[0003] For example, transformer losses account for a large proportion of power system losses, and reducing transformer losses is of great significance to improving the efficiency of power grid power supply and distribution systems. Amorphous strip core transformers are new energy-saving transformers that use amorphous strips instead of silicon steel sheets as core materials. Compared with silicon steel sheet core transformers, their no-load losses are reduced by more than 70%, and their no-load current is reduced by about 80%. They are currently the most ideal distribution transformers for energy saving.

New research and development exploration is urgently needed in terms of the production of winding equipment, the feasibility and reliability of the forming process method, and winding efficiency.

[0005] In view of this, this patent application is proposed. Utility Model Content

[0028] The technical solution proposed in this application will be described clearly and completely below in conjunction with the above-mentioned drawings. For those skilled in the art, the described embodiments are only part of the solution of this application rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without making creative work should belong to the protection scope of this application.

[0029] Embodiment 1, as Figures 1 to 3 As shown, the present application proposes a novel three-dimensional winding manufacturing equipment for amorphous strips for automated continuous production of three-dimensional winding cores, the equipment comprising a frame structure 1, a large plate 7 vertically arranged on one side of the frame structure 1, two sets of upper material unwinding devices 2 and lower material unwinding devices 3 vertically superimposed and arranged on one horizontal side end of the large plate 7; a set of winding devices 12 is arranged on the other horizontal side end of the large plate 7;

[0030] A set of roller devices 6, a set of floating tension adjustment components 9 and a set of deviation correction devices 11 are arranged in sequence between the upper material unwinding device 2, the lower material unwinding device 3 and the winding device 12;

[0031] Among them, the upper material unwinding device 2 and the lower material unwinding device 3 are respectively used for the material output of a group of amorphous strips; the roller device 6 is used for redirecting the amorphous strip when it is wound; the floating tension adjustment component 9 is used to control the adjustment of the surface tension of the amorphous strip during the winding operation; the deviation correction device 11 is used for the deviation correction and correction of the amorphous strip along the winding axis; the winding device 12 is used for iron core winding.

[0032] An array of roller devices 6 is provided between the upper material unwinding device 2 and the floating tension adjusting assembly 9. The upper amorphous strip 5 extends from the upper material unwinding device 2 through the array of roller devices 6 and then changes direction to wind through the floating tension adjusting assembly 9.

[0033] An array of roller devices 6 is provided between the lower material unwinding device 3 and the floating tension adjusting assembly 9. The lower amorphous strip 8 extends from the lower material unwinding device 3 through the array of roller devices 6 and then changes direction to wind through the floating tension adjusting assembly 9.

[0034] The upper amorphous strip 5 and the lower amorphous strip 8 are bonded to each other at the floating tension adjustment assembly 9 to form a composite double-layer amorphous strip 10;

[0035] A plurality of roller devices 6 are arranged between the floating tension adjustment component 9 and the deviation correction device 11. The composite double-layer amorphous strip 10 extends from the floating tension adjustment component 9 through the roller device 6 and then changes direction and winds through the deviation correction device 11 to perform deviation correction control before winding.

[0036] An array of roller devices 6 is provided between the deflection correcting device 11 and the winding device 12 . The composite double-layer amorphous strip 10 extends from the deflection correcting device 11 , passes through the roller device 6 , and is finally redirected and wound around the winding device 12 .

[0037] The working method of the above-mentioned three-dimensional winding manufacturing equipment for amorphous strips is as follows: the upper amorphous strip 5 extends from the upper material unwinding device 2 through the array of roller devices 6 and then changes direction to be wound through the floating tension adjustment component 9; the lower amorphous strip 8 extends from the lower material unwinding device 3 through the array of roller devices 6 and then changes direction to be wound through the floating tension adjustment component 9; the two layers of strips are bonded to each other at the floating tension adjustment component 9 to form a composite double-layer amorphous strip 10;

[0038] The composite double-layer amorphous strip 10 extends from the floating tension adjustment assembly 9 through the roller device 6 , is redirected and wound through the deviation correction device 11 , and is subjected to deviation correction control before winding, and is finally wound on the winding device 12 .

