Description

Technical Field

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

[0002] Power transformers are core equipment in power systems for voltage transformation, power distribution, and transmission. Their safety and reliability directly affect the stable operation of the power grid. Since power transformers are usually installed outdoors, they are easily damaged by extreme weather or external impacts, which can lead to damage to internal components and power transformer failure. Furthermore, long-term exposure to the outdoor environment causes the surface coating of power transformers to age and peel off, metal parts to rust, and insulation performance to decline, thus shortening the service life of power transformers.

[0003] According to announcement number CN221446914U, a power transformer with a protective structure includes a main body, with an external mounting frame and a protective frame. Mounting plates are fixedly connected to both sides of the protective frame. The mounting plates have fixing mechanisms for connection and fixation, including mounting blocks. One side of the mounting block is fixedly connected to the mounting frame. The mounting block is used for connection and positioning of the mounting plate, and includes a limiting post and a connecting plate. The mounting block engages with the mounting plate via the limiting post. The bottom of the mounting plate has a mounting groove, and the sides of the mounting block have multiple limiting grooves. This utility model utilizes the cooperation of the mounting block, limiting post, connecting plate, operating plate, mounting frame, and protective frame. The mounting plate engages with the mounting block, the operating plate connects the limiting post to the mounting block, and the connecting plate connects adjacent limiting posts. This facilitates the separation of the mounting frame and protective frame, enabling emergency handling of the main body and convenient operation.

[0004] As described above, power transformers require protection during installation and use. Existing outdoor power transformers lack protective measures and are easily damaged in extreme weather or external impacts, leading to damage to internal components and transformer malfunctions. Furthermore, long-term exposure to the outdoor environment causes the surface coating of the power transformer to age and peel off, metal parts to rust, and insulation performance to decline, thus shortening the service life of the power transformer. To address the aforementioned problems, a power transformer with a protective structure has been proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-4 The power transformer shown includes a power transformer body 1 and a mounting base 2. A base 3 is fixedly connected to a symmetrical position at the bottom of the power transformer body 1. The base 3 is mounted on the mounting base 2. Support components 4 are installed on the outer sides of the two bases 3. A protective cover 5 is provided on the surface of the power transformer body 1. Two sides of the lower end of the protective cover 5 are engaged with the support components 4. A positioning mechanism 6 is provided at the engagement position between the support components 4 and the protective cover 5. By installing the protective cover 5 on the power transformer body 1, the power transformer body 1 can be protected. Furthermore, the stability of the protective cover 5 installation is enhanced by the cooperation of the support components 4 and the positioning mechanism 6. Simultaneously, the support rod 9 and water baffle 10 on the top of the protective cover 5 further enhance the sunshade and waterproofing effect on the power transformer body 1. Therefore, the power transformer body 1 is prevented from being exposed to the outside environment for a long time, thus protecting the power transformer body 1 and extending its service life.

[0023] The protective cover 5 has protective frames 7 hinged to both sides. The protective frames 7 are equipped with grid mesh 8. The combination of protective frames 7 and grid mesh 8 ensures ventilation and heat dissipation of the main body 1 of the power transformer while also providing protection.

[0024] Support rods 9 are fixedly connected to the top of the protective cover 5 around its perimeter. A water baffle 10 is fixedly connected to the top of the support rods 9. The two ends of the water baffle 10 are set with sloping surfaces. A through slot 11 is opened at the center of the top of the protective cover 5 to facilitate the electrical connection of the power transformer body 1. Waterproof blocks 12 are set around the through slot 11. The support rods 9 can support the water baffle 10. The sloping surfaces at both ends of the water baffle 10 can guide rainwater to slide off, effectively preventing rainwater from entering, protecting the electrical performance of the power transformer body 1, and extending its service life. At the same time, the through slot 11 is opened to facilitate the connection of the connectors on the power transformer body 1 to the outside. The water baffle blocks further prevent rainwater from entering the interior of the protective cover 5 through the through slot 11.

