Description

Technical Field

[0001] This invention belongs to the field of high-frequency high-voltage transformer technology, and more specifically, relates to a large-capacity dry-type high-frequency high-voltage transformer. Background Technology

[0002] High-frequency transformers are power transformers that operate at frequencies exceeding intermediate frequencies (10kHz). They are mainly used in high-frequency switching power supplies as high-frequency switching power supply transformers, and are also used in high-frequency inverter power supplies and high-frequency inverter welding machines as high-frequency inverter power supply transformers.

[0003] Patent CN215643973U relates to the field of dry-type transformer technology and discloses a large-capacity dry-type high-frequency high-voltage transformer, including a base. A groove is formed on the top of the base, and a placement block is fixedly connected inside the groove. The transformer body is mounted on the top of the placement block. Bidirectional screws are rotatably connected to the inner walls of the left and right sides of the groove. Vertical plates are threaded to both ends of the bidirectional screws, and heat dissipation shells are fixedly installed on opposite sides of the two vertical plates. This large-capacity dry-type high-frequency high-voltage transformer, by rotating the handle, causes the bidirectional screws to rotate, driving the threaded vertical plates at both ends to move relative to each other. This allows the two semi-circular heat dissipation shells to assemble and surround the transformer body. Simultaneously, the two vertical plates cause the tops of two connecting brackets to move closer together, pushing the bottom ends of the connecting brackets down to contact the top of the transformer body, thus fixing the transformer body on the base and ensuring the safe use of the dry-type transformer.

[0004] However, the existing large-capacity dry-type high-frequency high-voltage transformer mentioned above does not provide protection for the surface of the device while clamping the transformer. When an object collides with the surface of the device, it may not only damage the device but also affect the normal use of the transformer. Therefore, a large-capacity dry-type high-frequency high-voltage transformer is needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a large-capacity dry-type high-frequency high-voltage transformer, which solves the technical problem that existing large-capacity dry-type high-frequency high-voltage transformers, while clamping the transformer, do not provide surface protection for the device. When an object collides with the surface of the device, it can not only damage the device but also potentially affect the normal operation of the transformer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a large-capacity dry-type high-frequency high-voltage transformer, comprising a placement plate, a first groove formed on the upper surface of the placement plate, electric push rods fixedly connected to both sides of the first groove, a clamping block fixedly connected to one end of each electric push rod, a plurality of damping spring dampers fixedly connected to the upper surface of each clamping block, a second groove formed on the opposite side of each clamping block, a first connecting rod sleeved in each of the two second grooves, a first baffle and a second baffle fixedly connected to the side of the two first connecting rods away from the second grooves respectively, a third groove formed on the side of the second baffle facing the first baffle, and a second connecting rod fixedly installed on the side of the first baffle facing the second baffle.

[0007] As a preferred embodiment of the present invention, the inner walls of the two clamping blocks are fixedly connected with protective pads, the top end of the damping spring damper is fixedly connected to the lower surface of the protective plate, and the protective plate is provided in two pieces.

[0008] As a preferred embodiment of the present invention, a second baffle is fixedly connected to one side of the second connecting rod, the second connecting rod is disposed opposite the second baffle, and the length of the second connecting rod is the same as the length of the first baffle.

[0009] As a preferred embodiment of the present invention, a first vent hole is provided at equal intervals in the first baffle, the size of the first vent hole is mm, and the arrangement is in rows.

[0010] As a preferred embodiment of the present invention, a second vent hole is provided at equal intervals inside the second baffle, the size of the second vent hole is mm, and the arrangement is in rows.

[0011] As a preferred embodiment of the present invention, the lower surfaces of the first baffle and the second baffle abut against the interior of the placement plate, and the first baffle and the second baffle are arranged horizontally side by side inside the placement plate.

[0012] As a preferred embodiment of the present invention, the lower surface of the placement plate is fixedly connected with support feet, the support feet are fixedly connected to the lower surface of the base plate in a point-like manner, and there are four support feet in total.

[0013] As a preferred embodiment of the present invention, the inner wall of the clamping block has two connecting holes, and the surface of the other clamping block is fixedly connected with a fixing rod. The connecting holes and the fixing rod are positioned relative to each other, and there are two fixing rods.

[0014] This invention provides a large-capacity dry-type high-frequency high-voltage transformer, which has the following beneficial effects:

[0015] 1. By setting up a placement plate, clamping blocks, a first groove, an electric push rod, protective pads, a protective plate, a damping spring vibration damper, connecting holes, and a fixing rod, when the operator places the transformer downwards into the clamping blocks, the electric push rod begins to stretch and control the two clamping blocks to move horizontally relative to each other, completing the clamping and installation of the transformer. This ensures that the installation process of this device is smoother and more efficient. At the same time, through the protective plate and damping spring vibration damper, when an object falls onto this device, the damping spring vibration damper and the protective plate can prevent the object from directly impacting the transformer, providing a certain degree of protection for this device.

