Description

Technical Field

[0001] The utility model relates to the technical field of transformer coil potting, in particular to a stable potting device for transformer coils. Background Technique

[0002] A transformer coil is a kind of coil, and a transformer needs a coil to operate. Coils are usually divided into two types: layer type and pancake type. A layer type coil means that the turns of the coil are arranged continuously in layers along the axial direction. A pancake type coil means that the turns of the coil are continuously wound into a wire pancake (segment) along the radial direction, and then many wire pancakes are arranged along the axial direction to form a coil; there are also pancake type coils and foil type coils between the layer type and the pancake type. The common cause of transformer short circuit is that the insulation part in its power supply system is damaged. To improve the anti - sudden - short - circuit ability of the transformer, it is necessary to enhance the overall strength of the transformer coil. Usually, an insulating glue with excellent insulation performance is used for the potting process of the transformer coil.

[0003] When the existing stable potting device for transformer coils performs potting operations, due to the relatively tight structure of the transformer coil, it is easy to have insufficient impregnation of the coil gap with glue, resulting in poor insulation effect. Moreover, if the glue is not drained in time after the potting of the transformer coil, bead - like protrusions will be generated on the surface of the coil after the insulating glue solidifies. When the bead - like protrusions block the air duct, it will affect the heat dissipation of the transformer, thus reducing the service performance of the transformer and being not conducive to people's use. Therefore, the technical personnel in this field provide a stable potting device for transformer coils to solve the problems raised in the above - mentioned background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the embodiments of the present utility model, a stable glue filling device for a transformer coil includes a workbench 1 and a glue filling table 2. The glue filling table 2 is arranged above the workbench 1, and a plurality of evenly distributed placement cylinders 3 are fixedly installed on the top of the glue filling table 2 for placing the transformer coil.

[0022] A vibration mechanism for full penetration during the potting of the transformer coil is provided between the top of the workbench 1 and the bottom of the potting table 2. The vibration mechanism includes a vibration motor 41, a first shock-absorbing spring 42, a moving block 43, a movable rod 44, and a second shock-absorbing spring 45. A vibration motor 41 is installed at one side of the bottom of the potting table 2 by bolts. Installation blocks 9 distributed in a rectangle are welded on the top of the workbench 1. The first shock-absorbing springs 42 are welded on the top surfaces of the installation blocks 9. The other ends of the first shock-absorbing springs 42 are welded to the bottom of the potting table 2. Moving grooves 10 located on the top of the workbench 1 are opened on the sides of the installation blocks 9 close to each other horizontally. The moving blocks 43 are slidably connected to the interiors of the moving grooves 10. The tops of the moving blocks 43 extend out of the interiors of the moving grooves 10 and are hinged to the movable rods 44. The other ends of the movable rods 44 are hinged to the bottom of the potting table 2 through fixing blocks 11. Both ends of the second shock-absorbing spring 45 are welded between the side surfaces of the moving blocks 43 and the installation blocks 9 close to each other.

[0023] First telescopic rods 46 penetrating through the first shock-absorbing springs 42 are fixedly installed between the bottom of the potting table 2 and the top surfaces of the installation blocks 9. Second telescopic rods 47 penetrating through the second shock-absorbing springs 45 are fixedly installed on one side of each installation block 9. The top surfaces of the movable ends of the second telescopic rods 47 are fixedly installed on the side walls of the moving blocks 43. The provided first telescopic rods 46 and second telescopic rods 47 are used to prevent the first shock-absorbing spring 42 and the second shock-absorbing spring 45 from undergoing lateral deformation respectively.

[0024] During use, start the vibration motor 41. When the output end of the vibration motor 41 vibrates, it drives the potting table 2 to vibrate accordingly. When the potting table 2 vibrates, the first shock-absorbing spring 42 and the first telescopic rod 46 are compressed and rebound accordingly. The resilience and buffering property of the first shock-absorbing spring 42 are used to facilitate the vibration of the potting table 2 in cooperation with the vibration motor 41. At the same time, the first shock-absorbing spring 42 can play a buffering role during the vibration operation of the potting table 2, so that the transformer coil can be stably placed in the placing cylinder 3. While the potting table 2 vibrates up and down, one end of the movable rod 44 hinged to its bottom rotates through the fixing block 11. At this time, the other end of the movable rod 44 drives the moving block 43 to move closer to or away from each other inside the moving groove 10. When the moving block 43 moves, the second shock-absorbing spring 45 and the second telescopic rod 47 are compressed or rebound, so as to further play a buffering role during the vibration operation of the potting table 2, ensuring the stability of the glue penetration of the transformer coil. At the same time, by controlling the vibration of the potting table 2 through the set vibration motor 41, it can promote the penetration of the glue into the gaps of the transformer coil, thereby improving the uniformity of the potting of the transformer coil, and further improving its insulation performance.

