Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a voltage regulating transformer. Background Technology

[0002] Traditional power systems used to rely on fixed-tap transformers or manual voltage regulating devices to deal with voltage problems. However, fixed-tap transformers can only achieve segmented voltage regulation and cannot adapt to dynamic voltage changes in real time. At the same time, with the large-scale grid connection of new energy power generation, the intermittency of its output power has further aggravated grid voltage fluctuations, and the limitations of traditional voltage regulation methods have become increasingly prominent.

[0003] Against this backdrop, voltage regulating transformers, as core equipment capable of real-time and precise voltage regulation, have emerged. Through their built-in voltage regulating mechanism, they can automatically or manually adjust the turns ratio according to changes in grid voltage, stabilizing the output voltage within the standard range, thus solving the problems of voltage loss and fluctuation in power transmission and distribution.

[0004] However, existing voltage-regulating transformers mostly use a rigid connection design between the core components such as the iron core and windings and the shell, lacking an effective buffer absorption structure. The electromagnetic vibration generated during transformer operation is directly transmitted to the internal components. At the same time, the mechanical impact of the external environment can also be easily transmitted to the core components through the shell. This not only easily causes fatigue of the internal component structure and shortens the service life, but may also generate operating noise due to vibration transmission, and even cause loosening of component connections, affecting the overall operational stability of the transformer. To address this, we propose a voltage-regulating transformer. Summary of the Invention

[0005] One of the technical problems this application aims to solve is: how to design a voltage regulating transformer that is quick to install and disassemble, reduces sway, and is self-balancing.

[0006] To address the aforementioned technical problems, this application provides a voltage regulating transformer, including a housing, a cover plate, and a transformer device. The transformer device has two horizontal plates at its bottom, each with a groove at its bottom. Inside the housing, there are movably mounted locking seats that are movably connected to the two grooves. A locking and sliding mechanism is provided between the locking seats and the housing to quickly install the transformer device inside the housing while avoiding a rigid connection. Adjusting plates are located at the bottom of the two horizontal plates, and a rocking adjustment mechanism is provided between the adjusting plates and the bottom of the inner wall of the housing to quickly balance the shaking of the transformer device when it shakes, reducing damage to the transformer device.

[0007] In some embodiments, the snap-fit ​​transverse mechanism includes a drive plate disposed on the outside of the snap-fit ​​seat, an L-shaped rod disposed on the outside of the drive plate, a straight rod disposed inside the L-shaped rod, and a pressing plate disposed at both ends of the straight rod, with the tops of the two pressing plates respectively movably disposed at the bottom of the transverse plate.

[0008] In some embodiments, a support plate is provided at the bottom of the inner wall of the housing, a fixed inclined block is provided at the top of the support plate, and a movable inclined block is provided on the side of the snap-fit ​​seat. The inclined surfaces of the fixed inclined block and the movable inclined block are movably connected.

[0009] In some embodiments, a square shell is provided on the side of the card holder, a movable plate is movably disposed inside the square shell, a guide groove is provided on the outer side of the movable plate, and a guide block is provided inside the square shell that is movably connected to the guide groove.

[0010] In some embodiments, a light rod is provided at the bottom of the inner wall of the housing, the movable plate is movably sleeved on the outside of the light rod, a rubber disc is provided at the top of the light rod and movably connected to the movable plate, and a spring connected to the movable plate is sleeved on the outside of the light rod.

[0011] In some embodiments, the movable plate has two through slots inside, and the inner walls of the two through slots are movably embedded with balls, and the outer surfaces of the two balls are movably disposed on the outer surface of the guide rod.

[0012] In some embodiments, the shaking adjustment mechanism includes a base plate disposed at the bottom of the inner wall of the housing, an electromagnetic control rod disposed at each of the four corners of the base plate, a main control device disposed at the top of the base plate, and a connecting wire disposed between the main control device and the four electromagnetic control rods.

