Description

Technical Field

[0001] This utility model relates to the field of equalizing ring technology, specifically an open-type equalizing ring structure. Background Technology

[0002] Equalizing rings are mainly suitable for AC voltage applications, and their function is to distribute high voltage evenly around an object to ensure that there is no potential difference between different parts of the ring, thereby achieving the effect of equalizing voltage. Open-type equalizing rings are structures with discharge breaks on the ring body. A significant difference between open-type and closed-type rings is that the discharge of open-type rings occurs in the open direction, while the discharge of closed-type rings has no obvious pattern.

[0003] However, existing open-type equalizing ring structures have the following problems during use: Since equalizing rings are generally only fixed by bolts, the connection stability is insufficient, and the bolts are exposed externally, which can loosen and rust after prolonged use, affecting the installation stability of the equalizing ring. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content
