Abstract
The utility model discloses a three -dimensional iron core of rolling up of open -core type is mainly formed by the amalgamation unshakable in one's determination of the single frame of three identical rectangle, forms after the munnion limit amalgamation unshakable in one's determination of three single frame and rolls up a three core limb unshakable in one's determination, and horizontal edge forms rolls up an indisputable yoke unshakable in one's determination, and wherein three core limb is that equilateral triangle is three -dimensional to be arranged, is provided with hollow groove structure on every single frame munnion limit unshakable in one's determination and the horizontal edge. The utility model discloses an after the amalgamation unshakable in one's determination of three single frame, respectively in contact with DC power supply, insert the direct current to closed loop unshakable in one's determination is partial, can adjust the change in magnetic field, change no -load loss and load loss.
Description
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of open-core type three dimensional wound core.
Background technology
Reduce discharging the promotion of policy at national energy-saving under, energy saving transformer application is more and more extensive, is just promoted with the gesture of setting a prairie fire.At present, domestic and international most of transformer production producer is the grain orientation cold-reduced silicon sheet by choosing high-quality, increases core lamination thickness, increases copper cash consumption or uses the modes such as high price imported material to reach reduction transformer loss.But resource scarcity is global problem, it is one of difficult problem of facing in recent years of power equipment industry that raw material appreciate, increase material to equal to increase primary energy consumption, this way leaning on many consumable materials or import expensive material to reach reduction transformer loss is worthless.Therefore, the loss that reduce transformer should obtain from structure innovation and technologic improvement.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of open-core type three dimensional wound core, and this three dimensional wound core can effectively reduce core loss and temperature rise.
The utility model is the technical scheme solving the employing of its technical problem:
A kind of open-core type three dimensional wound core, single frame iron core primarily of three identical rectangles is put together, three core limbs of rewinding material are formed after the munnion limit split of three single frame iron cores, transverse frame edge forms the iron yoke of rewinding material, wherein three core limbs are the arrangement of equilateral triangle solid, and the munnion limit of each single frame iron core and transverse frame edge are provided with groove structure.
Further, the groove structure on described munnion limit and transverse frame edge is connected as a single entity, rectangular ring-type.
Further, the cross section of the core limb formed after the munnion limit split of two adjacent single frame iron cores is accurate polygon, and the centre of three core limbs has the vertical through hole formed by the groove structure on the munnion limit of single frame iron core respectively.
Further, the groove structure of three iron yokes can be connected to form a closed loop.
The beneficial effects of the utility model are: a kind of open-core type three-dimensional winding iron that the utility model adopts, the single frame of this open-core type three dimensional wound core is respectively arranged with groove structure, when after the split unshakable in one's determination of three single frames, connect DC power supply respectively, to closed loop portion access direct current unshakable in one's determination, the change in magnetic field can be regulated, change no-load loss and load loss.In addition, groove structure division also plays thermolysis, effectively reduces temperature rise.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model
Fig. 2 is vertical view of the present utility model;
Fig. 3 is the front view of single frame iron core of the present utility model.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of open-core type three dimensional wound core of the present utility model, single frame iron core primarily of three identical rectangles is put together, three core limbs 1 of rewinding material are formed after the munnion limit split of three single frame iron cores, transverse frame edge forms the iron yoke 2 of rewinding material, wherein three core limb 1 solid arrangements in equilateral triangle, the munnion limit of each single frame iron core and transverse frame edge are provided with groove structure 3.
For the form of the groove structure 3 on described munnion limit and transverse frame edge, the utility model does not do specific requirement, and in the present embodiment, the groove structure 3 on described munnion limit and transverse frame edge is connected as a single entity, rectangular ring-type.
In the present embodiment, the cross section of the core limb 1 formed after the munnion limit split of two adjacent single frame iron cores is accurate polygon, and the centre of three core limbs 1 has the vertical through hole 31 formed by the groove structure on the munnion limit of single frame iron core respectively.
In the present embodiment, the groove structure 3 of three iron yokes can be connected to form a closed loop 32.
The open-core type three dimensional wound core that the utility model adopts, its single frame is respectively arranged with groove structure 3, when after the split unshakable in one's determination of three single frames, connect DC power supply respectively, to closed loop portion access direct current unshakable in one's determination, the change in magnetic field can be regulated, change no-load loss and load loss.In addition, hollow parts of the present utility model can also play thermolysis, effectively reduces temperature rise.
The above, just preferred embodiment of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
