DETAILED DESCRIPTION

[0026] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The noise reduction dry-type transformer according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 7 As shown, the noise reduction dry-type transformer according to the embodiment of the present invention may include a transformer body 100 , a connecting frame 200 , a first connecting structure 300 , a mounting frame 400 and a damping connecting member 500 .

[0029] The two connection frames 200 are respectively arranged at the upper and lower ends of the transformer body 100 through the first connection structure 300 .

[0030] like Figure 6 As shown, each first connection structure 300 includes a rubber block 310 , a connection plate 320 and a stud 330 .

[0031] The two studs 330 are integrally formed with the two connecting plates 320 , and the two connecting plates 320 are fixedly arranged at the upper and lower ends of the rubber block 310 , respectively. The two studs 330 are respectively threadedly connected to the transformer body 100 and the corresponding connecting frame 200 and locked.

[0032] As a possible scenario, the connecting plate 320 and the rubber block 310 are connected by insert molding.

[0033] It should be noted that when the transformer body 100 vibrates, the vibration can be transmitted to the rubber block 310 by the stud 330 and the connecting plate 320 , thereby reducing the upward or downward vibration transmission of the transformer body 100 and reducing noise.

[0034] The mounting bracket 400 is disposed below the bottom connecting bracket 200 and is connected to the connecting bracket 200 via a damping connector 500 .

[0035] like Figure 2 As shown, the damping connection 500 includes a damping rod 510 and a spring 520 .

[0036] The damping rod 510 is connected to the mounting frame 400 and the bottom connecting frame 200 . The spring 520 is sleeved on the damping rod 510 , and its two ends are respectively connected to the mounting frame 400 and the bottom connecting frame 200 .

[0037] As a possible scenario, a limit pin is provided on the damping rod 510 to limit the maximum telescopic range of the damping rod 510 to prevent excessive deformation.

[0038] It should be noted that when the connecting frame 200 at the bottom vibrates, the damping rod 510 will be slightly displaced. Due to the damping effect of the damping rod 510, part of the vibration energy will be consumed during the vibration transmission process, thereby reducing the vibration amplitude. In addition, combined with the part of the vibration energy absorbed by the deformation of the spring 520 itself, the vibration transmitted to the mounting frame 400 is further reduced.

[0039] Specifically, when the transformer body 100 vibrates, the upper and lower first connection structures 300 respectively reduce the vibration amplitude of the transformer body 100 transmitting vibration to the upper and lower ends through the elastic properties of the rubber blocks 310 .

[0040] The damping connector 500 at the bottom can further reduce the downward propagation of vibration of the transformer body 100 , thereby further reducing the noise generated by the vibration.

[0041] By cooperating with the first connection structure 300 at the bottom and the damping connection member 500, a multi-stage vibration isolation effect is formed, which can reduce the generation and transmission of vibration and noise; through the first connection structure 300 at the top, vibration isolation can be performed from above the transformer body 100, thereby reducing the generation and transmission of vibration and noise in multiple directions.

[0042] In one embodiment of the present invention, Figures 3 to 5 As shown, the connecting frame 200 includes a C-shaped steel 210 and a second connecting structure 220 , wherein the two C-shaped steels 210 are arranged opposite to each other, and both ends are connected by the second connecting structure 220 .

[0043] To clearly illustrate the previous embodiment, in one embodiment of the present invention, the second connection structure 220 includes a screw rod 221 , a rubber sleeve 222 , a rubber connector 223 and a nut 224 .

[0044] Among them, the two ends of the screw 221 pass through the two C-shaped steels 210 respectively and extend outward. The rubber sleeve 222 is sleeved on the screw 221, and the two ends of the rubber sleeve 222 are respectively in contact with the opposite surfaces of the two C-shaped steels 210. The two rubber connectors 223 are respectively arranged on the two extending ends of the screw 221 and are respectively locked by nuts 224.

[0045] It should be noted that through holes 211 are opened on the opposite surfaces of the two C-shaped steels 210, and the screw rods 221 pass through the two through holes 211 in sequence.

[0046] As a possible scenario, the rubber connector 223 includes a rubber pad 2231 and a gasket 2232 , wherein the gasket 2232 is fixed to the side of the rubber pad 2231 away from the C-shaped steel 210 , and the end of the screw rod 221 passes through the rubber pad 2231 and the gasket 2232 in sequence.

[0047] Specifically, when connecting two C-shaped steels 210, first insert the screw 221 through the through hole 211 of the C-shaped steel 210 on one side. Before inserting it into the through hole 211 of the other C-shaped steel 210, put the rubber sleeve 222 on the screw 221, and then pass the screw 221 out of the through hole 211 of the other C-shaped steel 210.

[0048] Next, the relevant staff will respectively put the rubber connector 223 on both ends of the screw 221, and then lock it with the nut 224 so that the nut 224 abuts against the gasket 2232. At this time, the rubber connector 223 is squeezed, the rubber pad 2231 is slightly deformed, and abuts against the C-shaped steel 210, and the rubber sleeve 222 is located between the two C-shaped steels 210, is squeezed and deformed, and abuts between the two C-shaped steels 210.

[0049] In one embodiment of the present invention, the rubber block 310 is prism-shaped or cylindrical-shaped to better achieve the vibration reduction function.

[0050] Among them, when the rubber block 310 is a prismatic structure, it has better stability, especially better stability in the vertical direction. When the rubber block 310 is a cylindrical structure, it has a certain self-alignment ability and can adapt to the slight offset of the connecting plate 320. The cylindrical rubber block 310 can better achieve uniform stress distribution.

[0051] Therefore, in practical applications, a suitable shape of the rubber block 310 can be selected according to specific needs.

[0052] In summary, according to the noise reduction dry-type transformer of the embodiment of the present invention, multi-level vibration isolation is achieved through the arrangement of the first connection structure 300 and the damping connection member 500 at the bottom, thereby improving the overall vibration isolation efficiency and reducing the generation of noise; in addition, the first connection structure 300 at the top can effectively cut off or weaken the vibration path transmitted from the transformer body 100 to the top structure, further reducing the propagation of vibration.
