[0002] At present, some models of main transformers use rectangular rubber rings for sealing in the sealing design of flange connection surfaces such as gas relays, heat sinks, and connecting pipes. Since the compression of the rectangular rubber ring is uncontrollable and the processing quality of the sealing surface, especially the rubber ring groove, varies from manufacturer to manufacturer, the flange connection surface is poorly sealed and oil leakage occurs from time to time. On the one hand, it affects the safe and stable operation of the main transformer, and on the other hand, it increases the cost of manual operation and maintenance.

[0003] At present, all newly designed and put into operation equipment are required to use circular rubber rings for sealing. The circular rubber rings are easier to control the compression and have better sealing effect. However, for the flange connection surface of the existing equipment using rectangular rubber rings, there is no more effective technical solution to enhance its sealing performance. It is necessary to process the rubber ring groove of the connection surface or replace the new flange connection surface. The existing problems are:

[0004] 1. The main transformer equipment currently in operation is often difficult to shut down or the shutdown period is short. The sealing surface processing and modification takes a long time and is difficult to carry out.

[0005] 2. Transformers of different models and designs have different structures, and there is no universal or unified technical solution for sealing surface modification.

After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0042] Please refer to Figure 1 The embodiment of the present invention provides a main transformer equipment rubber ring conversion device, which is specially designed for use in the main transformer equipment and aims to solve many problems existing when the main transformer equipment originally uses a rectangular rubber ring 1 for sealing. The device is composed of two major parts: a connecting plate 2 and a circular rubber ring 3, wherein the rectangular rubber ring 1, the connecting plate 2 and the circular rubber ring 3 are cleverly connected and arranged in sequence to realize the conversion of the sealing method of the main transformer equipment from the rectangular rubber ring 1 to the circular rubber ring 3.

[0043] Specifically, the core of the embodiment of the present invention is to use the connecting plate 2 as an intermediary to cleverly convert the main transformer equipment that originally uses a rectangular rubber ring 1 for sealing into a circular rubber ring 3 for sealing. This conversion process does not require any modification to the processing design of the flange connection surface, which greatly maintains the original structure and functional integrity of the equipment.

[0044] By introducing the connecting plate 2 and the circular rubber ring 3, the embodiment of the present invention effectively solves the deficiency of the rectangular rubber ring 1 in controlling the compression amount. Due to its shape characteristics, the rectangular rubber ring 1 is often difficult to accurately control its compression amount, resulting in poor sealing effect, frequent oil leakage and other problems. However, the circular rubber ring 3 is easy to compress due to its regular shape and the compression amount is controllable, thereby significantly improving the sealing quality and effectively improving the problem of poor sealing.

[0045] In addition, the embodiments of the present invention also bring significant economic benefits. By improving the sealing quality, the present invention effectively reduces the failure rate of the main transformer equipment, improves its operating stability, and thus reduces the operation and maintenance costs. This innovative achievement not only solves the pain points in the prior art, but also provides new ideas and solutions for the upgrading and transformation of the main transformer equipment, and has broad market application prospects and far-reaching industry impact.

[0046] To sum up, the main transformer equipment rubber ring conversion device proposed in the embodiment of the present invention, by introducing the connecting plate 2 and the circular rubber ring 3, realizes the conversion of the sealing method from the rectangular rubber ring 1 to the circular rubber ring 3 without changing the processing design of the flange connection surface. It not only improves the sealing quality and reduces the operation and maintenance cost, but also provides a strong guarantee for the stable operation of the main transformer equipment, and has extremely high practical value and innovation.

[0047] Please refer to Figure 2-3 In a specific embodiment of the present invention, the connection structure between the rectangular rubber ring 1 and the connecting plate 2 is designed and optimized in detail. Specifically, a first rubber ring groove 4 is provided at a specific position of the rectangular rubber ring 1 in this embodiment, and this design is intended to provide a stable connection interface so as to achieve accurate and firm assembly with the connecting plate 2.

[0048] Furthermore, the connection plate 2 is designed with a first connection protrusion 5 on the surface in contact with the rectangular rubber ring 1, which is perfectly matched with the first rubber ring groove 4. The shape, size and position of the first connection protrusion 5 are carefully calculated and designed to ensure that it can be accurately embedded in the first rubber ring groove 4 of the rectangular rubber ring 1, thereby achieving a tight connection between the two.

[0049] Through such a design, the present invention not only enhances the connection strength between the rectangular rubber ring 1 and the connecting plate 2, but also improves the stability and reliability of the connection. In addition, this matching connection method also helps to ensure the accurate positioning of the rectangular rubber ring 1 during the conversion process, providing a solid foundation for the subsequent installation and use of the circular rubber ring 3.

[0050] In summary, this embodiment realizes the precise connection between the rectangular rubber ring 1 and the connecting plate 2 by providing the first rubber ring groove 4 on the rectangular rubber ring 1 and providing the first connecting protrusion 5 matching the first rubber ring groove 4 on the connecting plate 2, which provides a reliable guarantee for the subsequent introduction of the circular rubber ring 3 and the conversion of the sealing method. This design not only reflects the consideration and innovation of the present invention in details, but also further demonstrates its significant advantages in improving the sealing performance and operation stability of the main transformer equipment.

[0051] Please refer to Figure 4-6In another specific embodiment of the present invention, the connection structure between the connecting plate 2 and the circular rubber ring 3 is further refined to ensure that the connection between the two is both stable and efficient.

