Abstract
The utility model discloses a medium and high voltage wind turbine generating set and belongs to the technical field of wind power generation. The medium and high voltage wind turbine generating set comprises a tower cylinder, a wind wheel unit, a cabin and a generator arranged inside the cabin. The medium and high voltage wind turbine generating set is characterized in that the generator is a medium and high voltage generator, and an input shaft of the generator is connected with an output end of a gear case through a coupling. An input end of the gear case is connected with a main shaft through a main bearing, the main shaft is connected with the wind wheel unit, and high voltage transmission cables are arranged from the cabin to the bottom of the tower cylinder. The medium and high voltage wind turbine generating set adopts high voltage cables from the cabin to the bottom of the tower cylinder under the condition that the power is guaranteed, and the number of the cables are reduced and the weight of the cables are lightened, reduces electric energy loss, and at the same time, is beneficial to optimizing the structure of a fan twisted cable system.
Description
Technical field
The invention belongs to technical field of wind power generation, particularly relate to a kind of mesohigh wind power generating set.
Background technique
Wind-power electricity generation market mainstream structural type is cellular structure substantially at present, comprises wind wheel, cabin, tower cylinder etc., and wind wheel directly or indirectly drives the generator amature generating of cabin unit, and the electric energy that again generator is sent arrives at the bottom of the tower by cable transfer.The voltage of generator output is low pressure, and being transported to boosts at the bottom of the tower again is incorporated into the power networks.The shortcoming that this structure exists is that the current ratio of the cable carrying at the bottom of from the tower cylinder to tower is larger, and cable is often heavier, can increase again the weight in cabin and the complexity of layout if transformer is placed into engine room inside.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of wind-powered electricity generation unit of mesohigh generator,
A kind of mesohigh wind power generating set, comprise tower cylinder, wind wheel unit, cabin and place generator in the cabin, described generator is the mesohigh generator, its input shaft is by coupling connection teeth roller box output terminal, the gear-box input end connects main shaft by main bearing, main shaft is connected with the wind wheel unit, the described high voltage electric transmission cable that is provided with from the cabin to tower cylinder bottom.
Described main bearing is one or two, and main bearing is connected by keyboard with gear-box.
Beneficial effect of the present invention:
Adopt structure of the present invention, can be in the guaranteed output situation, the power transmission cable at the bottom of from the cabin to tower adopts high voltage cable, has alleviated number of cables and weight, has reduced electric energy loss, also is conducive to optimize simultaneously the structure that blower fan is turned round the cable system.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the another kind of structural representation of this structure.
Among the figure: 1, wind wheel unit, 11. wind wheels, 2, main shaft, 3, main bearing, 4, gear-box, 5, coupling, 6, generator, 7, the cabin, 71, the cabin underframe, 8, the tower cylinder.
Embodiment
Specifically describe the present invention below in conjunction with drawings and Examples.
Embodiment 1: as shown in Figure 1, be a kind of structural type of the present invention, comprise tower cylinder 8, wind wheel unit 1, cabin 7 and place generator on the cabin underframe 71, described generator 6 is the mesohigh generator, its output shaft is by coupling 5 connection teeth roller boxs 4 input ends, gear-box 4 output terminals connect main shafts 2 by main bearing 3, and main shaft 2 is connected with wind wheel unit 1, and 7 are provided with high voltage electric transmission cable to tower cylinder 8 bottoms from the cabin.
Wind wheel 11 can comprise 1 to 3 piece of blade, wind wheel 11 is connected to main shaft 2 one ends by high-strength bolt, main shaft 2 by be fixed on the cabin underframe 7 one or two main bearing 3 again be connected cabin underframe 7 on gear-box 4 connect by keyboard, gear-box 4 output terminals connect with mesohigh generator on being connected cabin underframe 7 by coupling 5, and whole cabin 7 and wheel hub are connected on the tower cylinder 8 by the bearing on tower cylinder 8 upper flanges.
Embodiment 2: as shown in Figure 2, be another kind of structural type of the present invention.The rotor axle head of directly being connected with the mesohigh generator in its wind wheel unit 1 connects by high-strength bolt, mesohigh generator 6 is fixed on the cabin underframe 7 by high-strength bolt, cabin underframe 7 is fixed on above the tower cylinder 8 by the bearing on tower cylinder 8 upper flanges again, and 7 are provided with high voltage electric transmission cable to tower cylinder 8 bottoms from the cabin.
Main bearing among the present invention and locking plate are existing conventional structure, do not repeat them here.
Working principle of the present invention:
During fan operation, wind wheel 11 drives generators 6 rotors, and generator 6 is directly exported mesohigh electric power, be delivered directly to tower by high voltage cable from cabin 7 at the bottom of.So namely alleviate number of cables and weight, reduced again electric energy loss, also be conducive to optimize simultaneously the structure that blower fan is turned round the cable system.
