| 20120039011 | TRANSMISSION DEVICE FOR A WIND TURBINE - The invention relates to a transmission device for a wind turbine, having a holder, a sliding contact device having pressing means, and at least one electrode having adjustment means for transmitting lightning current. The electrode can form a spark gab having a sparking distance S together with a ring electrode, wherein the ring electrode can be arranged on the rotary device, or can be connected to a grounding device that cannot be rotated with respect to the rotary device. To improve the transmission, the holder is rotationally fixed arranged on the rotary device, or arranged in a non rotatable manner with respect to the grounding device. Furthermore, the electrode is arranged in a movable manner relative to the holder by means of a tracking device having support means. The electrode is supported by way of the supporting means relative to the rotary device or the ring electrode such that the sparking distance S can not fall below a minimum dimension. | 02-16-2012 |
| 20120010852 | METHOD FOR MONITORING WIND TURBINES - A method for determining damage to a rotor blade of a wind turbine, includes at least the following time-domain-analysis steps: measuring the vibrations of a rotor blade by means of an acceleration sensor; obtaining event-time intervals, in which the amplitudes of the measurements steadily exceed a threshold; obtaining the number of these event-time intervals in at least a predetermined analysis time interval; and sending an error signal, when the obtained number of the event-time intervals is above a predetermined threshold for a predetermined analysis time interval. | 01-12-2012 |
| 20110299975 | BRAKE SYSTEM FOR A WIND TURBINE - The invention relates to a brake system for a wind turbine having a machine house rotatably mounted in horizontal plane on a tower, at least one stop brake ( | 12-08-2011 |
| 20110062720 | CONTROL BOX FOR A WIND TURBINE - The invention relates to a control box for arranging in a rotor hub of a wind turbine that can be rotated about a rotational axis. Such control boxes receive electrical components such as relays, inverters, sensors and the like, in the inner region thereof, which is defined by a wall, said components being required for the control of sheet displacement systems, also called pitch systems. Spurious particles can find their way into the control box during maintenance or even via air inlets and outlets. Especially dangerous parts are electro-conductive spurious parts that can trigger a short circuit (wires, cable parts, washers, screws etc.) and mechanically relevant bodies that can block ventilators, for example. Wind turbines are also known from prior art, wherein magnets are provided in the control boxes in the rotor hub, and ferro-magnetic spurious particles can thereby be fixed inside the control box. The aim of the invention is to provide a control box for a wind turbine, wherein the fault tolerance of the control box is increased. To this end, according to the features of claim | 03-17-2011 |
| 20100259045 | Wing Energy Installation with Enhanced Overvoltage Protection - A wind energy installation and method for production of electrical energy from wind energy by means of the wind energy installation having a rotor which can be driven via wind power and has rotor blades whose pitch angles can be adjusted by means of at least one adjusting apparatus, which can be driven electrically, in order to influence the rotational speed of the rotor, wherein a generator rotor is connected to the rotor, and the generator rotor together with the stator forms a generator, | 10-14-2010 |
