  • Apparatus for closing a ventilation opening in a housing of a switch gear and a switch gear comprising such an apparatus
    Patent number: 11757266
    Abstract: An apparatus for closing a ventilation opening in a housing of a switch gear in the event of a sudden increase in pressure caused by electric arcing. The apparatus includes a frame which is adapted to be coupled to the housing of the switch gear adjacent the opening, a flap pivotally mounted at the frame, the flap being adapted to be moved from an open position in which the flap overlaps the ventilation opening keeping a gap which allows an airflow through the opening, into a closed position, in which the flap fully covers the opening and blocks the air flow, spring elastic means which urge the flap into the open position, and a retaining element which is adapted to mechanically lock the flap in the closed position after pivoting the flap from the open position into the closed position.
