Description

Seismic-resistant and stable power transformer Technical Field

[0001] This utility model relates to the field of power transformers, and more particularly to earthquake-resistant and stable power transformers. Background Technology

[0002] Power transformers are crucial electrical equipment in power systems. There are dry-type transformers and oil-immersed transformers, which are mainly used to change the level of AC voltage to adapt to different power transmission and distribution needs. Oil-immersed transformers are the common type of transformer in large outdoor power systems, and are mostly mounted on support columns using mounting brackets.

[0003] Most existing power transformer installations are equipped with fixed cable support structures. During use, the cables are directly installed on the power transformer and connected to external cable brackets. During an earthquake, various shock-absorbing structures can easily cause deviations in the displacement between the cables and the power transformer. The fixed support structure can also increase the stress at the connection points, leading to leakage and other issues. This reduces the stability and reliability of the operation during earthquakes, resulting in a decline in the effectiveness and safety of the power transformer installation.

[0004] Therefore, in response to the problem that existing power transformer devices are prone to displacement deviation between cables and power transformers during earthquakes due to various vibration reduction structures, which increases the stress at the connection and causes leakage, thus reducing the effectiveness and safety of the power transformer device, a seismically stable power transformer can be designed. Summary of the Invention

[0005] To overcome the problem that existing power transformer installations, during earthquakes, are prone to displacement deviations between cables and power transformers due to various vibration damping structures, which can increase the stress at the connection points and lead to leakage, thus reducing the effectiveness and safety of the power transformer installations.

[0006] The technical solution of this utility model is as follows: a seismically stable power transformer, including a transformer body; and a support frame and a support platform. The support frame is installed at the lower end of the transformer body. A second mounting groove is provided on both the front and back of one side of the support platform. A movable frame for moving cables is slidably connected to the inner side of the second mounting groove. A threaded rod is threadedly connected to one side end of the movable frame. The threaded rod is rotatably connected to the support platform through a rotating shaft. A receiving groove is provided at the upper end of the movable frame. A limit bolt is provided at one side end of the movable frame. A lifting platform is slidably connected to the inner side of the receiving groove. A rotating seat is installed at the upper end of the lifting platform. A coiling roller for winding cables is rotatably connected to the inner side of the rotating seat. A third spring for cable resetting is installed between the rotating seats of the coiling roller and the rotating seat.

[0007] Preferably, the transformer body is supported by a support frame and a support platform, and the cable is wound by a coiling roller. The moving frame is moved by a threaded rod and a second mounting groove. At the same time, the lifting platform and the rotating seat are moved and fixed by the receiving groove and the limiting bolt, thereby adjusting the position of the coiling roller and relaxing the tension of the cable. When the coiling roller rotates, the third spring and the rotating seat are used to support the coiling roller to rotate and reset.

[0008] Preferably, a first mounting slot is provided between the two second mounting slots, and a telescopic rod is installed at the upper end of the first mounting slot.

[0009] Preferably, the upper end of the support platform is provided with a sliding groove, and the inner side of the sliding groove is provided with a vibration-damping rubber pad.

[0010] Preferably, a fixing plate is fixed to the other side baffle of the support platform, and a support rod is slidably connected between the front and rear fixing plates.

[0011] Preferably, a first spring is provided on the outer side of the support rod, and the first spring is connected to the front and rear fixing plates by bolts.

[0012] Preferably, a damper is installed on the inner side of the first mounting groove, and a mounting platform is installed on one end of the damper.

[0013] Preferably, a second spring is installed between the damper and the mounting platform, a support ring is fixed to one end of the mounting platform, and a clamping plate is rotatably connected to one end of the support ring via a rotating shaft.

[0014] The beneficial effects of this utility model are:

[0015] This earthquake-resistant and stable power transformer supports the transformer body and connects the cables via a support frame and support platform. The cables are wound around a coiling roller, and the position of the coiling roller is adjusted using a movable frame and a rotating seat to relax the cable tension. During an earthquake, a third spring and a rotating seat are used to support the coiling roller to rotate and reset, thus supporting the cables. This reduces the force of displacement between the cables, decreases the possibility of cable detachment, reduces the possibility of leakage, and improves the stability of the device during earthquakes.

