Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer core assembly structure and its usage method. Background Technology

[0002] The iron core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating varnish. The existing iron core is complicated to assemble, resulting in low assembly efficiency. After assembly, the iron core needs to be aligned with the installation position before it is fixed, which consumes a lot of manpower.

[0003] As described in application number 202122804352.0, an assembly structure for a power transformer core is provided. This structure includes a lead screw, a moving column, a piston plate, a spring, a connecting pipe, a second piston cylinder, a first piston cylinder, a fixed column, and fixed holes. Two lead screws are inserted into two first threaded holes. Then, the two lead screws are rotated counterclockwise, causing them to move downwards and into two second threaded holes. This moves the two moving columns downwards, which in turn move the two first piston plates downwards and compress the two springs. The two first piston cylinders then move the four fixed columns outwards, completing the installation of several first cores and several second cores. This allows for quick installation and disassembly of the device.

[0004] Based on the search of the above information, it can be seen that in the existing iron core assembly technology, it is still necessary to open mounting holes on the surface of the iron core and to use bolts and nuts to assemble and fix the iron core. This operation is relatively cumbersome and not conducive to the rapid assembly, disassembly and maintenance of the iron core. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a transformer core assembly structure and its usage method, which solves the problem that existing core assembly technologies require the use of bolts and nuts for core assembly and fixation, which is cumbersome and not conducive to rapid core assembly, disassembly, and maintenance.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a transformer core assembly structure, comprising a U-shaped support, a plurality of first cores, a coil sleeved on the first cores, and a plurality of second cores used in conjunction with the first cores. The top of the U-shaped support is provided with a cover plate, and the bottom of the cover plate has grooves adapted to the plurality of second cores. The surface of the U-shaped support is provided with assembly slots adapted to the plurality of first cores. The interior of the U-shaped support is provided with a U-shaped assembly channel, which communicates with the assembly slots. The U-shaped assembly channel includes two vertical sections and one horizontal section, which communicate with each other, and the horizontal section communicates with the assembly slots. The interior of the U-shaped assembly channel is provided with two core clamping members, which are located on both sides of the first cores. The bottom of the cover plate is fixedly connected to two pins adapted to the U-shaped assembly channel, and the pins and the U-shaped support are fixedly engaged by elastic elements.

[0009] The present invention is further configured such that: the elastic element includes a piston plate, a pin is fixedly connected to one side of the piston plate, and a first spring is fixedly connected to the other side of the piston plate.

[0010] The present invention is further configured such that: blind holes are provided on both the front and rear sides of the pin plate, the piston plate is slidably installed inside the blind holes, one end of the first spring is fixedly connected to one side of the inner cavity of the blind hole, and pin holes adapted to the pin are provided on both the front and rear sides of the U-shaped support.

[0011] The front and rear sides of the inner cavity of the U-shaped assembly channel are provided with slots that are adapted to the pin, and the pin hole is connected to the slot.

[0012] The present invention is further configured such that: the iron core clamping component includes a pressing plate and a clamping block; a push plate is fixedly connected to the bottom of the pressing plate by a connecting rod; a linkage plate is rotatably mounted on the bottom of the push plate by a bearing; one side of the linkage plate is rotatably connected to one side of the clamping block by a rotating block; and an inclined groove is provided on the other side of the clamping block.

[0013] The present invention is further configured such that: the clamping block is slidably installed in the horizontal part of the inner cavity of the U-shaped assembly channel, and the squeezing plate and the linkage plate are both slidably installed in the vertical part of the inner cavity of the U-shaped assembly channel.

[0014] The present invention is further configured such that: a positioning plate is fixedly connected inside the U-shaped assembly channel, the positioning plate is disposed between the extrusion plate and the linkage plate, and a connecting rod is disposed through the positioning plate; a second spring is sleeved on the outer periphery of the connecting rod, and the two ends of the second spring are respectively in contact with the opposite side of the extrusion plate and the positioning plate.

[0015] The present invention is further configured such that: heat dissipation grooves are provided on the top of the cover plate, the bottom of the U-shaped support base, and the front and rear sides, and gripping grooves communicating with the grooves are provided on the front and rear sides of the cover plate.

[0016] This invention also discloses a method for using a transformer core assembly structure, specifically including the following steps:

[0017] Step 1, Pre-assembly: Stack several first iron cores and place them into the assembly slot. Sleeve the coil around the outer periphery of several first iron cores. After the cover plate is inverted, stack several second iron cores and place them into the groove.

