Description

Technical Field

[0001] This utility model relates to the field of low-voltage transformer technology, specifically to a low-voltage transformer capable of automatic voltage transformation. Background Technology

[0002] In low-voltage electrical systems, low-voltage transformers below 600V serve as core devices for voltage transformation, current transformation, impedance matching, and safety isolation, and are widely used in industrial control, power distribution, communication equipment, and consumer electronics. They achieve voltage rise and fall through the principle of electromagnetic induction, utilizing the turns ratio of the primary and secondary coils, and can achieve voltage stabilization through special designs such as magnetic saturation. With the rapid development of power electronics technology, low-voltage transformers are gradually evolving towards higher integration, multi-functionality, and intelligence. In particular, the introduction of automatic voltage regulation further enhances their adaptability to load fluctuation scenarios.

[0003] In practical applications of low-voltage transformers, especially in scenarios with a large number of connecting wires, the existing technology still has the following technical problems that urgently need to be solved: a large number of input / output wires (such as power lines, control lines, grounding wires, etc.) are usually connected inside the low-voltage transformer cabinet. Traditional designs lack effective wire guiding and fixing mechanisms, resulting in wires crossing and tangling randomly inside the cabinet.

[0004] Not only does the arrangement of wires affect the aesthetics of the equipment, but a messy wire layout also increases the difficulty of equipment maintenance and troubleshooting, and prolongs downtime. Furthermore, the path of the wires in the cabinet is usually simply constrained by fixed brackets or cable ties, making it impossible to flexibly adjust the bending angle according to actual needs. Once the wires are subjected to excessive stress due to excessive bending (exceeding the minimum bending radius) near the fixed point, it is easy to cause the insulation layer to crack or the conductor to break. Utility Model Content

[0005] The purpose of this utility model is to provide a low-voltage transformer that can automatically change voltage, so as to solve the technical problems mentioned in the background art, which are that the layout of the wires in the cabinet increases the maintenance cost and that the wires cannot be flexibly fixed in the cabinet.

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

[0007] A low-voltage transformer with automatic voltage transformation includes a cabinet, side panels, and a compression assembly; the transformer body is installed inside the cabinet, and several wires are connected to the bottom of the transformer body; the side panels are fixed to the bottom wall of the cabinet by two support legs, and several first guide slots adapted to the wires are provided on one side of the side panels, and several wires are respectively inserted into several first guide slots; a guide plate is provided at the bottom of the side panels, and the guide plate is rotatably connected to the two support legs by a rotating shaft.

[0008] The extrusion assembly includes an extrusion plate. A guide rod and a mounting block are fixedly connected to the side of the extrusion plate near the side plate. The guide rod is movably sleeved with the side plate. A first bolt is threaded to one side of the mounting block. The end of the first bolt is rotatably connected to the outer wall of the side plate. A pushing assembly is provided at the bottom of the side plate to push the side plate to rotate around the axis.

[0009] As a preferred embodiment of this utility model, the pushing component includes a fixed block, which is fixed between two legs. A second bolt is threadedly connected to the center of the fixed block, and a push block is rotatably connected to the end of the second bolt. A connecting plate is fixedly connected to the side of the push block near the fixed block, and the connecting plate is movably sleeved with the fixed block.

[0010] As a preferred embodiment of this utility model, the guide plate is set in an inclined state, and the upper end of the guide plate is provided with a plurality of second guide grooves corresponding to the first guide groove.

[0011] As a preferred embodiment of this utility model, a rubber pad is fixedly connected to the side of the extrusion plate near the side plate, and the rubber pad corresponds to a number of first guide grooves.

[0012] As a further preferred embodiment of this utility model, the push block cross section is set to a right-angled trapezoid shape, and the inclined surface of the push block is in contact with the bottom end of the guide plate.

[0013] As a further preferred embodiment of this utility model, the horizontal height of the top of the push block is less than the horizontal height of the rotating shaft.

