An impregnation device for dry-type transformer coils

Abstract

This utility model relates to the field of dry-type transformer coil processing technology, and in particular to an impregnation device for dry-type transformer coils. It includes an impregnation tank, a support frame fixed to the top of the impregnation tank, several sets of support frames symmetrically fixed to the top of the impregnation tank, hydraulic telescopic rods fixed to the top of the support frames (the number of hydraulic telescopic rods is the same as the number of support frames), and a support hook fixed to the top of the output shaft of the hydraulic telescopic rods. The hydraulic telescopic rods can drive the support hook fixed to the top of the output shaft to move.

Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer coil processing technology, specifically to an impregnation device for dry-type transformer coils. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery, and other applications. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). With natural air cooling, the transformer can operate continuously at its rated capacity for extended periods. With forced air cooling, the transformer's output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; however, because load losses and impedance voltage increases significantly under overload conditions, resulting in uneconomical operation, it should not be subjected to prolonged continuous overload operation.

[0003] Currently, some dry-type transformers require impregnation treatment during production to cover the coils with one or more layers of insulating varnish, improving their insulation performance. However, during the impregnation treatment and transfer to drying equipment, some dry-type coils may have undried insulating varnish dripping from the bottom of the coils, causing ground pollution and requiring personnel to clean the ground, increasing their workload and making the use relatively inconvenient. To address this, we propose an impregnation device for dry-type transformer coils to solve or improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an impregnation device for dry-type transformer coils to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An impregnation device for dry-type transformer coils includes an impregnation tank, a support frame fixed to the top of the impregnation tank, a hydraulic telescopic rod fixed to the top of the support frame, a support hook fixed to the top of the output shaft of the hydraulic telescopic rod, and a groove formed inside the support frame.

[0006] The support hook has a support beam inside, and the number of support beams is the same as the number of support hooks. The surface of the support beam has a transport port, and two sets of transport ports are symmetrically arranged on the surface of a set of support beams. A turntable is rotatably mounted on the surface of the support beam via a rotating shaft, and two sets of turntables are symmetrically installed on the surface of a set of support beams.

[0007] As a preferred embodiment of this utility model, gears are fixed on the surface of the turntable, and the number of gears is the same as the number of turntables; racks are fixed on the surface of the support frame, and the number of racks is the same as the number of gears.

[0008] In a preferred embodiment of this utility model, the rack is located on one side of the gear and meshes with the gear, and a connecting rod is fixed on the surface of the turntable, the number of the connecting rods being the same as the number of turntables.

[0009] As a preferred embodiment of this utility model, a receiving chamber is fixed to the top of the connecting rod. The receiving chamber is fixed between the two sets of connecting rods and is simultaneously fixedly connected to the two sets of connecting rods. A receiving box is inserted inside the receiving chamber, and a hidden handle is provided on the surface of the receiving box.

[0010] As a preferred embodiment of this utility model, the surface of the gear is rotatably mounted with a limiting block via a rotating shaft. The number of limiting blocks is the same as the number of gears. The limiting block is located inside the slide groove and is slidably connected to the support frame via the slide groove.

[0011] As a preferred embodiment of this utility model, the bottom of the supporting beam is fixed with a hook, the number of hooks being the same as the number of supporting beams, and a transformer coil is provided inside the hook, the number of transformer coils being the same as the number of hooks.

[0012] As a preferred embodiment of this utility model, several sets of support frames are symmetrically fixed on the top of the immersion tank, and two sets of sliding grooves are symmetrically opened inside one set of support frames.

[0013] In a preferred embodiment of this utility model, the number of hydraulic telescopic rods is the same as the number of support frames, and the number of support hooks is the same as the number of hydraulic telescopic rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up a receiving chamber and a receiving box, the receiving chamber can be moved during the transfer of the transformer coil, and the receiving box can be moved to the bottom side of the transformer coil. In this way, the receiving box can catch the undried insulating varnish dripping from the bottom of the transformer coil, thereby avoiding the insulating varnish from dripping directly onto the ground and causing pollution. There is no need for personnel to clean the ground, which reduces the workload of personnel and makes it relatively convenient to use.

