Description

Technical Field

[0001] This utility model relates to the technical field of transformers, and in particular to a quick-maintenance double-split dry-type transformer connection device. Background Technology

[0002] In power system distribution engineering, dry-type transformers are key power conversion equipment. When a double-split dry-type transformer is operating normally, power transmission only occurs between the high-voltage winding and the low-voltage winding. Since the low-voltage winding is split into two independent windings, they can operate independently or in parallel to supply power to different loads. When the load or power supply connected to one of the low-voltage windings fails, the remaining low-voltage windings can still operate normally.

[0003] In existing technologies, the transformer body is usually connected to the foundation embedded parts by multiple independent anchor bolts. Due to the high precision requirements of the bolt hole positions, the transformer position needs to be repeatedly adjusted during installation to achieve alignment of the bolts and holes, which is not only time-consuming and labor-intensive, but also easily damages the equipment base. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-maintenance double-split dry-type transformer connection device with high disassembly and assembly efficiency and convenient operation.

[0005] This utility model discloses a quick-maintenance double-split dry-type transformer connection device, comprising: The transformer body has at least two mounting parts at the bottom. The bottom of the mounting parts is provided with V-shaped guides, and the two ends of the mounting parts are respectively provided with locking mechanisms. The mounting base is provided with a V-groove, and the guide component slides in the V-groove along the length direction. Both ends of the V-groove of the mounting base are provided with threaded holes along the length direction, and the locking mechanism is connected to the threaded holes. The locking mechanism includes: A piston cylinder is mounted on a mounting component, and a movable component is slidably mounted inside the piston cylinder. The threaded post is fixedly connected to the moving part, and the threaded post is connected to the threaded hole of the mounting base.

[0006] As a preferred embodiment of this utility model, the threaded hole is configured as a stepped hole, and the top of the threaded hole is an unthreaded inner hole with an inner diameter larger than the outer diameter of the threaded post.

[0007] As a preferred embodiment of this utility model, a spring is provided on the moving part, and the other end of the spring is connected to the inner wall of the piston cylinder.

[0008] As a preferred embodiment of this utility model, a locking element is provided on the threaded column, and the locking element is connected to the outer wall of the piston cylinder.

[0009] As a preferred embodiment of this utility model, a screw is provided in the threaded inner hole of the locking member, and the screw is connected to the groove hole reserved on the outer wall of the piston cylinder.

[0010] As a preferred embodiment of this utility model, one end of the threaded column is provided with a chamfered structure, and the other end is provided with a regular polygonal inner hole.

[0011] As a preferred embodiment of this utility model, a bolt is provided at the threaded hole of the mounting base, and the bolt is connected to the threaded post.

[0012] As a preferred embodiment of this utility model, the threaded column is provided with multiple inner grooves at equal angles along its length.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The V-shaped guide on the bottom mounting part of the transformer body cooperates with the V-shaped groove of the mounting base to quickly and initially position the transformer body during installation. Utilizing the self-centering characteristics of the V-shaped structure, it effectively avoids displacement of the transformer body during installation. At the same time, the V-shaped groove is a through groove to prevent the accumulation of debris, greatly reducing the difficulty of alignment. After positioning, the transformer body is moved along the length of the V-shaped groove, so that the threaded post of the locking mechanism is quickly and coaxially aligned with the threaded hole of the mounting base, simplifying the installation operation process. The piston cylinder of the locking mechanism is installed on the mounting part, providing stable sliding space for the moving part and preventing the threaded post from falling off. At the same time, it ensures that the threaded post retracts when it contacts the mounting base to prevent it from affecting the guide. After the threaded post and the threaded hole are coaxial, they cooperate and connect with the threaded hole, thus completing the firm fixation of the transformer body and the mounting base. This eliminates the complicated alignment adjustment process and realizes the rapid installation of the transformer body and convenient disassembly for later maintenance. Attached Figure Description

