The invention relates to a transmission station for feeding locally provided electrical energy, in particular provided by one or more wind power installations, into a grid. According to the invention, it is proposed for a housing of the transmission station to feature a first, accessible room and a second room that is connected to the outside world by means of an exhaust pipe, with such first room and second room being connected to each other by means of a joint recess, with such control unit closing the joint recess, and with one casing of the control unit being open in the area where the recess is closed and/or showing a predetermined breaking point that is adapted to fail if an electric arc occurs inside the control unit.

1. A transmission station for feeding, into a grid, electrical energy generated by a wind power installation the transmission station comprising: a line connection connected to the grid,a control unit having a casing and configured to regulate feeding of the electrical energy, anda lockable housing
1. A transmission station for feeding, into a grid, electrical energy generated by a wind power installation the transmission station comprising: a line connection connected to the grid,a control unit having a casing and configured to regulate feeding of the electrical energy, anda lockable housing that houses the line connection, fasteners and the control unit, wherein: the housing includes a first room and a second room, the second room having a lead-through opening and being connected to an outside environment by an exhaust pipe that is led through the lead-through opening by a flange,the first room and the second room are connected to each other by a joint recess,the control unit closes the joint recess, andthe casing of the control unit having at least one of an opening that is open in an area where the recess is closed and a predetermined breaking point that is adapted to fail when an electric arc occurs inside the control unit. 2. The transmission station according to claim 1, wherein the exhaust pipe is formed by a down pipe with a backlash element, wherein the backlash element is configured to release the down pipe in case of overpressure in the second room. 3. The transmission station according to claim 2, wherein the backlash element is movable back and forth between a locked position and a released position. 4. The transmission station according to claim 2, wherein the backlash element is movable from a locked position to a released position in response to a pressure value being above a threshold value and back to the locked position in response to the pressure value being below the threshold valued. 5. The transmission station according to claim 2, wherein the second room is disposed underneath the first room and separated from the first room by a joint wall. 6. The transmission station according to claim 1, wherein the exhaust pipe extends from the second room into the first room through the lead-through opening and the exhaust pipe extends across the first room leaving the first room through a side or ceiling wall of the housing. 7. A wind farm comprising: one or more wind power installations for generating electrical energy, andone or more transmission stations that are connected to the one or more wind power installations by electrical lines, at least one transmission station of the one or more transmission stations feeding, into a grid, the electrical energy generated by the one or more wind power installations, the at least one transmission station comprising: a line connection connected to the grid,a control unit having a casing and configured to regulate feeding of the electrical energy, anda lockable housing that houses the line connections, fasteners and the control unit, wherein:the housing includes a first room and a second room, the second room having a lead-through opening and being connected to an outside environment by an exhaust pipe that is led through the lead-through opening by a flange,the first room and the second room are connected to each other by a joint recess,the control unit closes the joint recess, andthe casing of the unit has at least one of an opening in an area where the recess is closed and a predetermined breaking point that is adapted to fail when an electric arc occurs inside the control unit. 8. The transmission station according to claim 1, wherein the control unit that is configured to regulate feeding of the electrical energy is further configured to transform the electrical energy and feed-in the transformed energy using the line connection. 9. The transmission station according to claim 1, wherein the lockable housing is weather-proof. 10. The transmission station according to claim 1, wherein the flange is a divisible flange. 11. The transmission station according to claim 4, wherein overpressure in the second room causes the backlash element to move from the locked position to the released position, and a force of gravity or a return element causes the backlash element to move from the released position to the locked position. 12. The wind farm according to claim 7, wherein the exhaust pipe is formed by a down pipe with a backlash element, wherein the backlash element is configured to release the down pipe in case of overpressure in the second room. 13. The wind farm according to claim 12, wherein the backlash element is movable back and forth between a locked position and a released position. 14. The wind farm according to claim 12, wherein the backlash element is movable from a locked position to a released position in response to a pressure value being above a threshold value and back to the locked position in response to the pressure value being below the threshold value. 15. The wind farm according to claim 12, wherein the second room is disposed underneath the first room and separated from the first room by a joint wall. 16. The wind farm according to claim 7, wherein the exhaust pipe extends from the second room into the first room through the lead-through opening and the exhaust pipe extends across the first room leaving the first room through a side or ceiling wall of the housing. 17. The wind farm according to claim 7, wherein the control unit that is configured to regulate feeding of the generated electrical energy is further configured to transform the generated electrical energy and feed-in the transformed energy using the line connection. 18. The wind farm according to claim 7, wherein the lockable housing is weather-proof. 19. The wind farm according to claim 7, wherein the flange is a divisible flange.
