Its main function is to reduce the voltage of high-voltage power grid (10(6)kV or 35kV) to the low-voltage (230 / 400V) bus voltage used by users. This type of transformer is suitable for AC 50(60)Hz power system and supplies three-phase electricity with a maximum rated capacity of 2500kVA.

[0003] According to a disclosed easy-to-adjust oil-immersed transformer (publication number: CN213366322U), the above application includes an oil-immersed transformer box, on the outside of the box, corrugated sheets are evenly fixedly installed near the upper surface, on one side of the box, an oil drain valve is fixedly installed near a corner of the lower surface for discharging the oil inside the transformer, and on the front surface of the oil-immersed transformer box, a grounding stake is fixedly installed near the middle of the lower surface for effectively grounding the transformer to the ground.

[0004] However, in actual use, the above-mentioned equipment can only be adjusted in angle during installation, but cannot be adjusted up and down. This limitation is particularly obvious when the vertical position of the transformer needs to be fine-tuned. In view of this, we propose an oil-immersed transformer that is easy to adjust. Utility Model Content

[0013] Preferably, a rubber pad is fixedly connected to the end surface of the abutment block.

[0014] Preferably, the threaded sleeve is sleeved with a limiting rod to prevent the threaded sleeve from rotating.

[0015] Preferably, there are four adjustment components, which are centrally symmetrically arranged on the inner wall of the mounting base, and the angle and height of the transformer body are adjusted by the four adjustment components.

[0016] Preferably, a rack is provided at one end of the button and the abutment block close to the inside of the adjustment ring, and the rack is meshed with a gear.

DETAILED DESCRIPTION

[0026] like Figure 1-4 As shown, the utility model provides a technical solution: an oil-immersed transformer that is easy to adjust, including a transformer body 1, a rotating shaft 101 is fixedly connected to the side wall of the transformer body 1, the rotating shaft 101 is rotatably connected to the mounting seat 2, an adjusting component is arranged on the inner wall of the mounting seat 2, and the number of the adjusting components is set to four, and the four adjusting components are symmetrically arranged on the inner wall of the mounting seat 2, and the angle and height of the transformer body 1 are adjusted by the four adjusting components, the adjusting component includes a threaded rod 3, the inner wall of the mounting seat 2 is sleeved with the threaded rod 3 and the limiting rod 5, one end of the threaded rod 3 is fixedly connected to the output end of the motor 4, the motor 4 is fixedly connected to the side wall of the mounting seat 2, the side wall of the threaded rod 3 is threadedly connected to the threaded sleeve 6, the threaded sleeve 6 is sleeved with the limiting rod 5 to prevent the threaded sleeve 6 from rotating, The threaded sleeve 6 is hinged to one end of the hydraulic rod 7, and the other end of the hydraulic rod 7 is fixedly connected to the rotating ball 8, which is rotatably connected to the bottom of the transformer body 1. The outer wall of the hydraulic rod 7 is sleeved with a spring 9, and the side wall of the hydraulic rod 7 is threadedly connected with an adjusting ring 10. The side wall of the adjusting ring 10 is sleeved with a button 11 and an abutment block 12, and the inner bottom of the adjusting ring 10 is sleeved with a rotating shaft 13. The side wall of the rotating shaft 13 is fixedly connected with a gear 14, and the rotating shaft 13 is fixedly connected to one end of a coil spring 15, and the other end of the coil spring 15 is fixedly connected to the inner bottom of the adjusting ring 10. A rack is provided at one end of the button 11 and the abutment block 12 close to the inside of the adjusting ring 10, and the rack is meshed with the gear 14. The button 11 moves into the adjusting ring 10 to drive the gear 14 to rotate, and further drives the abutment block 12 to move into the adjusting ring 10.

[0027] In one embodiment of the utility model, the motor 4 is started, driving the threaded rod 3 to rotate, further driving the threaded sleeve 6 to move laterally, so that the hydraulic rod 7 moves laterally, lifting or lowering the transformer body 1, and the angle and height of the transformer body 1 can be adjusted through four adjustment components. Further, the button 11 is pressed to make the button 11 move into the adjustment ring 10, thereby driving the gear 14 to rotate, and the rotation of the gear 14 drives the abutment block 12 to move into the adjustment ring 10, thereby canceling the abutment of the abutment block 12 on the side wall of the hydraulic rod 7, and then the adjusting ring 10 can be rotated to make the adjusting ring 10 move on the side wall of the hydraulic rod 7 to achieve compression of the spring 8, thereby adjusting the stiffness of the spring 8, and the smaller stiffness causes the spring 8 to produce a larger deformation when it is impacted, thereby effectively dispersing the impact energy and protecting the transformer body 1 from damage; the larger stiffness can provide stronger support and stability when it is necessary to resist dynamic loads.

[0028] In addition, in order to further improve the stability of the adjustment ring 10, a rubber pad 16 is fixedly connected to the end face of the abutment block 12. The rubber pad 16 can increase the contact area between the abutment block 12 and the hydraulic rod 7 to prevent the adjustment ring 10 from slowly rotating under the pressure of the spring 8, causing the stiffness of the spring 8 to change.

[0029] In the utility model, when in use, the motor 4 is started, driving the threaded rod 3 to rotate, further driving the threaded sleeve 6 to move horizontally, so that the hydraulic rod 7 moves horizontally, lifting or lowering the transformer body 1, and the angle and height of the transformer body 1 can be adjusted through four adjustment components. Further, the button 11 is pressed to make the button 11 move into the adjustment ring 10, thereby driving the gear 14 to rotate, and the rotation of the gear 14 drives the abutment block 12 to move into the adjustment ring 10, thereby canceling the abutment of the abutment block 12 on the side wall of the hydraulic rod 7, and then the adjustment ring 10 can be rotated to adjust the adjustment ring 10. When the side wall of the hydraulic rod 7 moves, the spring 8 is compressed, and then the stiffness of the spring 8 is adjusted. The smaller stiffness causes the spring 8 to produce a larger deformation when it is impacted, thereby effectively dispersing the impact energy and protecting the transformer body 1 from damage; the larger stiffness can provide stronger support and stability when it is necessary to resist dynamic loads. Furthermore, the end face of the abutment block 12 is fixedly connected with a rubber pad 16. The rubber pad 16 can increase the contact area between the abutment block 12 and the hydraulic rod 7 to prevent the adjustment ring 10 from slowly rotating under the pressure of the spring 8, causing the stiffness of the spring 8 to change.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
