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

[0019] The present invention provides a transformer high and low voltage coil winding integrated machine. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. 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.

[0020] In the description of the present invention, it should be understood that the descriptions involving orientations, such as up, down, front, back, left, right, etc., and the orientations or positional relationships indicated are based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

The present embodiment can be used for the production and processing of a three-winding transformer. Before processing, the iron core 86 is first clamped and fixed by a clamp 56, and the driven tooth 87 sleeved on the iron core 86 is meshed with the gear 59. The copper foil roll 81 is clamped by an open clamp 22 and the copper foil 82 is fed out. The copper foil 82 is pulled to the position of the welding mechanism 30. The copper bar 83 is welded to the copper foil 82 by a welding assembly 39. The insulating paper roll 84 is installed on the second coil mounting member 42 and the insulating paper 85 is fed out. The copper foil 82 and the insulating paper 85 are pulled to the sleeve position of the iron core 86. The fifth coil mounting member 42 is started. The driving device 57 utilizes the driving shaft 58 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 whole production process is compact and the processing efficiency is high.

The open clamp 22 is used to clamp the copper foil roll 81 and unload the copper foil 82. The open clamp 22 can be used as disclosed in Chinese Patent Publication No. CN219747675U. A self-centering open clamp for a spokeless wheel rim can facilitate the installation or removal of the copper foil roll 81 by the staff; moreover, the present application designs the first bracket 21 to be movable along the y direction, and the two ends of the first bracket 21 along the y direction are respectively provided with an open clamp 22 and a plurality of first coil mounting members 24, which can be selected according to the type of coil or the number of coils. For example, when some windings 80 need to be wound with copper foil 82, insulating paper 85, left and right spacers and other coils in sequence, the copper foil unwinding mechanism 20 can be adjusted to the following positions: Figure 8 The structure shown installs corresponding coils respectively through a plurality of first coil mounting members 24, so as to discharge the materials more reasonably.

The copper foil 82 passes through the gap between the bottom bracket 35 and the pressing plate 38 after being pulled. When welding is required, the copper bar 83 is placed above or below the copper foil 82, and the pressing plate 38 is driven down by the second driving device 37. The copper bar 83 and the copper foil 82 are pressed by the pressing plate 38, and then the copper bar 83 is welded to the copper foil 82 by the welding assembly 39. After welding is completed, the pressing plate 38 is driven up by the second driving device 37 so that the copper foil 82 can be pulled and wound; Fig. 9As shown, the present embodiment can also adjust the left and right welding directions along the x-direction. When the welding direction needs to be switched, the sliding seat 32 is slid away along the x-direction, and then the welding assembly 39 is flipped. The sliding seat 32 slides along the x-direction to provide a flipping space for the welding assembly 39. Moreover, the present embodiment further provides a first slider 34 that can slide on the first guide rail 33 along the y-direction. The first slider 34 is used to drive the welding assembly 39 to slide along the y-direction.

At the end, 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.
