[0002] An oil-immersed silicon steel sheet transformer is a type of transformer that uses silicon steel sheets as its core material and is insulated and cooled by transformer oil.

[0003] When testing the oil tank's seal through the pressure port, the pressure port is directly connected to the oil tank. During testing, oil can easily seep into the inside of the pressure port, not only contaminating the testing equipment but also leaving oil residue inside, which is detrimental to subsequent sealing operations.

[0004] To address the aforementioned technical issues, CN222233416U discloses a sealing structure for an oil-immersed transformer tank. This structure involves a threaded cylinder and a sealing sleeve. A threaded groove and a through hole are formed on the side wall of the oil-immersed transformer tank. A sealing washer at one end of the sealing sleeve is placed inside the threaded groove, and the other end of the sealing sleeve passes through the through hole. The threaded cylinder is then tightened inside the threaded groove to compress and fix the sealing washer. A spring in the sealing sleeve pulls on the sealing plug, causing the sealing plug to seal the through hole.

[0005] The existing technology has the following shortcomings: the sealing structure at the bushing of the oil-immersed silicon steel sheet transformer cannot be disassembled, which leads to oil seepage and leakage at the connection point after long-term use, and is prone to causing accidents.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a detachable sealed structure oil-immersed silicon steel sheet transformer, including a top cover 1;

[0035] The top of the top cover 1 is provided with a connecting mechanism 3 for sealing connection. The connecting mechanism 3 is equipped with a detachable sealing mechanism 4 and a wiring mechanism 5 adapted to the sealing mechanism 4. The bottom of the top cover 1 is provided with a storage mechanism 2 connected to the top cover 1.

[0036] The connecting mechanism 3 includes;

[0037] A connecting pipe 31 is connected to the top of the top cover 1, and an adapter component is provided inside the connecting pipe 31.

[0038] Sealing mechanism 4 includes;

[0039] A sealing tube 41 is inserted into the inside of the top cover 1, and an installation component is provided on the outside of the sealing tube 41.

[0040] Preferred;

[0041] like Figure 5 As shown, the adapter components include;

[0042] The internally threaded connector 32 is fixedly installed on the inner side wall of the connecting pipe 31, and the top end of the connecting pipe 31 is provided with a connecting groove 33;

[0043] The connecting pipe 31 is used to allow the wiring mechanism 5 to pass through the top cover 1, thereby realizing the internal and external connection. The internal threaded pipe 32 is used to adapt the thread to the external threaded pipe 53. The opening of the connecting groove 33 facilitates the adaptation to the installation groove 42.

[0044] further;

[0045] like Figure 5 As shown, the installation components include;

[0046] The mounting groove 42 is opened at the top of the sealing tube 41. An outer ring 43 is fixedly installed on the outside of the sealing tube 41. The opening of the mounting groove 42 facilitates the fitting of the connecting ring 52. The sealing tube 41 provides a sealing effect, and the outer ring 43 can increase the sealing performance during the connection process.

[0047] Going a step further;

[0048] like Figure 5 As shown, the wiring mechanism 5 includes;

[0049] The outlet sleeve 51 is bolted to the top of the connecting pipe 31. An external threaded connector 53 is fixedly installed at the bottom of the outlet sleeve 51. A connecting ring 52 is fixedly installed on the outside of the outlet sleeve 51. The outlet sleeve 51 is used for internal and external connection through internal screws and other components. The connecting ring 52 is used for the adaptation operation during connection and sealing. The external threaded connector 53 can be directly threaded to the internal threaded connector 32, which can increase the connectivity and assist the sealing effect.

[0050] As mentioned above, when disassembly is required;

[0051] First, rotate the connecting ring 52 to drive the external threaded connector 53 to rotate, and then cause it to disengage from the internal threaded connector 32, thus terminating the threaded connection between the two. Then, pull the outlet sleeve 51 upwards directly. The outlet sleeve 51 directly drives the sealing tube 41 and the outer ring 43 on its outer side to move upwards together until the outlet sleeve 51 disengages from the inside of the connecting tube 31. At the same time, the sealing tube 41 disengages from the inside of the connecting tube 31 and the outer ring 43 disengages from the inside of the connecting groove 33, thus completing the disassembly operation.

[0052] At this point, it is necessary to further disassemble the sealing structure. The sealing tube 41 and the outer ring 43 are removed from the outside of the outlet sleeve 51, and then the connecting ring 52 is removed from the inside of the mounting groove 42. The sealing structure, that is, the entire sealing mechanism 4, is removed directly. After the disassembly is completed, the new sealing mechanism 4 can be taken out and replaced.

[0053] When replacing the new sealing mechanism 4, the installation can be completed by reversing the above disassembly method. Take out the new sealing mechanism 4 and put it on the outside of the outlet sleeve 51, and make the connecting ring 52 located inside the mounting groove 42. Then insert it into the inside of the connecting pipe 31 together until it contacts the internal threaded connector 32 and rotate it, so that the external threaded connector 53 and the internal threaded connector 32 are threadedly connected. At this time, the bottom end of the sealing pipe 41 is tightly connected to the top end of the internal threaded connector 32, and the outside of the sealing pipe 41 is tightly connected to the inner side wall of the connecting pipe 31. The outer ring 43 will be inserted into the inside of the connecting groove 33, and the connection between the sealing pipe 41 and the outer ring 43 will be pressed against the top end of the connecting pipe 31. Then, it is pressed by the above threaded connection. Finally, the connection is increased by the flange connection, thereby achieving a stable sealing effect.

[0054] It is worth explaining;

[0055] like Figure 3 As shown, the storage mechanism 2 includes;

[0056] The oil tank 21 is bolted to the bottom of the top cover 1. The top of the oil tank 21 is equipped with a sealing component. The oil tank 21 is used to store oil and three-phase windings, etc.

[0057] in;

[0058] like Figure 3 As shown, the hermetic assembly includes;

[0059] A groove 22 is formed on the top of the oil tank 21. A sealing ring 23 is installed inside the groove 22. The groove 22 is formed to accommodate the sealing ring 23. The sealing ring 23 increases the sealing between the oil tank 21 and the top cover 1. The sealing ring 23 is higher than the groove 22 so as to ensure the tightness of the connection and seal by pressing.

[0060] in addition;

[0061] like Figure 3 As shown, a pipe seat is fixedly installed on the top of the top cover 1. An oil pipe 6 is fixedly installed through both the pipe seat and the top of the top cover 1. The pipe seat facilitates the fixed penetration of the oil pipe 6 through the top cover 1, and then connects it with the oil conservator at the location to facilitate subsequent oil replenishment operations.