[0023] Please refer to Figures 1-5. This utility model provides an embodiment of an anti-seismic and stable power transformer, including a transformer body 1; it also includes a support frame 2 and a support platform 3. The support frame 2 is installed at the lower end of the transformer body 1. The support platform 3 has a second mounting groove 5 on both the front and back of one side. A movable frame 17 for moving cables is slidably connected to the inner side of the second mounting groove 5. A threaded rod 18 is threadedly connected to one side of the movable frame 17. The threaded rod 18 is rotatably connected to the support platform 3 via a rotating shaft. A receiving groove 19 is opened at the upper end of the movable frame 17. A limit bolt 20 is provided at one side of the movable frame 17. A lifting platform 21 is slidably connected to the inner side of the receiving groove 19. A rotating seat 22 is installed at the upper end of the lifting platform 21. A coiling roller 23 for winding cables is rotatably connected to the inner side of the rotating seat 22. A cable repositioning device is installed between the rotating seat 22 and the coiling roller 23. The third spring 24 supports the transformer body 1 through the support frame 2 and the support platform 3, and winds the cable through the coiling roller 23. The moving frame 17 is moved through the threaded rod 18 and the second mounting groove 5. At the same time, the lifting platform 21 and the rotating seat 22 are moved and fixed by the receiving groove 19 and the limiting bolt 20, thereby adjusting the position of the coiling roller 23 and relaxing the tension of the cable. When the coiling roller 23 rotates, the third spring 24 and the rotating seat 22 support the coiling roller 23 to rotate and reset. A first mounting groove 4 is opened between the two second mounting grooves 5. A telescopic rod 6 is installed at the upper end of the first mounting groove 4. The telescopic rod 6 balances the two ends of the transformer body 1. A sliding groove 7 is opened at the upper end of the support platform 3. A vibration isolation rubber pad 8 is set on the inner side of the sliding groove 7. The vibration isolation rubber pad 8 supports and reduces the impact of earthquakes on the transformer body 1 and the support frame 2.

[0024] Please refer to Figures 3-4. In this embodiment, a fixing plate 9 is fixedly connected to the baffle on the other side of the support platform 3. A support rod 10 is slidably connected between the front and rear fixing plates 9. The support rod 10 and the fixing plates 9 support the two support platforms 3. A first spring 11 is provided on the outside of the support rod 10. The first spring 11 is connected to the front and rear fixing plates 9 by bolts. The first spring 11 supports the two fixing plates 9 to control the front and rear distance between the two support platforms 3 and reduce the impact of front and rear displacement during earthquakes. A damper 12 is installed on the inner side of the first mounting groove 4. A mounting platform 13 is installed on one side of the damper 12. The support platform 3 and the mounting platform 13 are supported by the damper 12 and the second spring 14 to reduce vibration and protect the transformer body 1. A second spring 14 is installed between the damper 12 and the mounting platform 13. A support ring 15 is fixedly connected to one side of the mounting platform 13. A clamping plate 16 is rotatably connected to one side of the support ring 15 through a rotating shaft. The mounting platform 13 is fixed on the mounting column by the clamping plate 16 and the support ring 15.

[0025] During installation, firstly, two mounting platforms 13 are fixed on the two side mounting columns by clamping plates 16 and support rings 15, and dampers 12 are installed by the first mounting groove 4. Next, two fixing plates 9 are supported by the first spring 11, and two support platforms 3 are supported by support rods 10 and fixing plates 9. Then, the transformer body 1 is supported by vibration isolation rubber pads 8 and support frames 2. Finally, the cable is wound by the coiling roller 23 to connect the cable and the transformer body 1.

[0026] In use, firstly, the moving frame 17 is moved by the threaded rod 18. At the same time, the height of the lifting platform 21 and the rotating seat 22 is adjusted to adjust the position of the coil roller 23, thereby easing the tension of the cable. When the coil roller 23 rotates, the third spring 24 and the rotating seat 22 are used to support the coil roller 23 to rotate and reset. Then, the first spring 11, in conjunction with the support rod 10, supports the two fixed plates 9 to control the front-to-back distance between the two support platforms 3 and reduce the impact of front-to-back displacement during an earthquake. At the same time, the damper 12 and the second spring 14 support the support platform 3 and the mounting platform 13, and the vibration isolation rubber pad 8 supports and reduces the impact of an earthquake on the transformer body 1 and the support frame 2 to protect the transformer body 1. Finally, the telescopic rod 6 balances the two ends of the transformer body 1, reduces the load on the damper 12, and adjusts the distance between the two support platforms 3 and the mounting column.

[0027] Through the above steps, the transformer body 1 is supported by the support frame 2 and the support platform 3, and the cable is wound by the coiling roller 23. The moving frame 17 is moved by the threaded rod 18 and the second mounting groove 5. At the same time, the lifting platform 21 and the rotating seat 22 are moved and fixed by the receiving groove 19 and the limiting bolt 20, thereby adjusting the position of the coiling roller 23 and relaxing the tension of the cable. When the coiling roller 23 rotates, the third spring 24 and the rotating seat 22 are used to support the coiling roller 23 to rotate and reset. This solves the problem that in existing power transformer devices, various shock absorption structures can easily cause displacement deviation between the cable and the power transformer during earthquakes, thereby increasing the stress at the connection and causing leakage, which leads to a decrease in the performance and safety of the power transformer device.
