Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer coil impregnation device. Background Technology

[0002] In transformer manufacturing, coil impregnation is a crucial process. Its purpose is to form a uniform and dense insulating varnish film on the surface of the transformer coil, enhancing its insulation performance, mechanical strength, and resistance to moisture and corrosion. Traditional transformer coil impregnation devices suffer from the following problems: uneven impregnation, with some areas impregnated too thickly while others are impregnated too thinly or not at all, leading to inconsistent coil insulation performance, affecting the overall performance and reliability of the transformer; and significant varnish waste, as a large amount of varnish is wasted during the impregnation process due to the inability to effectively recycle it, increasing production costs. Utility Model Content

[0003] This invention proposes a transformer coil impregnation device to solve the problem of excessively thick impregnation in existing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transformer coil impregnation device, comprising an impregnation component, the impregnation component comprising a container part and a support part, the top of the container part being open to form a paint storage cavity for storing paint, the support part comprising an electric telescopic rod, the electric telescopic rod being fixedly connected to the bottom of the container part, and the telescopic end of the electric telescopic rod being fixedly connected to a moving rod, the inside of the moving rod being fixedly connected to a motor, the output end of the motor being fixedly connected to a centrifugal basket, the centrifugal basket being located inside the paint storage cavity.

[0005] Preferably, a partition frame is fixedly connected inside the centrifuge basket, and a placement cavity for placing the coil is formed between the partition frame and the inner wall of the centrifuge basket.

[0006] Preferably, the container portion includes a paint storage tank, the paint storage cavity is formed inside the paint storage tank, and a shielding member for shielding the paint storage cavity is rotatably connected to the top of the paint storage tank. A foot for supporting itself is fixedly connected to the bottom of the paint storage tank, and the electric telescopic rod is fixedly connected to the bottom of the paint storage tank.

[0007] Preferably, the shielding component includes a cover plate, the top of which is fixedly connected to a handle, and a handle lock is rotatably connected to the cover plate.

[0008] Preferably, the bottom of the cover plate is rotatably connected to a rotating shaft, and the free end of the rotating shaft is fixedly connected to a baffle.

[0009] Preferably, a guide for adding coils is fixedly connected to one side of the paint storage tank. The guide includes a guide frame, and a feeding hole is formed on one side of the paint storage tank. The guide frame is fixedly connected to the paint storage tank, and a guide cavity for guiding the movement of the coil is formed on the guide frame. The guide cavity is connected to the feeding hole.

[0010] Preferably, the inner wall of the material guiding cavity is rotatably connected to a one-way plate that rotates unidirectionally toward the feeding hole, and a slope is formed inside the material guiding cavity, wherein the horizontal height of the slope on the side closer to the one-way plate is lower than the horizontal height on the other side.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: (1) An electric telescopic rod, a moving rod, a motor and a centrifugal basket are set up. After the coil is impregnated with varnish, the electric telescopic rod drives the moving rod and the centrifugal basket to move above the anti-rust varnish. The motor drives the centrifugal basket to rotate, so that the excess varnish on the surface of the coil falls off under the action of centrifugal force, making the impregnation more uniform and avoiding excessive varnish in some areas. This ensures that the insulation performance of the coil is consistent and will not affect the overall performance and reliability of the transformer. It also avoids serious waste of varnish. During the impregnation process, it is easy to recover the varnish and reduce production costs. (2) Set up a separator rack. When in use, the coil is placed in the placement cavity formed by the separator rack and the centrifugal basket to avoid the coil colliding with each other when rotating, reduce the probability of coil damage, and improve the uniformity of coil impregnation. (3) Set up a guide rack, a feeding hole and a guide cavity. When in use, add the coil through the guide rack, and let the coil slide through the guide cavity into the feeding hole, and then let the coil fall into the centrifuge basket. There is no need to open the device to add the coil, which reduces the difficulty of adding the coil, improves the coil adding efficiency, and thus improves the coil impregnation efficiency. (4) A one-way plate is set up. When the coil is added to the centrifuge basket through the guide rack, the one-way plate can only rotate in one direction, thus avoiding the paint from accidentally splashing to the outside of the device and polluting the environment. No cleaning is required later, which improves the convenience of using the device. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-8 As shown, the present invention provides a transformer coil impregnation device, including an impregnation component 3. The impregnation component 3 includes a container part and a support part. The top of the container part is open to form a paint storage cavity for storing paint. The support part includes an electric telescopic rod 36, which is fixedly connected to the bottom of the container part. The telescopic end of the electric telescopic rod 36 is fixedly connected to a moving rod 37. A motor 38 is fixedly connected inside the moving rod 37. A centrifugal basket 35 is fixedly connected to the output end of the motor 38. The centrifugal basket 35 is located inside the paint storage cavity.

