Description

Technical Field

[0001] This utility model belongs to the technical field of power transformers, specifically relating to a novel sealing ring limiting resin sleeve. Background Technology

[0002] New-type transformer bushings, also known as transformer bushings, are an important component of power transformers. They are mainly used to connect the high-voltage windings inside the transformer to the external circuit, while ensuring insulation and sealing performance. With the development of power systems, transformer bushings are constantly being innovated in terms of materials, design, and manufacturing processes to improve their electrical performance, mechanical strength, and durability.

[0003] However, the existing new type of sealing ring limiting resin sleeve has an excessive installation torque, which causes the sealing ring to fail due to over-compression. Its traditional pressure plate structure is not an integrated installation, which is very unfavorable for improving the dry arc size, improving the electrical performance of the sleeve and ensuring the continuity of power transmission.

[0004] This utility model addresses the aforementioned problems by providing a novel sealing ring limiting resin sleeve that facilitates structural installation and disassembly. Utility Model Content

[0005] The purpose of this utility model is to provide a novel sealing ring limiting resin sleeve to solve the problems mentioned in the background art, such as excessive installation torque, over-compression of the sealing ring causing sealing ring failure, and the traditional pressure plate structure being non-integrated, which is very detrimental to improving the dry arc size, improving the electrical performance of the sleeve, and ensuring the continuity of power transmission.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel sealing ring limiting resin sleeve, comprising a conductive rod and a hot-dip galvanized bolt connected to the conductive rod near its end; Epoxy resin is applied to the outer side of the conductive rod, and a pressure plate is positioned above the epoxy resin. The pressure plate has two types of reinforcing ribs: a flat surface and two surrounding reinforcing ribs, and a top annular reinforcing rib. An anti-deviation annular protrusion is provided at the lower part of the epoxy resin flange. A rectangular sealing ring and a cover sealing groove are provided on the lower side of the resin flange. The rectangular sealing ring is installed inside the sealing groove. Eight protrusions are provided on the bottom side of the pressure plate. The protrusions are designed to fit the dimensions of the rectangular sealing ring, the resin flange, and the pressure plate after compression, and are symmetrically distributed. The pressure plate matches the slot size of the cover, ensuring that when the rectangular sealing ring is fully compressed, the eight protrusions of the pressure plate contact the cover, indicating that the seal is fully compressed.

[0007] Preferably, a stainless steel bolt is installed near the bottom of the conductive rod, and the stainless steel bolt is made of stainless steel.

[0008] Preferably, the hot-dip galvanized bolts are connected to the conductive rod via threads, and the conductive rod plate surface is chamfered to increase the arc distance and improve electrical performance.

[0009] Preferably, the pressure plate is an integral structure. The integral structure of the pressure plate reduces the thickness and shortens the welding and mounting bolts.

[0010] Preferably, the pressure plate is provided with welded screws and elongated holes near its four corners, and the elongated holes for mounting the pressure plate can meet the needs of different installation sizes.

[0011] Compared with the prior art, this utility model provides a novel sealing ring limiting resin sleeve, which has the following beneficial effects: In the novel sealing ring limiting resin bushing, epoxy resin is provided on the outer side of the conductive rod, and a pressure plate is provided on the upper side of the epoxy resin. The pressure plate is provided with two types of reinforcing ribs: a flat surface and surrounding reinforcing ribs, and a top annular reinforcing rib. The lower part of the epoxy resin flange is provided with an anti-deviation annular protrusion. A rectangular sealing ring and a sealing groove for the tank cover are provided on the lower side of the resin flange. The rectangular sealing ring is installed in the sealing groove. The bottom side of the pressure plate is provided with protrusions. The protrusions are designed according to the dimensions of the rectangular sealing ring, the resin flange, and the pressure plate, and their compressed dimensions are designed. The eight protrusions are symmetrically distributed. The dimensions of the pressure plate and the tank cover groove match to ensure that when the rectangular sealing ring is pressed into place, the eight protrusions of the pressure plate contact the tank cover, indicating that the seal is fully compressed. The reinforcing ribs can improve the mechanical strength of the pressure plate limiting. This invention can reduce the height of the mounting bolts, increase the arc dimension, improve the electrical performance of the bushing, ensure the continuity of power transmission, help extend the service life of the transformer bushing and the entire transformer equipment, and reduce the maintenance and replacement costs of the equipment.

