Abstract

Provided is a filter device configured for providing air for a generator of a wind turbine. The filter device includes a housing including a filter, at least one attaching element configured for attaching 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 provided which includes 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 also provided.

Claims

1. A filter device configured for providing air for a generator of a wind turbine, the filter device comprising:

a housing comprising a filter; and

at least one attaching element configured for attaching the housing to a drive end side of the generator, such that the air is guidable through the filter into the generator.

2. The filter device according to claim 1, wherein the at least one attaching element is configured for detachably attaching the housing to the drive end side.

3. The filter device according to claim 1, wherein the at least one attaching element is a magnet element.

4. The filter device according to claim 1, further comprising:

an adapter element comprising the at least one attaching element,

wherein the adapter element has a first side which is attached to the housing,

wherein the adapter element has a second side which is attachable to the wind turbine by the attaching element,

wherein the first side and the second side oppose each other,

wherein the adapter element comprises an opening extending from the first side to the second side and configured for guiding air from the filter into the generator.

5. The filter device according to claim 1, further comprising:

a mesh coupled to the housing, wherein the mesh is configured for providing an electromagnetic field (EMF) shielding for the generator.

6. The filter device according to claim 4,

wherein the mesh is arranged at the adapter element, and is configured for covering the opening of the adapter element.

7. The filter device according to claim 4, further comprising:

a sealing element,

wherein the sealing element is arranged at the second side of the adapter element,

wherein the sealing element is configured for being arranged between the adapter element and the generator, such that a fluid connection between the filter and the generator is sealed.

8. The filter device according to claim 4, further comprising:

fastening elements for fastening the housing to the adapter element.

9. The filter device according to claim 4, wherein the at least one attaching element further comprises at least one of the group consisting of a snap catch, a clamp, a bolt, magnet, and a spring catch.

10. A wind turbine comprising:

a filter device according to claim 1, and

a generator,

wherein the filter device is attached to a drive end side of the generator of the wind turbine.

11. The wind turbine according to claim 10, wherein the drive end side of the generator is formed as an axially outermost part of the generator.

12. The wind turbine according to claim 10, wherein the wind turbine comprises a plurality of filter devices attached spaced apart from each other to the drive end side of the generator.

13. The wind turbine according to claim 10, comprising a spinner, wherein the filter device is arranged between the drive end side of the generator and the spinner.

14. The wind turbine according to claim 10, wherein the drive end side of the generator comprises a further opening configured for receiving the adapter element of the filter device,

wherein the opening of the adapter element and the further opening of the drive end side of the generator are forming an air channel for guiding air into the generator.

15. A method for arranging a filter device configured for providing air for a generator of a wind turbine, the method comprising:

attaching a housing of the filter device by at least one attaching element to a drive end side of a generator of the wind turbine, such that the air is guidable through the filter device into the generator.
