Abstract:
The present disclosure is directed to a cable securement assembly for protecting cables and/or cable bundles within a wind turbine. The cable securement assembly includes a cable spacer having an inner surface and an outer surface separated by a thickness and one or more fastening components. The inner surface defines an open center configured to receive the plurality of cables therein. The inner surface defines a plurality of cable locations defined by one or more through holes configured through the thickness. The one or more fastening components are configured to secure one or more of the plurality of cables at each cable location via the through holes.
Abstract:
A slip ring system for a wind turbine for electrically connecting a first electrical device and a second electrical device, wherein the first electrical device is mounted to a rotor of the wind turbine, and the second electrical device is mounted to a nacelle of the wind turbine, is provided. The slip ring system comprises a slip ring apparatus and a rotational damping apparatus, with which an electrical connection between the first electrical device and the second electrical device can be established. The slip ring apparatus has a rotatable component with a rotatable electrode and a non-rotatable support electrode, wherein the rotatable electrode is electrically connected to the first electrical device, and the support electrode is electrically connected to the second electrical device. The non-rotatable support electrode and the rotatable electrode are arranged with respect to each other's position and configured such that an electrical connection can be established between the non-rotatable support electrode and the rotatable electrode. The rotational damping apparatus connects the turbine rotor and the slip ring apparatus. The rotational damping apparatus prevents vibrations at least partially from migrating into the rotatable component. The rotational damping apparatus comprises a slip ring portion, a shaft portion and a damping portion. The slip ring portion is mounted to the rotatable component and the shaft portion is adapted for being mechanically connected to the turbine rotor for rotating with the turbine rotor.
Abstract:
A wind turbine is provided. The wind turbine includes a transformer having a low-voltage side and a high-voltage side. The transformer is configured to step up a voltage of the low-voltage side of the transformer to a voltage of an external grid. The wind turbine further includes an electrical power generating unit which is connected to the low-voltage side of the transformer and configured to feed an ac-power to the low-voltage side of the transformer. A charging device of the wind turbine is connected to the low-voltage side of the transformer and configured to charge the low-voltage side of the transformer when the generator does not feed ac-power to the low-voltage side of the transformer.
Abstract:
The present disclosure is directed to a wind turbine drip loop cable securement assembly. The assembly includes at least one flexible ring component and a plurality of flexible straps circumferentially mounted to the flexible ring component. More specifically, the flexible ring component has an inner surface and an outer surface separated by a thickness. The inner surface defines an open center configured to receive the one or more cables therein. Further, the flexible straps have a first end and a second end. Thus, the first end is configured to be mounted to an interior wall of a tower of the wind turbine, whereas the second end is configured to be mounted to the outer surface of the ring component so as to minimize movement of the cables.
Abstract:
A system for installing an electric cable in a tower of a wind turbine is provided. This system comprises at least one cable drum designed for carrying and controlled releasing of at least one electric cable for a wind turbine. Further, the system contains a drum support for rotatably supporting said at least one cable drum, wherein the drum support is configured to be mounted within an interior of a segment of the tower.
