Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to an oil replenishing assembly for a transformer. Background Art

[0002] When adding insulating oil to traditional transformers, the box or cover needs to be opened to add oil, which may cause the insulating oil to come into contact with the external environment, thereby introducing impurities and moisture, affecting the insulation performance and safe operation of the transformer. In addition, frequent opening and closing operations may also reduce the sealing performance of the transformer, increasing maintenance costs and safety risks. Utility Model Content

[0003] The problem to be solved by the present application is that when the insulating oil of the existing transformer is replenished, the box body or the box cover needs to be opened, which not only easily introduces impurities and moisture into the transformer, but also easily reduces the sealing performance of the transformer.

[0004] In order to solve the above technical problems, the present application provides an oil replenishing assembly for a transformer, the oil replenishing assembly comprising a tube body for containing oil, joints for achieving connection and reducing diameter are symmetrically arranged at both ends of the tube body, a shielding member for alternately sealing the two joints is arranged along the axial direction inside the tube body, and a driving member for driving the shielding member to perform alternating sealing operations is vertically arranged on the upper part of the side wall of the tube body, and a transmission member with a reversing transmission operation is arranged between the driving member and the shielding member.

[0005] Since the oil replenishing assembly of the present application is designed with a shielding member, a driving member and a transmission member, the insulating oil replenishing operation of the transformer can be realized in a closed state without opening the box body or the box cover through the combination of the shielding member, the driving member and the transmission member, thereby solving the problem that the transformer in the prior art needs to open the box body or the box cover when replenishing the insulating oil, which not only easily introduces impurities and moisture into the transformer, but also easily reduces the sealing performance of the transformer.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0013] The present application relates to an oil replenishment assembly 1 for a transformer, such as Figure 1-5 As shown, the oil replenishing assembly 1 is vertically arranged on the upper part of the transformer box cover and is connected with the inside of the transformer box. The oil replenishing assembly 1 includes a tube body 4 for containing oil, and joints 3 for achieving communication and reducing diameter are symmetrically arranged at both ends of the tube body 4. The joint 3 at the top of the tube body 4 is sleeved with a cap 2 for sealing and shielding, and inside the tube body 4, a shielding member 6 for alternately sealing the two joints 3 is arranged along its axial direction, and a driving member 5 for driving the shielding member 6 for alternately sealing operation is arranged vertically on the upper part of the side wall of the tube body 4, and a transmission member 7 with a reversing transmission operation is also arranged between the driving member 5 and the shielding member 6.

[0014] The shielding member 6 includes an end cover 17, a connecting rod 8, and a frame 9. The frame 9 is fixedly arranged on the upper part of the inner wall on one side of the axial direction of the tube body 4. The end cover 17 for sealing the joint 3 is arranged coaxially inside the tube body 4, and the connecting rod 8 for supporting and guiding the end cover 17 is arranged on the upper part of the tube body 4. With the help of the arrangement of the connecting rod 8, the two end covers 17 can move in the same direction in a linked manner.

[0015] The driving member 5 includes a base 15, a handwheel 16, and a screw 14. The base 15 is fixedly arranged on one side of the outside of the cylinder. A handwheel 16 connected to the base 15 and capable of rotating freely is arranged at one end of the base 15, and a screw 14 threadedly connected to the handwheel 16 is arranged at the axial center position inside the base 15.

[0016] The transmission member 7 includes a block 18, a connecting plate 10, a tension spring 12, a compression spring 11, and a lever 13. The block 18 is arranged at the center of the upper part of the connecting rod 8. The lever 13 is arranged directly below the screw 14 and one end is connected to it. In order to achieve the reciprocating sliding operation of the connecting rod 8 by rotating the lever 13, a connecting plate 10 for connecting the two is arranged between the block 18 and the lever 13. In order to make the rotation of the lever 13 and the connecting plate 10 smoother, a tension spring 12 for pulling the connecting plate 10 is arranged on the upper part of the frame 9, and a compression spring 11 abutting against the frame 9 and the block 18 respectively is arranged on the upper part of the connecting rod 8.

[0017] During use, when the transformer needs to be refilled with oil, the end cap 17 at the lower part of the tube body 4 is sealed against the joint 3, and a gap is left between the end cap 17 at the upper part of the tube body 4 and the joint 3. At this moment, the end cap is opened, and the insulating oil to be refilled can be poured along the joint 3. After the insulating oil fills the inside of the tube body 4, the hand wheel 16 is manually turned, and the screw rod 14 is driven to move outward along the base 15, thereby converting the circumferential rotation of the hand wheel 16 into a linear motion of the screw rod 14, so that the screw rod 14 pulls the lever 13 to move The side wall of the tube body 4 moves, thereby stretching the tension spring 12, and the other end of the pull rod 13 pulls the connecting plate 10 to rotate around the block 18, and then the block 18 drives the connecting rod 8 to move upward, so that the end cover 17 at the upper end of the connecting rod 8 closes the oil inlet joint 3, and the end cover 17 at the lower end of the connecting rod 8 is separated from the joint 3, so that the insulating oil inside the tube body 4 can flow into the transformer in a closed state, and according to the amount of oil replenishment required, the above oil replenishment steps are repeated to realize the oil replenishment operation of the transformer in a sealed state.
