Abstract
The utility model provides a three-core column trapezoidal surrounding iron core, comprising an inner iron core containing a middle core column and side columns. An outer iron core containing the side columns is coated out of the inner iron core, and every two side columns of the outer iron core and the inner iron core are connected together to form two side core columns. The utility model is characterized in that the circumferential surfaces of the middle core column and the two side core columns form a staircase shape, and the utility model can be made into a transformer with various purposes via sheathing three special coil frames or winding coils through a special winder after special technical processing.
Description
The utility model provides a kind of transformer core, the trapezoidal wound core of particularly a kind of three stem stems.
Defectives such as at present, the three stem stem transformer cores that electric power system is used are that seam and mitre structure are arranged, so there is leakage field inevitably in iron core, and the big and iron loss of magnetic resistance is big.The diameter of iron core column have to be increased in order to reduce iron loss, but so long increasing of average turn of having caused coil again, the internal resistance of coil increases, and copper loss is big, temperature height, the big deficiency that waits of distributed capacitance.China No. 93238611.3 patent disclosures a kind of " 8 " word three stem stem seamless iron cores, comprise the interior iron core that contains stem stem and semicircle side column in the circle, interior iron core is outside equipped with the outer iron core that contains the semicircle side column, the semicircle side column of outer iron core and interior iron core in twos mutually ground connection form two round edge stem stems, because the cross section of middle stem stem and both sides stem stem is rounded, therefore reel inside and outside iron core sunset steel band two planes and two sides out of plumb, bring very big difficulty to processing.
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of improved trapezoidal wound core of three stem stems that can replace traditional seam and the stacked three stem stem iron cores of mitre is provided.
The utility model provides a kind of three stem stems trapezoidal wound core, it comprises the interior iron core that contains middle stem stem and side column, interior iron core is coated with the outer iron core that contains side column, outer iron core and interior iron core side column in twos mutually ground connection form the both sides stem stem, the side face of stem stem and both sides stem stem is stairstepping in of the present utility model being characterised in that.The utility model puts three special coil racks of making or uses special-purpose coil winding machine coiling after special PROCESS FOR TREATMENT, promptly can be made into the transformer of various uses.
Iron core and outer iron core are continuous reeling shape in above-mentioned, make seamless iron core thus.
Iron core comprises two convex formulas " O " sections core in above-mentioned, and the left and right side column phase ground connection of two convex formula " O " sections cores connects as one, the approximate half-circular of the cross section of convex formula " O " sections core for increasing progressively successively by sheet.
Above-mentioned outer iron core is raised type " O " sections core, the approximate half-circular of the cross section of raised type " O " sections core for successively decreasing successively by sheet.
The utility model adopts thickness δ=0.5mm or following silicon steel sheet or other high permeability material, determine to cut across out the different band material of various width with cutting across machine according to the size of iron core column, re-use the continuous from narrow to wide coiling of annular roller and go out two convex formulas " O " sections core, again the left side of two convex formulas " O " sections core, the right post phase ground connection be combined into one contain in stem stem and side column interior iron core again in interior iron core external application by wide to narrow silicon steel sheet band material continuous reeling, two stem stem coileds up to both sides, fixed the tail point solid welding, the trapezoidal wound core of three stem stems just made (Fig. 1, Fig. 2).Iron core by special processing after, adopt special-purpose coil winding machine coiling, just can make the transformer of various uses.
The utility model with existing three stem stem seams, the mitre laminated core structure is compared has following characteristics:
The utility model adopt keystone ring around, utilize trapezoidal rectilinear clearance, make transformer oil or the air can convection current, solved the heat dissipation problem of iron core and coil.
2. because silicon steel sheet is to be cut into straight line band material, the utilance of silicon steel sheet is 100%.
3. because the utility model does not cut, no gaping of joints has fundamentally been eliminated leakage field, and because the noise that cutting causes after merging, reduced magnetic resistance and iron loss, its iron loss is approximately 50% of S7 type power transformer, and no-load current is 30% of a S7 type power transformer.Because iron core is whole, its overload capacity has the seam iron core incomparable, therefore can make high-quality, high energy-conservation any transformer.
4. appearance of the present utility model, a major progress for world today's power transformer and electronic transformer, it is with novel, particular structure, can substitute the stacked three stem stem iron cores of traditional seam and mitre fully, its superiority is that traditional seam and mitre laminated core structure is incomparable.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the cutaway view of Fig. 2 along the A-A section.
Fig. 2 is the cutaway view of Fig. 1 along the B-B section.
With reference to figure 1～Fig. 2, the utility model comprises the interior iron core that contains middle stem stem and side column, interior iron core is coated with the outer iron core 1 that contains side column, interior iron core comprises that the left and right side column phase ground connection of convex formula " O " sections core 2,3, two convex formula " O " the sections cores 2,3 of two continuous reeling shapes that employing straight sunset steel band material from narrow to wide turns to continuously connects as one.Outer iron core 1 is for by wide raised type " O " sections core to narrow straight sunset continuous reeling shape turning to continuously of steel band material, two side columns of two side columns of raised type " O " sections core 1 and two convex formula " O " sections cores 2,3 connect as one with joining, form the trapezoidal wound core of three stem stems that contains middle stem stem 4 and limit stem stem 5,6 thus.The approximate half-circular of the cross section of above-mentioned convex formula " O " sections core for successively decreasing successively by sheet.The approximate half-circular of the cross section of above-mentioned raised type " O " sections core for successively decreasing successively by sheet.
