Description

Technical Field

[0001] This utility model relates to the field of transformers, and in particular to a transformer with lightning protection function. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).

[0003] Transformers can be classified according to their uses as follows: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type transformers, test transformers, angle transformers, high-current transformers, excitation transformers, etc.

[0004] In the prior art, a Chinese utility model patent with publication number "CN217881062U" and patent name "a transformer with lightning protection function" discloses a transformer with lightning protection function. The patent describes a technical solution that "by setting up a lightning protection mechanism, during the installation of the lightning protection mechanism, the grounding component can be screwed into the ground to contact the ground grid. In daily use, if struck by lightning, the lightning rod first contacts the lightning, and after being stably guided by the lightning ball, impedance support rod and support, the current flows into the ground grid through the lightning wire and the grounding component, thus achieving the effect of lightning protection".

[0005] However, in actual use, because the lightning rod is fixed to the top surface of the protective top plate, it is difficult to disassemble and replace the lightning rod in a timely manner after it is damaged by lightning. Furthermore, during the transportation and movement of the transformer, the vertical lightning rod is prone to bending, breaking and damage under the impact or pressure of external forces, which will affect the lightning protection effect on the transformer.

[0006] Therefore, this utility model proposes a transformer with lightning protection function. Utility Model Content

[0007] The main purpose of this utility model is to provide a transformer with lightning protection function, which can effectively solve the problems in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A transformer with lightning protection function includes a transformer body. A set of symmetrical lightning protection mechanisms is provided on the top surface of the transformer body. Each lightning protection mechanism includes a concave seat, a fixed ring, a movable disc, a limiting rod, a compression spring, a T-shaped rotating seat, an internally threaded sleeve, a lightning rod, and a grounding wire. A set of symmetrical concave seats is fixedly connected to the top surface of the transformer body. The fixed ring is fixedly connected to the front wall of the concave seat via side plates on both sides of the rear wall. The movable disc is movably connected to the fixed ring via a movable rod on the front wall. The compression spring is sleeved outside the movable rod and fixedly connected between the movable disc and the fixed ring. The limiting rod is fixedly connected to the rear wall of the movable disc. The T-shaped rotating seat is movably connected to the concave seat via rotating rods at the front and rear ends. The internally threaded sleeve is fixedly connected to the top of the T-shaped rotating seat via top plates on both sides of the bottom surface. The lightning rod is fixedly connected to the internally threaded sleeve via a threaded connecting post at the bottom end. The grounding wire is fixedly connected to the bottom end of the lightning rod and passes through the threaded connecting post.

[0010] Preferably, the concave seat is fixedly installed on the top surface of the transformer body, and rotating holes are respectively opened on the front and rear side walls inside the concave seat.

[0011] Preferably, rotating rods are fixedly installed at the front and rear ends of the T-shaped swivel base, and the rotating rods are movably installed in the rotating holes. A limit groove is also provided on the front wall of the front rotating rod.

[0012] Preferably, a set of symmetrical top plates are fixedly installed on the bottom surface of the internal threaded sleeve, and the top plates are fixedly installed on the top surface of the T-shaped swivel. A threaded connecting post is fixedly installed at the bottom end of the lightning rod, and the threaded connecting post is threadedly connected to the internal threaded sleeve. A lead wire hole is opened on the bottom surface of the threaded connecting post. The grounding wire is fixedly installed at the bottom end of the lightning rod and passes through the lead wire hole, and the other end of the grounding wire is connected to the ground.

[0013] Preferably, a set of symmetrical side plates are fixedly installed on the rear wall of the fixing ring, and the side plates are fixedly installed on the front wall of the concave seat, and a sliding groove is provided on the inner side wall of the side plate.