[0025] On the side of the glue filling table 2, there is a driving mechanism located on the top of the workbench 1. The driving mechanism includes a driving motor 51, a threaded rod 52, a round rod 53, a support frame 54 and a support plate 55. On one side of the workbench 1, the driving motor 51 is installed by bolts. On the side of the glue filling table 2, rectangular grooves 12 located on the top of the workbench 1 are symmetrically opened. The output end of the driving motor 51 is fixedly connected to the threaded rod 52 through a rotating shaft. The other end of the threaded rod 52 passes through the workbench 1 and is rotatably connected to the inner wall of the rectangular groove 12 through a bearing seat. Both ends of the round rod 53 are welded inside the other rectangular groove 12. Inside the rectangular grooves 12, support frames 54 that penetrate the threaded rod 52 and the round rod 53 are symmetrically and slidably connected respectively. The tops of the support frames 54 all extend to the top of the workbench 1 and are welded to the bottom surface of the support plate 55. The support frames 54 are respectively rotationally connected to the threaded rod 52 through threads and are slidably connected to the round rod 53.

[0026] During use, start the driving motor 51. When the output end of the driving motor 51 rotates, it drives the threaded rod 52 to rotate accordingly. Through the rotation of the threaded rod 52, the support frames 54 connected to it slide towards the glue filling table 2 in the rectangular grooves 12. When the support frames 54 move, they drive another group of support frames 54 to slide in the round rod 53 and the corresponding rectangular grooves 12 through the support plate 55. The round rod 53 is used to provide position limitation and stable moving support for the support frames 54 connected to it.

[0027] Connected to the bottom surface of the support plate 55 is a glue filling mechanism located above the glue filling table 2 for filling the transformer coil with glue. The glue filling mechanism includes a glue storage tank 61, a hydraulic rod 62, a connecting plate 63, a glue filling cylinder 64 and a glue filling pipe 65. The top surface of the support plate 55 is fixedly installed with the glue storage tank 61. On the bottom surface of the support plate 55, hydraulic rods 62 located above the glue filling table 2 are symmetrically installed by bolts. The top surfaces of the movable ends of the hydraulic rods 62 are all installed on the top of the connecting plate 63 by bolts. The bottom of the connecting plate 63 is fixedly installed with a number of glue filling cylinders 64 distributed side by side. One end of each glue filling cylinder 64 away from the connecting plate 63 is rotationally connected to a glue filling head 66 through threads. And between the top end of one side of the glue filling cylinder 64 and the inside of the glue storage tank 61, they are connected through the glue filling pipe 65. A control valve is arranged on the surface of the glue filling pipe 65 close to the glue storage tank 61, which is used to control the glue in the glue storage tank 61 to flow into the glue filling cylinder 64 through the glue filling pipe 65.

[0028] During use, when the support plate 55 drives the hydraulic rod 62 to move to the top of the placing cylinder 3, start the hydraulic rod 62 to make its movable end extend, thereby driving the glue filling cylinder 64 to move downward towards the top of the placing cylinder 3 through the connecting plate 63. When the glue filling head 66 reaches the top of the placing cylinder 3, open the control valve to make the glue in the glue storage tank 61 flow into the glue filling cylinder 64 through the glue filling pipe 65, and then fill the transformer coil in the placing cylinder 3 through the glue filling head 66.