[0018] Step 2, Assembly: After initially fixing several second iron cores by inserting fingers through the gripping groove, lift the cover plate and insert the two pin plates into the U-shaped assembly channel. As the pin plates move downward, they drive the pins to move downward along the groove. The pins drive the piston plate to squeeze the first spring until the pin moves to the pin hole. The first spring returns to its original position and pushes the piston plate to insert the pin into the pin hole. At this time, the pin plates no longer descend, and the top of the second iron core is in contact with the top of the first iron core.

[0019] Step 3, Bottom clamping: During the descent of the pin plate, it comes into contact with the extrusion plate and is squeezed. The extrusion plate drives the push plate to move downward through the connecting rod. During this process, the extrusion plate squeezes the second spring. The push plate pushes the clamping block to move closer to the first iron core through the linkage plate. During this process, the inclined slot squeezes and clamps several first iron cores.

[0020] (III) Beneficial Effects

[0021] This invention provides a transformer core assembly structure and its usage method. It has the following beneficial effects:

[0022] (1) The present invention provides installation space for the first iron core by setting a U-shaped support base, and provides installation space for the second iron core by setting a cover plate and a groove. With the cooperation of the U-shaped assembly channel, pin plate and elastic element, the U-shaped support base and cover plate can be conveniently fixed. Furthermore, with the setting of the iron core clamping element, the first iron core can be clamped and positioned during the fixing process of the cover plate. This ensures a stable connection between the first and second iron cores without the need to make holes in the first and second iron cores. The convenient installation method provides convenient conditions for the disassembly and maintenance of the iron core.

[0023] (2) The present invention utilizes the cooperation of the extrusion plate, connecting rod, push plate, linkage plate, clamping block and inclined slot to extrude the extrusion plate during the descent of the pin block, thereby causing the linkage plate to push the clamping block closer to the first iron core, and causing the inclined slot to extrude and position several first iron cores, ensuring close contact between several first iron cores. With the cooperation of the second spring and positioning plate, the extrusion plate can be reset during the process of the pin plate disengaging from the extrusion plate, thus providing a guarantee for the convenient disassembly and assembly of the first iron core.

[0043] Example 2

[0044] This embodiment is an improvement on the previous embodiment. A transformer core assembly structure further includes heat dissipation grooves 26 on the top of the cover plate 5, the bottom of the U-shaped support 1, and the front and rear sides, to facilitate heat dissipation of the first core 2 and the second core 4 during operation.

[0045] As a preferred option, in order to facilitate the stable assembly of the second iron core 4, the front and rear sides of the cover plate 5 are provided with gripping grooves 27 that communicate with the grooves 6.

[0046] The advantage of Embodiment 2 over Embodiment 1 is that it can also provide sufficient space for heat dissipation of the first iron core 2 and the second iron core 4.

[0047] A method for using a transformer core assembly structure specifically includes the following steps:

[0048] Step 1, Pre-assembly: Stack several first iron cores 2 and place them into the assembly slot 7. Put the coil 3 around the outer periphery of several first iron cores 2. After the cover plate 5 is inverted, stack several second iron cores 4 and place them into the groove 6.

[0049] Step 2, Assembly: After the fingers pass through the gripping groove 27 to initially fix several second iron cores 4, pick up the cover plate 5 and insert the two pin plates 10 into the U-shaped assembly channel 8. As the pin plates 10 move downward, they drive the pins 13 to move downward along the groove 17. The pins 13 drive the piston plate 12 to squeeze the first spring 14 until the pins 13 move to the pin hole 16. The first spring 14 returns to its original position and pushes the piston plate 12 to insert the pins 13 into the pin hole 16. At this time, the pin plates 10 no longer descend, and the top of the second iron core 4 is in contact with the top of the first iron core 2.

[0050] Step 3, Bottom clamping: During the descent of the pin plate 10, it comes into contact with the pressing plate 18 and is pressed. The pressing plate 18 drives the push plate 21 to move downward through the connecting rod 20. During the process, the pressing plate 18 presses the second spring 25. The push plate 21 pushes the clamping block 19 to move closer to the first iron core 2 through the linkage plate 22. During the process, the inclined slot 23 presses and clamps several first iron cores 2.