[0014] Preferably, sliders are fixedly installed on both sides of the movable disk, and the sliders are movably installed in the slide groove. A limit rod is fixedly installed on the rear wall of the movable disk and inserted into the limit groove. A movable rod is fixedly installed on the front wall of the movable disk and inserted into the fixed ring. A compression spring is fitted on the outside of the movable rod and fixedly installed between the fixed ring and the opposite wall of the movable disk. A pull ring is also fixedly installed at the front end of the movable rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the lightning protection mechanism works in conjunction with the transformer body. When the transformer body is being moved, pulling the pull ring moves the limiting rod out of the limiting groove, causing the lightning rod to rotate 90 degrees inward. Releasing the pull ring allows the movable disc to be pushed back into the limiting groove by the elastic reset action of the compression spring. The lightning rod is then folded by rotating the T-shaped swivel, thus preventing damage to the lightning rod caused by external factors during transformer body movement. When the transformer body is in use, the lightning rod is rotated to a vertical position. When struck by lightning, the current is conducted into the ground through the grounding wire, providing lightning protection for the transformer body. If the lightning rod is damaged by lightning, it can be rotated to unscrew the threaded connecting post from the internal threaded sleeve, allowing for easy disassembly and replacement. This facilitates timely disassembly and replacement of the damaged lightning rod. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 - Figure 3As shown, a transformer with lightning protection function includes a transformer body 1. A set of symmetrical lightning protection mechanisms 2 is provided on the top surface of the transformer body 1. Each lightning protection mechanism 2 includes a concave seat 3, a fixed ring 6, a movable disc 8, a limiting rod 10, a compression spring 12, a T-shaped rotating seat 14, an internally threaded sleeve 18, a lightning rod 19, and a grounding wire 20. A set of symmetrical concave seats 3 is fixedly connected to the top surface of the transformer body 1. The fixed ring 6 is fixedly connected to the front wall of the concave seat 3 via side plates 5 on both sides of the rear wall. The movable disc 8 is connected to the fixed ring 3 via a movable rod 11 on the front wall. Ring 6 is movably connected, and compression spring 12 is sleeved on the outside of movable rod 11 and fixedly connected between movable disk 8 and fixed ring 6. Limiting rod 10 is fixedly connected to the rear end wall of movable disk 8. T-shaped swivel seat 14 is movably connected to concave seat 3 through rotating rod 15 at the front and rear ends. Internal threaded sleeve 18 is fixedly connected to the top of T-shaped swivel seat 14 through top plates 17 on both sides of the bottom surface. Lightning rod 19 is fixedly connected to internal threaded sleeve 18 through threaded connecting post 21 at the bottom end. Grounding wire 20 is fixedly connected to the bottom end of lightning rod 19 and passes through threaded connecting post 21.

[0023] like Figure 3 As shown, the concave seat 3 is fixedly installed on the top surface of the transformer body 1, and the front and rear side walls inside the concave seat 3 are respectively provided with rotating holes 4. The rotating holes 4 provided inside the front and rear side walls inside the concave seat 3 are used to cooperate with the rotating rod 15 to realize the rotation operation.

[0024] like Figure 3 As shown, rotating rods 15 are fixedly installed at the front and rear ends of the T-shaped rotator 14, and the rotating rods 15 are movably installed in the rotating hole 4. A limiting groove 16 is also provided on the front wall of the front rotating rod 15. After the rotating rods 15 at the front and rear ends of the T-shaped rotator 14 rotate in the rotating hole 4, they can drive the lightning rod 19 to achieve a flipping operation. The limiting groove 16 provided on the front wall of the front rotating rod 15 is used to cooperate with the limiting rod 10 to limit the rotation of the rotating rod 15.

[0025] like Figure 3As shown, a set of symmetrical top plates 17 are fixedly installed on the bottom surface of the internal threaded sleeve 18, and the top plates 17 are fixedly installed on the top surface of the T-shaped swivel 14. A threaded connecting post 21 is fixedly installed at the bottom end of the lightning rod 19, and the threaded connecting post 21 is threadedly connected to the internal threaded sleeve 18. A lead wire hole 22 is opened on the bottom surface of the threaded connecting post 21. The grounding wire 20 is fixedly installed at the bottom end of the lightning rod 19 and passes through the lead wire hole 22. The other end of the grounding wire 20 is connected to the ground, thus connecting the threaded connection at the bottom end of the lightning rod 19. The column 21 is screwed into the internal threaded sleeve 18 and threaded together, which allows the lightning rod 19 to be quickly installed on the transformer body 1 for use. This makes it easy to disassemble and replace the lightning rod 19 in time if it is damaged. The lead hole 22 on the bottom surface of the threaded connection column 21 makes it easy to lead out the grounding wire 20 at the bottom of the lightning rod 19 and make it contact with the ground. This allows the lightning rod 19 to release the current into the ground through the grounding wire 20 after being struck by lightning, thereby providing lightning protection for the transformer body 1.

[0026] like Figure 3 As shown, a set of symmetrical side plates 5 are fixedly installed on the rear wall of the fixed ring 6, and the side plates 5 are fixedly installed on the front wall of the concave seat 3. A sliding groove 7 is provided on the inner side wall of the side plate 5. The fixed ring 6 is used to cooperate with the movement of the movable rod 11, and the sliding groove 7 on the inner side wall of the side plate 5 is used to cooperate with the sliding of the sliders 9 on both sides of the movable disk 8.