[0029] Inside the placing cylinder 3, there is a glue draining mechanism extending to the top of the glue filling table 2 for draining the glue from the transformer coil after glue filling. The glue draining mechanism includes a glue draining cylinder 71, a connecting rod 72, an electric push rod 73, a lifting plate 74 and a glue discharging assembly. The glue draining cylinder 71 is movably placed inside the placing cylinder 3. At both ends of the top of the glue draining cylinder 71, fixing rods 75 are symmetrically welded. The ends of the fixing rods 75 away from the glue draining cylinder 71 are welded to the bottom of the connecting rod 72. On the top of the glue filling table 2, electric push rods 73 distributed in a rectangle are installed by bolts. The tops of the movable ends of the electric push rods 73 are respectively fixed to both ends of the bottom of the lifting plate 74, and the side ends of the connecting rod 72 are welded to the side surfaces of the lifting plate 74. At the bottom of the glue draining cylinder 71, there is a glue discharging assembly communicating with the inside of the placing cylinder 3 and extending to the bottom of the glue filling table 2. The glue discharging assembly includes a shunt pipe 81 and a glue discharging pipe 82. At the bottom of the glue draining cylinder 71, shunt pipes 81 communicating with the inside of the placing cylinder 3 are provided. The other ends of the shunt pipes 81 all extend to the bottom of the glue filling table 2 and are connected to the ends of the glue discharging pipe 82. The end of the glue discharging pipe 82 away from the shunt pipe 81 penetrates through the workbench 1 and extends to the bottom of the workbench 1. Solenoid valves 83 are installed on the surfaces of the shunt pipes 81 near the bottom of the glue filling table 2.

[0030] During use, when the glue filling of all the transformer coils is completed, control the electric push rods 73 to start simultaneously. At this time, the movable ends of the electric push rods 73 extend, causing the lifting plate 74 to rise accordingly. When the lifting plate 74 rises, the fixing rods 75 rise through the connecting rod 72, and then the glue draining cylinder 71 is driven to rise through the fixing rods 75. By continuously extending the movable ends of the electric push rods 73, the glue draining cylinder 71 is separated from the inside of the placing cylinder 3. At this time, the excess glue on the surface of the transformer coil after glue filling drips into the placing cylinder 3 through the filter holes on the side wall and bottom of the glue draining cylinder 71. Then, control the solenoid valves 83 to open, so that the remaining glue in the placing cylinder 3 enters the glue discharging pipe 82 through the shunt pipe 81, and then is discharged into an external collection bucket through the glue discharging pipe 82 for centralized recycling. By providing the glue draining cylinder 71, the transformer coil after glue filling can be drained in time, preventing excess insulating glue from forming bead-like protrusions on its surface, thereby improving the practicality of the stable glue filling device for the transformer coil.

[0031] Working principle: When the transformer coil stable glue filling device is to be used, the transformer coil is first placed in turn inside the glue filling cylinder 71 located in the placement cylinder 3, and then the drive motor 51 is started to control the movement of the drive mechanism, so that the support plate 55 drives the glue filling mechanism to move above the placement cylinder 3, and then the hydraulic rod 62 is started to drive the glue filling cylinder 64 to move down to the top of the placement cylinder 3 through the connecting plate 63, and then the control valve is opened to allow the glue in the glue storage box 61 to flow out from the glue filling head 66 through the glue filling tube 65 and the glue filling cylinder 64 in turn to stably fill the transformer coil with glue. The driving motor 51 continuously controls the translational movement of the glue filling mechanism so that the glue filling head 66 has finished filling all the transformer coils with glue, and then the vibration motor 41 is started to vibrate The driving mechanism moves, thereby driving the glue filling table 2 to vibrate, so that the glue can evenly and fully penetrate into the gap of the transformer coil. When the glue filling table 2 vibrates, the first shock-absorbing spring 42 and the second shock-absorbing spring 45 can buffer it, ensuring the stability of the glue penetration of the transformer coil. When the operation is completed, the control electric push rod 73 is started at the same time to make the glue draining mechanism move upward. At this time, the glue draining cylinder 71 drives the transformer coil out of the placement cylinder 3, and the excess glue drips into the placement cylinder 3 through the filter holes of the glue draining cylinder 71. Then the solenoid valve 83 is opened to allow the remaining glue in the placement cylinder 3 to enter the glue discharge pipe 82 through the shunt pipe 81, and finally discharged into the external collection bucket through the glue discharge pipe 82 for centralized recycling.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
