Description

Technical Field

[0001] The utility model relates to the technical field of transformer installation, and more specifically to a high-voltage transformer with an installation protection function. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. It can be divided into power transformers and special transformers according to its use. The insulation structure and insulation blocks are placed between the parts that need to be insulated in the transformer to adapt to the effects of various voltages and ensure a stable electric field in the transformer. In many cases, such as lightning strikes, the electric field of the transformer winding is unevenly distributed in the axial direction of the coil, and there is axial field strength. At the same time, there is an uneven electric field between the high and low voltage windings, and between the winding end and the iron yoke. There is also a radial electric field, so there is a composite electric field between the windings.

[0003] Although the existing ultra-high voltage transformer is provided with insulating parts inside, the structure of the insulating parts is too simple. In thunderstorm weather or humid environment, the electric field inside the transformer will be very uneven, and the electric field cannot be reasonably balanced. There are certain safety hazards, poor reliability and low safety performance. A patent for an insulation structure of an ultra-high voltage transformer, the patent announcement number is CN 205984597 U, which can effectively insulate the transformer, has more diverse insulation forms, high safety performance, good reliability, effectively avoids the chaos of the electric field inside the ultra-high voltage transformer, effectively ensures the stability of the electric field inside the transformer, and effectively avoids the occurrence of accidents, thereby effectively solving the problems of poor insulation effect and too simple insulation form.

[0004] However, the ultra-high voltage transformer in patent announcement number CN 205984597 U needs to be hoisted during the installation process, and then installed at a high altitude. Due to the acceleration and impact force generated during the lowering process during the hoisting and placement, the lack of necessary protection can easily lead to the destruction of the high-voltage transformer, damage to the transformer, damage to the power supply system, affecting people's normal production and living electricity consumption, and causing economic losses. Therefore, we propose a high-voltage transformer with installation protection function to solve the above-mentioned problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-voltage transformer with installation protection function, which can ensure the stability of the high-voltage transformer body during the buffering and energy absorption process, effectively avoid the damage of the high-voltage transformer body due to impact factors during the hoisting and installation process, and play a good protective role for the transformer body during the installation process.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A high-voltage transformer with installation protection function comprises a high-voltage transformer body, and a mounting base is arranged below the high-voltage transformer body;

[0008] A through hole is horizontally opened in the middle of the surface of the mounting base, a guide rod is fixedly connected to the inner side of the through hole, a movable seat is symmetrically installed on the outside of the guide rod, springs are sleeved on both ends of the guide rod, one end of the spring is connected to the movable seat, and the other end of the spring is connected to the inner wall of the end of the through hole, guide pillars are welded on the outer walls of both sides of the movable seat protruding from the top of the through hole, guide plates are arranged on both sides of the top of the through hole, the bottom ends of which are welded to the upper surface of the mounting base, guide holes are opened on the surface of the guide plates with clearance matching with the guide pillars, the top ends of the symmetrically arranged movable seats are fixedly connected to the first connecting shaft through the bracket, the bottom of the high-voltage transformer body is welded with a second connecting shaft corresponding to the first connecting shaft through the bracket, and the first connecting shaft and the second connecting shaft are rotatably connected to the support arm;

[0009] Both sides of the through hole are provided with damping rods, the bottom ends of which are fixedly connected to the upper surface of the mounting base and the movable ends of which are connected to the bottom of the high-voltage transformer body;

[0010] A guide corner guard that fits the corner of the high-voltage transformer body is welded on the edge of the upper surface of the mounting base.

[0011] Furthermore, the lower surface of the mounting base is symmetrically bonded with rubber pads, and the lower surfaces of the symmetrically arranged rubber pads are integrally formed with buffer bosses in an array.

[0012] Furthermore, a buffer zone is provided between two adjacent buffer bosses.

[0013] Furthermore, bearings are installed at both ends of the support arm, and the bearings are respectively interference-connected with the first connecting shaft and the second connecting shaft.

[0018] (1) In this scheme, the guide column cooperates with the guide hole opened on the surface of the guide plate to slide toward the end of the through hole, and the movable seat cooperates with the guide rod to move synchronously, so that the spring is compressed and deformed to absorb energy. The high-voltage transformer body will move downward, and the movable end of the damping rod will shrink, reducing the energy transfer caused by vibration, impact or other forms of movement, thereby improving the energy absorption effect and avoiding the high-voltage transformer body from jumping up and down due to the rebound force of the spring. At the same time, the high-voltage transformer body is guided by the guide corner guard during the downward movement, ensuring the stability of the high-voltage transformer body during the buffering and energy absorption process, which can effectively avoid the high-voltage transformer body from being damaged due to impact factors during the hoisting and installation process, and play a good protective role for the transformer body during the installation process.

[0019] (2) In this solution, the buffer boss arranged on the lower surface of the rubber pad abuts against the installation surface, and the buffer boss is squeezed and deformed. At the same time, the buffer zone cooperates with the deformation of the buffer boss, so that the rubber pad can isolate vibration and absorb impact force, thereby playing a good protective role for the high-voltage transformer body during the installation process.

