Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and more specifically, to a safety-type dry-type transformer. Background Technology

[0002] In existing technologies, during long-term operation, safety-type dry-type transformers generate a large amount of heat during the power conversion process, causing the transformer body temperature to rise continuously.

[0003] However, due to certain limitations in the design of traditional heat dissipation systems, the heat dissipation effect is often poor, which can easily lead to high temperature accumulation during transformer operation. If the heat cannot be dissipated in a timely and effective manner, it will not only affect the working efficiency of the transformer, but may also cause a decrease in insulation performance due to overheating, or even cause equipment failure or safety accidents.

[0004] Furthermore, traditional heat dissipation components are inconvenient to install and disassemble, often requiring bolt fixing or welding. This makes the replacement or maintenance of components such as heat sinks and cooling fans cumbersome, time-consuming, and labor-intensive. Especially when the transformer operating environment is complex or restricted, maintenance personnel need to spend a lot of time and energy on disassembly, making routine maintenance and emergency repairs difficult and affecting the normal use of the equipment. Therefore, how to improve the heat dissipation efficiency of transformers and optimize the installation and disassembly methods of heat dissipation components to improve the convenience of equipment maintenance has become an urgent problem to be solved in the existing technology.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a safe dry-type transformer with the following advantages:

[0018] This utility model is equipped with a rotating heat dissipation mechanism. A hydraulic cylinder drives the rotating support plate to rotate, which in turn drives the heat-conducting fins and the cooling fan to work together, effectively increasing the surface area for heat exchange and improving heat dissipation efficiency. The rotating support plate is provided with heat dissipation holes. The cooling fan and the transformer are arranged opposite each other, which can more directly conduct heat out of the transformer and avoid equipment failure caused by high temperature. The rotating mechanism allows the heat dissipation device to adjust its angle and position as needed to ensure better heat dissipation effect.

[0019] This utility model features a fan locking mechanism. The engagement of the locking rod and locking tube ensures that the heat-conducting fins and the cooling fan are securely mounted on the rotating support plate, preventing the heat dissipation components from loosening or falling off during rotation. The rotating sleeve is slidably connected through the engagement of the rotary push groove and the extension bracket, and can be stably locked step by step during rotation, avoiding loosening of components due to unstable locking and ensuring long-term stable operation of the heat dissipation equipment. The design of the fan locking mechanism allows the cooling fan and heat-conducting fins to be easily disassembled and replaced, facilitating daily maintenance and repair.

[0020] This utility model incorporates a locking auxiliary mechanism, a combination of an outer fixing ring, an outer rotating ring, and a spinning plate, which enables the rotating sleeve to be locked more stably during rotation, preventing vibration or jamming. The spring rod, by pressing against the top ring, further enhances the fixing effect of the rotating sleeve, ensuring that all components remain stable during use. This locking auxiliary mechanism provides a smooth locking force through the stepwise compression of the spring rod, preventing the rotating sleeve from loosening due to external forces, thereby greatly improving the safety and reliability of the transformer.

[0030] Please see Figures 1-5A safety-type dry-type transformer includes a transformer body 1, a rotating heat dissipation mechanism, a fan locking mechanism, and a locking auxiliary mechanism. The rotating heat dissipation mechanism includes a hydraulic cylinder 2, a rotating support plate 3, heat-conducting fins 4, a cooling fan 5, and cooling holes 6. The hydraulic cylinder 2 is rotatably mounted on the bottom end of the rotating support plate 3. The heat-conducting fins 4 are mounted on the rotating support plate 3 via the fan locking mechanism. The cooling fan 5 is mounted on the heat-conducting fins 4. The cooling holes 6 are formed on the rotating support plate 3. The cooling fan 5 and the transformer are arranged opposite each other. The fan locking mechanism includes a locking tube 7, a locking rod 8, a rotating sleeve 9, and a rotary pusher. The device includes a slot 10, an insertion frame 11, a rotating ring 12, a fixing frame 13, and a stabilizing spring 14. The locking rod 8 can extend into the locking tube 7. The rotating sleeve 9 is rotatably mounted on the outer wall of the locking tube 7. The rotary push groove 10 is set on the inner wall of the rotating sleeve 9. The insertion frame 11 is slidably mounted on the outer wall of the locking tube 7. The insertion frame 11 and the rotary push groove 10 are slidably connected. The rotating ring 12 is set at the bottom of the rotating sleeve 9. The fixing frame 13 is mounted on the outer wall of the locking tube 7. The stabilizing spring 14 on the fixing frame 13 presses against the rotating ring 12 step by step, so that the rotating sleeve 9 is stably locked and rotated step by step.

