Description

Technical Field

[0001] This utility model relates to the technical field of dry-type transformers, and specifically to a fan installation structure for a dry-type transformer. Background Technology

[0002] The dry-type transformer fan is one of the important auxiliary devices in a dry-type transformer. Its main function is to cool the transformer and ensure its normal operation. When the internal temperature of the transformer rises, the dry-type transformer fan will automatically start, expelling the hot air from the transformer coils and lowering the transformer temperature. During the use of the dry-type transformer, the fan also circulates air and dries the insulation, ensuring the normal operation of the transformer.

[0003] However, due to the angular deviation between the fan duct and the transformer air duct, only a small portion of the fan's air volume can effectively enter the transformer coil air duct, which greatly affects the transformer's heat dissipation effect.

[0004] Therefore, the existing fan structures of dry-type transformers suffer from low reliability due to the aforementioned technical problems. Thus, improving the reliability of the fan structures in dry-type transformers is a problem that needs to be solved in this field. Utility Model Content

[0023] Example 1:

[0024] Existing transformers suffer from angular deviation between the fan duct and the transformer air duct. To address this technical problem, this utility model provides a fan installation structure for dry-type transformers. This structure allows for multi-angle adjustment of the fan duct direction, making operation simple and convenient, and maximizing fan efficiency.

[0025] See Figures 1-2 The fan installation structure of the dry-type transformer provided by this utility model includes a lower clamp 1, a fan unit 2, a fixing unit 3, and a rotation adjustment unit 4.

[0026] In this design, the lower clamp 1 is preferably a flat plate structure, which minimizes airflow obstruction. The lower clamp has elongated holes running left and right for connection to the rotary adjustment unit 4.

[0027] The rotation adjustment unit 4 is used to adjust the angle of the fan unit 2. The rotation adjustment unit 4 includes two sets of fan fixing brackets. The two sets of fan fixing brackets are symmetrically arranged, and their ends are movably connected to the elongated holes of the lower clamp 1 through a connecting piece. The fan fixing brackets can be adjusted laterally relative to the lower clamp 1 to adjust the left and right position relationship of the fan unit 2.

[0028] The middle area of ​​the two symmetrically arranged fan mounting brackets forms the mounting space for the fixing unit 3. Each fan mounting bracket is provided with a pin hole 41 and an arc-shaped hole 42. The fixing unit 3 is set in the two fan mounting brackets. The pin hole 41 and the arc-shaped hole 42 on the fan mounting brackets can be used with connectors to make a movable connection with the fixing unit 3.

[0029] The fixing unit 3 is used to connect the fan unit 2. The fixing unit 3 has a first stud 32 and a second stud 33 on both sides. The first stud 32 corresponds to the pin hole 41 of the fan fixing bracket and can rotate in the pin hole 41. The second stud 33 corresponds to the arc-shaped hole 42 of the fan fixing bracket and can move along the arc-shaped hole 42 and be fixed with a nut.

[0030] The fixing unit 3 is connected to the pin hole 41 and the arc hole 42 on the fan fixing bracket by the first stud 32 and the second stud 33 respectively. It can rotate along the fan fixing bracket relative to the lower clamp 1 to adjust the angle of the fan unit 2 and adjust the vertical position of the fan unit 2.

[0031] The mounting end face of the fixed unit 3 is provided with several adjustable mounting holes 31. By connecting the fan unit 2 to different adjustable mounting holes 31, the relative front and rear positions of the fan unit 2 can be adjusted.

[0032] The fan installation structure of the dry-type transformer constructed by the above scheme is simple in structure, highly versatile, and can adjust the direction of the fan duct from multiple directions and angles, including up and down, left and right, front and back. It is simple and convenient to operate and can make the most efficient use of the fan.

[0033] Example 2:

[0034] This embodiment is based on Embodiment 1, where the mounting end face of the fixing unit 3 in Embodiment 1 is a planar structure. (See also...) Figure 3 Based on embodiment 1, this embodiment first opens a groove 35 on the mounting end face of the fixing unit 3, so that the fan unit 2 can be set in the groove 35 and the fan unit 2 can be limited to a certain extent.

[0035] Several adjustable mounting holes 31 are provided in the groove 35. By connecting the fan unit 2 to different adjustable mounting holes 31, the relative front and rear positions of the fan unit 2 can be adjusted. This can further improve the reliability of the fan unit 2 installation.

[0036] Example 3:

[0037] This embodiment is based on embodiment 1, see [link to embodiment 1] Figure 4 Rubber layers 34 are provided at both ends of the fixed unit 3 relative to the fan fixed bracket, which can generate a certain amount of friction with the fan fixed bracket during rotation to ensure stability during rotation.

[0038] Secondly, participate Figure 5 A friction layer 43 can be provided on the end face of the fan mounting bracket. This friction layer 43 can prevent the mounting unit 3 from rubbing against the fan mounting bracket when it rotates, and can also cooperate with the rubber layer 34 on the mounting unit 3 to further improve the stability during rotation.