[0027] like Figure 3 As shown, sliders 9 are fixedly installed on both sides of the movable plate 8, and the sliders 9 are movably installed in the slide groove 7. A limit rod 10 is fixedly installed on the rear wall of the movable plate 8, and the limit rod 10 is inserted into the limit groove 16. A movable rod 11 is fixedly installed on the front wall of the movable plate 8, and the movable rod 11 is inserted and installed together with the fixed ring 6. A compression spring 12 is fitted on the outside of the movable rod 11, and the compression spring 12 is fixedly installed between the fixed ring 6 and the opposite wall of the movable plate 8. A pull ring 13 is also fixedly installed at the front end of the movable rod 11. When the transformer body 1 is moved, the pull ring 13 is pulled to move the limit rod 11. After the lightning rod 19 is moved out of the limiting groove 16 and rotated 90 degrees inward, the pulling force of the pull ring 13 is released. Under the elastic restoring force of the compression spring 12, the movable plate 8 is pushed to move backward. The movable rod 11 passes through the fixed ring 6, and the sliders 9 on both sides of the movable plate 8 slide in the sliding groove 7 until the limiting rod 10 is inserted into the limiting groove 16. In this way, the lightning rod 19 can be rotated and limited, and the folding operation of the lightning rod 19 can be completed. By folding the lightning rod 19, the problem of damage and unusability of the lightning rod 19 caused by external factors during the transportation and movement of the transformer body 1 can be prevented.

[0028] It should be noted that this utility model is a transformer with lightning protection function. When the transformer body 1 is being moved, manually pulling the pull ring 13 will cause the movable rod 11 to move forward from inside the fixed ring 6. The movable rod 11 will cause the movable plate 8 to move between the side plates 5. The sliders 9 installed on both sides of the movable plate 8 will slide in the grooves 7 opened on the inner side wall of the side plate 5, and force the compression spring 12, which is fitted outside the movable rod 11 and fixed between the fixed ring 6 and the movable plate 8, to retract. Continue pulling the pull ring 13 until the limiting rod 10 installed on the rear wall of the movable plate 8 moves out of the limiting groove 16 opened on the front wall of the front rotating rod 15 of the T-shaped rotating seat 14, and maintain the pulling force on the pull ring 13. Use the other hand to rotate the lightning rod 19 inward by 90 degrees. When rotating, the T-shaped rotating seat 14 moves forward and backward. The rotating rod 15 installed at the end will rotate within the rotating holes 4 opened on the front and rear side walls of the recessed seat 3 on the top surface of the transformer body 1. After the vertical lightning rod 19 flips to a horizontal position, the pulling force of the pull ring 13 is released, and the compression spring 12 will extend and return to its original position. The compression spring 12 will push the movable plate 8 backward, and the movable rod 11 will move backward within the fixed ring 6 until the limiting rod 10 on the rear wall of the movable plate 8 is inserted into the limiting groove 16. This will restrict the rotation of the rotating rod 15 and limit the flipping of the lightning rod 19, thereby completing the folding operation of the lightning rod 19. By folding the lightning rod 19, the problem of the lightning rod 19 being damaged and unusable due to external factors during the transportation and movement of the transformer body 1 can be avoided, ensuring the normal use of the lightning rod 19 in the future.

[0029] When the lightning rod 19 is needed, by pulling the pull ring 13 to move the limiting rod 10 out of the limiting groove 16, the flipping restriction on the lightning rod 19 is released. After the lightning rod 19 is flipped 90 degrees outward to a vertical position, the pull ring 13 is released and the limiting rod 10 is reinserted into the limiting groove 16 under the force of the compression spring 12. The lightning rod 19 can then be fixed and used. When the transformer body 1 is struck by lightning, the lightning rod 19 will be struck by lightning in advance. The lightning current is guided to the lightning rod 19 through the tip discharge and flows rapidly into the ground along the lightning rod 19 and the grounding wire 20 installed at its bottom. This process effectively disperses the lightning energy to the ground, preventing the transformer body 1 from being damaged by direct lightning strikes and enabling the transformer body 1 to have lightning protection function.

[0030] When the lightning rod 19 is damaged by a lightning strike, the threaded connecting post 21 installed at the bottom of the lightning rod 19 is rotated to unscrew the threaded sleeve 18 installed at the top of the T-shaped swivel seat 14 through the top plate 17. In this way, the lightning rod 19 can be quickly removed from the top surface of the transformer body 1. The grounding wire 20 installed at the bottom of the new lightning rod 19, which passes through the lead hole 22 opened on the bottom surface of the threaded connecting post 21, is passed through the threaded sleeve 18. Then the threaded connecting post 21 is screwed into the threaded sleeve 18 and threaded together with it. This completes the installation and replacement of the lightning rod 19. In this way, when the lightning rod 19 is damaged, it is easy to disassemble and replace it in time to ensure the lightning protection function of the transformer body 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
