Document Type and Number:
WIPO Patent Application WO/2022/027182
Kind Code:
A1
Abstract:
A grounding structure (60) comprises a grounding guide (610) defining a guiding hole (617) and a grounding support (620) fixed on the grounding guide (610) and defining a cavity (622) for accommodating a grounding contact (640). The grounding contact (640) is arranged in the cavity (622) and protrudes through the guiding hole (617) on the grounding guide (610). The grounding contact (640) is moveable along the wall of the cavity (622) by a grounding spring (630) accommodated in the cavity (622) to realize the adaptive adjustment of the installation position. The grounding structure (60) can be pre-assembled in an accurate and efficient way to avoid the components therein damaging, thereby improving the reliability and safety of the grounding structure (60) and the gas-insulated equipment in which the grounding structure is used.
