Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a shockproof function. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. It can realize voltage conversion, current conversion, impedance conversion and other operations. It is often used in places that require large amounts of power supply, such as airports, hospitals or shopping malls. It is also set up in the wild to cooperate with wind power and solar power generation.

[0003] The main components of a transformer are two coils, one called the "high-voltage coil" and the other called the "low-voltage coil". When current passes through the high-voltage coil, the electromagnetic force causes the interaction between the coil and the iron core to produce vibrations. Especially under high current loads, the electromagnetic force will be more significant, and the transformer vibration will intensify. At the same time, the uneven magnetic field will also cause the force imbalance between the coil and the iron core to produce vibrations. Existing transformer components are often installed on the bracket by bolts. Long-term vibration will cause metal fatigue of the bolts, greatly reducing the installation stability of the transformer and affecting the safety of electricity use. In response to the above problems, we proposed a transformer with shockproof function. Utility Model Content

[0004] In view of the shortcomings of the existing transformers having poor shock absorption effect and affecting the safety of electricity use, the utility model provides a transformer with shockproof function, which has the advantages of good shock absorption effect and ensuring the safety of electricity use, and solves the problems raised in the above background technology.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A transformer with an anti-vibration function is designed, comprising a protective box, wherein the top and bottom of the inner cavity of the protective box are both provided with mounting crossbeams, an iron core is installed between the mounting crossbeams, a coil is installed on the outer side of the iron core column, a sealing top cover is provided above the coil, a connecting column head corresponding to the coil is installed on the top of the sealing top cover, and the bottom end of the connecting column head is connected to the coil through a wire;

[0007] Shock-absorbing mechanisms are provided at both ends of the mounting crossbeam, and the mounting crossbeam is connected to the protective box through the shock-absorbing mechanism. The shock-absorbing mechanism includes an L-shaped plate, and a plurality of first rubber pads are symmetrically provided at the top and the bottom of one side of the L-shaped plate, and a strip seat is provided on the top of the first rubber pad located at the top, and one side of the strip seat is connected to the protective box, and stud bolts are provided between the first rubber pads, and the stud bolts respectively penetrate the strip seat and the outside of the first rubber pad and are coaxially spirally connected with nuts;

[0008] The other side of the L-shaped plate is fixedly connected to a limiting block, the limiting block is located inside the mounting crossbeam, and the limiting block is connected to the mounting crossbeam via bolts.

[0009] Optionally, two bases are symmetrically installed at the bottom of the inner cavity of the protection box, and a second rubber pad is fixedly installed on the top of each base, and the top of the second rubber pad is in contact with the installation beam.

[0010] Optionally, heat dissipation fins are provided discontinuously and evenly spaced on the outer side of the protection box body, the heat dissipation fins are perpendicular to the protection box body, and one side of the heat dissipation fins is connected to the protection box body.

[0011] Optionally, connecting parts are provided at the bottom edges on both sides of the sealing top cover and at the top edges on both sides of the protective box body, and the connecting parts are connected by bolts.

[0012] Optionally, a plurality of mounting seats are symmetrically mounted on the bottom of the protective box, and the mounting seats are U-shaped in design.

[0013] Optionally, a plurality of insulators are provided on the outer side of the top end of the connecting stud, and the plurality of insulators are equidistantly distributed along the axial direction of the connecting stud, and the insulators are fixedly mounted on the connecting stud.

[0014] Compared with the prior art, during use, the utility model installs the transformer assembly firmly inside the protective box by means of the shock-absorbing mechanisms at both ends of the cross beam. When the protective box vibrates, the first rubber pads at the top and bottom of one side of the multiple L-shaped plates will eliminate the vibration, thereby preventing the transformer assembly from being affected by the vibration force. At the same time, it also avoids the problem of the transformer assembly being fastened inside the shell by bolts, resulting in the connection feet being in a rigid connection, which may cause metal fatigue after long-term use.

[0025] The other side of the L-shaped plate 9 is fixedly connected to a limit block 10, which is located inside the mounting beam 4. The limit block 10 is connected to the mounting beam 4 by bolts.
