Abstract
The utility model discloses an it holds intelligent transformer core to have to carry to transfer in the transformer field, including connecting at upper yoke and three stem stems between the indisputable yoke down, the upper yoke is equal with the sectional area of indisputable yoke down, and the sectional area of three stem stems is equal, and the sectional area of upper yoke is greater than the sectional area of stem stem, the utility model discloses it is wide that the sectional area that makes indisputable yoke is greater than the piece of stem stem, realizes the unequal structure in post yoke cross -section, because indisputable yoke cross -section is greater than the stem stem cross -section, the relative stem stem of flux density in the indisputable yoke can reduce, and the loss of indisputable yoke unit kilogram also reduces to under the condition that does not increase stem stem cross -section, wire turn length, winding weight and load loss, the no -load loss of effective control product, thus reduced the use amount of copper product, reduced manufacturing cost, can be used to have carry to transfer and hold in the transformer.
Description
Technical field
This utility model is related to a kind of transformator, particularly to a kind of loaded capacity-regulated transformer.
Background technology
Loaded capacity-regulated intelligent transformer is currently widely applied in power distribution network.User is to loaded capacity-regulated intelligent transformation
The open circuit loss index request more and more higher of device（Originally it is typically S11 type, be all typically now S13 type, open circuit loss substantially drops
Low）, because this product low pressure winding adopts series parallel structure, identical open circuit loss is required and permeability magnetic material, generally has
Carry capacity transfer intelligent transformer iron core ratio common transformer weight, its design magnetic flux density is significantly lower than common transformer.
The stacked distribution transformer of current three-phase all adopts the equal structure in post yoke section（As shown in Fig. 2 being core unshakable in one's determination
Post 2 is identical with the section of upper yoke 1, lower yoke 3）, for meeting the requirement to open circuit loss for the standard, must Synchronous Radio huge pillar yoke section
Long-pending, reduce the magnetic flux density of iron circuit, qualified to guarantee open circuit loss, but winding turn length can be caused to increase simultaneously, lead
Cause copper material consumption to increase and load loss increases.
Utility model content
The purpose of this utility model is to provide a kind of loaded capacity-regulated intelligent transformer unshakable in one's determination, and effective control open circuit loss subtracts
Few copper material usage amount, reduces cost.
The purpose of this utility model is realized in：A kind of loaded capacity-regulated intelligent transformer is unshakable in one's determination, on being connected to
Three stem stems between iron yoke and lower yoke, described upper yoke is equal with the sectional area of lower yoke, the sectional area phase of three stem stems
Sectional area Deng, described upper yoke is more than the sectional area of stem stem.
Compared with prior art, the beneficial effects of the utility model are, this utility model makes the sectional area of iron yoke be more than
The piece width of stem stem, realizes the structure that post yoke section is not waited, because iron yoke section is more than stem stem section, the magnetic flux density phase in iron yoke
Stem stem can be reduced, the loss of iron yoke unit kilogram also reduces, thus not increasing stem stem section, turn length, winding weight
And in the case of load loss, the open circuit loss of effective control product, thus decreasing the usage amount of copper material, reducing and producing into
This.This utility model can be used in loaded capacity-regulated transformer.
For further effective control open circuit loss it is ensured that control effect, the sectional area of described upper yoke is stem stem section
Long-pending 1.05-2 times.
Brief description
Fig. 1 is this utility model structural representation.
Fig. 2 is loaded capacity-regulated intelligent transformer core construction schematic diagram in prior art.
Wherein, 1 upper yoke, 2 stem stems, 3 lower yokes.
Specific embodiment
A kind of loaded capacity-regulated intelligent transformer as shown in Figure 1-2 is unshakable in one's determination, including be connected to upper yoke 1 and lower yoke 3 it
Between three stem stems 2, upper yoke 1 is equal with the sectional area of lower yoke 3, and the sectional area of three stem stems 2 is equal, the cutting of upper yoke 1
Area is 1.05-2 times of stem stem 2 sectional area.
This utility model makes the sectional area of upper yoke 1, lower yoke 3 more than the piece width of stem stem 2, realizes what post yoke section was not waited
Structure, because upper yoke 1, lower yoke 3 section are more than stem stem 2 section, the magnetic flux density in upper yoke 1, lower yoke 3 is relative to stem stem
2 can reduce, and upper yoke 1, the loss of lower yoke 3 unit kilogram also reduce, thus do not increase stem stem 2 section, turn length, around
In the case of group weight and load loss, the open circuit loss of effective control product.
This utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in this utility model, this
The technical staff in field is according to disclosed technology contents it is not necessary to performing creative labour just can be special to some of which technology
Levy and make some replacements and deform, these are replaced and deformation is all in protection domain of the present utility model.
Claims (2)
1. a kind of loaded capacity-regulated intelligent transformer is unshakable in one's determination, and including three stem stems being connected between upper yoke and lower yoke, it is special
Levy and be, described upper yoke is equal with the sectional area of lower yoke, the sectional area of three stem stems is equal, the sectional area of described upper yoke
Sectional area more than stem stem.
2. a kind of loaded capacity-regulated intelligent transformer according to claim 1 unshakable in one's determination it is characterised in that the cutting of described upper yoke
Area is 1.05-2 times of stem stem sectional area.
