Benefits of technology

[0007] The present invention provides a wind-power system, which can be erected more easily and thus also more economically and more quickly, and in which the power module is not absolutely necessarily in the region of the tower base.
[0009] The segments of the current-carrying means are thus prefabricated and preferably attached to the tower segments before the tower is erected from the individual tower segments. Thus, it is no longer necessary to draw cables through the tower in a complicated process after erecting the tower. Due to the means according to the invention, the total erection time of the wind-power system can be shortened and the costs for the erection reduced, without having to take into account any technical disadvantages.
[0014] If the current-carrying means are formed as cables, for bypassing flanges or parts projecting from the tower inner wall, the lengths of the cable sections can be dimensioned in the tower segments so that bypassing these areas is possible without a problem.
[0016] In order, on the one hand, to protect service personnel from contacting the busbars when climbing through the interior of the tower and to guarantee electrical insulation and, on the other hand, to protect the current-carrying means from damage, in another configuration, a protective sleeve, especially a protective sheet, is provided, which is rigidly connected, for example, to the inner wall of the tower and protects the current-carrying means completely from touch. This protective sleeve can also be split into individual segments, which are premounted to the tower segments just like the segments of the current-carrying means. This configuration further shortens the time and simplifies the construction of the wind-power system.

Problems solved by technology

This is a costly process, because the cables must be installed in a separate procedure over the entire height of the tower.

Embodiment Construction

[0026] The wind-power system 1 shown schematically in FIG. 1 and described in German Pat. No. 10 152 557 has a tower 2 with a foundation 3, a gondola 4 supported so that it can rotate in the region of the top of the tower, as well as a power module 7 arranged in the region of the tower base, for example, in a small, separate housing. Within the gondola 4, there is a rotor supported so that it can rotate about a horizontal axis with several rotor blades 5, as well as an electrical generator 6. The rotor is set in rotation by the force of wind acting on the rotor blades 5 and drives the generator 6 for generating electrical power.

[0027] For transmitting the energy generated by the generator 6 to the power module 7, which has numerous electrical units, such as a transformer or optionally a rectifier for further processing of the electrical power before it is fed into the power network or transmitted to a load, according to the invention, there are busbars, preferably two busbars, atta...

Abstract

The invention concerns a wind-power system for generating alternating current with a tower built from several tower segments, with a generator arranged in the region of the tower head, with a power module, and with current-carrying means for carrying the generated power from the tower head. In order to enable quicker, simpler, and thus more economical construction of the wind-power system, according to the invention, the current-carrying means are premounted in a segmented way in the tower segments and the power module is arranged at least partially in the region of the tower head and / or removed from the tower base.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention concerns a wind-power system with a tower built from several tower segments, with a generator for generating power arranged in the region of the tower head, with a power module, and with current-carrying means for carrying the generated current from the tower head. [0003] 2. Description of the Related Art [0004] In known wind-power systems, the electrical power module of a wind-power system, which includes electrical units, such as transformers, service cabinets, optionally, rectifiers, medium-voltage networks, low-voltage distribution devices, etc., is arranged underneath the level of the generator and frequently in the region of the tower base of the wind-power system. For all or some of these components, usually a small, separate building is provided outside of the wind-power system. [0005] In order to transmit the electrical energy generated by the generator, which is arranged within a gondola in t...