[0039] The upper material unwinding device 2 and the lower material unwinding device 3 can adopt the following same structural design:

[0040] Taking the upper material unwinding device 2 as an example, the control principle of the double-layer strip before winding is different from that of the correcting device 11. The upper material unwinding device 2 uses the inner edge as a reference to control the entanglement of the single-layer strip before compounding during unwinding, so that the relative positions of the two layers of strip are within the allowable error range during compounding.

[0041] The upper material unwinding device 2 includes two sets of linear guide rails 4 connected in the horizontal direction of the large plate 7, and an unwinding base 28 driven by an unwinding feeding cylinder 20 is slidably connected to the linear guide rails 4. A correction electric cylinder 25, a servo motor 24, and two sets of horizontal and parallel correction linear guide rails 26 are arranged on the unwinding base 28. The unwinding drum 22 for winding and unwinding the upper amorphous strip 5 is axially sleeved and fixed to the support 23 through the unwinding shaft assembly 21. The auxiliary roller 27 is parallel to the axial center of the unwinding drum 22 and is axially fixedly connected to the support 23. The support 23 The bottom is slidably connected to the correcting linear guide 26 through a slider, the servo motor 24 is driven and connected to the unwinding shaft assembly 21 through a synchronous belt and a pulley assembly, and the driving end of the correcting electric cylinder 25 is connected to the support 23; driven by the servo motor 24, the unwinding shaft assembly 21 rotates while driving the unwinding drum 22 to rotate for unwinding; driven by the correcting electric cylinder 25, the support 23 moves back and forth along the correcting linear guide 26 to dynamically adjust the axial distance between the auxiliary roller 27 and the unwinding drum 22 relative to the large plate 7, thereby ensuring that the cutting reference of the upper amorphous strip 5 derived from the unwinding drum 22 is consistent.

[0042] Driven by the unwinding and loading cylinder 20, the unwinding base 28 carrying the components moves back and forth between the loading position I and the unwinding position II along the two sets of linear guide rails 4, thereby completing the cyclic operation process of loading, unwinding, returning and then loading.

[0043] The floating tension adjustment assembly 9 includes a floating roller 14 for winding and redirecting the composite double-layer amorphous strip 10, the bottom of the floating roller 14 is slidably connected to two sets of slide rails 13 arranged in the horizontal direction, one side of the floating roller 14 is horizontally fixedly connected to the driving end of the cylinder 15, and a group of sensors 16 and a proportional valve 17 for adjusting the cylinder pressure to change its horizontal stroke are installed on one side of the cylinder 15;

[0044] Two sets of slide rails 13 are arranged horizontally on the side of the large plate 7, so that the interference effect of their own weight on the surface tension control and feedback sensitivity of the composite double-layer amorphous strip 10 can be reduced accordingly; the sensor 16 is used to detect the position of the floating roller 14 in real time and feed back information to the PLC, and the proportional valve 17 adjusts the internal air pressure of the cylinder 15 according to the position of the floating roller 14 fed back by the sensor 16, thereby adjusting the travel distance of the cylinder 15 to push and pull the floating roller 14 in the lateral direction.

[0045] The function of the floating tension adjustment component 9 is to buffer and compensate for the difference between the unwinding speed of the upper material unwinding device 2 and the lower material unwinding device 3 and the winding speed of the winding device 12. When the difference between the two is larger, the surface tension of the composite double-layer amorphous strip 10 is larger or smaller, which is not conducive to the winding quality of the composite double-layer amorphous strip 10. In this regard, by adjusting the stroke of the cylinder 15 itself, the displacement of the floating roller 14 sliding along the slide rail 13 is adjusted, which eventually causes the angle of the composite double-layer amorphous strip 10 to be wound and redirected by the floating roller 14 to change.

[0046] Based on the structural design and manufacturing process of the above-mentioned amorphous strip three-dimensional winding manufacturing equipment, this embodiment also proposes the following three-dimensional winding core design:

[0047] That is, the three-dimensional wound core is made of double-layer amorphous strip or multi-layer amorphous strip, and is prepared by the above-mentioned amorphous strip three-dimensional winding manufacturing equipment.

[0048] It should be noted that those skilled in the art can also make changes and modifications to the above-mentioned implementations. Therefore, the present application is not limited to the above-mentioned specific implementations, and any obvious improvements, substitutions or modifications made by those skilled in the art on the basis of the present application belong to the protection scope of the present application.

[0049] In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
