Description

Technical Field

[0001] This utility model belongs to the field of dry-type transformer technology, specifically relating to a noise-reducing novel dry-type transformer. Background Technology

[0002] A dry-type transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core).

[0003] Existing dry-type transformers generate significant noise during operation. Since they lack noise reduction capabilities, the noise can negatively impact the health of nearby residents. Therefore, noise reduction equipment needs to be installed on the exterior of the dry-type transformer. However, because the input and output lines of a dry-type transformer are located at the top, with the installation end at the bottom, noise reduction measures can only be implemented around the transformer's perimeter after installation. The top and bottom of the transformer cannot be fitted with noise reduction devices, thus reducing the effectiveness of such devices. Utility Model Content

[0004] The purpose of this invention is to provide a noise-reducing novel dry-type transformer to solve the problems mentioned in the background art.

[0006] Preferably, the mounting mechanism includes two symmetrically mounted mounting brackets, with a mounting area for mounting the transformer body formed between the two mounting brackets. The top of the transformer body is provided with a mounting seat for connecting the mounting brackets, and the end of the mounting seat is provided with a mounting lug for connecting to the mounting brackets by screws.

[0007] Preferably, the top plate is also provided with a plurality of electrical terminals for wiring, and one end of each of the plurality of electrical terminals extends through into the installation area.

[0008] Preferably, the connector includes four mounting rods and four positioning sleeves. The top ends of the four mounting rods are respectively welded to the four corners of the bottom of the top plate. The four positioning sleeves are respectively installed around the top of the housing. Each positioning sleeve has a through hole that is fitted onto the mounting rod. Each positioning sleeve is provided with a positioning element for height positioning on the mounting rod.

[0009] Preferably, the positioning element includes a locking bolt, which extends outward through the through hole, and one end of the locking bolt abuts against the mounting rod.

[0010] Preferably, the support mechanism includes two longitudinally mounted mounting columns, which are symmetrically mounted on both sides of the housing, and the two ends of the mounting beam are respectively mounted on the mounting columns on both sides.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) This utility model uses an added support mechanism, mounting beam, top plate and shell to install and fix the transformer body from above. After installation, the first noise reduction layer and the second noise reduction layer are installed in six directions of the transformer body through the top plate and shell, which improves the noise reduction effect of the equipment.

[0013] (2) By adding two mounting brackets, mounting bases and mounting ears, this utility model makes it easy to suspend the transformer body under the top plate and to detachably install the transformer body on the top plate.

[0014] (3) By adding multiple terminals pre-installed on the top plate, this utility model can avoid the connection between the terminals and the transformer body affecting the noise reduction equipment covering the transformer body, thereby further improving the noise reduction effect of the equipment.

The transformer body 10 is suspended and installed at the bottom of the top plate 3 through the mounting mechanism. At this time, the transformer body 10 is connected to the external circuit through the power terminal 14. The housing 7 is then fastened to the top plate 3 through the connectors, thereby installing the transformer body 10 between the top plate 3 and the housing 7. At this time, the first noise reduction layer 8 and the second noise reduction layer 9 wrap the transformer body 10, which facilitates noise reduction of the transformer body 10 in multiple directions and improves the noise reduction effect of the equipment.

[0024] Furthermore, to facilitate the suspension support of the top plate 3, refer to Figure 1 As shown, the support mechanism includes two longitudinally mounted mounting columns 1, which are symmetrically mounted on both sides of the housing 7. The two ends of the mounting beam 2 are respectively mounted on the mounting columns 1 on both sides. Both mounting columns 1 are prefabricated longitudinally at their installation positions. The mounting beam 2 provides a suspended installation position for the top plate 3 between the two mounting columns 1, thus facilitating the suspended installation of the top plate 3.

[0025] In this utility model, combined with Figure 2-3As shown, the installation mechanism of this embodiment includes two symmetrically installed mounting brackets 11, and an installation area for installing the transformer body 10 is formed between the two mounting brackets 11. The top of the transformer body 10 is provided with a mounting seat 15 for connecting the mounting brackets 11, and the end of the mounting seat 15 is provided with a mounting ear 13 for connecting to the mounting brackets 11 by screws.

[0026] As described above, when using the installation mechanism provided by this utility model, the two mounting brackets 11 in the installation mechanism provide an installation position for the transformer body 10 below the top plate 3. The transformer body 10 is easily connected to the mounting brackets 11 through the mounting seat 15 and the mounting ear 13, thereby facilitating the suspension of the transformer body 10 below the top plate 3.

[0027] In this utility model, combined with Figure 1-4 As shown, the connector in this embodiment includes four mounting rods 6 and four positioning sleeves 5. The top ends of the four mounting rods 6 are respectively welded to the four corners of the bottom of the top plate 3. The four positioning sleeves 5 are respectively installed around the top of the housing 7. Each positioning sleeve 5 has a through hole 12 that is sleeved on the mounting rod 6. Each positioning sleeve 5 is provided with a positioning element for height positioning on the mounting rod 6.

[0028] Combination Figure 1-2 and Figure 4 As shown, the positioning component includes a locking bolt 4, which extends outward to the through hole 12, and one end of the locking bolt 4 abuts against the mounting rod 6.

[0029] As described above, when the transformer body 10 is installed below the top plate 3 using the connector provided by this utility model, four positioning sleeves 5 are respectively fitted onto the four mounting rods 6 through the through holes 12, and the positioning sleeves 5 are raised on the mounting rods 6, thereby driving the housing 7 to cover the top plate 3. At this time, the locking bolts 4 are tightened to fix the positioning sleeves 5 on the mounting rods 6, thereby installing the transformer body 10 between the top plate 3 and the housing 7, and then the first noise reduction layer 8 and the second noise reduction layer 9 are respectively on the outside of the transformer body 10.
