DETAILED DESCRIPTION

[0026] The following describes embodiments of the present invention in detail, 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 be used to explain the present invention, and are not to be construed as limiting the present invention.

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

[0028] like Figure 1-Figure 5 As shown, a dry-type transformer with stable installation according to an embodiment of the present invention includes: a dry-type transformer 1 and a buffer mechanism 2.

[0029] The buffer mechanism 2 includes a housing 21 , a connecting rod 23 , an isolation column 24 , a limiting column 25 , a first spring 26 and a connecting plate 27 .

[0030] Among them, the shell 21 is arranged at the bottom of the dry-type transformer 1, and the inner walls of the shell 21 are respectively provided with connecting grooves 22, and the connecting rods 23 are respectively arranged inside the corresponding connecting grooves 22. The isolation columns 24 are respectively arranged at one end of the corresponding connecting rods 23, and the two ends of the isolation columns 24 are respectively connected to the connecting rods 23, and the limiting columns 25 are respectively arranged on the outside of the corresponding connecting grooves 22. The first springs 26 are respectively sleeved on the outside of the corresponding limiting columns 25, and one end of the first spring 26 is connected to the inner wall of the shell 21, and the connecting plate 27 is connected to the other end of the first spring 26.

[0031] A connecting assembly 28 is provided on the outside of the connecting rod 23 .

[0032] The connecting assembly 28 includes a push block 281 , a connecting column 282 and a fixing block 283 .

[0033] Among them, the push blocks 281 are respectively arranged on the outside of the corresponding connecting rods 23, the connecting columns 282 are respectively pivotally connected to the corresponding push blocks 281, the fixed blocks 283 are pivotally connected to the other ends of the connecting columns 282, and the fixed blocks 283 are connected to the bottom wall of the connecting plate 27.

[0034] A second spring 284 is sleeved on the outer wall of the connecting rod 23 , and one end of the second spring 284 is connected to the isolation column 24 , and the other end of the second spring 284 is connected to the push block 281 .

[0035] A heat dissipation assembly 29 is provided on the outer shell 21, wherein the heat dissipation assembly 29 includes a heat dissipation fan 293 and a protective net 294. The outer wall of the outer shell 21 is provided with heat dissipation holes 291, and the inner walls of the heat dissipation holes 291 are respectively provided with installation grooves 292, and the heat dissipation fans 293 are respectively arranged in the corresponding installation grooves 292.

[0036] A protective net 294 is provided on each of the cooling fans 293 , and the outer wall size of the protective net 294 matches the outer wall size of the cooling fan 293 .

[0037] Specifically, when the dry-type transformer 1 needs to be installed, the dry-type transformer 1 is inserted into the housing 21. At this time, the bottom of the dry-type transformer 1 will first contact the connecting plate 27 and squeeze the first spring 26 downward through the connecting plate 27. At the same time, the connecting plate 27 will also push the connecting column 282 through the fixed block 283 fixed at the bottom of the connecting plate 27, so that the push block 281 at the other end of the connecting column 282 squeezes the second spring 284 along the connecting rod 23 toward the isolation column 24. When the dry-type transformer 1 starts to operate, as the dry-type transformer 1 runs, the vibration generated by the dry-type transformer 1 will be absorbed by the first spring 26 and the second spring 284. At the same time, the cooling fan 293 is started synchronously when the dry-type transformer 1 is running. At this time, the cooling fan 293 will guide the heat accumulated in the housing 21 during the operation of the dry-type transformer 1, so that it enters the installation groove 292 through the cooling fan 293 and is discharged to the housing 21 through the heat dissipation hole 291, thereby preventing the dry-type transformer 1 from malfunctioning due to overheating.

[0038] In one embodiment of the present application, Figure 4 and Figure 5 As shown, a supporting mechanism 3 is provided on the housing 21 .

[0039] The supporting mechanism 3 includes a connecting frame 31 , a connecting seat 32 and a damping rod 33 .

[0040] Among them, the connecting frames 31 are respectively arranged on the outer walls of the shell 21, the connecting seats 32 are respectively arranged on the corresponding connecting frames 31, the damping rod 33 is pivotally connected to the connecting seats 32, and the two ends of the damping rod 33 are respectively pivotally connected to the corresponding connecting seats 32.

[0041] The outer sleeve of the damping rod 33 is provided with a third spring 34, and both ends of the third spring 34 are connected to the corresponding connecting seat 32 respectively.

[0042] A fixing assembly 35 is provided on the housing 21 .

[0043] The fixing assembly 35 includes a fixing plate 351 and a latch 353 .

[0044] The fixing plates 351 are respectively arranged on the housing 21 , the outer walls of the fixing plates 351 are provided with mounting holes 352 , the latches 353 are respectively arranged in the corresponding mounting holes 352 , and the outer walls of the dry-type transformer 1 are respectively provided with limiting holes 354 .

[0045] A fourth spring 355 is disposed inside the mounting hole 352 , and one end of the fourth spring 355 is connected to the inner wall of the mounting hole 352 , while the other end of the fourth spring 355 is connected to the latch 353 .

[0046] One end of the latch 353 passes through the mounting hole 352 and is connected to the linkage rod 356 , and both ends of the linkage rod 356 are connected to the corresponding latches 353 .

[0047] Specifically, when the dry-type transformer 1 is installed, the latch 353 will be squeezed into the mounting hole 352 by the outer wall of the dry-type transformer 1. At the same time, as the dry-type transformer 1 is installed, the mounting hole 352 will be aligned with the limiting hole 354 on the outer wall of the dry-type transformer 1. At this time, under the action of the fourth spring 355, the latch 353 will pop out from the mounting hole 352, thereby fixing the dry-type transformer 1 to the casing 21. When the dry-type transformer 1 is in operation, the casing 21 is in contact with the ground through the connecting frame 31, and the casing 21 is supported on the side of the casing 21 by the damping rod 33 and the third spring 34, so that the vibration generated by the dry-type transformer 1 during operation will not cause the casing 21 to fall down.

[0048] Working principle: When the dry-type transformer 1 needs to be installed, the dry-type transformer 1 is inserted into the housing 21. At this time, the bottom of the dry-type transformer 1 will first contact the connecting plate 27 and squeeze the first spring 26 downward through the connecting plate 27. At the same time, the connecting plate 27 will also push the connecting column 282 through the fixed block 283 fixed at the bottom of the connecting plate 27, so that the push block 281 at the other end of the connecting column 282 squeezes the second spring 284 along the connecting rod 23 toward the isolation column 24. When the dry-type transformer 1 starts to operate, as the dry-type transformer 1 runs, the vibration generated by the dry-type transformer 1 will be absorbed by the first spring 26 and the second spring 284. At the same time, the cooling fan 293 is started synchronously when the dry-type transformer 1 is running. At this time, the cooling fan 293 will guide the heat accumulated in the housing 21 when the dry-type transformer 1 is running, so that it enters the installation groove 292 through the cooling fan 293 and is discharged to the housing 21 through the heat dissipation hole 291, thereby preventing the dry-type transformer 1 from malfunctioning due to overheating.

[0049] In summary, when the dry-type transformer 1 is used, the dry-type transformer 1 is mounted in the housing 21, and the first spring 26 and the second spring 284 are used to absorb the vibration generated by the dry-type transformer 1 during operation to ensure the stability of the dry-type transformer 1. At the same time, the heat that may exist in the housing 21 is evacuated in conjunction with the cooling fan 293.
