Description
Technical field
The present invention relates to the raisings of the cooling performance of oil-immersed transformer used in sea-borne wind power generation apparatus.
Background technique
Using as the wind-power electricity generation of natural energy resources, functionization is able to as the application method beneficial to earth environment.It should
Wind-power electricity generation has in the setting of the lands such as mountain forest and is at sea arranged.In particular, not to the soil for being suitable for being arranged windmill
Limitation, compared with land wind speed faster and the disorder of wind also less Oversea wind power generation is expected.
In addition, in the electric power that conveying is generated electricity with sea-borne wind power generation apparatus, when for safety and inhibiting transmission of electricity
Loss purpose, it is desirable that boost to the obtained voltage of power generation to convey, thus, it is desirable that at sea in wind power generation plant
Transformer is set.On the other hand, at sea in the tower of wind power generation plant when setting transformer, heat source increases, in tower
Temperature rises.Because being arranged in closed tower, cooling condition when outdoor setting compared with deteriorate, thus cooling performance
Raising become requirement.Therefore, it is necessary to carry out the pressure using fan etc. to be sufficiently carried out cooling down for transformer
It is cooling.
On the other hand, Japanese Unexamined Patent Publication 2011- can be enumerated about the cooling means of the heat source of sea-borne wind power generation apparatus
Technology disclosed in No. 89468 bulletins (patent document 1).In patent document 1, describe by absorbing water secondary cell configuration
The lower section of line makes the technology discharged with the heat of the secondary cell of charge and discharge into water.
Existing technical literature

Specific embodiment
Hereinafter, with Detailed description of the invention embodiment.
Embodiment 1
Fig. 1 is the structural outline figure of sea-borne wind power generation apparatus.In Fig. 1,1 is sea-borne wind power generation apparatus entirety, and 2 be leaf
Piece, 3 be cabin, and 4 be generator, and 5 be tower, and 6 be sea, and 7 be transformer, and 8 be power transmission cable.
Tower 5 is hollow structural body, is equipped with cabin 3 on the top of tower 5.Blade 2 and cabin 3 link, blade 2 because
Wind-force and when rotating, generate AC power by configuring the generator 4 in cabin 3, will by configuring the transformer 7 in tower 5
Electric power boosting, and conveyed with power transmission cable 8.The reasons why being boosted with transformer is because by making voltage raising can be by electric current
It is suppressed to lower, safely transmits electricity so being converted to low current, and in order to inhibit loss when transmission of electricity by low current value.
Fig. 2 indicates the whole synoptic diagram of the sea-borne wind power generation apparatus of the present embodiment.In addition, Fig. 3 indicates the present embodiment
The detailed maps of sea-borne wind power generation apparatus.In Fig. 2,9 be seawater, and the tower of wind power generation plant at sea is arranged in transformer 7
Below sea in cylinder 5.In addition, 7-2 is coil in Fig. 3,7-3 is iron core, is full of for the iron core and coil to be accommodated in
Transformer 7 in the cabinet 7-1 of insulating oil (not shown) for insulating and cooling down, the knot that is immersed in liquid 10
Structure.That is, using the liquid storage portion for the accumulation liquid that setting is constituted using the wall surface of tower in tower 5, in the liquid storage
Portion's setting has the transformer of cabinet, by the structure of cabinet dipping in a liquid.
Fig. 4 shows the sectional view 4 (A) and its side view 4 (B) when the transformer portion of Fig. 3 from side surface upper part.Figure
In 4,7-4 is insulating oil, and 7-5 is radiator, and 7-6 is pasta line, other numbers have with it is attached shown in the figure that has been described above
The identical function of the structure of the same symbol is added, and the description is omitted.
In Fig. 4 (A), it is configured to improve between the seawater 9 of the periphery of tower and impregnating cabinet 7-1 with liquid 10
Thermal conductivity improves cooling effect.Wherein, liquid 10 is the liquid of transmitting heat, such as can be pure water.
In addition, radiator 7-5 can be connected to via the upper opening and lower openings of cabinet 7-1 in cabinet in Fig. 4 (B)
Ground connection, the intracorporal insulating oil 7-4 of case are recycled in radiator, are radiated by the insulating oil after the intracorporal coil 7-2 heating of case
Device is cooling and returns to cabinet, so as to further increase cooling performance.
In this way, the cooling device miniaturization of transformer itself can be made by the cooling performance for improving transformer.In addition, not
The equipment for keeping sea-borne wind power generation apparatus cooling is needed, can be realized the miniaturization of sea-borne wind power generation apparatus itself.
In addition, by making liquid 10 be dipped into the primary heat source i.e. height of coil 7-2 of transformer 7, it is easier to Absorption Line
The heat of circle, it is not required that cabinet is all full of by liquid 10, for example, pasta line 7-6 or less, coil by making insulating oil
It more than the height of 7-2 immerses in liquid 10, cooling effect can be obtained.For example, submerging hachure shown in Fig. 4 (B) with liquid 10
The part shown.In this way, being configured to using the cabinet that oil-immersed transformer is arranged originally, with the week of liquid-immersed cabinet
It encloses, so that cooling effect is improved, so having the effect of without applying waterproof processing in a liquid and newly to impregnate.In addition,
By further implementing the antirusts countermeasure such as coating, can be used for a long time.
In this way, the present embodiment is realized the such oil immersion in a liquid of the cabinet being arranged as oil-immersed transformer dipping
The raising of the distinctive cooling performance of formula transformer.
As mentioned above, according to the present embodiment, by improving oil immersed type transformation used in sea-borne wind power generation apparatus
The cooling performance of device can be realized the miniaturization of the cooling equipment of oil-immersed transformer itself.Furthermore, it is not necessary that for making sea
The cooling equipment of wind power generation plant, can be realized the miniaturization of sea-borne wind power generation apparatus itself.It is further possible to solve be
It is cooling and in the case where using fan, imported from fan containing moisture, salinity because such environment is at sea arranged
Wind, so transformer is easy to the problem of getting rusty.
【Embodiment 2】
Fig. 5 indicates the schematic diagram of the sea-borne wind power generation apparatus of the present embodiment.The present embodiment is removal oil-immersed transformer
Cabinet, using sea-borne wind power generation apparatus tower 5 wall surface replace cabinet without box structure.
