[0002] In power transmission and distribution systems, transformers are key equipment, and their performance and reliability play a crucial role in the stable operation of the entire system. With the development of electrical engineering technology, transformer design has continuously improved, evolving from simple structures to today's complex and efficient electromagnetic conversion devices. Among these components, the magnetic core, as one of the core components of the transformer, has its material selection, shape design, and installation method directly affecting the transformer's operating efficiency, size, and cost control.

[0003] Although existing transformer cores have adopted a modular design concept to facilitate production and assembly, some shortcomings still exist.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Note: In the translation of item , the description of the "几" - shaped structure is translated as "U" - shaped structure for better understanding in English. In Chinese, "几" - shaped structure is similar to a "U" - shaped structure in appearance. If there is a more specific or accurate English term for this structure in the context of transformer components, it can be adjusted accordingly.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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a transformer core assembly device, including a support base 1. The top surface of the support base 1 has several core modules 2 arranged in parallel. End plates are fixed to both the upper and lower ends of each core module 2. Vertically distributed positioning guide posts 3 are provided on both sides of the top wall of the support base 1. Horizontally distributed limiting crossbeams 4 connect the positioning guide posts 3. The limiting crossbeams 4 have several through holes that match the structure of the core modules 2. Positioning sleeves 5 are fitted and fixed to both sides of the through holes on the limiting crossbeams 4. Locking screws are connected to the positioning sleeves 5 via a threaded structure. Positioning shafts 6 are inserted inside the positioning sleeves 5. The top of each group of positioning shafts 6 is connected to an elastic pressure block 7 that presses against the top end plate of the core module 2. This structure... The guide post 3 works in conjunction with the limiting crossbeam 4 to provide a stable frame structure for the entire device, ensuring the precise positioning of the magnetic core module 2 on the support base 1. Specifically, when installing the magnetic core module 2, the operator can align the end plates fixed at both ends of the magnetic core module 2 with the through holes on the limiting crossbeam 4, and allow the positioning shaft 6 to pass through the positioning sleeve 5. Initial fixation is achieved using the locking screws on the positioning sleeve 5. At this point, the elastic pressure block 7 connected to the top of the positioning shaft 6 automatically adapts to the shape of the top end plate of the magnetic core module 2 and applies a certain pressure, allowing the magnetic core module 2 to be quickly and accurately positioned and securely connected to the support base 1. This design not only simplifies the assembly process but also allows workers to achieve this without the use of additional tools, relying on the elastic... The elasticity of the pressure block 7 enables rapid pre-fixation, followed by final fixing with locking screws, greatly improving installation efficiency. This solves the problems of cumbersome assembly, adjustment, and maintenance difficulties in the existing transformer core assembly process. Due to the adoption of rapid positioning and flexible fixing methods, assembly time and labor costs are reduced, and subsequent adjustments and maintenance are facilitated, lowering maintenance costs while also improving the product's applicability and reliability. The top of the positioning shaft 6 has a bent section, and an elastic support 8 connects the bottom of the bent section at the top of the positioning shaft 6 to the top of the elastic pressure block 7. The elastic support 8 is a U-shaped elastic metal material. This structure allows the elastic pressure block to... The positioning shaft 6 and the elastic support 8 work together to apply a downward pressure to the core module 2, ensuring it is securely placed on the support base 1. This achieves rapid and precise positioning of the core assembly, while ensuring the stability of the connection and the system's vibration resistance, greatly improving the efficiency and safety of the transformer assembly process. Elastic washers 11 are bonded and fixed to the inner wall of the perforations on the limiting crossbeam 4. The inner wall of the elastic washer 11 has a wavy structure. When the positioning shaft 6 passes through these perforations to install the core module 2, the wavy elastic washer 11 will make close contact with the surface of the positioning shaft 6 and produce slight deformation. This provides additional friction between the parts, ensuring