Definitions

  • the present invention relates to a method for exchanging a transformer of a wind energy plant.
  • transformers are typically provided at the bottom of the tower of a wind turbine.
  • the transformers can be used to transform an output voltage of a power cabinet of a wind turbine to a voltage that is needed for an electrical network to which the wind turbine is connected.
  • the transformers typically have only a limited life, so that it may happen during the life of the wind turbine that a transformer must be replaced. So far, special mobile cranes with heavy load tips were needed to replace the transformers.
  • a crane jib can be driven through a door opening in the tower of the wind turbine to strike the transformer and lift out. Since the dimensions of the door openings are limited, a crane boom with a heavy load tip is needed.
  • This object is achieved by a method for replacing a transformer of a wind turbine according to claim 1.
  • a method for replacing a generator of a wind turbine is provided.
  • the generator is provided inside a tower of a wind turbine and the tower has a door opening.
  • a exchange crossbar is over a first attachment point attached to a crane hook of a mobile crane.
  • a first end of the exchange crossbar is inserted with a second attachment point through the door opening in the tower.
  • the transformer to be replaced is attached to the second stop point of the first end.
  • a balance weight is attached to the second attachment point at the second end of the transfer truss.
  • the weight of the balance weight may optionally substantially correspond to the weight of the transformer to be replaced.
  • the second end of the transfer bar is tilted until the transformer is at the height of the door opening, and the crane hook is moved until the transformer to be replaced is outside the door opening.
  • a new transformer to replace the old transformer is provided as a balance weight, and the exchange crosshead is rotated 180 °, and the new transformer at the second attachment point at the second end of the exchange crossbar is guided into the door opening.
  • the new transformer is lowered to the operating position by raising the first end of the transfer truss or tilting the truss.
  • first and second pulley blocks may each be connected to the first anchorage point and the second end of the transfer truss, and then the second end is moved up or down by the second pulley block so that the transfer truss is tilted can be.
  • a further first attachment point is provided for the exchange truss. While the first attachment point is provided in the center of gravity of the exchange cross member, the further first attachment point is provided outside the center of gravity, so that also different heavy loads can be handled at the first and second end of the exchange crossbar.
  • the present invention also relates to a transfer beam for use in a method of replacing the transformer.
  • the exchange cross-piece has an elongate body, a first attachment point for receiving a crane hook of a crane and in each case a second attachment point at the first and second end of the exchange cross member respectively for receiving a transformer to be replaced and a Balance weight on.
  • the first attachment point is located essentially in the center of gravity of the exchange crossbar.
  • the invention relates to the idea to provide a method for replacing a transformer of a wind turbine, wherein a traverse with a first attachment point for attaching a crane hook of a crane and two other attachment points are provided, to which the transformer to be replaced and a balance weight can be posted.
  • a traverse with a first attachment point for attaching a crane hook of a crane and two other attachment points are provided, to which the transformer to be replaced and a balance weight can be posted.
  • To replace the defective transformer to be replaced one end of the traverse is inserted into the door opening of a tower of the wind turbine and the transformer to be replaced is struck at the attachment point.
  • the second end of the truss then projects out of the tower and at the second attachment point a balance weight such as the new transformer can be struck. If the balance weight has substantially the same weight as the generator to be replaced, then the crosshead is maintained substantially balanced and the transformer to be replaced can be lifted out of the door opening.
  • the balance weight may be configured as the new transformer so that the crosshead only needs to be rotated 180 ° and the new transformer can be inserted through the door opening. Then, when the replaced transformer is raised, then it can be achieved that the crosshead is tilted and the new transformer can be transported to its position.
  • the exchange cross-member may be provided with a further first attachment point, so that the crane hook can be coupled to the further first attachment point.
  • This further first attachment point is then not provided in the center of gravity of the exchange crossbar, so that counterweights can be used which do not correspond to the weight of the transformer to be replaced. This is the case, for example, when the new transformer is lighter or heavier than the transformer to be replaced.
  • Fig. 1 shows a schematic representation of a wind turbine with a crane for replacing a transformer of the wind turbine according to a first embodiment.
  • the wind energy plant 100 has a nacelle 110, a rotor 120 with a plurality of rotor blades 130 and a tower 140 with a door opening 150.
  • a transformer 200 is provided in the lower area of the tower 140.
  • a crane 500 is likewise shown, on the crane hook 510 of which a transfer crosspiece 300 is struck.
  • the exchange cross-piece 300 has a first attachment point 310 for receiving a crane hook 510 of the crane 500 and two second attachment points 320 at the first and second ends 321, 322 of the traverse 300.
  • the second attachment points 320 serve to receive a transformer 200 to be exchanged and a balance weight 400.
  • the exchange truss 300 is attached to the first attachment point 310 on a crane hook 510, and a first end 321 of the exchange truss 300 having a second attachment point 320 is inserted through the door opening 150. Subsequently, the transformer 200 may be attached to a second attachment point 320 of the first end 321. At the other second attachment point 320 at the second end 322, a balance weight 400 may be attached. Preferably, the weight of the balance weight 400 is substantially equal to the weight of the transformer 200 to be replaced. Optionally, the new transformer may be used as the balance weight 400.
  • the first end 321 of the exchange truss 300 can first be inserted through the door opening 150 and then tilted, then the transformer 200 can be attached to the second attachment point 320 at the first end 321 and the second end 322 of the crosshead with the balance weight 400 may be tilted so that the transformer 200 may be moved upwardly at the first end 321 and subsequently lifted by the door opening 150.
  • the swivel truss 300 need only be rotated 180 degrees and the new transformer passed through the door opening 150 and the second end 322 of the swap body 300 tilted to bring the transformer 300 into position.
  • a first and / or second pulley 610, 620 may be provided or coupled to the crane hook 510.
  • the first pulley 610 may be coupled to the first attachment point 630.
  • the second pulley 620 may be coupled to the second end 322 of the transfer truss. By the second pulley 620, the second end 322 of the exchange truss 300 can be raised or lowered, so that the exchange truss can be tilted or inclined.
  • the first and second pulley 610, 620 can be connected via a first and second round sling to the first attachment point 310 and the second end 320.
  • the inventive method for replacing a defective transformer can be dispensed with a special crane with a heavy load peak. To replace the defective transformer, only a standard mobile crane is needed.
  • the inventive method for replacing a defective transformer can be used in steel towers, which provide the door opening above the place of use of the transformer.
  • the method according to the invention can also be provided in concrete towers.
  • the inventive method is particularly advantageous if the transformer is provided below the door opening in the tower of the wind turbine.
  • Fig. 2 shows a schematic representation of a exchange crossbar according to a second embodiment.
  • the exchange crossbar according to the second embodiment can be used according to the first embodiment.
  • the exchange crossbar 300 has a first attachment point 310 for receiving a crane hook.
  • the exchange crosshead has at its first and second end in each case a second attachment point 320 for receiving the transformer 200 to be replaced and for receiving a balance weight 400.
  • the exchange crossbar 300 is designed such that it can carry both the weight of the transformer 200 to be replaced and the balance weight 400.
  • FIG. 3 and FIG. 4 show a side view and a plan view of the end of the exchange truss each with a second attachment point 320.