[0018] 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.

[0019] This utility model provides, for example Figure 1-5 As shown, a novel sealing ring limiting resin sleeve includes a conductive rod 2 and a hot-dip galvanized bolt 7 connected to the conductive rod 2 near its end. A novel sealing ring limiting resin sleeve includes a conductive rod 2 and a hot-dip galvanized bolt 7 connected to the conductive rod 2 near its end. An epoxy resin 5 is installed on the outer side of the conductive rod 2, and a pressure plate 6 is installed on the upper side of the epoxy resin 5. The pressure plate 6 has two types of reinforcing ribs 9: a flat surface, surrounding reinforcing ribs, and a top annular reinforcing rib. The lower part of the resin flange of the epoxy resin 5 has an anti-deviation annular protrusion. The lower side of the resin flange has a rectangular sealing ring 4 and a sealing groove for the cover 3. The rectangular sealing ring 4 is installed in the sealing groove. The bottom side of the pressure plate 6 has protrusions 8. The protrusions 8 are designed according to the dimensions of the rectangular sealing ring 4, the resin flange, and the pressure plate 6. The eight protrusions 8 are symmetrically distributed. The groove dimensions of the pressure plate 6 and the cover 3 match to ensure that when the rectangular sealing ring 4 is pressed in place, the eight protrusions 8 of the pressure plate contact the cover 3, indicating that the seal is fully compressed. The reinforcing ribs 9 can improve the mechanical strength of the pressure plate 6 in limiting the position. This invention can reduce the height of the mounting bolts, increase the arc dimension, improve the electrical performance of the bushing, ensure the continuity of power transmission, help extend the service life of the transformer bushing and the entire transformer equipment, and reduce the maintenance and replacement costs of the equipment.

[0020] like Figure 1 As shown, a stainless steel bolt 1 is installed near the bottom of the conductive rod 2. The stainless steel bolt 1 is made of stainless steel. A hot-dip galvanized bolt 7 is connected to the conductive rod 2 by threads. The hot-dip galvanized bolt 7 is made of hot-dip galvanized material. The hot-dip galvanized bolt 7 and the stainless steel bolt 1 are used to connect and fasten the rod.

[0021] like Figure 1As shown, the hot-dip galvanized bolt 7 is connected to the conductive rod 2 by threads. The conductive rod 2 has a chamfered plate surface, which can increase the arc distance and improve electrical performance. The conductive rod 2 serves as a current transmission channel, leading the high voltage or large current of the transformer's internal windings to the external transmission line, or conversely, introducing the electrical energy of the external circuit into the transformer. The conductive rod 2 is usually made of high-strength conductive materials (such as copper or aluminum), which not only need to withstand the electrodynamic force when the current passes through, but also need to support the insulating components inside the bushing (such as insulating oil, capacitor core, etc.) to ensure the stability of the overall bushing structure.

[0022] like Figure 1 As shown, the pressure plate 6 is an integral structure. The integral structure of the pressure plate reduces the thickness and shortens the welding installation bolts. The pressure plate 6 has welding screws near its four corners. The integral pressure plate installation can reduce the height of the installation bolts, increase the arc size, improve the electrical performance of the bushing, and ensure the continuity of power transmission. The pressure plate 6 has welding screws and elongated holes near its four corners. The elongated holes of the pressure plate installation holes can meet the needs of different installation sizes.

[0023] like Figure 1 As shown, epoxy resin 5, as an important insulating and structural material, plays a role in multiple aspects such as electrical insulation, mechanical support, sealing protection, and thermal stability management.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
