Abstract
A high-speed grounding apparatus for metal encapsulated high-voltage switching installations embodying a grounding bolt which, by igniting a propellent charge, can be forwardly shifted out of its rest position into its grounding or earthing position for electrically connecting the capsule with a conductor encapsulated therein. An ignition device is provided for the propellent charge, this ignition device being triggered by an increase in pressure in the switching installation.