[0014] Compared with the prior art, the low-voltage transformer with automatic voltage transformation provided by this utility model has the following beneficial effects:

[0026] See Figure 1-5As shown, the low-voltage transformer with automatic voltage transformation according to this utility model embodiment includes a cabinet 1, a side plate 4, and an extrusion assembly 7; a transformer body 2 is installed inside the cabinet 1, and a plurality of wires 3 are connected to the bottom end of the transformer body 2; the side plate 4 is fixed to the bottom wall of the cabinet 1 by two support legs 5, and a plurality of first guide grooves 9 adapted to the wires 3 are provided on one side of the side plate 4, and the plurality of wires 3 are respectively inserted into the plurality of first guide grooves 9; a guide plate 6 is provided at the bottom end of the side plate 4, and the guide plate 6 is rotatably connected to the two support legs 5 by a rotating shaft 11; the extrusion assembly 7 includes an extrusion plate 71, and a guide rod 72 and a mounting block are fixedly connected to the side of the extrusion plate 71 near the side plate 4. 73. The guide rod 72 is movably sleeved with the side plate 4. The mounting block 73 is threaded with a first bolt 74 on one side. The rod end of the first bolt 74 is rotatably connected to the outer wall of the side plate 4. The bottom end of the side plate 4 is provided with a pushing assembly 8 that pushes the side plate 4 to rotate around the rotating shaft 11. The first guide groove 9 on the side plate 4 cooperates with the second guide groove 10 on the guide plate 6 to fix the multiple wires 3 of the transformer body 2 according to the path, so as to avoid the wires 3 crossing and tangling in the cabinet 1. Then, by adjusting the position of the push block 81 by the second bolt 84 of the pushing assembly 8, the tilt angle of the guide plate 6 can be dynamically changed, thereby adapting to the optimal bending path of the wires 3 under different working conditions.

[0027] The guide plate 6 is set in an inclined state. The upper end of the guide plate 6 is provided with several second guide grooves 10 corresponding to the first guide groove 9. By cooperating with the first guide groove 9 on the side plate 4 and the second guide grooves 10 on the guide plate 6, the multiple wires 3 of the transformer body 2 are fixed in sections according to the path, so as to avoid the wires 3 from crossing and tangling in the cabinet 1.

[0028] A rubber pad 75 is fixedly connected to the side of the extrusion plate 71 near the side plate 4. The rubber pad 75 corresponds to several first guide grooves 9. The rubber pad 75 protects the wire 3 and prevents the extrusion plate 71 from extruding and damaging the wire 3.

[0029] In use, the voltage on the primary and secondary sides of the transformer is proportional to the number of turns. By changing the number of turns in the winding, the output voltage can be changed. When the load changes and causes voltage fluctuations, the transformer adjusts the number of turns in the winding through the built-in tap changer or automatic management terminal to stabilize the output voltage and thus activate the automatic voltage regulation function. The conductor 3 at the bottom of the transformer is fixed in sections according to the path through the first guide groove 9 and the second guide groove 10 to avoid the conductor 3 from crossing and tangling in the cabinet 1. The systematic arrangement of the conductor 3 also reduces the time spent sorting out the path of the conductor 3 during manual maintenance. Furthermore, by rotating the first bolt 74, the first bolt 74 drives the pressing plate 71 to move. When the pressing plate 71 moves closer to the side plate 4, it will press and clamp the conductor 3 in the first guide groove 9, thereby ensuring the stability of the conductor 3.

[0030] The bottom end of the guide plate 6 is also provided with a pushing component 8, which includes a fixing block 82. The fixing block 82 is fixed between two support legs 5. A second bolt 84 is threadedly connected to the center of the fixing block 82. A push block 81 is rotatably connected to the end of the second bolt 84. A connecting plate 83 is fixedly connected to the side of the push block 81 near the fixing block 82. The connecting plate 83 is movably sleeved with the fixing block 82. The tilt angle of the guide plate 6 can be freely adjusted by the push block 81, so as to adapt to the optimal bending path of the conductor 3 under different working conditions and ensure the safety of the conductor 3.

[0031] The push block 81 has a right-angled trapezoidal cross section. The inclined surface of the push block 81 is in contact with the bottom of the guide plate 6, and the horizontal height of the top of the push block 81 is less than the horizontal height of the rotating shaft 11, so as to ensure that the push block 81 will push the guide plate 6 to flip synchronously when it moves laterally.

[0032] In use, rotating the second bolt 84 causes the push block 81 to move laterally. Since the push block 81 has a right-angled trapezoidal cross-section and its inclined surface is in contact with the bottom of the inclined guide plate 6, the push block 81 will push the guide plate 6 synchronously during stable lateral movement, causing the guide plate 6 to rotate around the pivot 11. This can dynamically change the tilt angle of the guide plate 6, thereby adapting to the optimal bending path of the conductor 3 under different working conditions and ensuring the safety and service life of the conductor 3.

[0033] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