[0031] In this embodiment, the hydraulic cylinder 2, through its rotational connection with the rotating support plate 3, initiates the operation of the entire cooling system. When the hydraulic cylinder 2 is activated, it pushes the rotating support plate 3 to rotate, thereby causing the heat-conducting fins 4 and the cooling fan 5 to dissipate heat relative to the transformer body 1. The heat-conducting fins 4 and the rotating support plate 3 are connected via a fan locking mechanism. The fins enhance the heat dissipation surface area, while the cooling fan 5 provides airflow through rotation, promoting heat dissipation. The rotating support plate 3 is provided with heat dissipation holes 6. The design of the heat dissipation holes 6 allows heat to be directly released from the rotating support plate 3, thereby increasing heat dissipation efficiency. During rotation, the cooling fan 5 and the transformer body 1... The pressure unit body 1 is positioned opposite to each other to ensure uniform heat dissipation and avoid overheating that could damage the equipment. The clamping tube 7 and the clamping rod 8 work together to fix the heat-conducting fins 4. The clamping rod 8 can extend into the clamping tube 7. The rotating sleeve 9 can rotate freely on the outer wall of the clamping tube 7, driving the rotation of the rotary push groove 10. The rotary push groove 10 works with the extension frame 11. The extension frame 11 can slide and connect to the rotary push groove 10. The rotation can fix or release the heat-conducting fins 4, thus ensuring that the fins are always firmly installed on the rotating support plate 3 and that the heat dissipation device is not affected by external interference.

[0032] The snap-fit ​​auxiliary mechanism includes an outer retaining ring 15, a top ring 16, an outer rotating ring 17, a spinning plate 18, and a spring rod 19. The outer retaining ring 15 is fixedly installed on the outer wall of the snap-fit ​​tube 7. The outer rotating ring 17 is rotatably installed on the outer wall of the snap-fit ​​tube 7. The spinning plate 18 is installed at the bottom end of the outer rotating ring 17. The spring rod 19 is set on the outer retaining ring 15. The top ring 16 is installed at the top end of the rotating sleeve 9. The spinning plate 18 can press against the spring rod 19, so that the spring rod 19 extends into the top ring 16, thereby fixing the rotating sleeve 9 in the rotation direction.

[0033] In this embodiment, the outer retaining ring 15 is fixedly installed on the outer wall of the clamping tube 7, and the outer rotating ring 17 is installed on the clamping tube 7 by limiting rotation, which further enhances the stability of the clamping tube 7. When the spinning plate 18 presses against the spring rod 19, the spring rod 19 applies pressure to the top ring 16, thereby stabilizing the rotating sleeve 9 in the rotation direction. The design of the spinning plate 18 and the spring rod 19 effectively locks the rotating sleeve 9, ensuring that the entire fan clamping mechanism can operate stably in complex environments such as high temperature and high pressure.

[0034] Please see Figures 1-5 As a supplementary embodiment of a safety-type dry-type transformer for the rotating heat dissipation mechanism, fan locking mechanism, and locking auxiliary mechanism: A base frame 20 is installed at the bottom end of the transformer body 1, and casters 21 are installed at the bottom end of the base frame 20. A mounting plate 22 is installed at the top end of the base frame 20, and one end of the hydraulic cylinder 2 is rotatably connected to the mounting plate 22. One end of the rotating support plate 3 is rotatably connected to the mounting plate 22. Fixing plates 23 are installed at both ends of the heat-conducting fins 4, and the locking tube 7 is fixedly installed on the fixing plate 23. One end of the snap-fit ​​rod 8 extends through the pivot plate 3 and the mounting plate 22, and engages with the snap-fit ​​tube 7 to install the heat-conducting fins 4 onto the pivot plate 3. The bottom end of the rotating sleeve 9 is equipped with a bottom block 24, and the rotating ring 12 is installed on the bottom block 24. The rotation of the rotating sleeve 9 drives the rotating ring 12 on the bottom block 24 to rotate within the fixed frame 13. One end of the extension frame 11 is equipped with a swivel plate 25, and the swivel plate 25 is slidably connected with the swivel push groove 10. The rotation of the swivel push groove 10 drives the extension frame 11 to extend into or away from the snap-fit ​​rod 8.

