Description

Technical Field

[0001] The invention relates to the technical field of oil-immersed transformers, in particular to a low-noise and environment-friendly oil-immersed transformer. Background Art

[0002] Low-noise and environmentally friendly oil-immersed transformer is a transformer that is optimized based on the traditional oil-immersed transformer and focuses on noise control and environmental friendliness.

[0003] The patent with patent announcement number CN222071681U involves a low-noise, environmentally friendly oil-immersed transformer, including a transformer body, a water-cooled heat dissipation component and a cooling oil circulation component. The cooling oil circulation component is horizontally installed on the top of the transformer body, and the water-cooled heat dissipation component is vertically installed on one side of the cooling oil circulation component; the cooling oil circulation component includes a shell, a heat dissipation element, a pipeline A, a circulation pump B, a liquid storage tank, a pipeline B and a pipeline C. The patent adopts a combination of air cooling and water cooling for heat dissipation. The two heat dissipation methods cooperate with each other to greatly improve the heat dissipation effect while ensuring the production and use costs. The heat dissipation element is located in the cooling circulation path of the water-cooled heat dissipation component. Its structure, combined with water-cooled auxiliary heat dissipation, can greatly improve the heat dissipation effect. During the circulation process, it can also achieve a self-cleaning effect on the impurities and dust on the surface of the heat dissipation element, achieving maintenance-free.

[0004] In the above patent, a combination of air cooling and water cooling is used for heat dissipation. The two heat dissipation methods cooperate with each other, which can greatly improve the heat dissipation effect while ensuring the production and use costs. However, when the transformer is operating, it will shake, causing the devices inside the transformer to contact and collide with each other, resulting in abnormal noise, causing noise nearby, and causing noise pollution.

[0008] According to the above technical scheme, the supporting device includes: a sliding block, a triangular pad block, a load-bearing block, a fixed block, a supporting block, a baffle plate 1, a V-shaped spring piece and a baffle plate 2.

[0014] The present invention provides a low-noise, environmentally friendly oil-immersed transformer, which has the following beneficial effects: (1) This invention, after the free end of the elastic telescopic rod moves toward the bottom, it drives the insulating seat to move toward the top through its own elastic reset. The movement of the insulating seat toward the top will drive the transformer body to move toward the top, reducing the shaking amplitude of the transformer body itself and improving the stability of the device during operation. The movement of the connecting cross plate will drive the reset spring to transfer the shaking generated by the transformer body to the damping ball, further reducing the vibration degree of the transformer body itself, preventing the internal shaking of the transformer body from causing some devices to contact and collide with each other and produce noise, thereby reducing decibels and noise pollution.

[0015] (2) In the present invention, the support block moves toward the top, which drives the rubber pad to move toward the top. After the rubber pad moves, it contacts the transformer body, thereby supporting the transformer body when the transformer body moves toward the bottom, thereby improving the stability of the device during operation. After the triangular pad moves, it no longer contacts the support block, so that the supporting device automatically supports the transformer body through the amplitude of the transformer body, thereby improving the practicality of the device.

[0016] (3) The invention, through the movement of the rotating hook, will contact the fixed hook and be limited by the fixed hook, so that when the sliding block moves in the direction away from the fixed block, the elasticity of the torsion spring is not released, and the support block cannot move to the bottom, thereby preventing the sliding block from being unable to be successfully reset by the V-shaped spring piece due to excessive resistance between the support block and the sliding block when the sliding block moves in the direction away from the fixed block, thereby ensuring the continuity of the device during operation. The limit block is blocked by the arc rod and the cylinder so that the limit block cannot move to the bottom, so that after the fixed hook contacts the rotating hook, the fixed hook will only push the rotating hook to move in the direction of the hydraulic rod, and will not be limited when the rotating hook rotates to the top, thereby improving the practicality of the device.

The two return springs 16 are fixedly mounted on the side of the connecting horizontal plate 13 close to each other. The damping ball 15 is connected to the connecting horizontal plate 13 through the return spring 16, which further slows down the vibration degree of the transformer body 2 itself, prevents the internal shaking of the transformer body 2 from causing some devices to contact and collide with each other to make noise, and reduces decibels and noise pollution.

[0022] When the present embodiment is working: when the amount of insulating oil inside the transformer body 2 is reduced, the insulating oil stored in the oil pillow 5 flows into the transformer body 2 and replenishes the amount of insulating oil inside the transformer body 2, and the insulating oil flows to the inside of the heat sink 3 and dissipates heat, and the heat sink 4 dissipates heat inside the transformer body 2, so as to ensure that the temperature inside the transformer body 2 is within the normal temperature and the transformer body 2 works normally.

The connecting cross plate 13 is in contact with the sliding block 1701, so that the transformer body 2 is supported when the transformer body 2 moves toward the bottom, thereby improving the stability of the device during operation; when the connecting cross plate 13 moves in a direction away from the sliding block 1701, the connecting cross plate 13 is no longer in contact with the sliding block 1701 after moving, and the baffle plate 1706 is driven to move in the direction of the connecting cross plate 13 through the V-shaped spring piece 1707 reset; the movement of the baffle plate 1706 will drive the sliding block 1701 to move in a direction away from the connecting cross plate 13; the movement of the sliding block 1701 will drive the triangular pad 1702 to move in a direction away from the connecting cross plate 13; the triangular pad 1702 is no longer in contact with the supporting block 1705 after moving, so that the supporting device automatically supports the transformer body 2 through the amplitude of the transformer body 2, thereby improving the practicability of the device.

[0030] The movement of the support block 1705 toward the top will drive the sliding seat 1805 toward the top, the movement of the sliding seat 1805 toward the top will drive the vertical plate 1806 toward the top, the movement of the vertical plate 1806 will drive the rotating hook 1807 toward the top, the movement of the rotating hook 1807 will contact the fixed hook 1804, the fixed hook 1804 will push the rotating hook 1807 to move in the direction of the hydraulic rod 9, and the movement of the rotating hook 1807 will drive the vertical plate 1806 toward the hydraulic rod 9.

When moving in the direction away from the fixed block 1704, when the elasticity of the torsion spring is not released, the support block 1705 cannot move to the bottom, preventing the sliding block 1701 from being able to successfully reset through the V-shaped spring piece 1707 when the sliding block 1701 moves in the direction away from the fixed block 1704 due to the excessive resistance between the support block 1705 and the sliding block 1701, thereby ensuring the continuity of the device during operation; when the fixed hook 1804 rotates the hook 1807 to move in the direction of the hydraulic rod 9, the movement of the rotating hook 1807 will drive the limit block 1811 to rotate toward the bottom, and the limit block 1811 is blocked by the arc rod 1810 and the cylinder 1809, making it impossible for the limit block 1811 to move to the bottom, so that after the fixed hook 1804 contacts the rotating hook 1807, the fixed hook 1804 will only push the rotating hook 1807 to move in the direction of the hydraulic rod 9, and will not be limited when the rotating hook 1807 rotates to the top, thereby improving the practicability of the device.
