[0002] A lot of noise will be generated during the transformer transformation process. The noise not only affects the living environment of the surrounding residents, but also generates a certain vibration frequency during the noise generation process, thereby causing resonance of the transformer and having adverse consequences for the safe operation of the transformer. However, shock absorption not only needs to meet the energy consumption capacity, but also requires the shock absorber itself to have a relatively low cost, a relatively simple structure and connection, and a strong shock absorption and energy consumption capacity.

[0003] In the prior art, the shock absorbing device used for the transformer usually adopts springs for shock absorption. However, the structure of the shock absorbing device in the prior art is unreasonable. Although the transformer can be supported and shock-absorbed, the freedom of the transformer in the horizontal direction cannot be effectively limited, resulting in poor stability of the shock absorbing device.

[0004] Therefore, the transformer damper in the prior art has the technical problem of poor stability. Summary of the invention

[0037] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0038] Reference Figures 1 to 6 As shown, a transformer shock absorber with strong stability comprises a base 1, wherein the base 1 is provided with a mounting plate 2 for mounting the transformer, and the mounting plate 2 is mounted on the base 1 via an elastic connector 3 which limits the degree of freedom of the mounting plate 2 in the vertical direction;

[0039] The base 1 is further provided with a positioning frame 11, and an elastic member 12 is provided between the positioning frame 11 and the mounting plate 2 to limit the horizontal freedom of the mounting plate 2, and the elastic member 12 is installed on the positioning frame 11;

[0040] The elastic connector 3 includes an upper frame 31 mounted on the mounting plate 2 and a lower frame 32 mounted on the base 1, the height of the upper end of the lower frame 32 is higher than the height of the lower end of the upper frame 31, and a steel wire rope 33 is provided between the lower end of the upper frame 31 and the upper end of the lower frame 32;

[0041] A vertical spring 34 is disposed at the upper end of the lower frame 32 , and a mounting column 35 for mounting the vertical spring 34 is disposed at the upper end of the lower frame 32 and the mounting plate 2 . The vertical spring 34 is sleeved on the mounting column 35 .

[0042] The upper frame 31 and the lower frame 32 are connected by a steel wire rope 33. The upper frame 31 is fixed to the mounting plate 2, and the lower frame 32 is fixed to the base 1. The upper frame 31 is hung on the lower frame 32 by the steel wire rope 33, that is, the mounting plate 2 is hung on the lower frame 32 by the steel wire rope 33. Since the steel wire rope 33 has a certain flexibility, the upper frame 31 is flexibly connected to the lower frame 32, that is, the vibration generated by the upper frame 31 is not easily transmitted to the lower frame 32 through the steel wire rope 33, or the vibration generated by the lower frame 32 is not easily transmitted to the upper frame 31 through the steel wire rope 33.

[0043] However, the upper frame 31 is suspended on the lower frame 32, and the upper frame 31 and the mounting plate 2 are limited in the vertical direction, and the horizontal freedom is limited by the positioning frame 11 and the elastic member 12, and the elastic member 12 can be a spring. The spring limits the horizontal freedom of the mounting plate 2, and cooperates with the elastic connector 3, so that the vertical and horizontal freedom of the mounting plate 2 are limited, thereby improving the stability of the transformer shock absorber.

[0044] The vertical spring 34 and the mounting column 35 are used to assist in positioning the freedom of the mounting plate 2 in the horizontal direction.

[0045] Reference Figures 1 to 6 As shown, in some embodiments, a support spring 13 is provided between the base 1 and the mounting plate 2 , the upper end of the support spring 13 is fixed to the mounting plate 2 , and the lower end of the support spring 13 is fixed to the base 1 .

[0046] There are multiple support springs 13 , and the multiple support springs 13 are evenly distributed between the base 1 and the mounting plate 2 .

[0047] The upper end of the support spring 13 is fixed to the mounting plate 2 by bolts, and the lower end of the support spring 13 is fixed to the base 1 by screws. The support spring 13 is used to assist in positioning the horizontal degree of freedom of the mounting plate 2. Moreover, after the steel wire rope 33 fails, the support spring 13 plays the function of supporting the mounting plate 2, and the transformer shock absorber has better stability.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the upper frame 31 includes an upper end plate 311, and an upper connecting rib 312 is arranged between the upper end plate 311 and the mounting plate 2, the upper end plate 311 and the upper connecting rib 312 are an integral structure, and the upper connecting rib 312 is welded to the mounting plate 2.

[0049] The lower frame 32 includes a lower end plate 321, and a lower connecting rib 322 is arranged between the lower end plate 321 and the base 1. The lower connecting rib 322 and the lower end plate 321 are an integral structure. The lower connecting rib 322 is welded to the base 1, and the upper connecting rib 312 and the lower connecting rib 322 are staggered.

[0050] The mounting post 35 mounted on the lower frame 32 and the lower end plate 321 are an integrated structure.

[0051] The upper frame 31 , the lower frame 32 , and the steel wire rope 33 are coaxially arranged, and the mounting column 35 and the steel wire rope 33 are coaxially arranged.

[0052] The transformer can be fixed to the mounting plate 2 by screws. The mounting plate 2 applies a vertical downward force to the wire rope 33 under the action of its own weight and the weight of the transformer. Since the upper frame 31, the lower frame 32, and the wire rope 33 are coaxially arranged, and the mounting column 35 is coaxially arranged with the wire rope 33, the force borne by the wire rope 33 is a vertical downward force. Therefore, when the mounting plate 2 is offset from the base 1, it needs to overcome the gravity of the mounting plate 2 and the gravity of the transformer to move obliquely upward. Therefore, the mounting plate 2 is not easy to be misplaced relative to the base 1, that is, the mounting plate 2 is not easy to shake in the horizontal direction.

[0053] Reference Figures 1 to 6 As shown, in some embodiments, the positioning frame 11 is fixed to the base 1 via a connecting plate 111 , the positioning frame 11 and the connecting plate 111 are an integrated structure, and the connecting plate 111 is fixed to the base 1 via screws.

[0054] The positioning frame 11 includes a frame body 112 and a support rod 113 . The support rod 113 is located between the frame body 112 and the connecting plate 111 . The elastic member 12 is installed on the frame body 112 .

[0055] The frame 112 , the support rod 113 , and the connecting plate 111 are an integrated structure. The elastic member 12 is a spring. The elastic member 12 is evenly distributed between the frame 112 and the mounting plate 2 .

[0056] The elastic member 12 may be welded to the frame 112 , or the elastic member 12 may be fixed to the frame 112 via a detachable connection.

[0057] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.

[0058] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.

[0059] When implementing the subject technical solution of the utility model, those skilled in the art can obtain other detailed configurations or drawings according to the subject technical solution of the utility model and the drawings. Obviously, these details still fall within the scope covered by the subject technical solution of the utility model without departing from the subject technical solution of the utility model.
