Abstract

A transformer station, in particular, an offshore transformer station including at least one transformer and at least one transformer cooling unit arranged on at least one side wall of the transformer station or a roof of the transformer station and configured to cool the at least one transformer. The transformer station also includes at least one air deflecting unit arranged on at least one roof edge of the transformer station and/or at least one air deflecting unit arranged on at least one side edge of the transformer station. The air deflecting unit is arranged such that an air movement is deflectable in the direction of the transformer cooling unit.

Claims

1. An offshore transformer station, comprising:

at least one transformer,

at least one transformer cooling unit arranged on at least one side wall of the transformer station or a roof of the transformer station and configured to cool the at least one transformer,

at least one of at least one air deflecting unit arranged on at least one roof edge, in which a vertical wall meets a horizontal wall, of the transformer station or at least one air deflecting unit arranged on at least one side edge, in which a first vertical wall meets a further vertical wall, of the transformer station,

wherein the air deflecting unit is arranged such that an air movement is steerable in the direction of the transformer cooling unit.

2. The transformer station according to claim 1, wherein the air deflecting unit comprises at least one flat air deflecting element,

wherein the air deflecting element comprises, a planar side profile or a curved side profile.

3. The transformer station according to claim 2, wherein at least one connecting element is provided in order to fix the air deflecting unit in an area of the at least one roof edge or the at least one side edge, the at least one connecting element being formed in such a way that there is a minimum distance of at least 0.1 m between the air deflecting unit and the corresponding roof edge or side edge.

4. The transformer station according to claim 2, wherein the air deflecting unit comprises at least one actuator operatively connected to the air deflecting element,

wherein the actuator is configured to move the air deflecting element between at least a first position and a further position.

5. The transformer station according to claim 4, wherein the transformer station comprises at least one control unit configured to control the actuator,

wherein the control unit is configured to control the actuator depending on at least one provided meteorological parameter.

6. The transformer station according to claim 5, wherein the at least one meteorological parameter at least one of is a wind speed, a wind direction, an air humidity, an ambient temperature or a solar radiation.

7. The transformer station according to claim 1, wherein the transformer station further comprises:

at least one measuring unit configured to measure at least one parameter relevant to a temperature of the transformer, and

at least one control device at least configured to control a current fed into the transformer at least depending on the measured parameter.

8. The transformer station according to claim 7, wherein the at least one measured parameter is at least one of is the temperature of the transformer or a meteorological parameter comprising at least one of a wind speed, a wind direction, an air humidity, an ambient temperature or a solar radiation.

9. The transformer station according to claim 7, wherein the transformer station comprises at least one further transformer,

wherein the measuring unit is configured to measure at least one parameter relevant to a temperature of the further transformer, and

wherein the control device is configured at least to control a current fed into the further transformer at least depending on the measured parameters of the at least two transformers.

10. An apparatus for the transformer station with the at least one transformer, the transformer station according to claim 1, the apparatus comprising:

at least one measuring unit configured to measure at least one parameter relevant to a temperature of the transformer, wherein the measured parameter is a meteorological parameter comprising at least of a wind speed or a wind direction, and

at least one control device at least configured to control a current fed into the transformer depending on the measured parameter.
