Gearbox
The gearbox is a custom-built, three-stage, planetary-helical
design. The first two high-torque stages are of a helical
planetary design. The high-speed stage is of a normal
helical design and provides the offset of the high-speed
shaft that is needed to allow passage of power and control
signals to the pitch systems.
The gearbox is shaft-mounted and the main shaft torque
is transferred to the gearbox by a shrink-disk connection.
The gearbox is supported in the nacelle with flexible rubber
bushings.
The gearbox is fitted with an oil conditioning system. All
bearings are lubricated with oil fed directly from a large
in-line filter and are cleaned by an off-line filter unit.
The gearbox is fitted with sensors for monitoring temperature,
oil pressure, and vibration levels.
Generator
The generator is a fully-enclosed, asynchronous generator.
It has a squirrel-cage rotor without slip-rings. The generator
rotor construction and stator winding are designed
for high efficiency at partial loads. The generator is protected
with thermal switches and analogue temperature
measurement sensors.
It is fitted with a separate thermostat-controlled ventilation
arrangement. Air is recirculated internally in the
generator and heat is transferred through an air-to-air
heat exchanger that separates the internal environment
in the generator from the ambient air.
Mechanical brake
The mechanical brake is fitted to the gearbox high-speed
shaft and has two hydraulic calipers.
Yaw system
The yaw bearing is an internally geared ball bearing fitted
with a hydraulic disc brake. Six electric planetary gear motors
drive the yawing.
Tower
The SWT-3.6-120 wind turbine is mounted on a tapered,
tubular steel tower. The tower has internal ascent and
direct access to the yaw system and nacelle. It is equipped
with platforms and internal electric lighting.