[0035] More specifically, the transformer body 1 is initially started by electric drive. As the transformer's operating temperature rises, the heat dissipation demand gradually increases. During operation, the hydraulic cylinder 2 pushes the rotating support plate 3 to rotate. The rotating support plate 3 drives the heat-conducting fins 4 and the cooling fan 5 to work together. The rotation of the cooling fan 5 removes excess heat through airflow. The fan locking mechanism ensures a stable connection between the heat-conducting fins 4 and the rotating support plate 3, preventing the heat-conducting fins 4 from loosening or falling off under high-temperature conditions. Simultaneously, the locking auxiliary mechanism further applies a stabilizing force to the rotating sleeve 9 through the spinning plate 18 and spring rod 19, preventing accidental loosening of the rotating sleeve 9. The design of the base frame 20 and the casters 21 allows for easy movement and position adjustment of the equipment, providing greater flexibility and convenience. The connection of the hydraulic cylinder 2 and the rotation of the rotating support plate 3 not only improve heat dissipation efficiency but also enhance the transformer's adaptability to complex environments, ensuring long-term stable operation of the equipment.

[0036] In summary, during the use or operation of the overall equipment: when the cooling mechanism needs to be rotated, the hydraulic cylinder 2, through its connection with the rotating support plate 3, initiates the operation of the entire cooling system. When the hydraulic cylinder 2 is activated, it pushes the rotating support plate 3 to rotate, thereby driving the heat-conducting fins 4 and the cooling fan 5 to dissipate heat relative to the transformer body 1. The heat-conducting fins 4 and the rotating support plate 3 are connected through a fan locking mechanism. The fins enhance the heat dissipation surface area, while the cooling fan 5 provides airflow through rotation, promoting heat dissipation. The rotating support plate 3 is equipped with heat dissipation holes 6. The design of the heat dissipation holes 6 allows heat to be released directly from the rotating support plate 3, thereby increasing heat dissipation efficiency. During rotation, the cooling fan 5 and the transformer body 1 are positioned opposite each other, ensuring uniform heat dissipation and preventing overheating that could damage the equipment.

[0037] When the fan clamping mechanism is required to operate, the clamping tube 7 and the clamping rod 8 cooperate to fix the heat-conducting fins 4. The clamping rod 8 can extend into the clamping tube 7. Through the control of the rotating sleeve 9, the rotating sleeve 9 can rotate freely on the outer wall of the clamping tube 7, driving the rotation of the rotary push groove 10. The rotary push groove 10 cooperates with the extension frame 11. The extension frame 11 can slide and connect to the rotary push groove 10. By rotating, the heat-conducting fins 4 can be fixed or released, thereby ensuring that the fins are always firmly installed on the rotating support plate 3, ensuring that the heat dissipation device is not disturbed by the outside world.

[0038] When the auxiliary clamping mechanism is required to operate, the outer retaining ring 15 is fixedly installed on the outer wall of the clamping tube 7, and the outer rotating ring 17 is installed on the clamping tube 7 by limiting rotation, which further enhances the stability of the clamping tube 7. When the swivel plate 18 presses against the spring rod 19, the spring rod 19 applies pressure to the top ring 16, thereby stabilizing the rotating sleeve 9 in the rotation direction. The design of the swivel plate 18 and the spring rod 19 effectively locks the rotating sleeve 9, ensuring that the entire fan clamping mechanism can operate stably in complex environments such as high temperature and high pressure.

[0039] The transformer body 1 is initially started by electric drive. As the transformer's operating temperature rises, the heat dissipation demand gradually increases. During operation, the hydraulic cylinder 2 pushes the rotating support plate 3 to rotate. The rotating support plate 3 drives the heat-conducting fins 4 and the cooling fan 5 to work together. The rotation of the cooling fan 5 removes excess heat through airflow. The fan locking mechanism ensures a stable connection between the heat-conducting fins 4 and the rotating support plate 3, preventing the heat-conducting fins 4 from loosening or falling off under high-temperature conditions. Simultaneously, the locking auxiliary mechanism further applies a stabilizing force to the rotating sleeve 9 through the spinning plate 18 and spring rod 19, preventing accidental loosening of the rotating sleeve 9. The design of the base frame 20 and the casters 21 allows for easy movement and adjustment of the equipment, providing greater flexibility and convenience.
