Abstract
Description
Technical Field
[0001] This utility model relates to the field of equalizing rings, and more particularly to a high-stability equalizing ring. Background Technology
[0002] The main function of voltage equalization rings is in ultra-high voltage transmission systems. They can effectively ensure the stability and safety of transmission lines operating in high-voltage environments. Through the design of voltage equalization rings, the voltage distribution in the transmission line can be made more uniform, reducing the non-uniformity of electric field intensity, thereby reducing the possibility of partial discharge and corona loss. In addition, voltage equalization rings also help improve transmission efficiency, reduce energy loss, and ensure efficient and reliable power transmission.
[0003] A Chinese patent document CN201921573814.9 discloses a split-type equalizing ring, comprising a bottom equalizing ring, a first spiral hole on the upper surface of the bottom equalizing ring, an equalizing inclined rod movably installed inside the first spiral hole, a middle equalizing ring movably installed at the top of the equalizing inclined rod, a second spiral hole at the bottom surface of the middle equalizing ring, a third spiral hole at the top surface of the middle equalizing ring, an equalizing vertical rod movably installed inside the third spiral hole, a top equalizing ring movably installed at the top of the equalizing vertical rod, and a fourth spiral hole at the bottom surface of the top equalizing ring. This split-type equalizing ring uses an assembly structure, allowing the large equalizing ring to be disassembled into smaller parts during transportation, reducing its size and facilitating transport, greatly increasing work efficiency and extending service life. Furthermore, the equalizing ring and the equalizing rod are connected by threads, preventing damage to the equalizing ring during installation and greatly enhancing the practicality of the device.
[0004] However, the above-mentioned patent has certain defects in use. The large ring at the bottom of the split equalizing ring is usually larger in diameter than the other rings. It needs to withstand a large weight during installation. It is only connected by threads, and there is a risk of falling off or deforming in harsh environments, which affects the equalizing effect.
[0005] To address these issues, a highly stable equalizing ring is proposed. Utility Model Content

[0047] The principle of this utility model is as follows: When the equalizing ring encounters extreme weather, the rivets 12 at both ends of the movable rod 13 are slightly displaced in the displacement grooves 11 in the upper connection 17 and the lower connection 10. At the same time, the movable rod 13 connected in the movable groove 23 is supported by the reinforcing ribs 14, which significantly reduces the friction effect between the middle ring 2 and the lower ring 3 caused by extreme weather, ensuring the stability of the overall structure of the equalizing ring and improving the reliability of the system under extreme conditions.
