Abstract

The invention relates to a wind power plant having a tower that has at least one bottom tower segment and a pre-manufactured fire protection module for fireproof receiving of a transformer. The fire protection module is placed within the bottom tower segment.

First claim

The invention claimed is:

1. A wind power installation comprising:
a pylon having a lower pylon segment;
a precast concrete fire protection module located within the lower pylon segment;
a transformer transport securing system in the fire protection module; and
a transformer located within the fire protection module, the fire protection module being configured to protect the transformer during a fire, the transformer transport securing system coupling the transformer to the fire protection module, wherein the transformer transport securing system secures the transformer during a transport of the precast concrete fire protection module and the transformer into the lower pylon segment.

2. The wind power installation according to claim 1 wherein the fire protection module has a first opening for the transformer to pass through and a second opening for service personnel to pass through.

3. The wind power installation according to claim 1 wherein the fire protection module has at least one fire protection termination means for at least one of electric cables and an electric bus bar system to extend through.

4. The wind power installation according to claim 1 wherein the fire protection module has a transformer transport rail system.

5. The wind power installation according to claim 3 wherein at least one of the electric cables and the electric bus bar system are passed through the fire protection termination means and the fire protection termination means has a fire protection casting sealant comprising a thermally insulating material.

6. The wind power installation according to claim 1 wherein a passage is provided between the interior of the fire protection module and an opening in a wall of the lower pylon segment for reducing pressure within the fire protection module.

7. The wind power installation according to claim 5 wherein the fire protection module is thermally decoupled from the lower pylon segment.

8. The wind power installation according to claim 5 wherein the thermally insulating material assists in thermally decoupling the fire protection module from the lower pylon segment.

9. A method comprising:
placing a transformer in a fire protection module;
securing the transformer to the fire protection module; and
while the transformer is secured to the fire protection module, transporting the fire protection module and the transformer into a lower pylon segment of a wind power installation.

10. The method according to claim 9 wherein the fire protection module is made of concrete.

11. The method according to claim 9 wherein transporting comprises moving the fire protection module along guide rails that extend into the lower pylon segment of the wind power installation.
