Embodiment Construction

[0042] in figure 1 Shows a wind turbine 1 with a tower 2, with a machine room 8 rotatably supported on the tower 2 about the tower axis 4 of the tower 2, and a wind turbine 1 arranged in the machine room 8 through a rotor shaft Rotor 9 connected to the generator. In wind tracking (also called "yaw"), the machine room 8 is rotated in a horizontal plane around the tower axis 4 of the tower 2 so that the rotor 9 rotates perpendicular to the wind and thus maximizes energy production. Since the wind direction changes or even rotates during the operation of the wind turbine 1, it is possible that the machine room 8 repeatedly rotates around a unique axis.

[0043] The statements of the axial direction 5, the radial direction 6, the circumferential direction 7 and the statements for the upper part and the lower part used below are relative to the longitudinal axis of the erected tower 2 of the wind turbine 1.

Abstract

The invention relates to a tower for a wind turbine and to a cable guide for a tower of a wind turbine, wherein a machine housing 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-carrying cables, such as power cables, are routed in the tower of the wind turbine out of the machine housing from electrical components to the ground. These comprise a multiplicity of cables, for example a plurality of cables for electrically carrying individual phases of alternating current, in particular three-phase alternating current, cables for ground conductors and / or signal and control cables. One object of the invention is to specify improved routing of the cables which, inter alia, avoids the disadvantages of the prior art.One particular aim is to ensure that the current load capacity of the cables is ensured, and / or that wear between the cables is reduced. According to the invention, the object is achieved by the features of the main claim 1, by the tower having at least two looming apparatuses, which are suitable for joining the individual cables which run longitudinally in the tower together to form a cable loom with the cables fixed with respect to one another. The looming apparatuses are attached to the cables between an upper and a lower area of the cable loom. In this case, geometric configuration of the looming apparatus ensures that a specific minimum separation at least between three cables is not undershot.

Description

Technical field [0001] The present invention relates to a tower for a wind turbine and a cable guide for a tower for a wind turbine, wherein the tower can be wound vertically on the tower by means of an azimuthal bearing (Azimutlager) The machine room of the wind turbine is arranged in such a way that the axis extending in the longitudinal direction of the frame rotates. A generator for generating electric energy is provided in the machine room, and the generator can be driven by the rotor of the wind turbine. The azimuth bearing realizes the horizontal orientation of the machine room according to the wind direction, the so-called wind tracking of the wind turbine (Windnachführung). For the automatic orientation of the machine room, one or more azimuth driving devices are arranged at the azimuth bearing, which are connected to the frame of the nacelle in a non-rotatable manner. Here, the azimuth bearing must guide the bearing forces that occur, such as thrust, centrifugal forc...
