Description

Technical Field

[0001] The present application relates to the field of transformers, and in particular to an energy-saving, environmentally friendly and low-noise dry-type transformer. Background Art

[0002] A dry-type transformer is a device that uses the principle of electromagnetic induction to change AC voltage, with the core and winding not immersed in insulating oil.

[0003] In the prior art, a dry-type transformer generally includes a base, an iron core, a clamping mechanism, a coil and an insulating cylinder. The iron core is fixed to the base through the clamping mechanism, the coil is wound on the iron core, and the insulating cylinder is sleeved outside the coil to increase electrical insulation.

[0004] When the transformer is working, low-frequency noise is easily generated between the iron core and the base due to vibration. When exposed to low-frequency noise for a long time, the human body is easily injured, and there is still room for improvement. Utility Model Content

[0005] In order to improve the stability of transformer use and reduce the operating noise of the transformer, the present application provides an energy-saving, environmentally friendly and low-noise dry-type transformer.

[0006] An energy-saving, environmentally friendly and low-noise dry-type transformer comprises a base and an iron core arranged on the base, a vibration damping plate is arranged on a side of the iron core close to the base, a buffer is arranged between the vibration damping plate and the base, a mounting groove for installing the buffer is provided on the base, and a mounting cavity for installing the buffer is provided on the vibration damping plate.

[0007] By adopting the above technical solution, when the transformer is working, the iron core is likely to vibrate on the base and generate noise. When the iron core vibrates, the vibration of the iron core on the base is reduced by the buffer, thereby reducing the working noise of the transformer and further improving the stability of the transformer.

[0008] Preferably, a side of the vibration damping plate close to the base is provided with a rib, the rib is symmetrically arranged in the length direction of the vibration damping plate, and a baffle that contacts the rib is arranged on the base.

[0009] By adopting the above technical solution, the retaining edge and the baffle are pressed against each other, thereby improving the stability of the vibration of the vibration damping plate on the base when the iron core vibrates, reducing the situation where the vibration damping plate is separated from the base, and thus improving the stability of the vibration damping plate installation.

[0010] Preferably, a limiting column is provided on one side of the base close to the vibration damping plate, the limiting column is located between the baffles, and a sliding cavity for the limiting column to be inserted and slide is opened on the vibration damping plate.

[0011] By adopting the above technical solution, the limiting column presses against the vibration damping plate in the sliding cavity, thereby improving the stability of the vibration of the vibration damping plate on the base when the iron core vibrates, reducing the situation where the vibration damping plate is separated from the base, and further improving the stability of the vibration damping plate installation.

[0012] Preferably, a buffer layer is provided on one side of the vibration damping plate close to the iron core, and the buffer layer is in close contact with the iron core.

[0013] By adopting the above technical solution, the buffer layer is made of a material with good elasticity such as rubber, thereby reducing the noise caused by the vibration of the iron core on the vibration damping plate, thereby improving the stability of the vibration damping plate.

[0014] Preferably, the vibration damping plate is provided with an embedding groove for installing the iron core, and the buffer layer is located in the embedding groove.

[0015] By adopting the above technical solution, the iron core is pressed against the vibration damping plate in the embedded groove, thereby reducing the situation where the iron core is offset or even separated from the vibration damping plate due to excessive amplitude of the iron core, thereby improving the stability of the use of the iron core.

[0016] Preferably, a clamping plate for limiting the sliding direction of the iron core is symmetrically arranged on one side of the base close to the iron core, and two sides of the vibration-damping plate are in contact with the clamping plate.

[0017] By adopting the above technical solution, the two sides of the iron core are clamped by the clamping plate, so that the iron core is fixed on the base, and the two sides of the vibration damping plate are in contact with the clamping plate, thereby reducing the deviation of the vibration damping plate on the base, thereby improving the stability of the vibration damping plate.

[0018] Preferably, limit blocks are symmetrically arranged on both sides of the vibration damping plate, and slots for the limit blocks to slide are opened on the clamping plate.

[0019] By adopting the above technical solution, the limit block is pressed against the clamping plate in the slot, thereby reducing the sliding of the vibration damping plate on the clamping plate along the length direction of the clamping plate, thereby improving the stability of the vibration damping plate installation.

[0020] Preferably, a reinforcing rib is provided between the clamping plate and the base, and the reinforcing rib is located on a side of the clamping plate away from the vibration damping plate.

[0021] By adopting the above technical solution, the side of the reinforcing rib close to the clamping plate is integrally arranged with the clamping plate, and the side of the reinforcing rib close to the base is integrally arranged with the base, thereby strengthening the connection between the clamping plate and the base, reducing deformation of the clamping plate, and further improving the stability of the clamping plate.

[0022] Preferably, foot supports are symmetrically arranged on one side of the base away from the vibration damping plate.

[0023] By adopting the above technical solution, the base is kept away from the ground through the foot support, thereby reducing the leakage of the transformer caused by moisture and reducing the damage to the transformer, thereby improving the stability of the transformer.

[0024] Preferably, a buffer pad is provided on a side of the foot support away from the base.

