Definitions

  • the invention concerns a wind power installation comprising a pylon, a foundation for the pylon and an energy transfer unit for transfer of the current generated to the power network.
  • Wind power installations of that kind are well-known from the state of the art.
  • the energy stored in the wind is converted into electrical energy by way of a rotor which rotates in the wind and a generator which is driven by the rotor.
  • the rotor In order to be arranged at a height of optimum wind speed, the rotor is generally disposed at the tip of a tower or pylon.
  • the entire installation By virtue of the not inconsiderable weight of the installation overall and the loadings involved with high wind speeds, the entire installation must be anchored in the ground by means of a foundation.
  • That energy transfer unit which usually includes a transformer is in that case disposed at some distance from the pylon and by virtue of its also not inconsiderable weight is usually anchored to the ground by a foundation.
  • the object of the invention is to avoid the above-mentioned disadvantages of the state of the art and to provide a wind power installation of the kind set forth in the opening part of this specification, which can be set up even in inhospitable areas and which effectively makes sabotage by unauthorised parties more difficult.
  • the advantages of the invention are in particular that there is no need for an additional foundation for the energy transfer unit to be provided in the ground.
  • the invention provides that the foundation for the pylon, which is usually of a very stable nature in any case by virtue of the demands referred to in the opening part of this specification, is also used for supporting the weight of the energy transfer unit. The invention therefore completely saves on the costs of an additional foundation.
  • an enclosure for the pylon which is already present means that an energy transfer unit which is mounted directly to the pylon on the foundation of the pylon can also be safeguarded against unauthorised parties by the fencing enclosure.
  • a pylon which is hollow in its interior can accommodate the energy transfer unit in its interior so that the energy transfer unit, even without an enclosure around the pylon, is safeguarded against sabotage by unauthorised parties.
  • the power lines from the pylon to the energy transfer unit can be kept very short as by virtue of its position in the interior of the pylon, the energy transfer unit is in the closest possible proximity to the power cables which extend in the interior of the pylon and which run from the current generator to the energy transfer unit.
  • the energy transfer unit is completely protected from the weather by virtue of its being positioned in the interior of the pylon.
  • a further, particularly advantageous embodiment of the invention is distinguished in that the energy transfer unit is fixed externally to the pylon.
  • the energy transfer unit is admittedly not weather-proofed as in the case of the above-mentioned embodiment; it is however advantageously exposed to the cooling wind so that for example it is possible to eliminate cooling for a transformer of the energy transfer unit, as is possibly necessary in particular in hot areas.
  • possible malfunctions of the energy transfer unit which for example could cause a fire do not spread directly to the overall installation.
  • a particularly preferred embodiment is one in which the energy transfer unit is disposed approximately at the height of an overland power line of the power network, to which the wind power installation is connected. This embodiment therefore provides that the power is transferred directly to the overland power line directly at the height thereof so that there is no need for any additional lines from the energy transfer unit to the not inconsiderable height of conventional overland power lines.
  • overland power lines also do not have to be taken down to the proximity of the ground so that this embodiment is also distinguished by enjoying an increased level of safeguard against sabotage.
  • FIGURE of the drawing diagrammatically shows the wind power installation according to the invention.
  • the FIGURE shows in its left-hand part a partly sectional wind power installation 1 .
  • the FIGURE shows in its right-hand part a wind power installation 2 .
  • the FIGURE shows the wind power installation 1 partly in section as viewed from the side.
  • the wind power installation 2 is also shown as a side view, but not in section.
  • the wind power installations 1 and 2 are identical in terms of their structure so that here only the wind power installation 1 which is shown at the left will be described in respect of its structure.
  • the wind power installation 1 has a tower or pylon 4 which is arranged perpendicularly relative to the ground 6 .
  • the pylon 4 of the wind power installation 1 is anchored in the ground 6 by a foundation 8 .
  • the foundation 8 is of an enlarged diameter, in relation to the diameter of the pylon 4 .
  • a machine housing 12 is mounted to the tip 10 of the pylon 4 .
  • Ancillary assemblies (not shown) of the wind power installation 1 are disposed in the machine housing 12 .
  • a generator 14 is disposed directly adjoining the machine housing 12 .
  • the generator 14 converts the rotational energy of the rotor hub 16 connected thereto into electrical energy.
  • the rotor hub 16 is caused to rotate by rotor blades 18 which rotate in the wind by virtue of an aerofoil profile.
  • the electrical energy produced is made available by the generator 14 by way of lines 20 to a transformer 22 which operates as an energy transfer unit.
  • the transformer 22 feeds the transformed electrical energy by way of circuit breakers 24 into overland power lines 26 .
  • the overland power lands lines 26 are suspended on masts 30 by way of insulators 28 .
  • the transformer 22 is arranged directly at the pylon 4 .
  • the transformer 22 is disposed on a platform 32 .
  • the transformer platform 32 At its end remote from the pylon the transformer platform 32 has a limiting wall 34 .
  • the platform 32 is disposed substantially at the height of the overland power lines 26 so that the fixing points 36 which serve above the circuit breakers 24 for fixing the overland power line 26 above the transformer 22 to the pylon 4 are disposed substantially at the same height as the insulators 28 . In the illustrated embodiment therefore the pylon 4 also performs the function of a mast 30 .
  • the energy transfer unit is positioned internally in a pylon is shown by the arrow to the broken line box in the FIGURE.
  • the pylon 4 is hollow in its interior such that the transformer 22 is inside of and fixed internally to the pylon 4 by the platform 32 .
  • the right-hand half of the FIGURE shows a wind power installation 2 which is of the same structure as the wind power installation 1 .
  • the transformer 38 is mounted turned through 90° on the side of the wind power installation 2 , which is towards the person viewing the drawing.
  • the FIGURE does not show a limiting wall for the platform 40 of the wind power installation, such wall corresponding to the limiting wall 34 of the platform 32 .
  • the transformer 38 however is also connected by way of circuit breakers 42 to overland power lines 26 fixed to the pylon 46 at fixing points 44 .