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figures 1 to 4 As shown, this embodiment provides a quick-maintenance double-split dry-type transformer connection device, including: The transformer body 1 has at least two mounting parts 2 at its bottom end. The bottom end of the mounting part 2 is provided with a V-shaped guide part 3, and the two ends of the mounting part 2 are respectively provided with locking mechanisms 4. Mounting base 5 is provided with a V-groove, which is a through groove. Guide 3 is slidably installed in the V-groove along its length. Threaded holes are provided at both ends of the V-groove along its length. Locking mechanism 4 is connected to the threaded holes. Locking mechanism 4 includes: Piston cylinder 41 is mounted on mounting part 2, and movable part 42 is slidably mounted inside piston cylinder 41; The threaded post 43 is fixedly connected to the movable part 42, and the threaded post 43 is connected to the threaded hole of the mounting base 5. In this embodiment, the V-shaped guide 3 on the bottom mounting part 2 of the transformer body 1 cooperates with the V-shaped groove of the mounting base 5 to quickly and initially position the transformer body 1 during installation. Utilizing the self-centering characteristic of the V-shaped structure, it effectively avoids displacement of the transformer body 1 during installation. At the same time, the V-shaped groove is a through groove to prevent the accumulation of debris, greatly reducing the difficulty of alignment. After positioning, the transformer body 1 is moved along the length of the V-shaped groove, so that the threaded post 43 of the locking mechanism 4 is quickly and coaxially aligned with the threaded hole of the mounting base 5, simplifying the installation operation process. The piston cylinder 41 of the locking mechanism 4 is installed on the mounting part 2, providing stable sliding space for the moving part 42 and preventing the threaded post 43 from falling off. At the same time, it ensures that the threaded post 43 retracts when it contacts the mounting base 5 to prevent it from affecting the guide 3. After the threaded post 43 is coaxial with the threaded hole, it is connected with the threaded hole, thus completing the firm fixation of the transformer body 1 and the mounting base 5. This eliminates the complicated alignment adjustment process and realizes the rapid installation of the transformer body 1 and convenient disassembly for later maintenance.

[0018] As a preferred embodiment of the above technical solution, such as Figures 1 to 4As shown, the threaded hole is set as a stepped hole, and the top of the threaded hole is an unthreaded inner hole with an inner diameter larger than the outer diameter of the threaded post 43. A spring 44 is provided on the moving part 42, and the other end of the spring 44 is connected to the inner wall of the piston cylinder 41; In this embodiment, the unthreaded inner hole with an inner diameter larger than the outer diameter of the threaded post 43 allows the threaded post 43 to fall into the threaded hole as it moves along the V-groove with the transformer body 1, locking the movement of the transformer body 1. The spring 44 on the moving part 42 pushes the moving part 42 to automatically slide the threaded post 43 towards the threaded hole, allowing the threaded post 43 to quickly fall into the threaded section of the threaded hole, thus achieving automatic docking between the threaded post 43 and the threaded hole. This further simplifies the installation operation, reduces manual alignment and adjustment steps, and shortens the installation time of the transformer body 1.

[0019] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, a locking element 45 is provided on the threaded column 43, and the locking element 45 is connected to the outer wall of the piston cylinder 41. A screw 46 is provided in the threaded inner hole of the locking member 45, and the screw 46 is connected to the groove hole reserved on the outer wall of the piston cylinder 41. In this embodiment, the locking member 45 is connected to the outer wall of the piston cylinder 41. After the threaded column 43 is locked in place with the threaded hole of the mounting base 5, the locking member 45 further abuts against the outer wall of the piston cylinder 41 to enhance the fixing effect of the threaded column 43 and improve the overall stability of the connection. The screw 46 provided in the threaded inner hole of the locking member 45 is connected to the groove hole reserved on the outer wall of the piston cylinder 41. After the locking member 45 abuts against the piston cylinder 41, the locking member 45 is positioned by the engagement of the screw 46 with the groove hole, preventing the locking member 45 from rotating and loosening, forming a double locking structure. This strengthens the connection reliability between the threaded column 43 and the mounting base 5, prevents the risk of loosening during long-term use, and does not affect the quick docking during installation and convenient disassembly during maintenance.

[0020] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the threaded post 43 has a chamfered structure at one end and a regular polygonal inner hole at the other end. In this embodiment, the chamfered structure at one end of the threaded post 43 guides the threaded post 43 to smoothly slide into the unthreaded inner hole at the top of the threaded hole and the subsequent threaded section when the threaded post 43 is pushed by the spring force of the spring 44 towards the threaded hole of the mounting base 5. This ensures that the threaded post 43 and the threaded hole can quickly and accurately fit together, further improving installation efficiency. The regular polygonal inner hole at the other end of the threaded post 43 provides a standardized force application interface for rotating the threaded post 43. Workers can use a suitable tool to insert into the regular polygonal inner hole and easily rotate the threaded post 43 to tighten or loosen it from the threaded hole.

[0021] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, a bolt 6 is provided at the threaded hole of the mounting base 5, and the bolt 6 is connected to the threaded post 43. The threaded column 43 has multiple inner grooves at equal angles along its length. In this embodiment, the bolt 6 is connected to the threaded post 43. Based on the initial engagement between the threaded post 43 and the threaded hole of the mounting base 5, a double threaded locking structure of threaded post 43-threaded hole and bolt 6-threaded post 43 is formed, which strengthens the connection strength between the transformer body 1 and the mounting base 5 and effectively resists the vibration generated during transformer operation. Multiple inner grooves are set at equal angles along the length direction of the threaded post 43 to increase the connection strength between the bolt 6 and the threaded post 43.

[0022] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
