Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, and particularly relates to an integrated machine for winding high-voltage and low-voltage coils of a transformer. Background Art

[0002] A transformer is an electrical device used to change the AC voltage, usually including one or more windings and an iron core. Through the transformer, the voltage can be transferred from one circuit to another while changing the magnitude of the voltage. A three-winding transformer is a type of transformer. Each phase of the three-winding transformer has three windings, and the high, medium, and low-voltage windings of each phase are all sleeved on the same iron core column; when one winding is connected to an AC power supply, different electromotive forces are induced in the other two windings. This type of transformer is used for loads that require two different voltage levels. Three different voltage levels usually appear in power plants and substations, so three-winding transformers are widely used in the power system.

[0003] The high-voltage coil winding, medium-voltage coil winding, and low-voltage coil winding in the three-winding transformer are all wound around the iron core by a winding machine. For a conventional winding machine, the iron core needs to be segmented. After the three segments of the iron core are respectively wound to form the high-voltage coil winding, medium-voltage coil winding, and low-voltage coil winding, the iron core is then assembled. This processing method is cumbersome in operation and low in processing efficiency.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the Invention

Specific embodiments

[0036] The present invention provides a high and low voltage coil winding integrated machine for transformers. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following examples are given with reference to the accompanying drawings to further elaborate on the present invention in detail. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is the orientation or positional relationship based on the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0038] Such as Figures 1 to 12, A winding machine for high and low voltage coils of a transformer in this embodiment includes a first mounting base 10, a copper foil feeding mechanism 20, a welding mechanism 30, an insulating paper feeding mechanism 40, and a winding mechanism 50. This embodiment can be used for the production and processing of three-winding transformers. Before processing, first clamp and fix the iron core 86 with the clamping piece 56, and make the driven gear 87 sleeved on the iron core 86 mesh with the gear 59. Use the expandable fixture 22 to clamp the copper foil roll 81 and release the copper foil 82, and pull the copper foil 82 to the position of the welding mechanism 30. Weld the copper row 83 to the copper foil 82 with the welding assembly 39. Install the insulating paper roll 84 on the second coil mounting part 42 and release the insulating paper 85. Pull the copper foil 82 and the insulating paper 85 to the sleeve position of the iron core 86. Start the fifth driving device 57, and drive the gear 59 to rotate with the driving shaft 58. Since the driven gear 87 on the iron core 86 meshes with the gear 59, and the driven gear 87 is arranged on the sleeve, the copper foil 82 and the insulating paper 85 are driven to be wound and formed. After cutting, the first winding 80 is formed on the iron core 86. After winding, remove the sleeve and the driven gear 87, and install them on the second winding column of the iron core 86. Drive the mounting plate 55 to rotate through the fourth driving device 54, so that the clamping piece 56 drives the second winding column of the iron core 86 to be adjusted to the winding position. Then install the sleeve and the driven gear 87 on the second winding column of the iron core 86 to wind the second winding 80. According to this principle, until the winding of the three windings 80 is completed, the whole production process is tightly connected and the processing efficiency is high.

[0039] Please refer to Figure 1 , Figure 4 and Figure 6 , The copper foil feeding mechanism 20 includes a first bracket 21 arranged on the first mounting base 10 and movable along the y direction, an expandable fixture 22 rotatably arranged at one end of the first bracket 21 along the y direction, a first driving device 23 for driving the expandable fixture 22 to rotate, and a plurality of first coil mounting parts 24 rotatably arranged at the other end of the first bracket 21 along the y direction. The expandable fixture 22 is used to clamp the copper foil roll 81 and release the copper foil 82. The expandable fixture 22 can adopt an unspoked wheel self-centering expandable fixture disclosed in Chinese Patent Publication No. CN219747675U, which can facilitate the staff to install or remove the copper foil roll 81; moreover, in this application, the first bracket 21 is designed as a structure movable along the y direction, and the expandable fixture 22 and a plurality of first coil mounting parts 24 are respectively arranged at both ends of the first bracket 21 along the y direction, which can be selected according to the type or quantity of the coil. For example, when some windings 80 need to wind multiple coils such as copper foil 82, insulating paper 85, left and right spacers in sequence, the copper foil feeding mechanism 20 can be adjusted to the structure as shown in Figure 8 . Install the corresponding coils through a plurality of first coil mounting parts 24 respectively, so as to feed the materials more reasonably; through such a design in this embodiment, the production and processing of most types of windings 80 can be compatible, and the structure is ingenious.

After the copper foil 82 is drawn, it passes through the gap between the bottom bracket 35 and the pressing plate 38. When welding is required, the copper row 83 is placed above or below the copper foil 82. The second driving device 37 drives the pressing plate 38 to descend, and the pressing plate 38 is used to press the copper row 83 and the copper foil 82. Then, the welding assembly 39 is used to weld the copper row 83 to the copper foil 82. After welding is completed, the second driving device 37 drives the pressing plate 38 to rise, so that the copper foil 82 can be pulled and wound; as Figure 9 shown, the welding direction along the x direction can also be adjusted in this embodiment. When the welding direction needs to be switched, the sliding seat 32 is slid along the x direction to move it away, and then the welding assembly 39 is flipped. By sliding the sliding seat 32 along the x direction, a flipping space is provided for the welding assembly 39. Moreover, a first slider 34 slidable along the y direction on the first guide rail 33 is also provided in this embodiment. The first slider 34 is used to drive the welding assembly 39 to slide along the y direction. When welding is not required, the entire welding mechanism 30 can be moved away along the y direction to avoid affecting the winding operation.

[0041] As Figure 1 shown, the insulating paper feeding mechanism 40 includes a third driving device 41 fixed to the second bracket 31 and a second coil mounting member 42 connected to the output end of the third driving device 41.

The winding mechanism 50 is used to wind the copper foil 82 and the insulating paper roll 84 around the iron core 86. The plurality of clamps 56 clamp the iron core 86 together. The gear 59 can mesh with the driven teeth 87 on the iron core 86. The iron core 86 is detachably mounted with a sleeve. The driven teeth 87 have two driven teeth, and the two driven teeth 87 are respectively mounted on the sleeve along its axial direction. At both ends, before winding, the copper foil 82 and the insulating paper 85 are first pulled to the sleeve position of the iron core 86, and the fifth driving device 57 is started. The driving shaft 58 is used to drive the gear 59 to rotate. Since the driven tooth 87 on the iron core 86 is meshed with the gear 59, and the driven tooth 87 is set on the sleeve, the copper foil 82 and the insulating paper 85 are driven to be wound and formed. After cutting, the first winding 80 is formed on the iron core 86. After the winding is completed, the sleeve and the driven tooth 87 are removed and installed on the second winding column of the iron core 86. The fourth driving device 54 drives the mounting plate 55 to rotate, so that the clamp 56 drives the second winding column of the iron core 86 to adjust to the winding position, and then the sleeve and the driven tooth 87 are installed on the second winding column of the iron core 86 to rewind the second winding 80. According to this principle, the winding of the three windings 80 is completed. The winding of the three windings 80 is completed by rotating the switching position, and the structure is ingenious.
