Description

Technical Field

[0001] This application relates to the field of base insulation cylinder technology, and more specifically, to a base insulation cylinder structure for a large-capacity hollow reactor. Background Technology

[0002] The base insulation cylinder plays a crucial role in electrical insulation and mechanical support in power systems, ensuring the safe operation and stability of power equipment. As part of the insulation structure, the base insulation cylinder ensures effective insulation between conductive components, which is essential for preventing leakage current and electric shock accidents, and helps improve the safety and reliability of the equipment. In addition, it also plays a mechanical support role, which can withstand the weight of the hollow reactor body and external mechanical stress, ensuring the stability and safety of power equipment.

[0003] Currently, conventional base insulation cylinders can meet the insulation requirements of most electrical equipment. However, for high-capacity or long-distance transported power equipment, the hollow structure of conventional base insulation cylinders is difficult to achieve the required mechanical strength. Therefore, they are prone to deformation under long-term working conditions, leading to oil leakage, reduced insulation performance, and potential safety hazards such as short circuits in power equipment.

[0004] To address the aforementioned issues, this application provides a base insulation cylinder structure for a large-capacity hollow reactor. Utility Model Content

On the outer side of the epoxy resin cylinder wall 1, a hexagonal rod 7 is fixedly connected to the center of the bottom of the epoxy resin plate 2. A base plate 8 is fixedly connected to the bottom of the hexagonal rod 7, and the base plate 8 is flush with the bottom of the epoxy resin cylinder wall 1. Six diverging arms 9 are evenly fixedly connected to the outer circumference of the hexagonal rod 7. Each diverging arm 9 is fixedly connected to a diagonal brace 10 at the end away from the hexagonal rod 7. One end of each diagonal brace 10 is fixedly connected to the bottom of the epoxy resin plate 2, and the other end of each diagonal brace 10 is fixedly connected to the inner wall of the epoxy resin cylinder wall 1. The epoxy resin cylinder wall 1 has a cylindrical hollow cylinder structure, and both the epoxy resin cylinder wall 1 and the epoxy resin plate 2 are made of epoxy glass fiber wound and cast.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The auxiliary components include a movable ring 11 that is slidably mounted on the outer wall of the middle part of the epoxy resin cylinder wall 1. A first stop 12 is provided above the movable ring 11, and a second stop 13 is provided below the movable ring 11. A connecting rod 14 is fixedly connected to one end face of the first stop 12 and the second stop 13. One end of each connecting rod 14 is fixedly connected to the outer surface of the movable ring 11. A limit structure is provided on the inner side of the movable ring 11, and a locking structure is provided on one side of the top of the movable ring 11. There are four first stops 12 and four second stops 13. Each first stop 12 and each second stop 13 is staggered with each first bolt hole 4 and each second bolt hole 6. The four first stops 12 are close to the bottom of the first outer ring 3, and the four second stops 13 are close to the top of the second outer ring 5.

[0033] The limiting structure includes an embedded groove 15 that is embedded in the inner side wall of the middle part of the movable ring 11. The inner wall of the embedded groove 15 is slidably sleeved with a limiting ring 16, while the limiting ring 16 is fixedly sleeved on the outer wall of the middle part of the epoxy resin cylinder wall 1.

[0034] The locking structure includes a fixed plate 17 fixedly installed on one side of the top of the movable ring 11. A rod 18 is slidably sleeved through the upper side of the fixed plate 17. A pull block 19 is fixedly connected to one end of the rod 18. A spring 20 is fixedly connected to the end face of the pull block 19 facing the rod 18. The spring 20 is located outside one side of the rod 18, and the end of the spring 20 facing away from the pull block 19 is fixedly connected to the outer surface of the fixed plate 17. A first insertion hole 21 is movably inserted into the side of the rod 18 facing away from the pull block 19. The first insertion hole 21 is opened at the outer end of the epoxy resin cylinder wall 1. The locking structure also includes two second insertion holes 22 opened at the outer end of the epoxy resin cylinder wall 1. The two second insertion holes 22 are respectively located on both sides of the horizontal position of the first insertion hole 21. With the setting of the two second insertion holes 22, the positioning operation after the movable ring 11 is rotated in both directions can be facilitated, thereby improving the flexibility of use.

[0035] The implementation principle of this embodiment is as follows: During use, the entire assembly is in a fully assembled state. Each first bolt hole 4 on the first outer ring 3 allows for the fixed assembly of the base insulating cylinder with the supported electrical equipment via external bolts. Similarly, each second bolt hole 6 on the second outer ring 5 allows for the fixed assembly of the base insulating cylinder on the plane of its intended use via external bolts. After the fixed assembly is completed, the pull block 19 can be manually pulled out, causing the spring 20 to stretch, thereby indirectly disengaging one end of the insertion rod 18 from the insertion hole 21. Then, the movable ring 11 is... The outer wall of the epoxy resin cylinder 1 is rotated (clockwise or counterclockwise) so that the insertion rod 18 corresponds to one of the insertion holes 22 before insertion. At this time, each first stop 12 and second stop 13 is driven by the movable ring 11 to move to the port of each first bolt hole 4 and second bolt hole 6, thereby achieving the contact restriction of each installed bolt part and preventing loosening due to long-term use. During the passive rotation of the movable ring 11, the rotational bearing and limiting work of itself is achieved through the rotational cooperation of the embedded ring groove 15 and the limiting ring 16.

[0036] During the process of supporting electrical equipment, the overall base insulating cylinder effectively ensures its own support stability performance by limiting the materials of the epoxy resin cylinder wall 1 and epoxy resin board 2, as well as the auxiliary support of the hexagonal rod 7, chassis 8 and each diverging arm 9 and diagonal brace arm 10 on the inner side of the two. Among them, after the epoxy resin cylinder wall 1 and epoxy resin board 2 are produced, their inner and outer surfaces need to be dried and then coated with two coats of epoxy varnish for moisture protection.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
