Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer that prevents oil leakage faults. Background Technology

[0002] Patent publication number CN218497933U discloses a power transformer with an oil leakage prevention function, including a transformer body. An oil drain port is located on one side of the bottom center of the transformer body. An oil box is fixedly installed on the bottom center of the transformer body, and an oil hopper is located on the bottom side of the oil box near the oil drain port. This invention, by setting up an oil box, allows oil to flow into the oil hopper along the drain port when leakage occurs, and then seep into the oil box through the hopper. As the oil level in the oil box continues to increase, oil enters a connecting pipe. At this point, a distance sensor detects this and sends a command to an alarm. The alarm is remotely connected to the monitoring equipment of the power management department. When the alarm receives the command, it sends a signal to the monitoring equipment of the management department, allowing maintenance workers to quickly arrive at the site to repair the transformer body, thereby preventing transformer failure and ensuring normal power transmission.

[0003] In this patent, when the transformer leaks oil, an alarm sends a signal to the management department, which then dispatches personnel to the site for repairs. However, while waiting for the personnel to arrive, the transformer continues to leak oil. When the oil in the connecting pipe reaches its limit, oil continues to be pumped into the connecting pipe. If the personnel fail to arrive on time, the excessive amount of oil in the connecting pipe will cause the oil pressure in the connecting pipe to become too high, leading to the connecting pipe bursting and causing even more oil leakage, thus increasing the workload of transformer maintenance.

[0024] The pumping unit includes an oil pump 16 suspended in the oil receiving tank 9. The bottom surface of the oil pump 16 is fixedly connected to the base 15. An L-shaped support rod 14 is fixed on each side of the base 15. Both L-shaped support rods 14 are fixed to the bottom surface of the transformer body 1. The output end of the oil pump 16 is connected to the delivery pipe 17. The delivery pipe 17 is connected to the bottom surface of the transformer body 1. The bottom surface of the distance sensor 13 is flush with the top surface of the oil pump 16. The length of the distance sensor 13 is greater than the length of the oil outlet pipe 12.

[0025] The connector includes a rectangular frame 8 fixedly sleeved on the outside of the oil receiving groove 9. The rectangular frame 8 is fixed to the bottom surface of the transformer body 1 by bolts 11. The bottom surface of the rectangular frame 8 is vertically penetrated by multiple arrayed countersunk holes 23. The bottom surface of the transformer body 1 is vertically provided with threaded grooves 24 that are adapted to the countersunk holes 23. A bolt 11 is sleeved in each countersunk hole 23. The end of the bolt 11 is threaded into the threaded groove 24. The top surface of the rectangular frame 8 is provided with a guide. The guide is slidably connected to the bottom surface of the transformer body 1. The bottom surface of the transformer body 1 is adapted to the oil receiving groove 9 with a sealing groove 18. The sealing groove 18 is provided with a matching sealing ring 19. The sealing ring 19 is fixed to the top surface of the oil receiving groove 9.

[0026] The guide includes two dovetail blocks 25 symmetrically connected to the top surface of the rectangular frame 8. A pair of dovetail grooves 26 are symmetrically opened on the bottom surface of the transformer body 1. A dovetail block 25 is slidably connected in each dovetail groove 26. A pair of grooves 10 communicating with the dovetail grooves 26 are provided on the bottom surface of the transformer body 1. A pair of storage grooves 21 are provided on the top surface of the rectangular frame 8. A support block 20 is slidably connected in each storage groove 21. A dovetail block 25 is fixed on the top surface of each support block 20. A compressed spring 22 is fixed between the support block 20 and the bottom wall of the storage groove 21.

[0027] By installing a pumping device inside the oil receiving tank 9 and placing it on the bottom surface of the transformer body 1, when oil leakage occurs, the oil will be collected in the oil receiving tank 9. The pumping device will then return the leaked oil from the oil receiving tank 9 to the transformer body 1. At the same time, the alarm 7 will transmit the oil leakage signal to the control department, thereby slowing down the oil leakage rate of the transformer body 1. This prevents excessive oil leakage from the transformer body 1 from filling the oil receiving tank 9 while waiting for staff to arrive at the leaking transformer body 1, which would then cause oil to leak between the oil receiving tank 9 and the transformer body 1.

[0028] Working principle: When oil leaks from the oil outlet pipe 12 in the transformer body 1, the oil will fall into the oil receiving tank 9. The oil receiving tank 9 collects the leaked oil, and the oil level in the oil receiving tank 9 rises continuously. At the same time, the distance sensor 13 detects the oil level in the oil receiving tank 9 in real time. When the oil level in the oil receiving tank 9 reaches the bottom of the distance sensor 13, the alarm 7 sounds an alarm and transmits a signal to the control department. The department will dispatch personnel to the site to repair the transformer. Simultaneously, the oil pump 16 starts, and the oil pump 16 collects the oil. The oil in tank 9 is extracted and returned to the transformer body 1 through the conveying pipe 17, thereby slowing down the rise of the oil level in tank 9 and preventing the oil level in tank 9 from becoming too high and leaking out. When the staff arrives at the site to repair the transformer, they first loosen and remove all the bolts 11. After the bolts 11 are removed, the compressed spring 22 returns to its original position. When the spring 22 returns to its original position, the support block 20 extends out of the receiving groove 21, causing the rectangular frame 8 to move downward with the oil tank 9. The movement causes the bottom surface of the rectangular frame 8 to separate from the bottom surface of the transformer body 1, and the sealing ring 19 to leave the sealing groove 18. Then, the oil receiving groove 9 is slid forward, causing the dovetail block 25 on the top surface of the rectangular frame 8 to slide out from the dovetail groove 26 and move into the groove 10. Then, the oil receiving groove 9 is removed downwards, allowing the oil outlet pipe 12 to leak out. The leaking oil outlet pipe 12 can then be repaired. After the repair is completed, the oil receiving groove 9 is installed back onto the bottom surface of the transformer body 1. During installation, the dovetail block 25 is inserted into the groove 10, and then... The oil receiving groove 9 is pushed backward, causing the dovetail block 25 to slide from the groove 10 into the dovetail groove 26. At this time, the countersunk hole 23 is aligned with the threaded groove 24. Then, each bolt 11 is installed back onto the bottom surface of the transformer body 1. When the bolts 11 are tightened, the oil receiving groove 9 and the rectangular frame 8 rise, causing the sealing ring 19 to be inserted into the sealing groove 18 and abut against the top wall of the sealing groove 18. At the same time, the support block 20 moves into the receiving groove 21, causing the spring 22 to be compressed, so that the top surface of the rectangular frame 8 abuts against the bottom surface of the transformer body 1.
