Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an oil-immersed transformer structure. Background Art

[0002] A transformer is a static electrical device, mainly used to convert a certain value of electrical energy into other values ​​of electrical energy. It mainly works based on the principle of electromagnetic induction and realizes the conversion of electrical energy by changing the AC voltage. The transformer plays an important role in the power system and is the core equipment of the step-up or step-down substation. It is mainly used in the transmission and distribution network to reduce voltage and isolate. It is also an electrical device for raising and lowering voltage and distributing electrical energy in industrial and agricultural production. In addition, transformers are also widely used in transportation, communications and other fields, and are key equipment for power transmission and distribution.

[0003] At present, most oil-immersed transformers are installed outdoors. The exterior and oil seals of existing oil-immersed transformers are not effectively protected. During use, they are easily impacted by external forces, causing the oil seals to rupture and transformer oil to leak. At the same time, the internal coils and cores may be deformed or misaligned, making the transformer unable to be used normally. In severe cases, power accidents may occur.

[0004] In order to solve the above problems, the Chinese utility model patent with publication number CN218384729U discloses an oil-immersed transformer protection structure, which buffers and offsets the impact force through the rebound force of the spring. A small amount of impact afterwave will indirectly act on the transformer, which can be completely eliminated through the hydraulic damper. The different force and deformation directions of the springs on the left and right sides can play a mutual restraint role, so that the spring will not jump repeatedly, thereby protecting the transformer well, not easy to be damaged, and can be used normally.

[0005] During actual use of the above-mentioned oil-immersed transformer protection structure, the oil-immersed transformer will shake during operation, which may cause the internal components and connectors of the transformer to loosen or wear, increasing the risk of mechanical failure. At the same time, the shaking will cause the windings and insulation structure inside the transformer to be impacted, reducing the stability of the internal equipment operation and affecting the working performance of the transformer.

[0040] The three buffer components all include two first shaft supports 4, the two first shaft supports 4 are welded and fixed to the bottom of the movable plate 3, two first push rods 5 are installed inside the two first shaft supports, and multiple first push rods 5 are movably connected to the inside of the first shaft supports 4, one end of the two first push rods 5 is fixedly connected to a sliding block 6, one side of the two sliding blocks 6 is installed with a rubber buffer column 7, a sliding rod 8 is installed outside the two sliding blocks 6 and the rubber buffer column 7, the two sliding blocks 6 are slidably connected to the inside of the sliding rod 8, a second push rod 9 is installed between the multiple first push rods 5, and an insert rod 10 is inserted at one end of the multiple first push rods 5 and the second push rod 9.

A plurality of hydraulic rods 14 are fixedly connected inside the shell 2. The shaking of the transformer body 1 drives the movable plate 3 to move, and the movable plate 3 drives the plurality of first push rods 5 to push the two sliding blocks 6 to move through the first shaft support 4. The two sliding blocks 6 are used to slide inside the sliding rod 8 to extrude the rubber buffer column 7, which can buffer the shaking of the movable plate 3. At the same time, the two first shaft supports 4 push the extrusion plate 12 downward through the second push rod 9, and then the extrusion plate 12 is used to extrude the rubber pad 13 to slow down the downward impact of the movable plate 3.

[0041] As attached Figure 3 As shown, a heat dissipation net 15 is installed on the front side of the transformer body 1, and the heat dissipation net 15 is fixedly connected to the front side of the transformer body 1. Two heat dissipation fans 16 are installed inside the heat dissipation net 15, and the two heat dissipation fans 16 are fixedly connected to the inside of the heat dissipation net 15 by screws. The air inside the transformer body 1 can be convected with the outside through the two heat dissipation nets 15, which is convenient for the heat wave inside the transformer body 1 to contact with the external air, and the temperature inside the transformer body 1 is effectively reduced.

[0042] As attached Figure 5 As shown, sound-absorbing boxes 17 are installed on both sides of the transformer body 1, and first sound-absorbing cottons 18 are installed inside the two sound-absorbing boxes 17. Silencing panels 19 are installed on one side of the two first sound-absorbing cottons 18, and second sound-absorbing cottons 20 are installed on one side of the two sound-absorbing panels 19. The two first sound-absorbing cottons 18 can absorb the noise on both sides of the transformer body 1, the two sound-absorbing panels 19 can reduce the noise of the transformer body 1 during operation, and the two second sound-absorbing cottons 20 can reduce the impact of noise on the surrounding environment.

[0046] The use process of the utility model is as follows: through the mutual cooperation between various structures, the transformer body 1 can be installed and fixed by multiple supporting bases 26. When the transformer body 1 is running and shaking, the transformer body 1 drives the movable plate 3 to move, so that the movable plate 3 drives the two first shaft supports 4 to move downward, and the two first shaft supports 4 move downward to drive the two first push rods 5 to push the sliding block 6 to slide inside the sliding rod 8, so that the two sliding blocks 6 squeeze the rubber buffer column 7 to buffer the shaking of the transformer body 1. At the same time, the two first shaft supports 4 drive the two second push rods 9 to push the extrusion plate 12 to move downward, so that the extrusion plate 12 squeezes the rubber pad 13 downward to slow down the impact of the transformer body 1, and then the multiple hydraulic rods 14 are used to slow down the movement of the movable plate 3 Under the impact, when the transformer body 1 generates heat during internal operation, the heat sink 21 on the left and right sides of the transformer body 1 can absorb the heat inside the transformer body 1 and quickly transfer it to the surrounding air, so that the heat can be quickly dissipated, ensuring that the transformer operates within a normal temperature range, and then the two cooling fans 16 are started. The two cooling fans 16 convect the air inside the transformer body 1 with the external air, which can effectively reduce the internal temperature of the transformer body 1. At the same time, the sound-absorbing boxes 17 on both sides of the transformer body 1 can reduce the noise of the transformer body 1 during operation. The first sound-absorbing cotton 18 absorbs the noise of the shaking surface of the transformer body 1, and the noise is reduced by two sound-absorbing panels 19. Finally, the noise of the transformer body 1 can be further reduced by two second sound-absorbing cottons 20.
