[0002] Voltage transformers are key devices used for voltage transformation and measurement in power systems. Their function is to convert high voltage to low voltage proportionally through the principle of electromagnetic induction, so that it can be used by instruments, relays and protection devices. They can isolate high voltage circuits and ensure the safety of personnel and equipment. However, when installing voltage transformers, the installation structure is not the same in different locations in the power system, and the mounting holes of the voltage transformer itself are difficult to match, making installation difficult.

[0003] According to application number 202323228935.9, a voltage transformer that is easy to assemble and disassemble includes a base, a housing assembly fixedly mounted on the top of the base, a functional component fixedly mounted on the top of the housing assembly, a protective cover fixedly mounted on the top of the functional component, and two symmetrical sliding grooves opened on both sides of the base. A threaded rod is rotatably arranged inside each of the two sliding grooves. A slider is threadedly connected to the outer side of the threaded rod. A mounting block is fixedly connected to the side wall of the slider, and a mounting hole is opened on the mounting block.

[0004] The aforementioned document describes a device that uses a slide, threaded rod, slider, and drive assembly to enable the drive assembly to rotate the threaded rod. The threaded rod can then push the slider and mounting block to adjust their positions, making the device easy to assemble and disassemble. However, it lacks the ability to adjust the installation angle and cannot install voltage transformers on uneven surfaces. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an assembly-type voltage transformer that is easy to assemble and disassemble, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-assemble and disassemble prefabricated voltage transformer includes a transformer body, an external mounting frame, two extension frames rotatably mounted on the bottom sides of the mounting frame, limiting components on both sides of the transformer body, a snap-fit ​​component on the back of the transformer body, two adjustment slots on each side of the external mounting frame, two storage slots at the top ends of the extension frames, a connecting rod hinged inside the storage slots, and a bolt plate slidably mounted in the middle of the extension frames, with an adjustment component passing through the middle of the bolt plate.

[0008] Preferably, the limiting component includes multiple limiting strips welded to both sides of the main shell of the current transformer, and multiple limiting grooves for inserting the limiting strips are opened on both sides inside the mounting frame, and an interface frame is opened through one end of the mounting frame.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] Please refer to the attached document carefully. Figure 1 , 2As shown in Figure 4, a modular voltage transformer that is easy to assemble and disassemble includes a transformer body 19. A mounting frame 10 is fitted around the transformer body 19. Two extension frames 11 are rotatably mounted on the bottom sides of the mounting frame 10. Limiting components 12 are provided on both sides of the transformer body 19. A snap-fit ​​component 13 is provided on the back of the transformer body 19. Two adjustment slots 14 are provided on each of the outer sides of the mounting frame 10. Two storage slots 15 are provided at both ends of the top of the extension frames 11. A connecting rod 16 is hinged inside the storage slots 15. A bolt plate 17 is slidably mounted in the middle of the extension frame 11. An adjustment component 18 is provided through the middle of the bolt plate 17. Multiple equally spaced positioning holes 151 are vertically provided at both ends inside the adjustment slots 14. Guide post slots 152 are provided at both ends of the storage slots 15 away from the adjustment slots 14. A guide post slot 152 is provided near the adjustment slots 14. The side has an inclined notch; the end of the connecting rod 16 near the adjusting groove 14 is hinged inside the receiving groove 15, and the two sides of the end of the connecting rod 16 away from the adjusting groove 14 are concave. A metal guide post 161 is provided through each side of one end of the connecting rod 16, and the two metal guide posts 161 are connected by a third spring 162. A pressing post 163 is provided through each concave part of the connecting rod 16, and the pressing post 163 is fixedly connected to the inner end of the metal guide post 161 by a connecting rod 164; the adjusting component 18 includes two sliding grooves 181 opened on both sides inside the extension frame 11, and a threaded cylinder 182 is provided through the middle of both ends of the bolt plate 17. A threaded rod 183 is rotatably installed at both ends of the extension frame 11 and threadedly connected to the middle of the threaded cylinder 182. A knob 184 is provided at one end of the extension frame 11, and the knob 184 is fixedly connected to one end of the threaded rod 183.

