Description
Technical field
The wind-driven generator of atop a tower flexible suspension transformer described in the utility model, is related to a kind of wind-driven generator
Transformer flexible installing structure.
Background technology
As the installed capacity of Wind turbines is increasing, transformer as the important electrical equipment of blower fan, its volume and
Weight is consequently increased.How transformer is reasonably arranged, be the factor that overall design needs emphasis to consider.Most of blower fans
Transformer facilitates ground staff to overhaul to be built in tower bottom or being placed on tower outside ground, but transformer is away from generating
Machine, inevitably in the presence of some drawbacks：On the one hand, generator is more long to step down side cable, and line loss is larger, for a long time into
This is higher, is estimated according to expert, by taking 2 megawatts of blower fans as an example, the power transmission cable in whole tower height, in 20 years life of blower fan
In cycle, 35kV high voltage power transmissions are compared with 690V transmissions of electricity, to increase the equivalent economic worth of line loss up to more than million yuan.Second party
Face, is built in the transformer of bottom of towe, it is necessary to single cooling system.3rd, the transformer being placed in outside tower is, it is necessary to additionally build
If basis or platform, increased blower fan floor space and cost.
Also there are a small number of blower fans that transformer is placed in cabin at present, not only shorten the low pressure between generator and transformer
Cable length, reduces line loss, and can utilize the cooling system of cabin and no longer need to be separately provided cooling system, but
This can dramatically increase the volume of cabin, and natively compact Arrangement of Engine-room is made troubles.
Megawatt fan, tower top height is more in even more than hundred meters of tens of rice.Up to a hundred tons of blower fan when tower top runs, meeting
Cause the frequency wobbles of tower top, this stability and fatigue life to unit is all adversely affected.It is this unfavorable to reduce as far as possible
Influence, avoids in addition to impeller and tower resonance, it is also desirable to consider how to increase certain damping, to reduce tower top when in design
Oscillating quantity.
For it is above-mentioned the problems of in the prior art, a kind of new atop a tower flexible suspension transformation of research and design
The wind-driven generator of device, is the problems of in the prior art very necessary so as to overcome.
The content of the invention
In view of it is above-mentioned the problems of in the prior art, the purpose of this utility model is a kind of new tower of research and design
The wind-driven generator of cylinder top flexible suspension transformer.It is used to solve following point present in prior art：1st, transformer is put
In bottom of towe, type low-voltage cable is more long, increased kwh loss, accumulates over a long period and causes great economic loss；2nd, transformer is placed in tower
Bottom is, it is necessary to single cooling system, increased cost of investment and maintenance cost；3rd, transformer is placed in tower outside, it is necessary to extra
Foundation construction platform and protective equipment, increased the floor space and investment maintenance cost of blower fan；4th, transformer is installed on cabin
It is interior, cabin volumes are dramatically increased, it is unfavorable for cabin compact Layout；5th, during fan operation the frequency wobbles of tower top to the stabilization of unit
Property and life-span adversely affect, and should try to weaken this swing.The arrangement of above-mentioned existing transformer, does not all reach decrease tower top pendulum
Dynamic purpose.
What technical solution of the present utility model was realized in：
The characteristics of the utility model, is mainly the change of transformer mounting means, is changed to be flexibility by existing being rigidly connected
Suspension, is changed to be arranged in tower top by arrangement in existing bottom of towe or cabin, to realize reducing tower body shaking degree, increases blower fan steady
Qualitatively effect.
The wind-driven generator of atop a tower flexible suspension transformer described in the utility model, including cabin, mainframe, change

Rush between layer and leave gap.Suspended in midair because transformer is flexible, it can allow relative displacement between tower, when blower fan is on tower top
When end produces swing, the gap allows transformer to have making contact with cushion, suspends the inertia damping effect of transformer in midair,
Tower top swing can be weakened.
Through-hole structure is left in the middle of transformer described in the utility model；Through hole is left on mainframe base plate；Between crossbeam
Also enough spaces are left to be easy to supply personnel upper and lower；Gap between through-hole structure and transformer and tower, forms cooling
The passage of air-flow.
Transformer described in the utility model use air natural cooling when, the cooling system row fan formula heat exchanger to
Outside cabin during air draft, upward air-flow is formed in tower, exactly used by transformer Cooling.If transformer uses water-cooled, transformation
The cooling line of device itself is parallel in cooling system by flexible pipe, it is not necessary to single transformer water-cooling system.
Mainframe bottom described in the utility model and transformer top are provided with hanger；Hoist cable two ends carry U-shaped button；With
U-shaped button connects hanger；Hoist cable 20 is that round-link chain, steel wire rope etc. can carry rope, and rope number is at least 3；Mainframe base plate
There must be enough intensity, because the moment of flexure that not only transmission wind load is brought, still suffers from the gravity of transformer.
Crossbeam described in the utility model is at least two, and crossbeam can be connected with or the mode welded is fixed on tower top
On inwall；The bottom of crossbeam and transformer top are provided with hanger；Hoist cable two ends carry U-shaped button；Hanger is connected with U-shaped button；Hang
Rope quantity is at least 3.
The utility model has the advantages that it will be apparent that being mainly manifested in：
1st, blower fan described in the utility model, it is used using transformer using transformer built-in tower top and the structure of flexible suspension
Property and the contact-impact between tower, tower top is swung and produces certain damping action, reduce shaking degree, be conducive to wind
The stable operation of machine.
2nd, the transformer is close apart from generator, and step down side only needs to very short low-voltage cable, and passes through and become
Transmission of electricity is high voltage power transmission in whole tower altitude range after depressor boosting, and tower bottom is placed in away from generator compared to transformer
Arrangement, can significantly reduce line loss, with long-term economics value.
3rd, the transformer built-in, compared to tower inner bottom part or outside ground is placed in, saves soil in atop a tower
Build the expense of basis or mounting platform；Compared to the arrangement for being built in cabin, installing space is saved, reduces cabin size,
Be conducive to cabin minimize, it is integrated.
4th, using the cooling system of cabin, it is not necessary to set independent cooling system.
There is the utility model strong structure novelty, simple processing, easy to assembly, stability, reduce loss, reduction to invest into
The advantages of sheet and maintenance cost, it in high volume puts goods on the market will produce positive social benefit and significant economic benefit.
