Abstract

A box-shaped electric control cabinet is provided which can be closed by a cover and which is used to receive electric components and devices for a blade angle adjustment drive (pitch drive) of a wind energy power plant, by means of which one or more rotor blades of the plant can be rotated about the blade axis. The control cabinet includes at least two cabinet segments, and specific electric components and devices are associated with respectively each module according to its function. The cabinet segments can be associated with and/or assigned to respectively different electric components and devices, with which, combined as a part function, different total functions and/or embodiment forms of the control cabinet can be produced or are producible.

Claims

1-24. -24. (canceled)

25. A box-shaped electrical switchgear cabinet sealed with a cover for accommodating electrical components and equipment for a blade angle adjustment drive for rotatbly position at least one rotor blade of the wind turbine about a blade axis, the switchgear cabinet comprising:

a plurality of cabinet segments assembled to form a the switchgear cabinet;

a first set of electrical components and equipment functionally assigned to a first cabinet segment; and

a second set of electrical components and equipment functionally assigned to a second cabinet segment;

wherein the first set of electrical components and equipment combined as a subfunction which is different from a subfunction of the second set of electrical components and equipment such that different overall functions of the switchgear cabinet can be implemented.

26. The switchgear cabinet according to claim 25, wherein each of the first and second cabinet segments comprise a cabinet fabricated from a material selected from the group consisting of metal, stainless steel, powder-coated steel, plastics or combinations thereof.

27. The switchgear cabinet according to claim 25, wherein the plurality of cabinet segments are arranged laterally to form a box-shaped switchgear cabinet and traverse thereto such that the cabinet segments form a further box-shaped switchgear cabinet with different functions.

28. A switchgear cabinet according to claim 25, wherein each segment has an individual cover.

29. The switchgear cabinet according to claim 25, wherein the plurality of segments are covered by a common cover.

30. The switchgear cabinet according to claim 25, wherein the switchgear cabinet further comprises a third cabinet segment, said plurality of cabinet segments are adjacently arranged and covered by a cover.

31. The switchgear cabinet according to claim 25, wherein each of the plurality of cabinet segments are assignable to a spatial position inside the switchgear cabinet.

32. The switchgear cabinet according to claim 25, wherein the plurlaity of segments are arranged independent of their spatial position inside the switchgear cabinet.

33. The switchgear cabinet according to claim 25, wherein each of the plurality of cabinet segment comprises a first end cap and a second end cap, a first and second outer segment and at least central segment defining the switchgear cabinet.

34. The switchgear cabinet according to claim 33, wherein the first and second end caps are approximately equal in surface area, the first end cap having a mounting plate for attaching electrical components and equipment of the switchgear cabinet and a supports thereof and the second end cap having a plate with a plug panel formed therein.

35. The switchgear cabinet according to claim 33, wherein the first end cap has surface stamps on its surface for the arrangements of end cap items selected from the group consisting of plugs, plug panels, electrical components or combinations thereof.

36. The switchgear cabinet according to claim 33, wherein at least one of the first and second outer segments and the central segment have substantially the same structure and are interchangeable among each other.

37. The switchgear cabinet according to claim 33, wherein a central segment and at least one of the first and second outer segments have different widths.

38. The switchgear cabinet according to claim 25, wherein at least one of the first and second cabinet segments has a U-shaped, planar frame construction with a horizontally extending rectangular base surface, which is surrounded by frame parts and which has the planar lateral surface protruding laterally and perpendicularly.

39. The switchgear cabinet according to claim 38, wherein at least one of the base and the lateral surfaces of a cabinet segment is configured to form an opening therethrough.

40. The switchgear cabinet according to claim 38, wherein a frame lateral surface of the cabinet segment has an opening, which is sealed by a stampable plate and the opposite surface to which has a closed surface.

41. The switchgear cabinet according to claim 40, wherein electrical switches directed outwards are arranged on the stampable plate.

42. The switchgear cabinet according to claim 33, wherein the surface of at least one of the first and second outer segments pointing outwards is covered on each of its longitudinal sides by an end cap.

43. The switchgear cabinet according to any claim 33, wherein the central segment is in each case connected to a longitudinal frame part and a lateral frame part with the corresponding frame part of an outer segment.

44. The switchgear cabinet according to claim 33, wherein the lateral frame part of the central segment form closed surfaces on both sides.

45. The switchgear cabinet according to claim 32, wherein the central segment and at least one of the first and second outer segments have openings on their closed base surface.

46. The switchgear cabinet according to claim 25, wherein the switchgear cabinet comprises a converter box usable in its function as converter cabinet in which the equipment and devices for at least one converter units are arranged for the pitch drive, and a storage battery box usable as in its function as container for further rechargeable voltage sources in the form of accumulators or capacitors.

47. The switchgear cabinet according to claim 46, wherein the converter box and the storage battery box each have a central segment and laterally arranged outer segments, the outwardly directed lateral surface of which is in each case covered by the end caps.

48. The switchgear cabinet according to claim 46, wherein both the converter box and the storage battery box have a plurality of U-shaped segment parts which are provided either as outer segment with end caps or are usable as the central segment.
