Abstract

A transformer chamber for a wind turbine is described. The transformer chamber includes a liquid-tight tank for receiving a liquid-filled, in particular oil-filled, transformer, a wind turbine structure component includes a component bedframe adapted for receiving such a transformer chamber and a wind turbine includes such a transformer chamber and such a wind turbine structure component. Furthermore, a method for assembling a wind turbine is described.

First claim

The invention claimed is:

1. A wind turbine, comprising:
a rotor;
a nacelle connected to the rotor, wherein the nacelle comprising a component bedframe adapted for receiving a transformer chamber;
the transformer chamber comprising a liquid-tight tank including an oil-filled transformer and support rails for attaching the transformer chamber to the component bedframe;
wherein the transformer chamber is detachably connected to the component bedframe;
wherein the liquid-tight tank is an explosion safe tank and comprising an explosion plate having a predetermined breaking point and a first opening located along a bottom section of the explosion plate, wherein a bending section of the explosion plate is created with parallel running slits at the first opening; and
wherein a plurality of bolts are located along the bottom section of the explosion plate parallel to the first opening and deformation bolts hold an upper section of the explosion plate to the transformer chamber, wherein in case of an explosion, the deformation bolts and the explosion plate bends outwardly along the bending section.

2. The wind turbine according to claim 1 ,
wherein the oil-filled transformer including low voltage terminals and high voltage terminals, and
wherein the low voltage terminals and the high voltage terminals being accessible from a top surface of the transformer chamber.

3. The a wind turbine according to claim 1 ,
wherein the explosion plate is made from aluminum.

4. The wind turbine according to claim 1 , comprising:
a cooling channel system.

5. The wind turbine according to claim 1 , comprising:
a hatch.

6. The wind turbine according to claim 1 , comprising:
a cooling air inlet and a cooling air outlet adapted to provide a cooling air path in the transformer chamber.

7. The wind turbine according to claim 6 , comprising:
a fan.

8. The wind turbine according to claim 1 ,
wherein the transformer chamber is movable relative to the component bedframe.

9. The wind turbine according to claim 1 ,
wherein the transformer chamber is movable in a direction of gravity when the transformer chamber is detached from the component bedframe.

10. The wind turbine according to claim 1 , wherein the transformer chamber further comprises an oil pit.

11. The wind turbine according to claim 1 , wherein the transformer chamber further comprises support beams.
