relates to a method for arranging a filter arrangement configured for supplying air to a generator of a wind turbine. Background technique [0002] The generators used in many wind turbine types must work with high precision. In operation, they must maintain stable working performance. During operation, generators generate heat due to filtration, which must be limited to prevent damage to the generator and ensure consistent performance. The generator is thus cooled by a fluid, in particular air, which is led into the generator for ...
