Description

Technical Field

[0001] This utility model relates to the field of transformer core technology, and in particular to the core of a seven-column three-phase voltage stabilizer transformer. Background Technology

[0002] Three-phase transformers are mainly used for voltage level transformation in power systems, therefore they have relatively large capacities and high voltages. A three-phase transformer can be constructed from single-phase transformers of the same capacity, or it can be implemented by winding corresponding input and output coils on three iron core columns. Publication number CN204270817U discloses a seven-column three-phase voltage stabilizing transformer core, comprising columns made of several types of iron chips stacked together and fixed through fixing holes on the iron chips. The transformer core is characterized by... It includes a main magnetic circuit consisting of a set of three core pillars, a front core pillar, and a rear core pillar, and a secondary magnetic circuit consisting of a first secondary core pillar, a second secondary core pillar, a third secondary core pillar, and a fourth secondary core pillar. In the secondary magnetic circuit, the first and fourth secondary core pillars on both sides are made of U-shaped iron chip VI stacked in multiple layers, while the second and third secondary core pillars in the middle are made of L-shaped iron chip V stacked in multiple layers. The second secondary core pillar is an inverted L-shaped core pillar, and the third secondary core pillar is a regular L-shaped core pillar. There is a gap between the core pillars of the main magnetic circuit and the secondary magnetic circuit. This invention features a more rational leakage flux circuit with lower energy consumption, resulting in energy savings and improved efficiency for the voltage regulator. Furthermore, the complementary magnetic flux between each core contributes to a more balanced three-phase output. However, while this product offers advantages such as a more rational leakage flux circuit, lower energy consumption, energy savings, and improved efficiency, the core module is inconvenient to disassemble for maintenance, reducing disassembly and maintenance efficiency. Additionally, damage to a single core necessitates replacement, increasing replacement costs and reducing core lifespan. Therefore, its practicality is limited and improvements are needed.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-5This utility model provides a technical solution: a seven-column three-phase voltage stabilizer transformer core, including a base 1, a core A2, and a core B3. A sliding plate 4 is fixedly installed on the lower surface of core A2 to lock and fix core A2. A slide rail 5 is fixedly installed at the bottom end of the sliding plate 4. A ball bearing 6 is rotatably connected to the lower surface of the slide rail 5 to facilitate smoother movement of the sliding plate 4. A connecting rod 7 is slidably connected inside the sliding plate 4 to lock the sliding plate 4 on the base 1. A pull head 8 is fixedly installed at the top of the connecting rod 7 for easy pulling. A tension spring 9 is fixedly installed on the lower surface of the pull head 8 to automatically return the connecting rod 7 to its original position. A handle 10 is fixedly installed on the upper surface of the sliding plate 4 for easy pulling. A slider 11 is fixedly installed on the lower surface of core B3 to move core B3. The base 1 has a sliding connection to a limit rod 12, which locks and limits the slider 11. A push plate 13 is fixedly installed at one end of the limit rod 12 to facilitate pulling the limit rod 12. A spring 14 is fixedly installed on the side of the push plate 13 to allow the limit rod 12 to automatically return to its original position. The sliding plate 4 and the slide rail 5 are slidably connected to the base 1. The ball bearing 6 is rotatably connected to the base 1 to keep the sliding plate 4 stable when it slides out of the base 1. The connecting rod 7 is slidably connected to the base 1. One end of the tension spring 9 is fixedly connected to the sliding plate 4, allowing the connecting rod 7 to automatically slide from the inside of the sliding plate 4 to the inside of the base 1. The limit rod 12 is slidably connected to the slider 11. One end of the spring 14 is fixedly connected to the base 1, allowing the limit rod 12 to automatically slide from the inside of the base 1 to the inside of the slider 11.

[0024] Example 2

[0025] Please see Figure 1-5 A mounting bracket 15 is fixedly installed on the side of the base 1, so that the fixing bracket 16 and the lead screw 17 can be installed. The fixing bracket 16 is fixedly installed on the side of the mounting bracket 15, so that the mounting brackets 15 are connected to each other to maintain stability. The lead screw 17 is connected to the internal thread of the mounting bracket 15, so that the mounting brackets 15 are connected to each other. The nut 18 is connected to the surface thread of the lead screw 17, so that the mounting bracket 15 can be installed on the lead screw 17. There are four sets of mounting brackets 15. The fixing bracket 16 is located on one side of the two sets of mounting brackets 15 near the top of the lead screw 17 to ensure the overall stability.

[0026] Working principle: First, when replacing iron core A2, grasp the pull head 8 and pull it, causing the pull head 8 to drive the connecting rod 7 to slide inside the sliding plate 4 and the base 1. When the connecting rod 7 slides from inside the base 1 to inside the sliding plate 4, grasp the handle 10 and pull it, causing the handle 10 to drive the sliding plate 4 to slide on the upper surface of the base 1. At the same time, the guide rail slides inside the base 1, and the ball bearing 6 rotates inside the base 1, thus smoothly removing iron core A2. After installing, maintaining, or replacing iron core A2, align the sliding plate 4 with the position of the base 1 and push it. When the sliding plate 4 slides to the appropriate position, the tension spring 9 can drive the connecting rod 7 to move, causing the connecting rod 7 to slide from inside the sliding plate 4 to inside the base 1, thereby locking and fixing the sliding plate 4. When disassembling iron core B3, first grasp the push plate 13 and pull it, causing the push plate 13 to drive the limit rod 12. The slider 11 slides inside the base 1 and the slide block 11. When the limiting rod 12 slides out from the inside of the slide block 11, the slider 11 can be pulled by grasping the slide block 11 and the iron core B3 to make the slide block 11 slide out from the inside of the base 1. After the iron core B3 is installed, the slide block 11 is first pushed to the position of the base 1. When the slide block 11 moves to the appropriate position, the spring 14 can drive the push plate 13 and the limiting rod 12 to move, so that the limiting rod 12 slides from the inside of the base 1 to the inside of the slide block 11, thereby locking and fixing the slide block 11. Then, the mounting bracket 15 is fixed to the appropriate position on the base 1. Then, the screw 17 is rotated to the inside of the four sets of mounting brackets 15, thereby strengthening the whole through the fixing bracket 16. Finally, the nut 18 is aligned with the position of the screw 17 and rotated. The screw 17 is rotated through the thread between the nut 18 and the screw 17, thereby making the screw 17 and the mounting bracket 15 stably reinforced.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
