[0001] FLY-P-04569-WP2 - 1 - 12 / 17 / 2025

[0002] Device for suspending conductor rails in wind turbines

[0003] State of the art

[0004] The invention relates to a device for fastening and storing busbars in wind turbines according to the preamble of claim 1.

[0005] In wind turbines, it is known to provide a multitude of interconnected busbars for transmitting the electricity generated in a generator in the area of ​​the top of a tower of the wind turbine to a grid station located at the base of the wind turbine. These busbars extend between the base area and the head or top of the tower of the wind turbine and usually have a length of approximately 3m each.

[0006] The tower of a wind turbine typically consists of several stacked tower segments, each with a sleeve-like shape. During the manufacturing process, the conductor rails for power transmission are attached to the inner wall of each tower segment, forming a conductor rail section within each segment. After the individual tower segments are assembled on-site, the individual conductor rail sections are electrically connected via connecting rails. Within the tower segment, the individual conductor rails of a conductor rail section are elastically attached or suspended by a mounting bracket and an elastomeric element acting as an intermediate element. This bolt is anchored in the wall of the tower segment.FLY-P-04569-WP2 - 2 - 12 / 17 / 2025.

[0007] During assembly and especially during operation of the wind turbine, mechanical stresses arise over time, for example, due to differing thermal expansion rates between the steel tower and the conductor rails, which are typically made of aluminum. These stresses occur within and between individual conductor rail sections and between sections of the conductor rails. The elastic suspension of the conductor rails by elastomer elements is designed to compensate for these stresses. Furthermore, the elastic suspension of the conductor rails via the elastomer elements allows the weight of each conductor rail to be partially transferred to the conductor rails located below it.

[0008] According to current technology, the conductor rails in all installed turbines are rigidly connected to the tower wall approximately every 3 meters along the entire tower height using a partially flexible mounting system. As tower walls are increasingly designed with less rigidity, the conductor rail housing must compensate for ever greater tower movement. This leads to enormous mechanical stress on all bolted connections of the housing. Consequently, various bolted connections are destroyed, and the housings can rub against each other, generating metal dust. This metal dust settles on horizontal components, including those inside the conductor rail housing. Thus, the actual conductor rail becomes coated with highly conductive material, which can lead to significant malfunctions and damage, especially when condensation forms inside the wind turbine due to weather conditions.

[0009] In addition, the defects occurring in the bolted connections cause a steadily increasing imbalance in the distribution of forces and load transfer of the conductor rails in the support system. If several bolted connections on a support element of the support system are defective, the support element below must also bear the loads of the conductor rail above it, which, also in conjunction with vibrations occurring in the tower, leads to further damage to the bolted connections.

[0010] This increases the risk of potential and, in particular, severe damage and the associated downtime of the wind turbine. Furthermore, increased maintenance is required during operation of the wind turbine.

[0023] The fastening device advantageously comprises two opposing and preferably end-mounted connecting sections for connection to the at least one support element. These preferably extend from the, in particular, U-shaped base body of the fastening device essentially perpendicular to the longitudinal direction of the fastening device. The fastening device may also have additional second connecting sections, which are arranged opposite the aforementioned first connecting sections and can, in particular, serve for connection to a further fastening device, especially one arranged below in the longitudinal direction of the tower. In this case, additional support elements are advantageously provided, which are arranged or can be arranged between a first and a second connecting device.

[0024] The respective support element preferably comprises at least one steel cable and / or at least one threaded rod. Furthermore, the respective support element advantageously comprises end-mounted connecting elements, such as retaining eyes, by means of which the respective support element can be arranged on the suspension device and / or the fastening device or connected to the respective device.

[0032] The aforementioned device according to the invention can be designed for the permanent arrangement of one or more cable harnesses in a wind turbine, in addition to the arrangement of busbars.

[0033] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing.

[0034] This shows in:

[0036] Fig. 2 is a schematic representation of a front view in the area of ​​the suspension device of the apparatus within the wind turbine according to Fig. 1 according to a preferred embodiment.

[0037] Fig. 3 shows a schematic representation of a perspective front view in the area of ​​a connecting rail, which is arranged between two longitudinally adjacent conductor rails in the tower of a wind turbine according to Fig. 1.

[0038] Fig. 4 shows a front view of a connecting rail according to Fig. 3 with highly simplified representations of the connecting sections and retaining devices, and

[0039] Figs. 5a-h show several views of another preferred embodiment of the device.

[0040] Identical components or components with the same function are provided with the same reference numbers in the figures.

