Description

Technical Field

[0001] The utility model relates to the technical field related to power transformers, in particular to a seismic-resistant and stable power transformer. Background Art

[0002] In the power system, in order to ensure the stable transmission and regulation of electricity, various power equipment will be used. The power transformer is a static electrical equipment that is used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency. The power transformer is one of the main equipment in power plants and substations.

[0003] The prior art has the following deficiencies: the prior art publication number CN215299008U states that “an earthquake-resistant power transformer” “includes a power pole, a placement platform, a transformer body, and a side stabilizing frame; the placement platform is fixedly arranged between two power poles, and the transformer body is fixedly arranged on the placement platform; the side stabilizing frame is symmetrically fixedly arranged on the top of the transformer body, the placement platform includes a first clamp and two horizontal steel bars, the steel bar is arranged in three sections, two of which are respectively fixedly arranged on the first clamp, one end of the middle section steel bar is transferred to the fixed steel bar on one side through a rotating shaft, and the other side of the middle section steel bar is transferred and overlapped with the fixed steel bar on the other side, and a first shock absorber is arranged in the overlap contact, one end of the transformer body is fixedly arranged on the middle section steel bar at one end of the first shock absorber through an I-beam, and the other bottom is fixed to the other end of the middle section steel bar through a second shock absorber”;

[0004] However, the power transformer as a whole has a certain weight, and the clamp is fixed on the outside of the pole. When vibration occurs, the transformer body will vibrate accordingly, which will cause wear between the clamp and the pole. Long-term vibration will cause damage to the clamp, and then cause the transformer body to fall. Moreover, relying solely on two sets of shock absorbers to weaken the generated vibration has a poor overall shock absorption effect, which is not conducive to the stable use of the transformer.

[0006] To achieve the above object, the utility model provides the following technical solutions: a seismically stable power transformer, comprising a transformer body, two sets of mounting frames, a shock absorbing assembly and a mounting assembly, wherein the two sets of mounting frames are symmetrically welded and mounted on the top of the transformer body, the shock absorbing assembly is mounted on the bottom of the transformer body, and the mounting assembly is mounted below the transformer body and located on both sides of the shock absorbing assembly;

The multiple groups of first shock absorption dampers are symmetrically installed at the bottom of the fixed plate. The protective cover is installed at the bottom of the first shock absorption damper through bolts. The buffer part is installed inside the protective cover.

[0008] As a further preference of this technical solution, the buffer part includes two groups of limit openings, multiple groups of fixed frames, two groups of sliding openings, sliding blocks, shock absorption springs, and two groups of second shock absorption dampers. The two groups of limit openings are symmetrically opened on the top surface of the protective cover. The multiple groups of fixed frames are symmetrically installed at the inner bottom of the protective cover through bolts. The two groups of sliding openings are symmetrically opened on the surface of the fixed frames. The sliding blocks are installed inside the fixed frames. The shock absorption springs are installed between the sliding blocks and the fixed frames. The two groups of second shock absorption dampers are installed between the pressing blocks and the inner bottom of the protective cover through bolts.

[0009] As a further preference of this technical solution, the clamping strips are correspondingly arranged with the mounting frame, the pressing blocks are correspondingly arranged with the limit openings, and the pressing blocks extend from the limit openings into the protective cover.

[0014] The utility model provides an earthquake-resistant and stable power transformer, which has the following beneficial effects:

[0015] (1) By providing the mounting assembly in the utility model, the fixing rings can be stabilized by using the extension rods. With the arrangement of the two groups of fixing rings, the installation limit between the protective cover and the telegraph pole can be carried out, and the two groups of fixing rings can be connected and fixed by using the fixing bolts, so as to complete the installation and fixation of the transformer body.

[0016] (2) The utility model is provided with a shock-absorbing assembly, and the clamping strip and the mounting frame can be connected and installed by using a long-axis bolt. When vibration occurs, the transformer body is pressed down, causing the fixed plate to be pressed down.
