Abstract
The invention relates to a three-phase dry-type transformer for wind power generation, comprising coils with different phases and iron cores (5). The wind power generation three-phase dry-type transformer is characterized in that the coils in different phases respectively comprise an inner low-pressure coil (4) and an outer high-pressure coil (3) which are concentrically sleeved on an iron core (5); the same alternative separator (6) structure is used between every two adjacent high-pressure coils (3); a yoke separator (2) structure is used between a high-pressure coil (3) and an iron core yoke; two steel-plate transformer bases (7) are mounted at the bottom of the transformer; and a transformer hanger plate (1) extends out of an outer shell. Compared with a common power dry-type transformer with the same capacity and the same model, the three-phase dry-type transformer for wind power generation has the advantages of small size, low cost and excellent performance and can be integratedwith a high-low voltage switch cabinet and other control equipment and mounted in a wind tower so as to directly finish power generation to transmission in the wind tower, replace an original box-typetransformer substation outside the wind tower and decrease the equipment investment.
Description
Affiliated technical field
The utility model relates to a kind of three-phase dry-type transformer for wind power generation, exactly is a kind of three-phase dry-type transformer for wind power generation that can be installed in the wind tower, belongs to electrical equipment technical field.
Background technology
Wind power generation transformer of the prior art, the general employing on wind tower next door installed a box-type substation structure in addition again, box-type substation structure fabrication cost height, complex structure, take up room big.The installed capacity of wind power generation at present constantly increases, and the output voltage of generating set has reached 20kV and 35kV electric pressure, and the box-type substation cost is increased, and structure is more complicated, and it is bigger to take up room.
Summary of the invention
The utility model solves wind power generation and on wind tower next door a box-type substation is installed in addition again, and box-type substation cost of manufacture height, complex structure, big problem takes up room.Purpose provides a kind of three-phase dry-type transformer for wind power generation that can be installed in the wind tower.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of three-phase dry-type transformer for wind power generation, comprise each phase coil and iron core, it is characterized in that: described each phase coil comprises that internal layer is a low-voltage coil, skin is a high-tension coil, inside and outside layer line circle concentric locking collar is contained on the iron core, use inter-phase splitter plate construction between two adjacent high-tension coils, use heel piece splitter plate construction between high-tension coil and iron core yoke, two block plate transformer bases are installed in described transformer bottom.The transformer boatswain chair stretches out shell.
This wind power generation dry-type transformer is compared with the common electric power dry-type transformer with the capacity same model, volume is little, cost is low, superior performance, directly be installed in the wind tower after can be with high and low pressure switch cubicle and other control appliances integrated, transmit electricity from generating electricity to and directly in the wind tower, to finish, replace former box-type substation outside the wind tower, reduced equipment investment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure chart of three-phase dry-type transformer for wind power generation.
Among the figure: 1. transformer boatswain chair, 2. yoke dividing plate, 3. high-tension coil, 4. low-voltage coil, 5. iron core, 6. phase partition, 7. transformer base.
Embodiment
A kind of three-phase dry-type transformer for wind power generation, comprise each phase coil and iron core 5, it is characterized in that: described each phase coil comprises that internal layer is a low-voltage coil 4, skin is a high-tension coil 3, inside and outside layer line circle concentric locking collar is contained on the iron core 5, use phase partition 6 structures between two adjacent high-tension coils 3, use yoke dividing plate 2 structures between high-tension coil and iron core yoke, two block plate transformer bases 7 are installed in described transformer bottom.Transformer boatswain chair 1 stretches out shell.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
Claims (2)
