Abstract
A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least one auxiliary unit. The auxiliary unit accommodates a at least one component, e.g. a converter or transformer. To provide efficient transportation, lower costs and easier assembly, the operative component is suspended directly on the main unit.
Claims21
A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly supporting a rotor, the nacelle further housing a power conversion assembly, the nacelle comprising:
- a main unit arranged to be connected to the wind turbine tower and housing the rotor-supporting assembly, and
- at least one auxiliary unit housing an operative component forming part of the power conversion assembly,
- wherein:
- the main unit and the auxiliary unit are separate units configured to be connected by a unit fixation structure at an interface,
- the operative component is suspended directly on the main unit, and
- the main unit and the at least one auxiliary unit are arranged side by side in a direction transverse to a rotational axis defined by the rotor-supporting assembly.
A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly supporting a rotor, the nacelle further housing a power conversion assembly, the nacelle comprising:
- a main unit configured to be connected to the wind turbine tower, wherein the main unit comprises at least one wall that defines an interior, and wherein the main unit includes a main frame and the rotor-supporting assembly in its interior, and wherein the main frame is configured to form part of a load path from the rotor into the wind turbine tower, and
- at least one auxiliary unit separate from the main unit and configured to be connected to the main unit by a unit fixation structure at an interface, wherein the at least one auxiliary unit comprises at least one wall that defines an interior, and wherein the at least one auxiliary unit includes an operative component forming part of the power conversion assembly in its interior, and
- a first suspension structure configured to extend from the interior of the main unit to the interior of the at least one auxiliary unit for suspending the operative component directly on a main frame in the main unit.