[0025] The support assembly 4 includes a support plate 41, which is L-shaped. One end of the support plate 41 is fixedly connected to the outer side of the base 3 of the power transformer body 1 by fasteners 42. The other end of the support plate 41 is fixedly connected to a limiting block 43. A slot 44 is formed between the limiting block 43 and the outer end of the support plate 41 to cooperate with the protective cover 5. The positioning mechanism 6 is set on the limiting block 43. The support plate 41 can be connected to the base 3 by fasteners 42. The slot 44 formed between the limiting block 43 and the support plate 41 can provide a locking and limiting function for the protective cover 5. Therefore, it plays a supporting role for the power transformer body 1 and provides a structural foundation for the installation of the protective cover 5, which facilitates the installation and fixing of the protective cover 5 and makes the entire protection structure more stable.

[0026] The positioning mechanism 6 includes a positioning plate 61. Positioning posts 62 are fixedly connected at equal intervals on the side of the positioning plate 61 near the limiting block 43. Positioning holes 63 are opened on the surfaces of the limiting block 43 and the protective cover 5 at positions corresponding to the positioning posts 62. The positioning posts 62 are inserted into the positioning holes 63. Adjustment components 64 are provided at both ends of the limiting block 43 to adjust the position of the positioning plate 61. During installation, the positioning posts 62 are inserted into the positioning holes 63, and the position of the positioning plate 61 can be adjusted by adjusting the components 64, so that the positioning posts 62 can better cooperate with the positioning holes 63, ensuring the accuracy and stability of the installation position of the protective cover 5 on the support component 4, avoiding displacement of the protective cover 5 during use, and enhancing the reliability of the entire protective structure.

[0027] The adjusting assembly 64 includes two bidirectional lead screws 641. The two ends of the two bidirectional lead screws 641 are rotatably connected to the two ends of the limiting block 43 via bearings. The two ends of the positioning plate 61 are fitted with threaded sleeves 642 that cooperate with the bidirectional lead screws 641. An adjusting block 643 is fixedly connected to the center of the bidirectional lead screws 641. The surface of the adjusting block 643 is provided with anti-slip grooves. By rotating the adjusting block 643 at the center of the bidirectional lead screws 641, the bidirectional lead screws 641 rotate, driving the threaded sleeves 642 and the positioning plate 61 to move, thereby adjusting the position of the positioning post 62. This allows for fine-tuning of the position of the positioning post 62 during installation according to the actual situation, improving installation efficiency.

[0028] An inclined plate 13 is fixedly connected to the bottom of the outer side of the protective cover 5. The inclined plate 13 is located above the outer end of the support plate 41. With the cooperation of the inclined plate 13, rainwater falling from above can be blocked from flowing into the support plate 41 along the protective cover 5, thereby enhancing the waterproof effect and preventing rainwater from eroding the connection between the support plate 41 and the positioning mechanism 6 and the base 3.

[0029] In practical use, when using the protection device, firstly, the main body 1 of the power transformer is securely installed on the mounting base 2 through the base 3 at the bottom symmetrical position. Then, one end of the support plate 41 of the support component 4 is fixedly connected to the outside of the base 3 using fasteners 42. The limiting block 43 at the other end of the support plate 41 forms a groove 44 with the outer end, which is used to engage the lower two sides of the protective cover 5. When installing the protective cover 5, the protective cover 5 is placed on the surface of the main body 1 of the power transformer, so that the lower two sides of the protective cover 5 are engaged in the groove 44. At the same time, the positioning mechanism 6 plays a role, inserting the positioning pin 62 on the positioning plate 61 into the positioning hole 63 corresponding to the limiting block 43 and the surface of the protective cover 5. By adjusting the adjusting component 64, the adjusting block 643 at the center of the bidirectional screw 641 is rotated, which drives the threaded sleeve 642 and the positioning plate 61 to move, and the position of the positioning pin 62 is finely adjusted to ensure the fixation of the installation position of the protective cover 5.

[0030] During use, the protective frame 7 and the installed grid mesh 8 on the protective cover 5, which are hinged together, provide protection while ensuring ventilation and heat dissipation of the main body 1 of the power transformer. The water baffle 10 supported by the support rods 9 around the top has sloping surfaces at both ends to guide rainwater to slide down. The waterproof blocks 12 around the through slot 11 prevent rainwater from entering through the through slot 11 and protect the electrical performance. At the same time, the inclined plate 13 blocks rainwater from flowing to the connection between the support plate 41 and the base 3, further enhancing the waterproof effect and providing all-round protection for the main body 1 of the power transformer, thus extending its service life.

[0031] 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.