[0025] As described above, before installing the transformer body 19, the external frame needs to be installed in the designated position. The flip angle of the two extension brackets 11 is determined according to the angle of the required installation position. The extension brackets 11 on both sides of the mounting frame 10 can be rotated outward through the bottom pivot, and after unfolding, they are aligned with the external mounting structure. Under normal circumstances, the metal guide posts 161 at both ends of the connecting rod 16 pop outward under the action of the third spring 162, and the metal guide posts 161 are stored in the guide post groove 152. When it is necessary to adjust the installation spacing, pull the connecting rod 16 outward to disengage its connecting end from the storage groove 15. By pressing the pressing post 163 to compress the third spring 162, the metal guide posts 161 can be retracted. Find a suitable positioning hole 151 to release the metal guide posts 161. The mounting frame 10 and extension frame 11 can be fixedly connected to prevent the extension frame 11 from rotating, thus adapting to different installation angles. When disassembly is required, the pressing column 163 can be pressed again to compress the third spring 162, which can cause the metal guide column 161 to retract and disengage from the positioning hole 151, and the extension frame 11 can be reassembled. The bolt plate 17 slides into the sliding groove 181 on both sides. The threaded rod 183 has a self-locking structure at both ends, which cannot be reversed by the threaded cylinder. After the angle adjustment is completed, the external knob 184 is turned to drive the threaded rod 183 to rotate. The threaded cylinder drives the bolt plate 17 to adjust its position along the sliding groove 181, so that the mounting hole on the bolt plate 17 is precisely aligned with the external structure. After being fixed with bolts, the installation stability of the entire device can be ensured.

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 3, the limiting component 12 includes multiple limiting strips 121 welded to both sides of the outer shell of the transformer body 19. Multiple limiting slots 122 for inserting the limiting strips 121 are opened on both sides inside the mounting frame 10. An interface frame 123 is opened through one end of the mounting frame 10. The snap-fit ​​component 13 includes a first rectangular groove 131 opened on the back of the outer shell of the transformer body 19. A trapezoidal plate 132 is slidably arranged inside the first rectangular groove 131. One end of the trapezoidal plate 132 is connected to the inner wall of the first rectangular groove 131 by multiple first springs 133. The snap-fit ​​component 13 also includes a second rectangular groove 134 opened at one end inside the mounting frame 10. A pressure plate 135 is movably arranged inside the second rectangular groove 134. A button 136 that passes through the mounting frame 10 is provided at one end of the middle of the pressure plate 135. One end of the pressure plate 135 is connected to the inner wall of the second rectangular groove 134 by a second spring 137.

[0027] As described above, after the external frame is installed, the limiting strips 121 on both sides of the transformer body 19 can be precisely inserted into the limiting grooves 122 inside the mounting frame 10 to form a preliminary positioning, ensuring that the axis of the main body is aligned with the central axis of the mounting frame 10. When the transformer body 19 is inserted into the mounting frame 10, the trapezoidal plate 132 in the first rectangular groove 131 on the back is squeezed by the inner wall of the mounting frame 10, compressing the first spring 133 and sliding inward; the second spring 137 is a short spring, used as a pressure plate 135 to retract into the second rectangular groove 134, and will not push the pressure plate 135 outward from the second rectangular groove 134. With the inclined surface facing down, after the main body is in place, the trapezoidal plate 132 aligns with the second rectangular groove 134 inside the mounting frame 10. Under the push of the first spring 133, the trapezoidal plate 132 is embedded into the second rectangular groove 134, completing the snap-fit ​​and preventing the transformer body 19 from falling off. After installation, the interface frame 123 at one end of the mounting frame 10 provides a channel for external wiring. If it is necessary to disassemble the transformer body 19, press the button 136 that passes through the mounting frame 10 to move the pressure plate 135 outward, push the trapezoidal plate 132 out of the second rectangular groove 134, release the snap-fit ​​on the transformer body 19, and the transformer body 19 can be easily removed.

[0028] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
