Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment processing, in particular to a transformer coil varnish dipping device and process. Background Art

[0002] The transformer coil is an important process for insulating and moisture-proofing the transformer coil. The main purpose is to improve the insulation performance of the coil, enhance its mechanical strength and extend its service life. The transformer coil is usually cleaned and dried and then immersed in the paint liquid. The air and moisture inside the coil are reduced by vacuum treatment. However, the vacuum treatment cycle is long, which has certain restrictions on the varnishing material, which leads to certain limitations on the bubbles and immersion uniformity during the immersion process. The residual bubbles will prevent the varnishing material from fully penetrating into every part of the coil, forming insulation defects, which leads to a decrease in insulation performance and an increased risk of leakage and short circuit. Secondly, the transformer coil is usually placed directly in the lifting frame during the immersion process. The lack of a limit device means that the coil has no fixed position during lifting and may collide with other components, increasing the risk of coil damage, which in turn affects the product quality. In response to the above problems, the inventor proposes a transformer coil varnishing device and process for solving the above problems. Summary of the invention

[0033] By adopting the above technical solution, uniform varnish dipping of the transformer coil is achieved.

[0034] 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. Figure 3 As shown, the driving end of the electric cylinder 811 extends and pushes the gear ring 806 to rotate counterclockwise under the guidance of the fixing bolt 805, and the gear 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 half gear 802 and the rotating disk 803 rotate through the arc groove 808 and the guide groove 807 to drive the corresponding limit rod 809 to expand centripetally and fit the inner side of the transformer coil to limit and fix the transformer coil, and then control to start the No. 1 motor 406, as shown in FIG. Fig.10 As shown, the first motor 406 drives the threaded screw 404 to rotate, and the threaded screw 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 liquid in the paint immersion pool 1.
