[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage and is an important link in the transmission, distribution, and use of electrical energy. Transformers are classified into dry-type transformers and oil-immersed transformers according to the cooling method. Oil-immersed transformers rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooling, oil-immersed water-cooling, forced oil circulation, etc. Transformer oil has a large specific heat and good heat dissipation and cooling effects. Moreover, transformer oil has a much higher insulation strength than air and can also play a role in extinguishing electric arcs. Therefore, oil-immersed transformers are widely used in power systems, industrial and mining enterprises, transportation, post and telecommunications departments, and other occasions where voltage conversion is required.

[0003] However, the oil-immersed transformer will generate vibrations during operation, and the vibrations will cause the cable wires connected to the transformer to shake. Long-term shaking will increase the force on the terminal block, resulting in excessive friction and damage to the terminal block.

[0024] According to an embodiment of the utility model, an oil-immersed transformer with a shock absorbing function is provided. Example

[0026] The transformer structure 1 includes a main transformer 101, a level 102, a horizontal gyroscope 103, and a control module 104. The level 102 is installed on one side of the main transformer 101, the horizontal gyroscope 103 is provided at one end of the level 102, the control module 104 is provided at one end of the horizontal gyroscope 103, and the horizontal gyroscope 103 is electrically connected to the control module 104. The guide rail structure 2 includes a guide fixed rail 201 and an adjustment groove 202. The guide fixed rail 201 is provided with an adjustment groove 202, and the adjustment structure 3 is installed in the adjustment groove 202. The level meter 102 is used to find the level during the installation process to prevent the main transformer 101 from being installed tilted. The horizontal gyroscope 103 is connected to the control module 104, and can monitor the horizontal state of the main transformer 101 in real time, and set a certain monitoring threshold for the control module 104. When the horizontal shake detected by the horizontal gyroscope 103 is greater than a certain angle and has not been restored to the level for a long time, an alarm signal will be triggered, triggering its alarm 11 to alert passers-by and send an alarm signal to the remote control terminal through the wireless signal transceiver module of the control module 104.

[0027] The adjustment structure 3 includes a first connection seat 301, a threaded sleeve 302, a threaded rod 303, a lug 304, and an adjustment hole 305. The bottom end of the first connection seat 301 is fixedly connected to the threaded sleeve 302, the threaded sleeve 302 is connected to the threaded rod 303, the threaded rod 303 is limited and rotatably connected to the lug 304, the threaded rod 303 is installed on the adjustment groove 202 through the lug 304, and an adjustment hole 305 is opened at one end of the threaded rod 303. The guide fixing rail 201 of the guide rail structure 2 is aligned with the fixing device for installing the transformer. Next, the first connecting seat 301 is rotatably connected to the first connecting rod 5, and the threaded rod 303 of the adjusting structure 3 is introduced into the adjusting hole 305 through a hexagonal wrench for rotation, so that the threaded rod 303 rotates to drive the threaded sleeve 302 and the first connecting seat 301 to perform linear adjustment in the adjusting groove 202, so as to adjust the inclination angle of the first connecting rod 5. Since the change of the inclination angle will change the force on the connecting rod, and at the same time change the force on the first spring 6, the shaking energy reduction effect of the cable can be changed, so that it can be adjusted according to actual conditions.

The sliding friction between the sliding block 804 and the connecting sleeve rod 9 can convert energy, thereby offsetting the vibration energy. One end of the first connecting rod 5 and the second connecting rod 7 is rotatably and slidably damped and installed on the sliding sleeve rod 4.

[0030] In summary, by means of the above technical solutions of the present utility model, the cable wire body connected to the transformer structure 1 is docked with the connection structure 8. The connection structure 8 cooperates with other structures to reduce the shaking energy of the cable, reduce unnecessary shaking. The level 102 is used for leveling during the installation process to prevent the main transformer 101 from being installed obliquely. The horizontal gyroscope 103 is connected to the control module 104, which can monitor the horizontal state of the main transformer 101 in real time. A certain monitoring threshold is set for the control module 104. When the horizontal shaking monitored by the horizontal gyroscope 103 is greater than a certain angle and the level is not restored for a long time, an alarm signal will be triggered, causing the alarm 11 to trigger, reminding the passing crowd and sending an alarm signal to the remote control terminal through the wireless signal transceiver module of the control module 104. The guiding fixed rail 201 of the guide rail structure 2 is docked with the fixing device for installing the transformer.

Since the change of the inclination angle will change the force on the connecting rod and at the same time change the force on the first spring 6, the effect of reducing the shaking energy of the cable can be changed, so that it can be adjusted according to the actual situation. The second connecting seat 801 is rotatably connected to one end of the second connecting rod 7. The connecting sleeve rod 9 is provided with a limiting block, which can limit the maximum displacement distance of the sliding block 804 on the connecting sleeve rod 9. The sliding friction between the sliding block 804 and the connecting sleeve rod 9 can convert energy, thereby offsetting the vibration energy. One end of the first connecting rod 5 and the second connecting rod 7 is rotatably and slidably damped and installed on the sliding sleeve rod 4. The first spring 6 is installed on the sliding sleeve rod 4 between the connection ends of the first connecting rod 5 and the second connecting rod 7. The connecting sleeve rod 9 is connected between the two sliding sleeve rods 4, which can improve the connection stability of the sliding sleeve rod 4.