that the positioning shaft 6 can be securely held in the required position.To prevent unnecessary movement or shaking during installation or operation, the wavy inner wall of the elastic washer 11 provides a certain buffering effect when the positioning shaft 6 is inserted and pulled out, reducing hard collisions between the two and protecting the positioning shaft 6 and the limiting crossbeam 4 from damage. Positioning rings 9, sleeved on the outside of the positioning guide post 3, are welded and fixed to both sides of the limiting crossbeam 4. A locking nut 10 is threadedly connected to the bottom of the connection between the positioning ring 9 and the positioning guide post 3. Based on the specific dimensions and installation requirements of the magnetic core module 2, the operator first slides the positioning ring 9 up and down, causing the limiting crossbeam 4 to move along the positioning guide post 3. Until the correct height is reached, once the appropriate position is determined, the locking nut 10 is tightened to securely fix the positioning ring 9 using its threaded structure. This ensures that the limiting crossbeam 4 is stably locked at the set height. This not only achieves precise adjustment of the height of the limiting crossbeam 4 but also ensures its stability during installation, preventing any accidental displacement. This simplifies the assembly process, improves installation accuracy and efficiency, and allows the transformer core assembly device to flexibly adapt to different specifications of core modules 2. The elastic pressure block 7 has a rectangular strip structure, and a rubber pad is glued and fixed to the bottom of the elastic pressure block 7. This structure is used when the core... After module 2 is installed in place, the positioning shaft 6 drives the elastic pressure block 7 to move downwards, causing the rubber pad to make tight contact with and apply pressure to the end plate on the top of the magnetic core module 2. The rectangular strip structure of the elastic pressure block 7 ensures that the pressure is evenly distributed across the entire contact surface, avoiding damage that may be caused by uneven local force. The presence of the rubber pad not only increases friction and prevents the magnetic core module 2 from shifting during operation, but also acts as a buffer, absorbing external vibrations and impacts, and protecting the magnetic core module 2 from mechanical damage. The support base 1 has an overall "U"-shaped structure, and several mounting holes are provided on both sides of the support base 1. Heat dissipation holes are provided at the connection points between the middle of the support frame 1 and the bottom of the magnetic core module 2. This structure provides strong mechanical support and stability, ensuring that the entire device can withstand various forces generated during operation. The mounting holes on both sides of the support frame 1 allow the device to be securely fixed to designated positions using bolts or other fasteners, enhancing the overall structural stability and facilitating installation and disassembly. The heat dissipation holes at the connection points between the middle of the support frame 1 and the bottom of the magnetic core module 2 promote airflow, effectively dissipating the heat generated by the magnetic core module 2, preventing overheating, and ensuring the working efficiency and lifespan of the magnetic core module 2.

[0018] Working principle: When assembling the magnetic core device using this transformer, firstly, according to the specific dimensions and installation requirements of the magnetic core module 2, the operator slides the positioning rings 9 on both sides of the limiting crossbeam 4 up and down, and moves the limiting crossbeam 4 to a suitable height position along the positioning guide post 3. Once the ideal height is reached, the locking nut 10 is tightened, and the positioning ring 9 is firmly fixed by the threaded structure at the bottom of its connection with the positioning guide post 3, ensuring that the limiting crossbeam 4 is stably locked at the set height. Next, the end plates fixed at the upper and lower ends of the magnetic core module 2 are aligned with the through holes on the limiting crossbeam 4. At this time, the elastic washer 11 will make close contact with the surface of the positioning shaft 6 and produce slight deformation, providing additional friction to ensure that the positioning shaft 6 is firmly held in the required position. Then, the positioning shaft 6 is passed through the positioning sleeve 5 and fixed by the locking screw on the positioning sleeve 5. The elastic pressure block 7 connected to the top of the positioning shaft 6 will automatically adapt to the shape of the top end plate of the magnetic core module 2 and apply a certain pressure under the elastic force of the elastic support 8, so that several magnetic core modules 2 can be quickly and accurately positioned and firmly connected to the support base 1, thereby completing a series of tasks.
