Static contact assembly, high-speed grounding switch and HGIS (Hybrid Gas Insulated Switchgear) equipment

The invention belongs to the technical field of high-voltage switches, and particularly relates to a static contact assembly, a high-speed grounding switch and HGIS equipment. The static contact assembly comprises a static contact seat and a static contact, and is characterized in that the static contact comprises a contact finger sheet group formed by circumferentially stacking contact finger sheets, the outer side of the contact finger sheet group is provided with a clasping spring for clasping all the contact finger sheets together, one end, close to the moving contact, of the contact finger sheet group is provided with an arc striking ring, and the arc striking ring is provided with an arc striking groove. The static contact seat is provided with a shielding cover used for pressing the arc striking ring on the contact finger sheet group. The arc striking ring is arranged on the static contact, and the moving contact is firstly contacted with the arc striking ring in the contact process of the moving conta