[0025] By adopting the above technical solution, the buffer pad is made of a material with good elasticity such as rubber. The buffer pad reduces the noise between the foot support and the ground when the transformer vibrates, thereby improving the stability of the foot support.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When the core vibrates, the vibration of the core on the base is reduced by the buffer, thereby reducing the working noise of the transformer and improving the stability of the transformer;

[0028] 2. The limit column presses against the vibration damping plate in the sliding cavity, thereby improving the stability of the vibration of the vibration damping plate on the base when the iron core vibrates, reducing the situation where the vibration damping plate is separated from the base, and thus improving the stability of the vibration damping plate installation;

[0029] 3. The cushion pad can reduce the noise between the foot support and the ground when the transformer vibrates, thereby improving the stability of the foot support. BRIEF DESCRIPTION OF THE DRAWINGS

The iron core 2 is arranged on the base 1, and the coil 20 is wound on a column arranged along the height direction of the iron core 2. The insulating cylinder 22 is sleeved outside the coil 20 to improve the electrical insulation of the coil 20 from the outside. The vibration damping plate 3 is located between the iron core 2 and the base 1. The vibration damping plate 3 is provided with an embedding groove 12 for the iron core 2 to be placed on the side close to the iron core 2. The iron core 2 is pressed against the vibration damping plate 3 in the embedding groove 12 to reduce the slippage of the iron core 2 on the vibration damping plate 3. The buffer 4 is arranged between the vibration damping plate 3 and the base 1. The buffer 4 is used to reduce the vibration between the buffer layer 11 and the base 1, thereby reducing the noise of the transformer. In this embodiment, three buffers 4 are evenly arranged along the length direction of the vibration damping plate 3. The foot support 17 is symmetrically arranged on the side of the base 1 away from the iron core 2. A buffer pad 18 is fixed to the side of the foot support 17 away from the base 1 through acrylic structural adhesive. The buffer pad 18 is used to reduce the vibration between the transformer and the ground to reduce the noise of the transformer.

[0036] Reference Figure 1 and Figure 2 The transformer also includes a fixing plate 19, a clamping plate 13 and a fan 21. The fixing plate 19 is fixed to the side of the insulating tube 22 away from the base 1 by bolts, and the fixing plate 19 cooperates to clamp the end of the fixed iron core 2 away from the base 1. The clamping plate 13 is integrally arranged on the side of the base 1 close to the iron core 2, and the clamping plate 13 cooperates to clamp the fixed iron core 2 close to the base 1. Both sides of the vibration damping plate 3 are pressed against the clamping plate 13. The fixing plate 19 and the clamping plate 13 cooperate to fix the iron core 2 on the base 1. A reinforcing rib 16 for improving the structural strength of the clamping plate 13 is provided between the clamping plate 13 and the base 1, and the reinforcing rib 16 is located on the side of the clamping plate 13 away from the iron core 2. The fan 21 is arranged on the side of the base 1 close to the iron core 2, and the fan 21 is used to increase the heat dissipation speed of the transformer.

[0037] Reference Figure 1 and Figure 2 The vibration damping plate 3 is provided with an installation cavity 6 for installing the buffer 4, and the base 1 is provided with an installation groove 5 for installing the buffer. One end of the buffer 4 is pressed against the vibration damping plate 3 in the installation cavity 6, and the other end of the buffer 4 is pressed against the base 1 in the installation groove 5, so that the buffer 4 is fixed between the vibration damping plate 3 and the base 1. The buffer 4 is a buffer material, and a spring damper is taken as an example in this embodiment.

[0038] Reference Figure 2 and Figure 3, a side of the vibration damping plate 3 close to the base 1 is symmetrically provided with a rib 7 along the length direction, and a baffle 8 for pressing the limiting rib 7 is symmetrically provided on the side of the base 1 close to the vibration damping plate 3, and the side of the baffle 8 close to the iron core 2 presses against the rib 7. A limiting column 9 is integrally provided on the side of the base 1 close to the vibration damping plate 3, and the limiting column 9 is located between the two baffles 8. A sliding cavity 10 for the limiting column 9 to be inserted and slide is provided on the side of the vibration damping plate 3 close to the base 1. The limiting column 9 presses against the vibration damping plate 3 in the sliding cavity 10, thereby reducing the vibration damping plate 3 from sliding on the base 1. In this embodiment, two limiting columns 9 are evenly provided along the length direction of the vibration damping plate 3, and the limiting columns 9 are spaced apart from the buffer 4.

[0039] Reference Figure 3 , the vibration damping plate 3 is symmetrically provided with limit blocks 14 on both sides close to the clamping plate 13, and the clamping plate 13 is provided with a slot 15 for the limit blocks 14 to be inserted and slid. The limit blocks 14 are pressed against the clamping plate 13 in the slot 15, thereby reducing the vibration damping plate 3 from being separated from the base 1. In this embodiment, two groups of limit blocks 14 are symmetrically provided in the length direction of the vibration damping plate 3.

[0040] Working principle:

[0041] When the transformer is working, the iron core 2 vibrates, and the vibration of the iron core 2 is transmitted to the vibration damping plate 3 through the buffer layer 11, thereby causing the vibration damping plate 3 to vibrate. A part of the vibration transmitted to the vibration damping plate 3 is buffered by the buffer layer 11, and the buffer member 4 always presses the vibration damping plate 3. When the vibration damping plate 3 vibrates, the buffer member 4 absorbs the vibration and is deformed, thereby reducing the vibration transmitted from the vibration damping plate 3 to the base 1, thereby reducing the noise when the transformer is working.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
