Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, specifically to an energy storage dry-type transformer. Background Technology

[0002] Dry-type transformers are important electrical equipment. Their cores and windings are not immersed in insulating oil but are directly exposed to air or cooled by other means. Dry-type transformers typically consist of low-voltage and high-voltage windings, both encapsulated with high-performance insulating materials. This encapsulation method not only improves the transformer's mechanical strength but also provides superior moisture and dust resistance, enabling stable operation in various harsh environments. A dry-type transformer comprises a core, windings, insulating materials, a base frame, and lifting lugs. The core is made of high-quality silicon steel sheets stacked together to concentrate the magnetic field. The windings are divided into primary and secondary windings, made of copper or aluminum wire, and voltage transformation is achieved through the turns ratio. The insulating material isolates the windings and core, preventing short circuits and leakage. The base frame provides mechanical support, and the lifting lugs are used for mounting and securing the transformer. The working principle of a dry-type transformer is based on the law of electromagnetic induction. When the primary winding is energized, it generates an alternating magnetic field, which is transmitted to the secondary winding through the iron core. The secondary winding cuts the magnetic field lines and induces an electromotive force, thereby realizing voltage transformation and energy transfer to provide electrical energy to the load.

[0003] In existing technologies, small energy storage dry-type transformers are typically moved and installed initially using lifting lugs in conjunction with a crane. However, in practical applications, small energy storage dry-type transformers sometimes require secondary movement, especially during equipment commissioning, maintenance, or redeployment. Since the distance of these secondary movements is usually short, using the traditional method of lifting lugs and a crane is not only cumbersome but also requires repeated loading and unloading, consuming significant time and manpower, and greatly reducing movement efficiency. Furthermore, frequent use of cranes for movement may increase the risk of equipment damage, affecting its stability and lifespan. Therefore, this invention proposes an energy storage dry-type transformer to address these problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: an energy storage dry-type transformer, comprising: a dry-type transformer body 1 and a base frame 2 fixedly installed at the bottom of the dry-type transformer body 1. The dry-type transformer body 1 is composed of components such as an iron core, windings, insulating materials, the base frame 2, and lifting lugs, all of which are existing technologies and will not be described in detail here. The base frame 2 provides fixed support for the entire dry-type transformer body 1. Support components are provided on both sides of the bottom of the base frame 2, which provide stable support for the base frame 2 and the dry-type transformer body 1. Movable components are provided at both ends of the base frame 2, which facilitate the installation of the entire transformer body. For short-distance transport of the dry-type transformer body 1, the support assembly includes an anti-slip support plate 3. The anti-slip support plate 3 contacts the ground, increasing friction and thus improving its stability. The upper surface of the anti-slip support plate 3 is fixedly connected to the bottom end of a large screw 4. A limit plate 5 is fixedly connected to the top end of the large screw 4. The limit plate 5 is slidably sleeved on a limit rod 6. When the limit plate 5 moves, it is limited by the limit rod 6. A worm gear 7 is provided on the lower side of the limit plate 5. The worm gear 7 is threadedly connected to the large screw 4. A worm 8 meshes with one side of the worm gear 7, and the worm 8 meshes with the worm gear 7 for transmission. The component includes a wheel frame 9, on one side of which a load-bearing wheel 10 is rotatably mounted. The wheel frame 9 supports the load-bearing wheel 10. The load-bearing wheel 10 rotatably mounted on the wheel frame 9 effectively distributes weight and improves transport stability. The other side of the wheel frame 9 is fixedly connected to one end of a support rod 11, and the other end of the support rod 11 is fixedly connected to a rotating frame 12. The rotating frame 12 is rotatably fitted inside a fixed housing 13, with both sides of the rotating frame 12 movably engaged with the fixed housing 13, allowing it to rotate within the fixed housing 13. The fixed housing 13 is welded and fixed to the end of the base frame 2, thus ensuring... The fixed housing 13 ensures stable installation. One side of the rotating frame 12 is slidably connected to the drive block 14. One side of the drive block 14 has a concave arc surface, and protrusions are provided on both sides of the concave arc surface. The rotating frame 12 rotates by sliding between the concave arc surface and the protrusions and the drive block 14. The drive block 14 is threaded onto the small screw 15. The small screw 15 is rotatably installed in the fixed housing 13. The fixed housing 13 provides stable support for the small screw 15. The support rod 11, the large screw 4, and the small screw 15 are all made of high-strength alloy steel, which ensures that their material properties will not deform or fail during long-term use.

