Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a large-capacity oil-immersed amorphous alloy transformer. Background Technology

[0002] Large-capacity oil-immersed amorphous alloy transformers are power transformers that use amorphous alloy as the core material and insulating oil as the cooling and insulating medium, suitable for high-capacity power transmission scenarios. Their core losses are significantly lower than those of traditional silicon steel transformers, exhibiting excellent energy-saving and consumption-reducing characteristics and higher operating efficiency. Large-capacity oil-immersed transformers are typically equipped with an oil conservator.

[0003] Common oil conservator types include open-type, bladder-type, and bellows-type. The bladder-type is the most widely used. A bladder is placed inside the conservator to isolate the oil from the outside air, preventing oxidation or moisture absorption of the transformer's insulating oil. When installing the bladder inside the conservator, because it is flexible and unsupported, the connecting flange at the top of the bladder will tilt synchronously with the bladder's contraction and shifting, making it impossible to automatically align with the mounting holes on the connecting flange at the top of the conservator. This requires multiple workers to work together to repeatedly adjust and straighten the connecting flange at the top of the bladder to align with the connecting flange at the top of the conservator. When adjusting the connecting flange at the top of the bladder inside the conservator, the space within the conservator and the position of the bladder may obstruct the view when aligning the two flanges, making it difficult to visually judge the alignment status, thus increasing the difficulty of aligning the two connecting flanges and increasing the installation time of the bladder. Summary of the Invention

[0004] The purpose of this invention is to provide a high-capacity oil-immersed amorphous alloy transformer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large-capacity oil-immersed amorphous alloy transformer, comprising a transformer body and an oil conservator fixedly installed at one end of the top of the transformer body.

The two slide strips are slidably connected to the two slide rails respectively. Clamping mechanisms are provided on both sides of the vent pipe.

[0008] Preferably, the elastic clamping assembly includes two springs and a connecting bracket. The two springs are respectively sleeved on the outside of their respective guide rods. The connecting bracket is slidably sleeved on the outside of the two guide rods. An arc-shaped clamping plate is fixedly installed on the side of the connecting bracket away from the lifting bracket. The arc-shaped clamping plate cooperates with the vent pipe. The top of the end of the connecting bracket away from the arc-shaped clamping plate cooperates with the inclined surface of the wedge plate.

[0009] Preferably, the fixing mechanism includes a limiting block and a stop block. The limiting block is fixedly installed on one side of the corresponding slide rail. Positioning holes are provided at both ends of the limiting block. The stop block is fixedly installed on one side of the protective frame. Positioning rods are slidably installed at both ends of the stop block. The two positioning rods cooperate with the two positioning holes respectively. A base plate is fixedly installed at the bottom of the two positioning rods. Springs are fixedly installed between the two ends of the bottom of the base plate and the inner wall of the stop block.

[0010] Preferably, the transmission mechanism includes a threaded rod and a limiting rod. The threaded rod is rotatably mounted on one end of the top of the protective frame, and the limiting rod is fixedly mounted on the end of the top of the protective frame away from the threaded rod. An adjusting plate is externally threaded onto the threaded rod. Transmission rods are rotatably mounted on both ends of the bottom of the adjusting plate.

[0011] Preferably, the flipping assembly includes a flipping plate and a top rod. A rotating shaft is fixedly installed inside the flipping plate and is rotatably connected to the protective frame.

[0030] This invention provides a technical solution: such as Figure 1 - Figure 11 The large-capacity oil-immersed amorphous alloy transformer shown includes a transformer body 1 and an oil conservator 2 fixedly installed at one end of the top of the transformer body 1.

A wedge plate 14 is fixedly installed on the top of the two guide rods 13. A lifting bracket 15 is slidably installed on the outside of the two guide rods 13. Guide rods 16 are fixedly installed at both ends inside the lifting bracket 15. An elastic clamping assembly is provided inside the lifting bracket 15.

[0033] The elastic clamping assembly includes two springs 17 and a connecting bracket 18. The two springs 17 are respectively sleeved on the outside of their respective guide rods 16. The connecting bracket 18 is slidably sleeved on the outside of the two guide rods 16. An arc-shaped clamping plate 19 is fixedly installed on the side of the connecting bracket 18 away from the lifting bracket 15. The arc-shaped clamping plate 19 cooperates with the vent pipe 6. The top of the end of the connecting bracket 18 away from the arc-shaped clamping plate 19 cooperates with the inclined surface of the wedge plate 14.

[0034] The fixing mechanism includes a limiting block 20 and a stop block 22. The limiting block 20 is fixedly installed on one side of the corresponding slide rail 10. The limiting block 20 has positioning holes 21 at both ends. The stop block 22 is fixedly installed on one side of the protective frame 9. The stop block 22 has positioning rods 23 slidably installed at both ends. The two positioning rods 23 cooperate with the two positioning holes 21 respectively. The bottom of the two positioning rods 23 is fixedly installed with a base plate 24. The bottom ends of the base plate 24 are fixedly installed with springs 25 between the two ends of the bottom of the base plate 24 and the inner wall of the stop block 22.

[0035] The transmission mechanism includes a threaded rod 26 and a limiting rod 27. The threaded rod 26 is rotatably mounted on one end of the top of the protective frame 9, and the limiting rod 27 is fixedly mounted on the top end of the protective frame 9 away from the threaded rod 26. An adjusting plate 28 is externally threaded onto the threaded rod 26. Transmission rods 29 are rotatably mounted on both ends of the bottom of the adjusting plate 28. The ends of the two transmission rods 29 away from the adjusting plate 28 are rotatably connected to the bottom of their respective lifting brackets 15. Two flipping components are symmetrically arranged on the side of the adjusting plate 28 near the two transmission rods 29.

