Abstract
The utility model discloses a dry-type transformer specially used for offshore wind power generation. The transformer is a Dyn11 coupling group connected by three single-phase transformers through an external bus. Each single-phase transformer comprises a single-phase two-column iron core and a low-voltage foil-winding coil and a high-voltage coil respectively wound on the outer layer of the iron core. A coil strut is arranged between the iron core and the low-voltage foil-winding coil. A polyesterimide glass fabric barrel is arranged between the high-voltage coil and the low-voltage foil-winding coil. With simple and suitable structure and safe and reliably performance, the dry-type transformer specially used for offshore wind power generation is installed and maintained conveniently at the inner part of the wind turbine tower.
Description
Technical field
The utility model relates to a kind of Oversea wind power generation transformer.
Background technology
National energy general bureau spells out in working energy general requirement in 2010 and task: 2010, continue to advance large-scale wind electricity construction of base, particularly offshore wind farm to carry out.This shows that national large-scale development offshore wind farm will manifest effect this year.On January 22nd, 2010, country's issue≤offshore wind farm development ﹠ construction management temporary method 〉=, indicate that national energy general bureau begins to strengthen the management of offshore wind farm exploitation, has started first batch of offshore wind farm royalty right project simultaneously.According to above information analysis, adopt the special-purpose dry-type transformer of Oversea wind power generation imperative.
For the offshore wind farm dry-type transformer, the blower fan tower barrel inlet that transformer is installed is less, but requires transformer to have characteristics such as capacity is big, anticorrosion, protection from fumes corrosion, also requires it can make things convenient for turnover blower fan, installation, dismounting and safety to change.
Summary of the invention
For satisfying the above-mentioned requirements of Oversea wind power generation to transformer, the utility model provides Oversea wind power generation special-purpose dry-type transformer, and its technical scheme of taking is:
The Dyn11 joint group of this transformer for connecting into by outside busbar by three single-phase transformers.
Each single-phase transformer comprises single phase two limb core and respectively around outer field low blocking coiling of iron core and high-tension coil, be provided with coil stay between the unshakable in one's determination and low blocking coiling, be provided with polyester-imide glass cloth tube between high-tension coil and the low blocking coiling.
This utility model adopts three separate single-phase transformers, being connected to become connection set by external electrical is Dyn11, this provides very big convenience for the blower fan tower barrel internal transformer is installed, overhauled, safety is changed, solved transportation difficult, install difficult and safeguard difficult problem.Characteristics such as transformer material adopts anti-corrosion insulation material and high-quality anti-corrosion resin, has anticorrosion, protection from fumes, and is aesthetic in appearance.
Therefore the utility model is simple and practical, and performance is safe and reliable, and working service is convenient, saves production cost and user's maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, three identical single-phase transformers 1 of structure are connected to become the special-purpose dry-type transformer of three-phase offshore wind farm that connection set is Dyn11 by outside busbar 9.
As shown in Figures 2 and 3, low blocking coiling 4 and high-tension coil 6 are respectively around the skin of single phase two limb core 2, coil stay 5 is supported between iron core 2 and the low blocking coiling 4, and polyester-imide glass cloth tube 7 is clipped between high-tension coil 6 and the low blocking coiling 4.The upper and lower of single-phase transformer 1 is fixed with folder 8, is provided with cushion block 3 between folder 8 and high-tension coil 6 and the low blocking coiling 4.
The utility model can resolve into three-phase transformer 3 independent single-phase transformers, has made things convenient for user's transportation, installation, dismounting at the scene.If single-phase breaking down can be changed separately, this provides convenience for the client, has saved cost.
Claims (2)
1. the special-purpose dry-type transformer of Oversea wind power generation is characterized in that the Dyn11 joint group of this transformer for being connected into by outside busbar (9) by three single-phase transformers (1).