[0041] Fig. 1 shows a basic and highly simplified representation of the structure of a wind turbine 40, comprising a base 14, a tower 20, and a nacelle or tower head 30, in which, among other things, rotor blades 13 are rotatably arranged or mounted. A generator 9 is located inside the nacelle 30, which converts the rotational movement of the rotor blades 13 into electrical energy. This generator is coupled to a busbar assembly 15 via an upper connecting line 9a or an upper connection. The busbar assembly 15 is arranged along the entire length or height of the tower 20 and extends in a longitudinal direction L parallel to the tower's longitudinal extent. In the area of ​​the base 14 of the tower 20, the busbar assembly 15 is connected to a substation 12 by means of a further, lower connecting line 12a or a lower connection. FLY-P-04569-WP2 - IQ - 17.12.2025

[0042] Tower 20 consists, for example, of three stacked, sleeve-like tower segments 21a-c. Each such tower segment 21ac has a typical length of approximately 20m, resulting in a total height of tower 20 of approximately 60m. Additional segments can be incorporated to achieve a greater tower height.

[0043] The busbar assembly 15 can be formed during the production of the tower segments 21 ac. Individual busbar sections, each comprising a plurality of busbars 10a,... , n, are arranged on the respective tower segments by means of associated connecting elements or holding devices 8, wherein, in the assembled state of the tower, the busbar sections form the busbar assembly 15 by means of appropriate contact at the connection points of the segments.

[0044] Alternatively, and preferably according to the invention, the busbar assembly 15, comprising a plurality of busbars 10a, ... ,n arranged adjacent to one another, is arranged in the tower 20 after the tower has been erected, i.e., after the individual tower segments 21 ac have been connected by means of the suspension device 1 according to the invention. In contrast to the prior art, the individual busbars 10a, ... , n can either be made longer and / or the number of retaining devices 8 can be significantly reduced. In addition, it is possible to simplify the design of the respective retaining devices 8, since these now preferably only need to prevent the busbars or the busbar assembly 15 from swinging in the tower 20, particularly when the tower is moving, and, unlike the prior art, do not need to be designed to bear the weight of the busbars 10a, ... , n or the busbar assembly 15.This significantly reduces the damage to the busbar assembly 15 known from the prior art, maximizes the damage-free operating time of the wind turbine 40, and simultaneously minimizes maintenance requirements.

The fastening device 2 is preferably designed as a U-shaped element for attachment to the connecting rail 11a, which connects two adjacent conductor rails 10a, b. The fastening device 2 preferably comprises two opposing and preferably end-arranged connecting sections 6a for connection to the respective support element 3 and the associated suspension device 1, wherein the connecting sections 6a preferably extend substantially perpendicular to a longitudinal direction of the fastening device 2 and thus also substantially perpendicular to the tower's longitudinal direction L.The fastening device 2 and / or the support elements 3 may include adjusting means for adjusting a respective longitudinal extension, so that the suspension position of the associated connecting rail 11a FLY-P-04569-WP2 - 13 - 17.12.2025 and / or the associated busbar 10a in the tower 20 can be adjusted.

[0052] By means of the arrangement as shown in Fig. 2, one or the uppermost connecting rails 10a of the busbar assembly 15 are permanently arranged or suspended in the tower 20 by means of the suspension device 50 according to the invention. This allows the weight force of the suspended connecting rail 10a and the busbars of the busbar assembly 15 connected to it to be effectively transferred into the tower 20 by means of the suspension device 50.

[0053] For the secure suspension of the underlying busbars 10b, ... ,n and the connecting rails 11b, ... ,n linking them at predefined intervals, the device advantageously comprises a plurality of fastening devices 2, as shown in Figures 1 and 3. The fastening devices 2 are designed for connection to busbars 10a, ... ,n and / or connecting rails 11a, ... ,n arranged at predefined intervals in the longitudinal direction L of the tower. Advantageously, the additional fastening devices 2 are each designed for arrangement on a respective connecting rail 11b, ... ,n.

[0054] To connect the individual connecting rails 11a, ..., n, these are connected to one another by additional support elements 3 of the device 50, which extend essentially parallel to the current and connecting rails 10a, ..., n, 11a, ..., n. The respective fastening devices 2 include additional connecting sections 6b on a side opposite the connecting sections 6a, which are designed essentially analogously to the first connecting sections 6a. In this way, a plurality of connecting rails 11a and the associated current rails 10a, ..., n can be connected to the suspension device 1 for weight force transmission.

[0057] As schematically shown in Fig. 4, the holding device 8 preferably comprises a plurality of bolts 8a extending perpendicular to the inner wall 24 of the tower 20 and advantageously further associated elastomeric bearings (not shown). The holding device 8 is preferably designed such that it primarily prevents the busbar assembly 15 from oscillating within the tower 20. Furthermore, the holding device 8 is advantageously designed to absorb essentially no forces in the longitudinal direction L of the tower. In particular, the holding device 8 should not serve to absorb the weight of the busbar assembly 15.
