Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a dry-type transformer with a low-voltage winding support structure. Background Art

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and other places. Simply put, a dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil.

[0003] A dry-type transformer with the publication number CN211699953U has been found. The transformer comprises a transformer body and a clamp. The transformer body includes an iron core, a high-voltage winding, and a low-voltage winding sleeved on the iron core. The high-voltage and low-voltage windings are cast into an integrated structure. A boss is provided at the end of the integrated structure, which is connected to the clamp. This dry-type transformer has a simple structure and is easy to manufacture.

[0004] In response to the aforementioned related technologies, the inventors believe that the number of turns of the low-voltage winding in existing dry-type transformers varies depending on the specific operating environment. To ensure overall operational stability, the winding needs to be fixed in the middle of the core. However, the support structure in existing dry-type transformers cannot be adjusted, which results in the low-voltage winding being positioned out of center, thus affecting the overall performance of the dry-type transformer. To this end, we propose a dry-type transformer with a low-voltage winding support structure. Utility Model Content

In order to ensure the overall stability of use, the winding needs to be fixed in the middle position of the iron core, but the support structure in the existing dry-type transformer cannot be adjusted, which makes the position of the low-voltage winding unable to be centered, thereby affecting the overall use effect of the dry-type transformer.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0010] Preferably, a rotating rod is provided on the rotating head, and a rubber sleeve is nested on the rotating rod.

[0011] Preferably, the upper transverse plate is provided with a plurality of hanging rings, and the plurality of hanging rings are evenly distributed on the two upper transverse plates.

[0012] Preferably, a first fixing block and a second fixing block are respectively provided on the outer walls of the upper transverse plate and the lower transverse plate, and a long-rod bolt is provided between the first fixing block and the second fixing block.

[0013] Preferably, a support rod is fixed to the bottom outer wall of the lower transverse plate by bolts, and there are two support rods, which are symmetrically arranged between the lower transverse plates.

[0014] Preferably, a fan is installed between the two support rods, and the air outlet of the fan is arranged at an angle.

A rotating head 17 is provided at one end of the first screw 14 away from the support plate 15. The rotating head 17 and the first screw 14 are integrated into a structure, which can facilitate the separation of the first screw 14 from the connecting block 13 during use.

[0038] The utility model discloses a dry-type transformer with a low-voltage winding support structure. A fan 11 is installed between two support rods 12.

[0039] Example 3

[0040] Based on the second embodiment, Figure 1-3 As shown, the utility model is a dry-type transformer with a low-voltage winding support structure.
