Description

Technical Field

[0001] This utility model relates to the field of equalizing ring technology, specifically a shielded equalizing ring. Background Technology

[0002] Shielded grading rings, also known as plate grading rings, are one of the two main structures used in high-voltage engineering to control electric fields, along with ring grading rings. While their designs and objectives overlap, there are also key differences. Although a shielded grading ring is not a completely enclosed cavity, its large metal plate surface can "capture" and "terminate" most of the electric field lines pointing towards its interior. This results in a very mild electric field environment in the areas "enclosed" by the ring (such as the metal caps of insulator heads, ball heads, and other sharp components).

[0003] Shielded equalizing rings are generally assembled from two semi-circular conical plates. Currently, shielded equalizing rings are generally connected only through the arc-shaped connecting plate in the middle, and some are also connected through the connecting plate on the outside. However, the stability and strength of the connection still need to be improved. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a shielded equalizing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shielded equalizing ring, comprising a first semi-circular conical plate and a second semi-circular conical plate, both of which are semi-circular. The first and second semi-circular conical plates are spliced ​​together to form a complete circular conical shell. A semi-circular groove is formed in the middle of both the first and second semi-circular conical plates. A first arc-shaped connecting plate is provided on the outer surface of the first semi-circular conical plate at the semi-circular groove, and a second arc-shaped connecting plate is provided on the outer surface of the second semi-circular conical plate at the semi-circular groove. The first and second arc-shaped connecting plates cooperate with each other and are secured by bolts. The first semi-circular conical plate is symmetrically provided with a first outer connecting plate on both sides of its outer surface, and the second semi-circular conical plate is symmetrically provided with a second outer connecting plate on both sides of its outer surface. The first and second outer connecting plates correspond one-to-one and are fastened together with bolts and nuts. The first inner connecting plate is provided on the inner surface of the first semi-circular conical plate at a position between the first arc-shaped connecting plate and the first outer connecting plate, and the second inner connecting plate is provided on the inner surface of the second semi-circular conical plate at a position between the second arc-shaped connecting plate and the second outer connecting plate. The first and second inner connecting plates correspond one-to-one and are fastened together with bolts and nuts.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The first semi-circular conical plate is connected to the second semi-circular conical plate via the first arc-shaped connecting plate and the first outer connecting plate on its outer surface. Furthermore, the inner side of the first semi-circular conical plate is connected to the second inner connecting plate of the second semi-circular conical plate via a first inner connecting plate that is offset from the first outer connecting plate. This greatly improves the connection strength between the two semi-circular conical plates, thereby ensuring the structural strength and stability of the shielded equalizing ring.
