Description

Technical Field

[0001] The utility model relates to the technical field of equalizing pressure rings, in particular to an assembled equalizing pressure ring. Background Art

[0002] As a key component in high-voltage equipment, the grading ring plays a critical role in power systems. It is a circular ring-shaped component used to improve voltage distribution on insulators, particularly for AC voltages. Its unique structural design evenly distributes high voltage around the object, ensuring no potential difference between the various parts of the ring. This achieves voltage grading, significantly improving the safety and stability of high-voltage equipment operation.

[0003] Existing grading rings face numerous practical challenges. Their connections are often complex, and installation and removal are not only tedious but also time-consuming and labor-intensive. Workers often have to perform complex procedures to install the grading rings on high-voltage equipment. If a malfunction occurs, repair and replacement are extremely inconvenient, requiring significant human and material resources and potentially severely impacting the normal operation of the power system. Therefore, an assembled grading ring was proposed. Utility Model Content
