DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Reference Figure 1-Figure 5 As shown, an anti-seepage oil-immersed transformer includes an oil tank 1, a relay 2 and an oil pillow 3. The oil tank 1 is connected to the relay 2 through a connecting pipe. A hose connector 4 is fixedly installed on the oil pillow 3 and the relay 2 through a connecting flange. A positioning tube 5 is fixedly installed on the two hose connectors 4. A metal hose 6 is provided between the two hose connectors 4. Both ends of the metal hose 6 are respectively sleeved on the two positioning tubes 5. A locking assembly for locking the metal hose 6 is provided on the hose connector 4. A supporting assembly for supporting the metal hose 6 is provided on the oil pillow 3.

[0018] A hose connector 4 is fixedly installed on the oil pillow 3 and the relay 2 through a connecting flange. The two ends of the metal hose 6 are respectively sleeved on one end of the two positioning tubes 5, and then one end of the metal hose 6 is locked on the positioning tube 5 through a locking assembly to prevent the metal hose 6 from falling off the positioning tube 5. Finally, the connection is tested for sealing to ensure that there is no leakage. The transmission hard pipe between the oil pillow 3 and the relay 2 is replaced with a metal hose 6. By using the metal hose 6 as the connecting medium, the vibration resistance of the connection between the oil pillow 3 and the relay 2 is improved, and oil leakage caused by transportation shaking is effectively prevented. The risk of oil leakage is greatly reduced, and the safety and reliability of the transformer is improved.

[0019] The locking assembly includes two mounting blocks 7 symmetrically fixedly mounted on the hose connector 4, two first threaded rods 8, two first adjustment blocks 9 respectively fixedly mounted on one end of the two first threaded rods 8, and two arc-shaped clamping blocks 10 respectively rotatably mounted on one end of the two first threaded rods 8. A threaded hole is provided on the mounting block 7, and the first threaded rod 8 is threadedly inserted into the threaded hole. Both arc-shaped clamping blocks 10 are in contact with the metal hose 6.

[0020] When one end of the metal hose 6 is sleeved on the positioning tube 5, the first adjusting block 9 is rotated to drive the first threaded rod 8 to rotate. With the cooperation of the threaded hole, the first threaded rod 8 drives the arc-shaped clamping block 10 to approach the metal hose 6. One end of the metal hose 6 is clamped and fixed on the positioning tube 5 by the two arc-shaped clamping blocks 10, which simplifies the installation process of the metal hose 6 and improves the installation efficiency.

[0021] Positioning rings 11 are fixedly installed at both ends of the metal hose 6. The positioning rings 11 are located between the hose connector 4 and the arc-shaped clamping block 10. The side of the arc-shaped clamping block 10 contacts the positioning rings 11. Therefore, the positioning rings 11 can prevent the metal hose 6 from falling off the positioning tube 5.

[0022] The supporting assembly includes two L-shaped support blocks 12 symmetrically fixedly mounted on the oil pillow 3, two moving rods 13 slidably mounted on the support blocks 12 through adjusting components, and a support block 14 fixedly mounted at one end of the two moving rods 13. A moving groove is provided on the support block 12, one end of the moving rod 13 is vertically slidably inserted in the moving groove, and the support block 14 is in contact with the metal hose 6.

One end of the support block 12 is threadedly sleeved on the second threaded rod 15. An arc groove 17 is provided on the upper surface of the support block 14, and the metal hose 6 is placed in the arc groove 17.

[0023] When the two ends of the metal hose 6 are respectively installed on the relay 2 and the oil pillow 3, the second adjusting block 16 can be rotated to drive the second threaded rod 15 to rotate, and the support block 14 can be driven to move vertically upward through the two moving rods 13 until the support block 14 contacts the metal hose 6 to support the metal hose 6. At the same time, the metal hose 6 will be inserted into the arc groove 17. The arc groove 17 can limit the two sides of the metal hose 6 to prevent the metal hose 6 from excessive shaking during transportation and installation.

[0024] In the utility model, a hose connector 4 is fixedly installed on the oil pillow 3 and the relay 2 through a connecting flange, and both ends of the metal hose 6 are respectively sleeved on one end of the two positioning tubes 5, and then one end of the metal hose 6 is locked on the positioning tube 5 through a locking assembly to prevent the metal hose 6 from falling off the positioning tube 5. Finally, the connection is tested for sealing to ensure that there is no leakage, and the transmission hard pipe between the oil pillow 3 and the relay 2 is replaced with the metal hose 6. By using the metal hose 6 as the connecting medium, the vibration resistance of the connection between the oil pillow 3 and the relay 2 is improved, and the oil leakage caused by transportation shaking is effectively prevented. The risk of oil leakage is greatly reduced, and the safety and reliability of the transformer is improved.
