  • Patent number: 8866330
    Abstract: The invention relates to a tower for a wind turbine and to a cable guide therefor, wherein a nacelle for the wind turbine is arranged on the tower such that it can rotate by means of the azimuth bearing about a vertical axis which runs in the longitudinal direction of the tower. Current-conducting cables are routed in the tower of the wind turbine out of the nacelle from electrical components to the ground. The tower has at least two bundling devices which are suitable for joining the individual cables which run longitudinally in the tower together to form a cable bundle with the cables fixed with respect to one another. The bundling devices are attached to the cables between an upper and a lower area of the cable bundle. In this case, geometric configuration of the bundling device ensures that at least between three cables it is not below a specific minimum distance.

  • Publication number: 20120224799
    Abstract: The present invention relates to a bearing device for a wind turbine, wherein the bearing arrangement has two bearing partners, which are pivoted arranged relative to each other over a common axis. A gliding pad acting in an axial direction is provided between the bearing partners. The object of the invention is to provide a bearing arrangement for a wind turbine, which among others avoids the disadvantages of the prior art. In particular, a maintenance-friendly and force flow-optimized arrangement of the gliding pads is to be enabled. The replaceability of the gliding pads is to be improved in a simple and cost-effective manner by disposing the individual gliding pads in pockets between the two bearing partners, wherein the pockets are provided in the material of the machine frame. Additionally, the option exists to use the bearing arrangement at the same time as an active brake.

  • Publication number: 20110062720
    Abstract: 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.