Example

[0028] See also Figure 1-5 , a high-voltage transformer with installation protection function, comprising a high-voltage transformer body 1, and a mounting base 2 is arranged below the high-voltage transformer body 1;

[0029] A through hole 3 is horizontally opened in the middle of the surface of the mounting base 2, a guide rod 4 is fixedly connected to the inner side of the through hole 3, a movable seat 5 is symmetrically installed on the outside of the guide rod 4, springs 6 are sleeved on both ends of the guide rod 4, one end of the spring 6 is connected to the movable seat 5, and the other end of the spring 6 is connected to the inner wall of the end of the through hole 3, guide pillars 7 are welded on the outer walls of both sides of the movable seat 5 protruding from the top of the through hole 3, guide plates 8 are arranged on both sides of the top of the through hole 3, and the bottom ends of the guide plates 8 are welded to the upper surface of the mounting base 2, and guide holes 9 with clearances matching the guide pillars 7 are opened on the surface of the guide plates 8, the top ends of the symmetrically arranged movable seats 5 are fixedly connected to the first connecting shaft 10 through a bracket, and a second connecting shaft 11 corresponding to the first connecting shaft 10 is welded to the bottom of the high-voltage transformer body 1 through a bracket, and a support arm 12 rotatably connected between the first connecting shaft 10 and the second connecting shaft 11;

[0030] Damping rods 13 are arranged on both sides of the through hole 3, the bottom end of which is fixedly connected to the upper surface of the mounting base 2 and the movable end of which is connected to the bottom of the high-voltage transformer body 1;

[0031] A guide corner guard 14 is welded on the upper surface edge of the mounting base 2 and fits the corner of the high-voltage transformer body 1;

[0032] It should be noted that after the high-voltage transformer body 1 is hoisted to the designated installation position at a high altitude by the hoisting equipment, it is lowered so that the mounting base 2 contacts the mounting surface. During this process, the downward impact force generated by the acceleration causes the two ends of the support arm 12 to respectively cooperate with the first connecting shaft 10 and the second connecting shaft 11 to rotate, and at the same time, the guide column 7 cooperates with the guide hole 9 opened on the surface of the guide plate 8 to slide toward the end of the through hole 3, and the movable seat 5 cooperates with the guide rod 4 to move synchronously, compressing and deforming the spring 6 to absorb energy, the high-voltage transformer body 1 will move downward, and the movable end of the damping rod 13 will shrink, reducing the energy transfer caused by vibration, impact or other forms of movement, thereby improving the energy absorption effect and avoiding the rebound force of the spring 6 causing the high-voltage transformer body 1 to jump up and down. At the same time, the high-voltage transformer body 1 is guided by the guide corner guard 14 during the downward movement, which ensures the stability of the high-voltage transformer body 1 during the buffering energy absorption process, and can effectively avoid the high-voltage transformer body 1 from being damaged due to impact factors during the hoisting and installation process.

[0033] like Figure 5 As shown, the lower surface of the mounting base 2 is symmetrically bonded with rubber pads 16, and the lower surface of the symmetrically arranged rubber pads 16 is integrally formed with buffer bosses 17 in an array, and a buffer zone is provided between two adjacent buffer bosses 17;

[0034] It should be noted that the buffer boss 17 arranged on the lower surface of the rubber pad 16 is in contact with the installation surface, and is squeezed and deformed by the buffer boss 17. At the same time, the buffer zone cooperates with the deformation of the buffer boss 17, so that the rubber pad 16 can isolate vibration and absorb impact force, thereby playing a good protective role for the high-voltage transformer body 1 during the installation process.

[0035] like Figure 3 As shown, bearings are installed at both ends of the support arm 12, and the bearings are respectively connected with the first connecting shaft 10 and the second connecting shaft 11 by interference fit;

[0036] It should be noted that the friction between the support arm 12 and the first connecting shaft 10 and the second connecting shaft 11 is reduced, and the rotation accuracy of the support arm 12 is guaranteed.

[0037] like Figure 1 As shown, a rib plate 15 is welded to the root of the outer facade of the guide corner guard 14, and a plurality of rib plates 15 are provided;

[0038] It should be noted that the structural strength of the junction between the bottom end of the guide corner guard 14 and the upper surface of the mounting base 2 can be improved, thereby effectively preventing the guide corner guard 14 from being deformed due to stress.

[0039] like Figure 1 As shown, a lifting lug is fixedly connected to the top edge of the high-voltage transformer body 1, and a plurality of lifting lugs are symmetrically arranged;

[0040] It should be noted that the lifting lug is connected to the lifting equipment via a lifting rope, so as to facilitate the lifting work of the high-voltage transformer body 1.

[0041] like Figure 2 As shown, the edge of the mounting base 2 is provided with a mounting hole, and a plurality of the mounting holes are symmetrically arranged;

[0042] It should be noted that it is convenient to fix the mounting base 2 in the designated installation area.

[0043] During use: after the high-voltage transformer body 1 is hoisted to the designated installation position at a high altitude by the hoisting equipment, it is lowered so that the mounting base 2 contacts the mounting surface. During this process, the downward impact force generated by the acceleration causes the two ends of the support arm 12 to respectively cooperate with the first connecting shaft 10 and the second connecting shaft 11 to rotate, and at the same time, the guide column 7 cooperates with the guide hole 9 opened on the surface of the guide plate 8 to slide toward the end of the through hole 3, and the movable seat 5 cooperates with the guide rod 4 to move synchronously, compressing and deforming the spring 6 to absorb energy, the high-voltage transformer body 1 will move downward, and the movable end of the damping rod 13 will contract, reducing the energy transfer caused by vibration, impact or other forms of movement, thereby improving the energy absorption effect and avoiding the high-voltage transformer body 1 from jumping up and down due to the rebound force of the spring 6. At the same time, the high-voltage transformer body 1 is guided by the guide corner guard 14 during the downward movement, thereby ensuring the stability of the high-voltage transformer body 1 during the buffering energy absorption process.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