[0015] 2. In this utility model, by setting a rack and gear, when the support beam moves and drives the hook and transformer coil to move closer to the impregnation tank, the gear will drive itself to rotate through the rack, thereby driving the turntable and connecting rod to rotate, which in turn drives the receiving bin and receiving box to rotate, thus rotating the receiving bin and receiving box to the top side of the transformer coil. This prevents the receiving bin and receiving box from entering the impregnation tank and affecting the impregnation treatment of the transformer coil, thus improving the effectiveness of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] For examples, please refer to Figures 1-3 This utility model provides a technical solution: An impregnation device for dry-type transformer coils includes an impregnation tank 1, a support frame 2 fixed to the top of the impregnation tank 1, several sets of support frames 2 symmetrically fixed to the top of the impregnation tank 1, hydraulic telescopic rods 3 fixed to the top of the support frame 2, the number of hydraulic telescopic rods 3 being the same as the number of support frames 2, support hooks 8 fixed to the top end of the output shaft of the hydraulic telescopic rods 3, the hydraulic telescopic rods 3 driving the support hooks 8 fixed to the top end of the output shaft to move, the number of support hooks 8 being the same as the number of hydraulic telescopic rods 3, a sliding groove 6 opened inside the support frame 2, two sets of sliding grooves 6 symmetrically opened inside one set of support frames 2, and a support beam 9 placed inside the support hook 8, the number of support beams 9 being the same as the number of support hooks 8, the movement of the support hook 8 driving the support hooks 8 to move. The supporting beam 9 of the part moves. A transport slot 14 is provided on the surface of the supporting beam 9. Two sets of transport slots 14 are symmetrically provided on the surface of a set of supporting beams 9. When the supporting beam 9 moves, it drives the transport slots 14 on its surface to move. A turntable 13 is rotatably mounted on the surface of the supporting beam 9 via a rotating shaft. Two sets of turntables 13 are symmetrically mounted on the surface of a set of supporting beams 9. When the supporting beam 9 moves, it drives the rotatably connected turntables 13 to move. Gears 12 are fixed on the surface of the turntable 13. The number of gears 12 is the same as the number of turntables 13. When the turntable 13 moves, it drives the fixed gears 12 to move. A rack 7 is fixed on the surface of the support frame 2. The number of racks 7 is the same as the number of gears 12. The racks 7 are located on one side of the gears 12 and the racks 7... The gear 12 meshes with the rack 7. When the gear 12 moves, it rotates through the meshing rack 7. When the gear 12 rotates, it drives the fixedly connected turntable 13 to rotate. The surface of the turntable 13 is fixed with connecting rods 11. The number of connecting rods 11 is the same as the number of turntables 13. When the turntable 13 rotates and moves, it drives the fixedly connected connecting rods 11 to rotate and move. The top of the connecting rod 11 is fixed with a receiving chamber 4. The receiving chamber 4 is fixed between the two sets of connecting rods 11 and is fixedly connected to both sets of connecting rods 11. When the connecting rod 11 rotates, it drives the fixed receiving chamber 4 to rotate. A receiving box 10 is inserted inside the receiving chamber 4. When the receiving chamber 4 rotates, it drives the internally inserted receiving box 10 to rotate. The surface of the receiving box 10 is provided with a hidden handle. 17. The receiving box 10 can be moved by pulling the concealed handle 17, thereby pulling the receiving box 10 out from the inside of the receiving compartment 4, which facilitates the uniform treatment of the insulating varnish inside the receiving box 10. The surface of the gear 12 is rotatably mounted with limit blocks 16 via a rotating shaft. The number of limit blocks 16 is the same as the number of gears 12. The limit blocks 16 are located inside the slide groove 6 and are slidably connected to the support frame 2 through the slide groove 6. When the gear 12 moves, it will drive the rotatably connected limit blocks 16 to move. The limit blocks 16 can restrict the position of the support beam 9 through the rotatably connected turntable 13, reducing or avoiding the tilting and shaking of the support beam 9 when it moves, thus improving the stability of the support beam 9 when it moves. The bottom of the support beam 9 is fixed with a hook 15.The number of hooks 15 is the same as the number of supporting beams 9. When the supporting beams 9 move, they will drive the fixed hooks 15. A transformer coil 5 is installed inside each hook 15. The number of transformer coils 5 is the same as the number of hooks 15. When the hooks 15 move, they will drive the transformer coils 5 inside to move.

[0020] The working process of this utility model is as follows: When the transformer coil 5 needs to be transferred, the hydraulic telescopic rod 3 will drive the support hook 8 to move, which in turn drives the support beam 9 to move. This allows the support beam 9 to move the transformer coil 5 via the hook 15, thus removing the transformer coil 5 from the impregnation tank 1. Simultaneously, the movement of the support beam 9 will drive the turntable 13 and gear 12 to move, causing the gear 12 to rotate via the rack 7. This rotation of the gear 12 will then drive the turntable 13 to rotate. The rotation of the turntable 13 will then drive the receiving chamber 4 to rotate via the connecting rod 11, causing the receiving chamber 4 to rotate and the receiving box 10 to rotate. The receiving chamber 4 and receiving box 10 will rotate at a certain angle and move to the bottom of the transformer coil 5. When the support beam 9 reaches a certain height, the gear 12 will disengage from the rack 7. At this point, the receiving chamber 4 and receiving box 10 will rotate to the bottom of the transformer coil 5 by gravity, thus allowing the receiving box 10 to collect the undried insulation dripping from the bottom of the transformer coil 5. The varnish is collected in a container to prevent the insulating varnish from dripping directly onto the ground and causing pollution. This eliminates the need for personnel to clean the ground, reducing workload and making the device relatively convenient to use. When the limit block 16 moves to the top of the slide 6, the support beam 9 can be removed from the support frame 2 by inserting the fork arm of the transfer forklift into the transport slot 14, thus realizing the transfer of the transformer coil 5. At the same time, when the limit block 16 is placed inside the support frame 2 and the support beam 9 is placed inside the support hook 8, the hydraulic telescopic rod 3 drives the support hook 8 and the support beam 9 to move. The gear 12 will rotate itself through the rack 7, thereby driving the turntable 13 and the connecting rod 11 to rotate. This, in turn, drives the connecting rod 11 to rotate the receiving chamber 4 and the receiving box 10, causing the receiving chamber 4 and the receiving box 10 to rotate to the top side of the transformer coil 5. This prevents the receiving chamber 4 and the receiving box 10 from entering the impregnation tank 1 and affecting the impregnation treatment of the transformer coil 5, thus improving the effectiveness of the device.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
