ABSTRACT:
Switchgear, such as gas-insulated, metal-encapsulated high-voltage switchgear, is accommodated in a container. The container has a side wall formed with an opening. An outwardly opening flap closes the opening in the normal situation. Upon a sudden pressure increase in the container, caused for instance by arcing, the flap is automatically opened and the container is vented. A linkage with a damper is connected to the flap for damping a motion of the flap into the open position.