[0052] Specifically, in this embodiment, a second rubber ring groove 6 is cleverly designed on the other surface of the connecting plate 2 that contacts the circular rubber ring 3. This design is intended to provide a precise assembly interface so that the circular rubber ring 3 can be accurately positioned and tightly connected to the connecting plate 2.

[0053] At the same time, the circular rubber ring 3 is also designed with a second connection protrusion 7 that perfectly matches the second rubber ring groove 6 on the surface in contact with the connecting plate 2. The shape, size and position of the second connection protrusion 7 are precisely calculated and designed to ensure that it can be fully embedded in the second rubber ring groove 6 of the connecting plate 2, thereby achieving a firm connection between the two.

[0054] Through such a design, the present invention not only significantly enhances the connection strength between the connecting plate 2 and the circular rubber ring 3, but also improves the stability and durability of the connection. In addition, this matching connection method also helps to ensure the accurate positioning of the circular rubber ring 3 during the assembly process, thereby avoiding the problem of reduced sealing performance or leakage caused by improper assembly.

[0055] It is worth noting that the design of the second rubber ring groove 6 and the second connecting protrusion 7 in this embodiment corresponds to the design of the first rubber ring groove 4 on the rectangular rubber ring 1 and the first connecting protrusion 5 on the connecting plate 2 described previously, and together constitute a complete and efficient sealing conversion system. This system not only realizes a smooth transition from the rectangular rubber ring 1 to the circular rubber ring 3, but also significantly improves the sealing performance and operating stability of the main transformer equipment.

[0056] To sum up, this embodiment further refines the connection structure between the connecting plate 2 and the circular rubber ring 3 by providing a second rubber ring groove 6 on the connecting plate 2 and a second connecting protrusion 7 on the circular rubber ring 3 that cooperates with the second rubber ring groove 6, thereby providing a strong guarantee for improving the sealing performance and operating stability of the main transformer equipment.

[0057] In a specific and optimized implementation of this embodiment, the circular rubber ring 3 is designed as a cylindrical rubber ring. This design choice not only meets the basic shape requirements of the seal, but also shows its unique advantages in many aspects.

[0058] First, the cylindrical rubber ring has a regular geometric shape, which allows it to maintain high stability and consistency during installation and use. This shape characteristic helps ensure that the rubber ring can deform evenly when subjected to pressure, thereby providing a more reliable sealing effect.

[0059] Secondly, the manufacturing process of cylindrical rubber rings is relatively mature and low-cost, which helps to reduce the production cost of the entire conversion device and improve its market competitiveness. At the same time, cylindrical rubber rings also have good durability and corrosion resistance, and can maintain a long service life in harsh working environments.

[0060] In addition, the cylindrical rubber ring is more tightly and stably matched with the second rubber ring groove 6 on the connecting plate 2. This tight match helps to reduce the risk of leakage and improve the sealing performance.

[0061] In summary, this embodiment, by designing the circular rubber ring 3 as a cylindrical rubber ring, not only improves the stability and consistency of the seal, but also reduces the production cost and enhances the durability and corrosion resistance.

[0062] In one implementation of this embodiment, a design of multiple connecting plates 2 is introduced, and the sizes and / or shapes of the first connecting protrusions 5 provided on the surfaces of these connecting plates 2 are different. This design is intended to adapt to rectangular rubber rings 1 of different specifications, models or application scenarios, thereby ensuring the wide applicability and high efficiency of the rubber ring conversion device of the main transformer equipment.

[0063] Specifically, the first connecting protrusion 5 of each connecting plate 2 is specially designed according to the size and shape of the first rubber ring groove 4 of the rectangular rubber ring 1 to be adapted. This means that for rectangular rubber rings 1 of different sizes or shapes, a connecting plate 2 with a first connecting protrusion 5 of corresponding size and shape can be selected for connection to ensure that the two can achieve accurate and firm fit.

[0064] This design not only improves the flexibility and adaptability of the main transformer equipment rubber ring conversion device, but also significantly reduces the customization cost of the conversion device caused by different specifications of the rectangular rubber ring 1. In addition, since each connecting plate 2 is specially designed according to actual needs, they can transmit and disperse pressure more effectively, thereby improving sealing performance and reducing leakage risks.

[0065] It is worth noting that although the present embodiment mentions the design of multiple connection plates 2, it does not mean that each connection plate 2 needs to be used in the conversion process of the same main transformer device. On the contrary, these connection plates 2 can be selected and combined according to actual needs to meet the conversion requirements of different main transformer devices.

[0066] In summary, this embodiment significantly improves the flexibility and adaptability of the main transformer rubber ring conversion device by introducing multiple connecting plates 2 with first connecting protrusions 5 of different sizes and / or shapes. This design not only reduces the customization cost, but also improves the sealing performance and reliability, providing a better solution for the upgrading and transformation of the main transformer equipment.

[0067] Although the terms such as connecting plate and circular rubber ring are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0068] An embodiment of the present invention provides a main transformer equipment rubber ring conversion device, which, through a connecting plate and a circular rubber ring, can, under the intermediary effect of the connecting plate, realize the conversion of the main transformer equipment from an original rectangular rubber ring with uncontrollable compression to a circular rubber ring seal with controllable compression without changing the processing design of the flange connection surface, thereby improving the rubber ring sealing quality, effectively improving the problem of poor sealing, improving the operating stability of the main transformer equipment, and reducing the operation and maintenance costs. It has a very broad prospect for promotion and application.

[0069] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