[0016] With the above technical solution, before immersing the coil in the anti-rust paint, the anti-rust paint is poured into the paint storage chamber inside the container. After the anti-rust paint is poured in, the coil to be treated is poured into the centrifugal basket 35. The electric telescopic rod 36 is operated to move the centrifugal basket 35, causing the centrifugal basket 35 to move the coil downwards until the coil is completely immersed in the anti-rust paint. After the coil is fully immersed in the anti-rust paint, the electric telescopic rod 36 is operated to move the centrifugal basket 35, causing the centrifugal basket 35 to move the coil downwards until the coil is completely moved to the outside of the anti-rust paint. The motor 38 is operated to rotate the centrifugal basket 35, causing the excess paint adhering to the coil in the centrifugal basket 35 to fall off under the action of centrifugal force. After the coil is treated, it can be moved to other workstations for drying.

[0017] To separate multiple coils, such as Figures 6-7 As shown, a separator 34 is fixedly connected inside the centrifuge basket 35, and a placement cavity for placing coils is formed between the separator 34 and the inner wall of the centrifuge basket 35.

[0018] In this embodiment, before placing the coil in the centrifuge basket 35, the separator 34 is placed inside the centrifuge basket 35. After the separator 34 is placed, the coil is placed through the placement cavity formed between the separator 34 and the centrifuge basket 35 to avoid collision of the coil during centrifugation.

[0019] Specifically, in one embodiment, regarding the aforementioned container portion, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the container part includes a paint storage tank 32, a paint storage cavity is formed inside the paint storage tank 32, and a shielding member 2 for shielding the paint storage cavity is rotatably connected to the top of the paint storage tank 32. A foot 31 for supporting itself is fixedly connected to the bottom of the paint storage tank 32, and an electric telescopic rod 36 is fixedly connected to the bottom of the paint storage tank 32.

[0020] In this embodiment, before processing the coil, the paint storage tank 32 is supported by the base 31. After the paint storage tank 32 is placed stably, the shield 2 is rotated to fully open the shield 2, and the anti-rust paint is poured into the paint storage tank 32. After the anti-rust paint is added, the coil can be placed in the centrifuge basket 35, the shield 2 is closed, and the centrifuge basket 35 is moved under the anti-rust paint by the electric telescopic rod 36, so that the coil is immersed in the anti-rust paint and then centrifuged.

[0021] Furthermore, in this utility model, regarding the aforementioned shielding member 2, as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the shielding component 2 includes a cover plate 21, a handle 22 is fixedly connected to the top of the cover plate 21, and a handle lock 23 is rotatably connected to the cover plate 21.

[0022] In this embodiment, before opening the cover plate 21, pull the handle lock 23 to open the handle lock 23. Then, pull the cover plate 21 around the paint storage tank 32 by the handle 22 to open the paint storage tank 32, so that anti-rust paint can be added for subsequent processing of the coil.

[0023] To prevent the coil from accidentally moving outside the centrifuge basket 35 during centrifugation, such as Figures 5-7 As shown, a rotating shaft 25 is rotatably connected to the bottom of the cover plate 21, and a baffle 24 is fixedly connected to the free end of the rotating shaft 25.

[0024] In this embodiment, after the coil is fully soaked in anti-rust paint, the electric telescopic rod 36 is operated to move the centrifuge basket 35 upward until the baffle 24 blocks the centrifuge basket 35. When the centrifuge basket 35 rotates to centrifuge the coil, the coil is prevented from being accidentally thrown outside the centrifuge basket 35.

[0025] To facilitate the addition of the coil to the interior of the centrifuge basket 35, such as Figures 1-3 , Figures 6-7 As shown, a guide component 1 for adding coils is fixedly connected to one side of the paint storage tank 32. The guide component 1 includes a guide frame 11. One side of the paint storage tank 32 is open to form a feeding hole 33. The guide frame 11 is fixedly connected to the paint storage tank 32, and a guide cavity 12 for guiding the movement of the coil is formed on the guide frame 11. The guide cavity 12 is connected to the feeding hole 33.

[0026] In this embodiment, after the anti-rust paint is added to the inside of the paint storage tank 32, the cover plate 21 is closed, the coil is added to the inside of the guide rack 11, and the coil is guided by the guide cavity 12 inside the guide rack 11, so that the coil slides through the feeding hole 33 into the inside of the centrifuge basket 35, and the coil is immersed in the anti-rust paint.

[0027] When personnel add coils via the guide rack 11, to prevent paint from accidentally splashing onto the outside of the paint storage tank 32, such as... Figures 1-3 As shown, a one-way plate 13 that rotates unidirectionally toward the feeding hole 33 is rotatably connected to the inner wall of the material guiding cavity 12. A slope is formed inside the material guiding cavity 12, and the horizontal height of the side of the slope near the one-way plate 13 is lower than the horizontal height of the other side.

[0028] In this embodiment, when a person adds a coil, the coil slides through the guide cavity 12 toward the feeding hole 33, thereby pushing the one-way plate 13 to rotate, causing the coil to slide into the centrifuge basket 35. After the coil falls into the centrifuge basket 35, the one-way plate 13 automatically rotates back to its original position, thereby blocking the feeding hole 33 and preventing paint from accidentally splashing to the outside of the device.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
