Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Figure 1, a kind of iron yoke of the utility model embodiment and the unequal silicon steel transformer fe of stem sectional area
Cored structure, including iron yoke 1 and stem 2；The iron yoke includes iron yoke main and multiple iron yoke secondary groups；The stem includes stem
Main and multiple stem secondary groups；The iron yoke and stem are respectively adopted the layer-by-layer stack of silicon steel sheet and form；The stem secondary group
Including at least 4 secondary groups；The thickness of the iron yoke main is consistent with stem main to the secondary total folded thickness of four-limbed.
Due to the thickness and stem main, the 2nd stem secondary group, the 3rd stem secondary group, the 4th stem secondary group, summation of iron yoke main
Equal, as Figure 2-3, according to the standard of the industry, stem sectional view should fitted ellipse curve.
In the present embodiment, the folded thick total folded thickness for being equal to stem main to 5 grades of the main of iron yoke；The silicon of the iron yoke main
Steel disc width selects most large stretch of width, and generally most large stretch of wide width range is 50-300mm.The iron yoke of other each ranks is secondary
Group is successively successively decreased according to level order.
Further, as Figure 2-3, multiple iron yoke secondary groups are no less than 8；And according to iron yoke main, the 6th grade of iron
Yoke secondary group, the 7th grade of iron yoke secondary group, the 8th grade of iron yoke secondary group, the 9th grade of iron yoke secondary group, the 10th grade of iron yoke secondary group,
11 grades of iron yoke secondary groups, the 12nd grade of iron yoke secondary group are arranged successively assembling；Multiple stem secondary groups are no less than 11, and press
Assembling is arranged successively according to the 2nd grade of stem secondary group to the 12nd grade of stem secondary group.The silicon steel sheet of the iron yoke secondary groups at different levels is wide
Degree is greater than the silicon steel sheet width of the stem secondary group of corresponding level.It should be noted that the iron yoke secondary group and stem of ad eundem
The silicon steel sheet width of secondary group is compared, big 1-2 rank；Such as: the 6th grade of iron yoke secondary group and the 6th grade of stem secondary group
Silicon steel sheet width is compared, big 1-2 rank.
The iron yoke main, each iron yoke secondary group, stem main and each stem secondary group are all made of silicon steel sheet stack
Add.It should be noted that the rank sum of iron yoke secondary group and the rank sum of stem secondary are consistent.
As a result, i.e. when can guarantee identical rank sum, the main of iron yoke is folded thick to be equal to stem main and folds to the 5th grade total
Thick and silicon steel sheet width is most large stretch of width, the silicon steel sheet width of remaining iron yoke at different levels is than the big 1-2 rank of stem, thus reality
The section of existing iron core iron yoke is bigger than the section of core mandrel, smaller than stem by the magnetic flux iron yoke of unit section, i.e. iron yoke
Magnetic flux density is smaller than the magnetic flux density of stem.According to the magnetic flux density and specific loss of orientation silicon steel in professional standard in saturation magnetic
It is linearity curve in logical range, the specific loss of the small corresponding orientation silicon steel of magnetic flux density is small.
The section of iron core iron yoke is bigger than the section of core mandrel, and the specific loss of iron yoke is low, and total losses are also low, to pass through
The loss of iron yoke is reduced to reach the reduction of entire core loss.The transformer of the core structure setting provided through this embodiment
Iron core realizes iron yoke and the unequal silicon steel transformer iron-core structure of stem sectional area；When satisfaction is required with equal loss, reduce
The sectional dimension of core mandrel reduces core window height compared to traditional core structure, reduces iron core phase spacing,
And then transformer integral material dosage is reduced, cost is lower, and energy-saving effect is good.