[0013] In some embodiments, a connecting cylinder is provided at the top of the electromagnetic control rod, an electromagnet first is provided at the top of the electromagnetic control rod, and an electromagnet second corresponding to the electromagnet first is movably disposed inside the connecting cylinder.

[0014] In some embodiments, the inner wall of the connecting cylinder is provided with an annular groove, and a movable rod connected to the second electromagnet is movably disposed on the inner wall of the annular groove. A tension spring connected to the second electromagnet is sleeved on the outer side of the movable rod.

[0015] In some embodiments, a connecting rod is provided through the connecting cylinder at the top end of the movable rod, a movable ball is provided at the top end of the connecting rod, and a connecting post connected to the bottom of the adjusting plate is movably provided on the outside of the movable ball.

[0016] This invention has at least the following beneficial effects:

[0017] 1. Through the dynamic cooperation of the L-shaped rod, the extrusion plate and the groove of the horizontal plate, and the coordinated operation of the rocking adjustment mechanism, a multi-level buffer system is built between the core components of the transformer and the shell. In terms of vibration isolation, when electromagnetic vibration is transmitted to the fixed inclined block through the card seat and the moving inclined block, the inclined structure converts the vertical vibration into horizontal displacement, and then the energy is efficiently absorbed by the spring and the rubber disc. In terms of impact dispersion, the rolling friction design of the ball and the smooth rod greatly reduces the risk of resonance, and the spring damping can effectively attenuate the external mechanical impact.

[0018] 2. The shaking adjustment mechanism uses the linkage between the electromagnetic control rod and the main control device to realize real-time correction of the transformer's attitude. When the transformer tilts due to sudden load changes or external disturbances, the repulsive force generated by the first and second electromagnetic disks pushes the movable rod, and the height of the connecting column is precisely adjusted through the tension spring, so that the adjustment plate can be quickly reset and achieve active balance.

[0019] 3. The snap-fit ​​transverse mechanism adopts modular quick-release, which greatly simplifies the installation and maintenance process. During the installation stage, when the transformer is lowered, the groove of the transverse plate and the snap-fit ​​seat can be automatically aligned. The drive plate triggers the pressing plate through the L-shaped rod to complete the locking, eliminating the need for traditional bolt fixing and thus increasing the efficiency of disassembly and assembly.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1-11 The present invention provides a technical solution: a voltage regulating transformer, including a housing 1, a cover plate 2 and a transformer device 3. The bottom of the transformer device 3 is provided with two horizontal plates 4, and the bottom of each of the two horizontal plates 4 is provided with a groove 9. The housing 1 is movably provided with a snap-fit ​​seat 5, which is movably connected to the two grooves 9 respectively. A snap-fit ​​transverse mechanism 6 is provided between the snap-fit ​​seat 5 and the housing 1, which is used to quickly install the transformer device 3 inside the housing 1 and avoid the rigid connection of the transformer device 3. The bottom of the two horizontal plates 4 is provided with an adjusting plate 7. A rocking adjustment mechanism 8 is provided between the adjusting plate 7 and the bottom of the inner wall of the housing 1, which is used to quickly balance the shaking of the transformer device 3 when it shakes, and reduce the damage to the transformer device 3.

[0034] The device consists of a housing 1, a cover plate 2, and a transformer 3. The housing 1 and the cover plate 2 form a closed protective space, which can isolate external dust and moisture from corroding the internal components. The transformer 3 is the core working component, with two horizontal plates 4 symmetrically fixed at its bottom. The grooves 9 at the bottom of the horizontal plates 4 and the snap-fit ​​seats 5 inside the housing 1 form a precise fitting structure, providing initial positioning for the transformer 3.

[0035] The snap-fit ​​transverse mechanism 6 includes a drive plate 63 disposed on the outside of the snap-fit ​​seat 5. An L-shaped rod 62 is disposed on the outside of the drive plate 63. A straight rod 64 is disposed inside the L-shaped rod 62. Both ends of the straight rod 64 are provided with pressing plates 61. The tops of the two pressing plates 61 are respectively movably disposed at the bottom of the transverse plate 4. The L-shaped rods on the outside of the drive plate 63 are distributed at right angles. The two ends of the straight rod 64 passing through it are respectively fixed to the two pressing plates 61, forming a linkage structure of the drive plate 63, the L-shaped rod, the straight rod 64 and the pressing plates 61.

