Description

Technical Field

[0001] The utility model relates to the technical field of transformer equipment, and more specifically to a dry-type transformer with a built-in stable structure. Background Art

[0002] The temperature change inside the existing transformer will cause the windings and the iron core to expand and contract thermally. Without effective structural support, it may cause friction or displacement between these components, leading to failures. Summary of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a dry-type transformer with a built-in stable structure to solve the problem that the temperature change inside the existing transformer will cause the windings and the iron core to expand and contract thermally. Without effective structural support, it may cause friction or displacement between these components, leading to failures, as described in the above background art.

[0004] The utility model provides the following technical solutions: including an inner lining shell, two clamping plate support frames are fixedly installed at the bottom end and the top end inside the inner lining shell. The number of the clamping plate support frames is four. Elastic gaskets are fixedly installed on the clamping plate support frames. A winding iron core is fixedly clamped between the elastic gaskets. The clamping plate support frames and the inner lining shell are fixedly connected by multiple threaded rods. The main body material of the clamping plate support frames is insulating polyester fiberglass board, and the main body material of the elastic gaskets is fluororubber. When in use, this structure will provide mechanical stability for the entire transformer. Through the connection of high-strength clamping plate support frames and threaded rods, it is ensured that the winding iron core will not shift under mechanical vibration and impact. At the same time, the elastic gaskets provide a certain elastic space, allowing slight movement during thermal expansion to avoid mechanical stress concentration. Through this design, the mechanical structure stability and reliability of the transformer are significantly improved, effectively preventing damage to the windings caused by mechanical stress, extending the service life of the transformer. The clamping plate support frames and the elastic gaskets work together to absorb external vibrations and protect the structural integrity of the winding iron core. It effectively solves the problem that the temperature change inside the existing transformer will cause the windings and the iron core to expand and contract thermally. Without effective structural support, it may cause friction or displacement between these components, leading to failures.

[0005] Further, a circle of inner lining support frames is fixedly installed on the outer surface of the inner lining shell, and a circle of outer shells is fixedly installed on the outer surface of the inner lining support frames. When in use, the inner lining shell and the outer shells use the inner lining support frames as a support structure, which can further enhance the structural strength of the outer surface of the entire device.

[0006] Furthermore, heat dissipation air ducts are fixedly installed on both sides of the inner lining shell. Both sides of the heat dissipation air ducts extend to the outside of the outer shell, and heat dissipation fans are arranged inside the heat dissipation air ducts. During use, the heat dissipation fans inside the heat dissipation air ducts can quickly extract the hot air inside the inner lining shell to the outside, preventing serious thermal expansion due to excessive temperature inside the inner lining shell.

[0007] Furthermore, four damping shock absorbers are fixedly installed at the bottom end of the outer shell, and a device bottom plate is simultaneously installed at the bottom ends of the damping shock absorbers. During use, the damping shock absorbers can effectively reduce the vibration generated by the device, and the damping shock absorbers can provide shock absorption and buffering for the device.

[0008] Furthermore, an arched anti-collision plate is fixedly installed at the top end of the outer shell. A plurality of support rods are fixedly installed at the bottom end of the arched anti-collision plate, and the main body material of the arched anti-collision plate is stainless steel. During use, when the top end of the arched anti-collision plate is subjected to a huge impact from a falling heavy object, the structure of the arched anti-collision plate can effectively provide buffering for the heavy object.

[0009] Furthermore, the main body materials of the inner lining shell, the inner lining support frame, and the outer shell are all stainless steel metals with an aluminum oxide film plated on the outer surface.

[0010] Technical effects and advantages of the present utility model:

[0011] 1. By providing an inner lining shell, a clamping plate support frame, an elastic gasket, and a winding iron core, the present utility model effectively solves the problem that the temperature change inside the existing transformer can cause the winding and the iron core to thermally expand and contract, and the lack of effective structural support may cause friction or displacement between these components, resulting in faults.

[0012] 2. By providing an inner lining support frame and an outer shell, during use, the inner lining shell and the outer shell use the inner lining support frame as a support structure, which can further enhance the structural strength of the outer surface of the entire device.

[0023] Working principle: During use, this structure provides mechanical stability for the entire transformer. It is connected by high-strength clamping plate support frames 110 and threaded rods to ensure that the winding core 112 does not shift under mechanical vibration and impact. At the same time, the elastic gasket 111 provides a certain elastic space, allowing for slight movement during thermal expansion to avoid mechanical stress concentration. Through this design, the mechanical structure stability and reliability of the transformer are significantly improved, effectively preventing damage to the windings caused by mechanical stress and extending the service life of the transformer. The clamping plate support frames 110 and the elastic gasket 111 work together to absorb external vibrations and protect the structural integrity of the winding core 112.