[0036] The flipping assembly includes a flipping plate 30 and a top rod 33. A rotating shaft 31 is fixedly installed inside the flipping plate 30 and is rotatably connected to the protective frame 9. The side of the top rod 33 away from the flipping plate 30 is fixedly connected to the adjusting plate 28, and the top rod 33 is slidably connected to the mounting bracket 12. A trapezoidal block 32 is fixedly installed on the top of the flipping plate 30 near the top rod 33. The side of the top rod 33 near the flipping plate 30 cooperates with the inclined surface of the trapezoidal block 32. The end of the flipping plate 30 away from the trapezoidal block 32 cooperates with the corresponding base plate 24.

[0037] Hooks 34 are fixedly installed at both ends of the top of capsule 5, and hanging rings 35 are fixedly installed at both ends of the bottom of protective frame 9. The two hanging rings 35 cooperate with the two hooks 34 respectively.

[0038] Working principle: Before installing capsule 5 inside oil pillow 2, first push the two arc-shaped clamping plates 19 to move away from each other, and the two connecting brackets 18 move along their respective guide rods 16. The corresponding springs 17 are compressed. Then, place the vent pipe 6 at the top of capsule 5 between the two arc-shaped clamping plates 19 and place the limiting ring plate 8 on top of the two arc-shaped clamping plates 19. Then, release the two arc-shaped clamping plates 19. Under the action of multiple springs 17, the two arc-shaped clamping plates 19 move closer to each other and are clamped below the limiting ring plate 8. Then, hang the hooks 34 at both ends of the top of capsule 5 inside the two hanging rings 35 respectively to achieve the initial positioning of capsule 5.

[0039] Then, the two sliding bars 11 are respectively aligned with the two slide rails 10. After inserting the two sliding bars 11 into the two slide rails 10, the protective frame 9 is pushed into the oil conservator 2 until the two stop blocks 22 contact the two limit blocks 20. At this point, the protective frame 9 can no longer be pushed and reaches a fixed position. The connecting flange 1 4 and the connecting flange 2 7 are aligned with each other, and the multiple positioning rods 23 are also aligned with the multiple positioning holes 21. Then, the threaded rod 26 is rotated, and under the action of the limit rod 27, the adjusting plate 28 moves to one side of the vent pipe 6. While the adjusting plate 28 moves, it drives the two transmission rods 29 to move synchronously. The two transmission rods 29 then push their respective lifting brackets 15 to move steadily upward along the corresponding guide rods 13. While the two lifting brackets 15 move upward, they drive their respective connecting brackets 18 and the arc-shaped clamping plates 19 to move upward synchronously. The two arc-shaped clamping plates 19 then drive the vent pipe 6 upward. The movement causes the connecting flange 2 7 to gradually move upward towards the connecting flange 1 4. As the two connecting brackets 18 move upward, they gradually approach their respective wedge plates 14. As the two connecting brackets 18 continue to move upward, one end of each connecting bracket 18 contacts the inclined surface of the two wedge plates 14. The two wedge plates 14 press the two connecting brackets 18 together, and the positions of the two arc-shaped clamping plates 19 are fixed and cannot move horizontally. This avoids the two arc-shaped clamping plates 19 from moving horizontally due to not being fixed during the fixing of the connecting flange 2 7. By using the clamping mechanism to clamp the vent pipe 6, after the entire protective frame 9 is pushed into the fixed position of the oil conservator 2, the positions of the connecting flange 2 7 and the connecting flange 1 4 at the top of the capsule 5 correspond to each other. There is no need to repeatedly adjust the position of the connecting flange 2 7, thereby reducing the difficulty of aligning the connecting flange 2 7 and the connecting flange 1 4, and thus reducing the installation time of the capsule 5.

[0040] While rotating the threaded rod 26 pushes the adjusting plate 28 to move, the two push rods 33 move synchronously. The two push rods 33 act on the inclined surfaces of the two trapezoidal blocks 32 respectively. The two trapezoidal blocks 32 are driven by force to rotate their corresponding flip plates 30 along their respective rotation axes 31. The ends of the two flip plates 30 away from their respective trapezoidal blocks 32 act on their respective fixing mechanisms. The movement process of one of the fixing mechanisms is as follows: Under the action of the corresponding flip plates 30, the base plate 24 drives the two positioning rods 23 to move upward synchronously, and the two springs 25 are stretched by force. The two positioning rods 23 move upward and insert into their respective... The positioning hole 21 is inside; the movement of the other fixing mechanism is the same as described above. At this time, the two stop blocks 22 are connected to the two limit blocks 20 respectively, thereby fixing the protective frame 9 to the bottom of the two slide rails 10. By setting the fixing mechanism, while operating the transmission mechanism, the transmission mechanism also acts on the fixing mechanism, so that the fixing mechanism realizes the connection between the two slide rails 10 and the protective frame 9, thereby fixing the protective frame 9 inside the oil pillow 2, preventing the protective frame 9 from shaking inside the oil pillow 2, and eliminating the need for staff to spend time fixing the protective frame 9, saving the time of fixing the capsule 5 inside the oil pillow 2.

[0041] After the protective frame 9 is fixed, the two sealing side plates 3 are fixed to both sides of the oil reservoir 2 for subsequent use.
