Background technology
At present when utilizing wind-force to generate electricity, because separate unit wind power plant own vol is less, the reason that energy output is also relatively less, therefore the needs of electric energy adjustment can be carried out after causing the current electric energy sent wind-driven generator to need the transformer guiding near generating place by wire, this kind of method easily causes wind-driven generator on the one hand, and to export electric energy loss larger, and the drawback of quality of power supply less stable, cause the energy loss of increasing, too increase converting equipment to field occupancy and construction cost on the other hand, and this kind of mode adaptive capacity when generating field ground area is less is poor, as the needs of Oversea wind cannot be met completely, simultaneously, the transformer device structure that the current electric energy for wind power generation adjusts also often relative complex, volume and larger from weight average, and it is simultaneously also relatively poor to the overload protection adaptability of outlet easy in wind power generation, and also there is the deficiencies such as the eddy current loss of increasing, therefore traditional transformer device structure effectively can not meet the needs that wind power generation runs, therefore in the urgent need to developing a kind of novel wind power generation dedicated transformer, with the needs that satisfied reality uses.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of built-in transformer for wind power generation, this novel one side structure is simple, rationally distributed, small in volume, the needs being directly assembled to Wind-driven generator body inside can be met, thus improve wind turbine power generation amount output quality, on the other hand there is good Short Circuit withstand, antijamming capability, electromagnetic eddy loss is little, and the needs of larger current output can be met, thus effectively raise wind power generation for electrical stability and reliability.To achieve these goals, the utility model realizes by the following technical solutions:
A kind of built-in transformer for wind power generation, comprise protective casing, top pressure closure and tap-changing windings, wherein protective casing and top pressure closure form airtight space structure, and top pressure closure upper surface establishes input terminal and outlet terminal, at least one aluminium foil guard screen is separately set and by protective casing inside division as at least two working chambers in protective casing inside, working chamber is distributed in same rectilinear direction, aluminium foil guard screen and protective casing, all connected by insulator between top pressure closure, input terminal and outlet terminal are corresponding with working chamber position respectively, tap-changing windings is positioned at working chamber, tap-changing windings comprises core limb, input winding and output winding, wherein inputting winding is looped around on core limb, and distribute with core limb is concentric, exporting winding is looped around outside input winding, and with input, winding is concentric distributes, input winding and output winding outer surface separately have insulating resin composite protection layer, and separately establish aluminium foil guard screen to isolate between input winding and output winding, input winding and output winding are separately connected with input terminal and outlet terminal respectively, the input terminal of each working chamber and outlet terminal separately connect respectively by bus bar, and the bus bar between adjacent two working chambers separately establishes isolating switch to connect.
Further, described protective casing is the another uniform heating panel in surface.
Further, the input winding in described tap-changing windings is separately connected with inductance coil, and inductance coil distributes around core limb.
Further, insulator is separately established to isolate between described adjacent bus bar.
This novel one side structure is simple, rationally distributed, small in volume, the needs being directly assembled to Wind-driven generator body inside can be met, thus improve wind turbine power generation amount output quality, have good Short Circuit withstand, antijamming capability on the other hand, electromagnetic eddy loss is little, and the needs of larger current output can be met, thus effectively raise wind power generation for electrical stability and reliability.
