Abstract

The invention relates to a ventilation or air-water separation system for a wind generator having a wind generator hub, which supports blades and is arranged rotatably about a rotation axis on a nacelle. The wind turbine hub is protected by a rotor that isolates the exterior from the interior and is arranged to rotate with the wind turbine hub. The system has an inlet in the spinner and an outlet inside the wind generator.

Description

technical field [0001] The invention relates to a ventilation or water separation system for a wind generator having a wind generator hub supporting blades arranged to rotate about a rotation axis supported by a nacelle. The wind turbine hub is protected by a spinner that isolates the exterior from the interior and is arranged to rotate with the wind turbine hub. The system has an inlet in the spinner and an outlet inside the wind generator. Background technique [0002] The increased size of modern wind turbines has led to increased awareness and attention to the thermal control of heat generating components in the wind turbine hub and nacelle. The need for thermal control is due to the increased frictional heat emitted by major components such as main bearings, gearboxes, generators, inverters and control / monitoring electronics. The increased size of the main components also increases the risk of having large thermal stresses caused by temperature differences across the ...