[0036] A support plate 65 is provided at the bottom of the inner wall of the housing 1, and a fixed inclined block 66 is provided at the top of the support plate 65. A movable inclined block 67 is provided on the side of the snap-fit ​​seat 5. The inclined surfaces of the fixed inclined block 66 and the movable inclined block 67 are movably connected. The support plate 65 at the bottom of the inner wall of the housing 1 is made of high-strength alloy material and is fixed to the housing 1 by welding. The fixed inclined block 66 at the top of the support plate 65 and the inclined surface of the movable inclined block 67 on the side of the snap-fit ​​seat 5 are completely fitted together to form a wedge-shaped fit structure. This inclined surface can convert the vertical pressure when the transformer 3 is lowered into the horizontal displacement of the snap-fit ​​seat 5.

[0037] A square shell 610 is provided on the side of the card holder 5. A movable plate 612 is movably arranged inside the square shell 610. A guide groove 614 is provided on the outer side of the movable plate 612. A guide block 613 is provided inside the square shell 610 and is movably connected to the guide groove 614. The guide groove 614 on the outer side of the movable plate 612 is elongated and forms a sliding fit with the guide block 613 inside the square shell 610. The limiting effect of the guide block 613 on the guide groove 614 can restrict the movable plate 612 to move only in a preset direction, and prevent the movable plate 612 from deviating or getting stuck during the sliding process.

[0038] A light rod 68 is provided at the bottom of the inner wall of the housing 1. A movable plate 612 is movably sleeved on the outside of the light rod 68. A rubber disc 69 is provided at the top of the light rod 68 and is movably connected to the movable plate 612. A spring 611 connected to the movable plate 612 is sleeved on the outside of the light rod 68.

[0039] The smooth rod 68 at the bottom of the inner wall of the housing 1 is vertically fixed, and its surface is smoothed to reduce friction. The movable plate 612 is movably sleeved on the outside of the smooth rod 68 and can slide up and down along the smooth rod 68. The rubber disc 69 at the top of the smooth rod 68 is made of elastic material. When the movable plate 612 moves upward, the rubber disc 69 can play a buffering role. The two ends of the spring 611 on the outside of the smooth rod 68 are fixed to the bottom of the movable plate 612 and the bottom of the inner wall of the housing 1, respectively, and are in a pre-compressed state. When vibration occurs, the spring 611 can absorb vibration energy by stretching or compressing, reducing the impact of vibration on the transformer 3.

[0040] The movable plate 612 has two through slots 615 inside. The inner walls of the two through slots 615 are movably embedded with balls 616. The outer surfaces of the two balls 616 are movably disposed on the outer surface of the smooth rod 68. The outer surfaces of the balls 616 are in close contact with the surface of the smooth rod 68 to form a point contact sliding structure, which converts the sliding friction between the movable plate 612 and the smooth rod 68 into the rolling friction of the balls 616, greatly reducing the frictional resistance.

[0041] Example 2: Please refer to Figures 9-11 The present invention provides a technical solution: the shaking adjustment mechanism 8 includes a base plate 81 disposed at the bottom of the inner wall of the housing 1, an electromagnetic control rod 83 disposed at each of the four corners of the base plate 81, a main control device 84 disposed at the top of the base plate 81, and a connecting line 82 disposed between the main control device 84 and the four electromagnetic control rods 83.

[0042] The four electromagnetic control rods 83 are symmetrically distributed to ensure balanced support force on the adjustment plate 7. The main control device 84 at the top of the base plate 81 is the core control unit. The built-in attitude sensor can monitor the tilt angle of the transformer 3 in real time. The connection line 82 between the main control device 84 and the four electromagnetic control rods 83 is a shielded wire to avoid external electromagnetic interference affecting signal transmission. When the transformer 3 is detected to be shaking, the main control device 84 can quickly send a command to the corresponding electromagnetic control rod 83 through the connection line 82 to realize real-time response of attitude adjustment.