[0016] 2. By setting a first baffle, a first vent hole, a second groove, a first connecting rod, a second baffle, and a second vent hole, when the first connecting rod moves into the second groove, the first baffle and the second baffle are connected to the clamping block, which at the same time protects the surface of the transformer. Meanwhile, the first vent hole and the second vent hole enable ventilation and heat dissipation of the device. Attached Figure Description

[0026] Example 1

[0027] Please see Figures 1 to 4This invention provides a technical solution: a large-capacity dry-type high-frequency high-voltage transformer, including a placement plate 1. A first groove 2 is formed on the upper surface of the placement plate 1, allowing for the placement of clamping blocks 4. Electric push rods 3 are fixedly connected to both sides of the first groove 2. When the electric push rods 3 move, the movement of the clamping blocks 4 is synchronously controlled. One end of each electric push rod 3 is fixedly connected to a clamping block 4 via a piston rod 22. By setting the clamping blocks 4, the transformer is clamped during relative movement, preventing the transformer from shaking during use. Multiple damping spring dampers 6 are fixedly connected to the upper surface of each clamping block 4. When an object impacts the device, the damping spring dampers 6... It can play a role in shock absorption and buffering. Each clamping block 4 has a second groove 18 on the opposite side. By setting the second groove 18 and the first connecting rod 15, when the first connecting rod 15 moves into the second groove 18, the connection between the first baffle 16 and the second baffle 10 and this device is completed. The first connecting rod 15 is sleeved in each of the two second grooves 18. The first baffle 16 and the second baffle 10 are respectively fixedly connected on the side of the two first connecting rods 15 away from the second groove. The second baffle 10 has a third groove on the side facing the first baffle 16. The second connecting rod 14 is fixedly installed on the side of the first baffle 16 facing the second baffle 10.

[0028] Among them, the inner walls of the two clamping blocks 4 are fixedly connected with protective pads 5, and the top of the damping spring damper 6 is fixedly connected to the lower surface of the protective plate 7. By setting the protective plate 7, the device can be protected. There are two protective plates 7.

[0029] The second connecting rod 14 is fixedly connected to a second baffle 10 on one side. The second baffle 10 can protect the transformer. The second connecting rod 14 is located opposite the second baffle 10. The length of the second connecting rod 14 is the same as the length of the first baffle 16.

[0030] The first baffle 16 has 28 first vent holes 17 at equal intervals. The size of the first vent holes 17 is 27.5mm and they are arranged in 7 rows.

[0031] The second baffle 10 has 28 second vent holes 11 at equal intervals. The size of the second vent holes 11 is 27.5mm, and they are arranged in 7 rows. By setting the second vent holes 11, air circulation inside and outside the device can be realized, and the device can also be cooled.

[0032] The lower surfaces of the first baffle 16 and the second baffle 10 abut against the interior of the placement plate 1, and the first baffle 16 and the second baffle 10 are arranged horizontally side by side inside the placement plate.

[0033] Among them, the lower surface of the placement plate 1 is fixedly connected with support feet 12. By setting support feet 12, the device is supported and moisture-proofed, and the service life of the device is extended. The support feet 12 are fixedly connected to the lower surface of the base plate 1 in a point-like manner, and there are four support feet 12.

[0034] The clamping block 4 has two connecting holes 8 on its inner wall. By setting the connecting holes 8 and the fixing rod 9, when the fixing rod 9 moves into the connecting hole 8, the connection between the clamping blocks 4 becomes more stable. The surface of another clamping block 4 is fixedly connected with a fixing rod 9. The connecting holes 8 and the fixing rod 9 are set to relative positions, and there are two fixing rods 9.

[0035] The specific usage and function of this embodiment are as follows: When using this device, the operator can place the transformer downwards on the placement plate 1 and push the two clamping blocks 4 horizontally relative to each other by electric telescopic push. At this time, the clamping blocks 4 limit the transformer and prevent the transformer from shaking during use. At the same time, when the fixing rod 9 moves into the connecting hole 8, the connection between the clamping blocks 4 becomes more stable. When an object falls downwards, the protective plate 7 and the damping spring shock absorber 6 buffer and absorb the object, preventing the device from being damaged by a large impact force, which would affect the use of the transformer. At the same time, when the first connecting rod 15 moves into the second groove 18, the connection between the first baffle 16 and the second baffle 10 and the device is completed. The first baffle 16 and the second baffle 10 can protect the surface of the transformer. The first vent 17 and the second vent 11 allow the internal and external air circulation of the device.
