Problems solved by technology

[0006] However, it has been found that such a construction produces significant disadvantages in terms of ergonomics and operational safety, since in particular the accessibility of the individual parts of the tower can be severely affected by the lattice-shaped configuration of the lower tower section
It has also been shown that with such a hybrid construction the construction of the lattice support can be expensive, since it has to withstand high forces and be designed accordingly
This leads to high expenses and high costs

Embodiment Construction

[0042] figure 1 a shows a longitudinal section of a first embodiment of a tower according to the invention, while figure 1 b shows figure 1 a Cross-sectional view of the embodiment shown.

[0043] The tower 1 is part of a wind generator with a nacelle and a rotor (not shown). Column 1 has an upper column section 2 and a lower column section 4 . The upper column section 2 comprises a tube column 6 . The lower tower section 4 comprises a lattice frame 8 and an intermediate pipe 10 which is arranged centrally inside the lattice frame 8 . The intermediate tube 10 generally has a smaller diameter than the tube column 6 of the upper column section 2 . The tower 1 also comprises an intermediate part 12 through which the lattice frame 8, the intermediate pipe 10 and the pipe tower 6 are connected to each other. The intermediate pipe 10 is connected at its lower end to the base (not shown) of the column 1 and at its upper end to the intermediate part 12 .

Abstract

A tower for a wind turbine may include an upper tower portion and a lower tower portion. The upper tower portion may include a tubular tower, and the lower tower portion may include a lattice tower. To improve ergonomics and work safety and make it possible to obtain a structural design with optimized forces, the lower tower portion may include a central tube positioned centrally within the lattice tower. Further, the central tube may have a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion. The tower may also include a transition piece between the upper tower portion and the lower tower portion. The transition piece may join the tubular tower of the upper tower portion and the central tube of the lower tower portion.

Description

technical field [0001] The invention relates to a tower for a wind power generator, having an upper tower section and a lower tower section, wherein the upper tower section comprises a tube tower, wherein the lower tower section comprises a lattice frame. The invention also relates to a wind power generator. Background technique [0002] Especially for wind turbines or wind energy generators, especially on land, the trend is towards higher and higher hub heights (the height at which the hub of the wind turbine rotor is located relative to the ground). During this period, heights in excess of 100 meters are desired. As a result, higher and more stable wind speeds can be used, and thus the efficiency of the wind turbine can be improved, especially in weak wind regions. [0003] A taller tower with a larger and more powerful generator or rotor will also result in a larger wall thickness and diameter of the tower section to meet the resulting higher structural mechanics requir...