[0043] A connecting cylinder 88 is provided at the top of the electromagnetic control rod 83, and an electric disk first 810 is provided at the top of the electromagnetic control rod 83. An electric disk second 813 corresponding to the electric disk first 810 is movably arranged inside the connecting cylinder 88. When the electromagnetic control rod 83 is energized, the electric disk first 810 generates a magnetic field, which forms a repulsive or attractive force with the electric disk second 813. By changing the current, the interaction force between the two can be precisely adjusted, thereby driving the movement of subsequent components and providing a controllable power source for the balance adjustment of the transformer device 3.

[0044] The inner wall of the connecting cylinder 88 is provided with an annular groove 811. A movable rod 89 connected to the second electric disk 813 is movably disposed on the inner wall of the annular groove 811. A tension spring 812 connected to the second electric disk 813 is sleeved on the outer side of the movable rod 89. The limiting effect of the annular groove 811 on the movable rod 89 can prevent the second electric disk 813 from shifting horizontally during movement, ensuring that it only moves along the axial direction of the connecting cylinder 88. When the electromagnetic force disappears, the tension spring 812 pulls the second electric disk 813 to reset, so that the rocking adjustment mechanism 8 returns to its initial state, ensuring the reliability of the next adjustment.

[0045] A connecting rod 87 is provided at the top of the movable rod 89 through the connecting cylinder 88. A movable ball 86 is provided at the top of the connecting rod 87. A connecting column 85 connected to the bottom of the adjusting plate 7 is movably provided on the outside of the movable ball 86. This ball joint method allows the connecting column 85 to achieve three-dimensional angle fine adjustment around the movable ball 86. When the transformer 3 shakes in multiple directions, the adjusting plate 7 can flexibly adjust its posture and quickly balance the shaking through the cooperation of the connecting column 85 and the movable ball 86.

[0046] Working principle: When using this device, firstly, the transformer 3 is placed inside the housing 1 through the cover plate 2. At this time, the horizontal plate 4 will contact the extrusion plate 61 and extrude pressure on the extrusion plate 61. The extrusion plate 61 will drive the straight rod 64 on the side to move. The straight rod 64 will drive the L-shaped rod 62 on the outside to move. The L-shaped rod 62 will drive the drive plate 63 to move. At this time, the drive plate 63 will drive the locking seat 5 to descend. When the locking seat 5 moves, it will drive the moving inclined block 67 on the side to move. The moving inclined block 67 will press against the fixed inclined block 66. The fixed inclined block 66 is limited to the inner side of the housing 1 by the support plate 65. Therefore, the moving inclined block 67 will drive the locking seat 5 to move towards the inner wall of the housing 1 while descending. At this time, the locking seat 5 will drive the square shell 610 to move. The square shell 610 slides on the outer surface of the moving plate 612. At this time, the moving plate 612 will slide on the outer surface of the light rod 68 and will squeeze the spring 611, causing the spring 611 to deform. At this time, the locking seat 5 will enter the inner wall of the groove 9, thereby completing the limiting of the transformer 3 and quick disassembly and assembly.

[0047] When the transformer 3 shakes or tilts inside the housing 1, the main control device 84 receives a signal. The signal is emitted by the adjustment plate 7 pressing the connecting column 85. After being pressed, the connecting column 85 will drive the movable ball 86 and the connecting rod 87 to move. The connecting rod 87 will drive the movable rod 89 at the end to move. The movable rod 89 will drive the second electric disk 813 at the end to move. The second electric disk 813 moves closer to or further away from the first electric disk 810. The electromagnetic control rod 83 connected to the first electric disk 810 receives the signal and transmits it to the main control device 84. At this time, the main control device 84 will adjust the current to ensure the balance of the adjustment plate 7, that is, to ensure the balance of the transformer 3 inside the housing 1.
