Description

Technical Field

[0001] This utility model relates to the field of transformer fan installation technology, specifically a transformer fan installation structure. Background Technology

[0002] The main function of a transformer fan is to dissipate heat and cool the transformer, prevent it from overheating, extend its lifespan, improve system reliability, save energy and reduce consumption, and provide safety protection and automatic control functions. Transformer fans need to be supported by an installation structure during use.

[0003] For example, announcement number CN207112320U (named "A Transformer Fan Mounting Bracket") includes a support plate, baffles, blocks, wing bolts, connecting grooves, connecting blocks, support columns, and connecting rings. The support plate has baffles integrally formed at its four top corners, and these baffles are connected to the inner blocks via wing bolts. The support plate has a connecting groove integrally formed at its bottom, with a square pre-reserved opening at the bottom. The connecting block has a support column integrally formed at its bottom, with a round hole below the support column. The connecting ring is installed in the round hole, and the connecting block is installed in the connecting groove. The transformer fan mounting bracket also includes a pin. The left and right sides of the connecting groove have reserved openings that match the pin. The left and right sides of the connecting block have through circular reserved openings. The connecting block is installed on the connecting groove. The connecting block is fixed on the connecting groove by connecting the pin to the circular reserved opening. The stop block and the stop plate are connected to the heat sink on the side of the transformer by the wing bolt. It is easy to install and is firm and reliable. After the connecting block is installed in the connecting groove, it is fixed by the pin so that the connecting block is stably connected to the support column. The connecting ring installed under the support column facilitates the lifting of the fan and subsequent fixed installation.

[0004] The aforementioned transformer fan mounting bracket uses a butterfly bolt structure to fix the fan to the side of the transformer for heat dissipation. However, since the fan structure is fixed, it cannot provide all-round heat dissipation for the internal coils of the transformer after installation, resulting in poor heat dissipation effect of the fan on the transformer's internal structure. Therefore, we provide a transformer fan mounting structure. Utility Model Content

[0005] The purpose of this utility model is to provide a transformer fan mounting structure to solve the problem mentioned in the background art that the existing transformer fan mounting bracket fixes the fan to the side of the transformer to dissipate heat through a butterfly bolt structure. However, since the fan structure is fixed, it cannot dissipate heat from all directions to the internal coils of the transformer after installation, resulting in poor heat dissipation effect of the fan on the inside of the transformer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transformer fan mounting structure, including a support frame, two support frames are provided, two top platforms are fixed to the upper ends of the two support frames by screws, guide frames are welded to the inner walls of the two top platforms, and a fan carrier is movably arranged between the two guide frames. Also includes: An internal frame is integrally formed and located at the center of the fan carrier. A servo motor is fixed to the lower end of the internal frame with screws. The output shaft of the servo motor passes through the internal frame and is welded with a cooling fan. The coil carrier frame is fixedly mounted on the upper end of the two top frames by screws, and the coil carrier frame is integrally formed with an iron core carrier frame inside, and a heat dissipation air duct is provided between the iron core carrier frame and the coil carrier frame. The support base is located on one side of the support frame base, and the lower end of the support base is fixed with a drive motor by screws. The output shaft of the drive motor passes through the linkage turntable and is welded to the linkage turntable. The upper end of the linkage turntable is integrally formed with a first socket, and a first collar is movably set on the first socket through a bearing sleeve. The end seat is welded to one end of the fan carrier, and the upper end of the end seat is integrally formed with a second sleeve seat. A second sleeve ring is movably mounted on the second sleeve seat through a bearing sleeve.

[0007] Preferably, both guide frames are equipped with movable roller sliders inside, and the two roller sliders and the fan carrier are an integral structure.

[0008] Preferably, the inner wall of the heat dissipation duct is provided with airflow holes, and the inside of the iron core frame is provided with vertical ventilation holes, which are connected to the airflow holes.

[0009] Preferably, three coil frames are provided, and the spacing between two adjacent coil frames is equal.

[0010] Preferably, a traction link is integrally formed between the first and second rings, and the traction link, the linkage turntable, and the end seat are located on the same horizontal line.

[0011] Preferably, a mounting rod is provided at the connection position between the support base and the two guide frames, and the two ends of the mounting rod are welded to the support base and the guide frames respectively.

[0012] Preferably, the first and second collars are respectively connected to the limiting plates at the top of the first and second collars for limiting movement.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a drive motor to rotate a rotating disk, which in turn causes a traction linkage to pull the fan carrier along two guide frames in a reciprocating motion. This allows a single cooling fan to dissipate heat from the three core frames and coil frames of the transformer. Heat dissipation is achieved through cooling ducts, vertical vents, and airflow holes, providing comprehensive cooling of the transformer's cores and coils. This eliminates the need for multiple fans, reducing costs while ensuring efficient heat dissipation. It overcomes the problem of existing transformer fan mounting brackets that use butterfly bolts to fix the fan to the side of the transformer, resulting in poor heat dissipation of the transformer's internal coils due to the fixed fan structure.
