Description

Technical Field

[0001] The invention relates to the technical field of oil-immersed transformers, in particular to a low-noise, 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 relates to 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 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 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 work together to greatly improve the heat dissipation effect while ensuring 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 solution, a No. 1 spring is provided between the sliding vertical rod and the triangular frame, the insulating seat contacts the fixed end of the elastic telescopic rod, and the sliding vertical rod is reset by the No. 1 spring.

[0009] According to the above technical solution, the supporting device includes: a sliding block, a triangular pad, a load-bearing block, a fixed block, a supporting block, a baffle 1, a V-shaped spring piece and a baffle 2.

[0015] The present invention provides a low-noise, environmentally friendly oil-immersed transformer with the following beneficial effects:

[0016] (1) This invention drives the insulating seat to move toward the top after the free end of the elastic telescopic rod moves toward the bottom 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 amplitude of the transformer body's own shaking 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 degree of vibration 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 make noise, thereby reducing decibels and noise pollution.

[0017] (2) In this 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.

[0018] (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, the support block cannot move to the bottom, preventing the sliding block from being unable to 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.
