Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment processing, and particularly to a transformer coil impregnating device and process. Background Art

[0002] Transformer coil impregnation is an important process for insulating and moisture-proofing transformer coils. The main purposes are to improve the insulation performance of the coils, enhance their mechanical strength, and extend their service life. Usually, the transformer coils need to be cleaned and dried and then immersed in the paint solution. Vacuum treatment is used to reduce the air and moisture inside the coils. However, the vacuum treatment cycle is relatively long, and there are certain limitations on the impregnating materials. As a result, there are certain limitations in the bubbles and impregnating uniformity during the impregnating process. The residual bubbles will prevent the impregnating material from fully penetrating into each part of the coil, forming insulation defects, which will lead to a decline in insulation performance and an increase in the risk of leakage and short circuit. Secondly, during the impregnating process of the transformer coil, it is usually directly placed in the lifting frame. Without a limiting device, the coil may collide with other components during lifting, increasing the risk of coil damage and thus affecting the product quality. To solve the above problems, the inventor proposes a transformer coil impregnating device and process. Summary of the Invention

[0010] A process used in a transformer coil varnish dipping device comprises the following steps:

[0011] S1. First, clean the surface of the transformer coil to ensure that there is no dust, oil or other impurities on the coil surface;

[0012] S2. Place the processed transformer coil on the coil limit adjustment component, and limit the coil through the coil limit adjustment component to ensure the stability of the coil during the paint dipping process;

[0013] S3, control the screw-type lifting assembly to drive the transformer coil to descend until it is completely immersed in the paint liquid;

[0014] S4. Control the intermittent rotation component to drive the transformer coil in the paint liquid. At the same time, the vibration generating component drives the transformer coil to vibrate in the paint liquid as the adjustment frame rotates. The rotation of the coil in the paint liquid will generate flow, which helps bubbles move from the coating to the liquid surface and escape. The vibration can further break the bubbles and accelerate their dissipation, thereby reducing the number of bubbles.

[0015] S5. After the transformer coil is dipped in paint, it is placed in an oven or curing equipment and cured according to the temperature and time required by the material to ensure that the dipped paint material is completely dry and cured.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting an intermittent rotation component and a vibration generation component, the intermittent rotation component drives the adjustment frame to perform periodic intermittent rotation, and at the same time, the vibration generation component drives the adjustment frame to vibrate synchronously. The adjustment frame drives the transformer coil to rotate in the paint liquid, which will generate flow, helping bubbles move from the coating to the liquid surface and escape. Combining with vibration can further break the bubbles and accelerate their dissipation, thus effectively reducing the number of bubbles and improving the uniformity of the transformer coil impregnation liquid.

[0018] 2. By setting a coil limit adjustment component, the rotation of the toothed ring drives several semi-gears to rotate synchronously. While the semi-gears rotate, they drive the corresponding rotating disks to rotate in the opposite direction. When the semi-gears and the rotating disks rotate, the corresponding limiting rods move synchronously and centripetally expand through the mutual cooperation of the arc-shaped grooves and the guide grooves to contact the inner side of the transformer coil, thereby achieving the effect of limiting the transformer coil, ensuring the stability of the transformer coil during the impregnation process, reducing damage and improving product quality.

[0019] 3. By setting an intermittent rotation component, the intermittent rotation component stirs the paint liquid while driving the transformer coil to rotate, which can enhance the fluidity in the paint liquid, improve the dispersibility of the paint liquid, and avoid the influence on the impregnation effect caused by the precipitation of paint liquid substances to form a stratification phenomenon.

[0053] A process used in a transformer coil impregnating device includes the following steps:

[0055] S2. Place the processed transformer coil on the coil limit adjustment component 8, and limit the coil through the coil limit adjustment component 8 to ensure the stability of the coil during the impregnating process;

[0056] S3. Control the screw-type lifting component 4 to drive the transformer coil to descend until it is completely immersed in the paint solution;

[0057] S4. Control the intermittent rotation component 6 to drive the transformer coil to rotate in the paint solution while driving the transformer coil to vibrate in the paint solution through the vibration generating component 7. The rotation of the coil in the paint solution will generate flow, helping the bubbles to move from the coating to the liquid surface and escape. Vibration can further break the bubbles and accelerate their dissipation, thereby reducing the number of bubbles;

[0058] S5. After the transformer coil is completely immersed in paint, place it in an oven or curing equipment and cure it according to the temperature and time required by the material to ensure that the impregnating material is completely dried and cured.

[0059] By adopting the above technical solution, uniform impregnation of the transformer coil is achieved.

[0060] Working principle: First, place the cleaned transformer coils on the corresponding lower limit rods 809 in sequence, and then control the electric cylinder 811 to start. As Figure 3 shown, the driving end of the electric cylinder 811 extends and pushes the toothed ring 806 to rotate counterclockwise under the guidance of the fixed bolt 805. The toothed ring 806 drives the half gear 802 to rotate counterclockwise synchronously. The half gear 802 drives the corresponding rotating disk 803 to rotate clockwise through the transmission rod 804. The rotation of the half gear 802 and the rotating disk 803 drives the corresponding limit rod 809 to expand centripetally and fit with the inner side of the transformer coil to limit and fix the transformer coil. Then control the first motor 406 to start. As Figure 10 shown, the first motor 406 drives the threaded screw rod 404 to rotate. The threaded screw rod 404 drives the lifting frame 601 to descend under the guidance of the slide rail 401 through the lifting block 405 and the lifting frame 402, so that the transformer coil is completely immersed in the paint solution in the impregnation tank 1. During the descent of the lifting frame 601, the right rotating wheel 611 is driven to slide synchronously on the drive shaft 610 through the extension frame 609. Then close the top cover 3 and control the second motor 612 to start. The second motor 612 drives the drive shaft 610 to rotate. The drive shaft 610 drives the rotating cylinder 603 to rotate synchronously through the two rotating wheels 611 and the synchronous belt. As Figure 5 shown, the rotating cylinder 603 drives the transmission shaft 604 to rotate through the driving gear 607 and the driven gear 608. The transmission shaft 604 drives the intermittent rotation frame 605 to rotate intermittently through the rotating rod 606. The rotating rod 606 rotates one circle to drive the intermittent rotation frame 605 to rotate a quarter of a circumference. The intermittent rotation frame 605 drives the adjustment frame 801 to rotate intermittently synchronously through the vibration plate 613, the guide post 710 and the side plate 711. The rotation of the adjustment frame 801 drives the transformer coil to rotate synchronously in the paint solution. As Figure 8As shown, the rotation of the transmission shaft 604 drives the driven shaft 702 to rotate synchronously. The driven shaft 702 drives the drive rod 706 to swing with the connection point with the limit plate 705 as the axis through the eccentric shaft 703 and the rotating block 704. The drive rod 706 drives the lifting rod 708 to reciprocate up and down under the guidance of the rotating cylinder 603 through the connecting rod 707. The lifting rod 708 drives the adjusting frame 801 to vibrate through the mutual cooperation of the trapezoidal column 709, the guiding column 710 and the spring 712. The vibration of the adjusting frame 801 drives the corresponding transformer coil to vibrate in the paint liquid, and further breaks the bubbles through vibration to accelerate the dissipation of the bubbles.