[0023] The lower surface of the anti-slip support plate 3 is provided with anti-slip texture. The anti-slip texture on the lower surface of the anti-slip support plate 3 increases its friction with the ground, thereby improving stability. One end of the limiting rod 6 is welded and fixed to the base frame 2. A limiting ring 16 is fixedly sleeved on the limiting rod 6. The limiting ring 16 limits the position of the limiting plate 5. The two sides of the worm gear 8 are rotatably sleeved in the support seat 17. The support seat 17 is welded and fixed to the base frame 2. The support seat 17 provides stable support for the worm gear 8. One end of the worm gear 8 is fixedly connected to a handwheel 18. The worm gear 8 can be rotated by rotating the handwheel 18. The worm gear 8 meshes with the worm wheel 7. The lower side of the worm wheel 7 is movably engaged with the top of the support sleeve 19. The bottom of the support sleeve 19 is welded and fixed to the base frame 2. The support sleeve 19 is T-shaped and matches the annular groove opened at the bottom of the worm wheel 7, so as to effectively limit and support the worm wheel 7 and ensure its stability during rotation.

[0024] The rotating frame 12 is fixedly connected to the support rod 11 by a fixing pin. A horizontal plate 20 is provided on one side of the rotating frame 12, and a vertical plate 21 is provided on the other side of the rotating frame 12. Both the horizontal plate 20 and the vertical plate 21 are fixedly connected to the inner wall of the fixed shell 13. Both the horizontal plate 20 and the vertical plate 21 limit the rotation of the rotating frame 12. The drive block 14 is slidably engaged in the fixed shell 13. A limit strip is provided on the top of the fixed shell 13. One side of the drive block 14 is slidably engaged in the limit strip, thereby limiting the drive block 14. One end of the small screw 15 is rotatably sleeved in the fixed shell 13. The other end of the small screw 15 is fixedly connected to the output end of the synchronous motor 22 through a coupling. The synchronous motor 22 is fixedly installed in the fixed shell 13. A limit seat 23 is fixedly installed on one side of the synchronous motor 22. The small screw 15 is rotatably sleeved in the limit seat 23. The limit seat 23 stably supports the small screw 15. The synchronous motor 22 is electrically connected to an external terminal control device.

[0025] In actual use, initially, the wheel frame 9 is horizontal. When the dry-type transformer body 1 is initially hoisted and transported, it can be lifted by the lifting lugs fixedly installed on the top of the dry-type transformer body 1, thereby transporting it to the required position. When it reaches the appropriate position and is lowered close to the ground, the handwheel 18 is turned, causing the handwheel 18 to drive the worm 8 to rotate under the limit of the support seat 17. The worm 8 will then mesh with the worm wheel 7, which rotates under the limit support of the support sleeve 19. Since the worm wheel 7 is threadedly connected to the large screw 4, it will drive the large screw 4 to move. The large screw 4 moves downward in the sliding cooperation of the limit plate 5 and the limit rod 6, which in turn drives the anti-slip support plate 3 to move closer to the ground until... The limiting ring 16 abuts against the limiting plate 5. At this point, the handwheel 18 stops rotating, and the dry-type transformer body 1 continues to descend until the anti-slip support plate 3 contacts the ground, thus completing the initial hoisting and transfer of the dry-type transformer body 1. The anti-slip support plate 3 provides stable support for the entire dry-type transformer body 1. In addition, the self-locking property of the worm gear 7 and worm 8 further enhances the stability of the anti-slip support plate 3. When a secondary short-distance transfer of the dry-type transformer body 1 is required, four synchronous motors 22 are first started through the external terminal control equipment. The synchronous motors 22 drive the small screw 15 to rotate under the support and limitation of the fixed shell 13 and the limiting seat 23 through the coupling connection. Due to the threaded engagement between the drive block 14 and the small screw 15, it will... The drive block 14 moves, and under the limitation of the limiting strip on the top of the fixed shell 13, the drive block 14 moves laterally, thus moving towards the synchronous motor 22. Simultaneously, the drive block 14, through sliding engagement with the concave arc surface and protrusion on the rotating frame 12, pushes the rotating frame 12 to move. The two sides of the rotating frame 12 are movably engaged within the fixed shell 13, thereby achieving rotation of the rotating frame 12. The rotating frame 12, through the connection of the support rod 11, drives the wheel frame 9 to move towards the ground until the wheel frame 9 drives the load-bearing wheel 10 to contact the ground. At this point, by twisting the handwheel 18 in the opposite direction, the anti-slip support plate 3 is indirectly raised, lifting it a certain distance off the ground. Then, through the sliding engagement between the load-bearing wheel 10 and the ground, the anti-slip support plate 3 can be lifted. The entire dry-type transformer body 1 is moved and transported by pushing. Installing several load-bearing wheels 10 can effectively distribute the weight, improve the stability of the transport, and reduce the impact of vibration on the equipment, ensuring safety and equipment protection during the transport process. When it reaches the appropriate position, the anti-slip support plate 3 is indirectly brought into contact with the ground by turning the handwheel 18, which supports the entire dry-type transformer body 1 again. Then, the synchronous motor 22 is controlled to rotate in the opposite direction until the wheel frame 9 is reset to a horizontal state, thus completing the secondary transport. This avoids the problem of using a combination of lifting lugs and cranes to transport the dry-type transformer body 1 when the secondary transport distance is short. This method is not only cumbersome to operate, but also requires repeated loading and unloading, which consumes a lot of time and manpower and greatly reduces the efficiency of the transport.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
