Abstract: A pressure release device includes a movable pressure release wall that can be moved relative to a pressure release opening. The pressure release wall, by virtue of its position relative to the pressure release opening, controls the passability of the opening. A detent stop is arranged in a path of movement of the pressure release wall.

Abstract: A drive unit for driving switching contacts of a high-voltage circuit breaker includes an operating element, and a plurality of actuating elements for actuating the switching contacts, at least two of which are disposed at a distance from one another relative to an axis or shaft. A mechanism or lever mechanism transfers a movement of the operating element into corresponding movements of the actuating elements. The mechanism includes at least one shaft, rotatably mounted on the axis, for transferring the movement of the operating element into the corresponding movement of at least one actuating element which is disposed at a distance from the operating element along the axis. The drive unit has a compensation coupling device for compensating for a delay in the transfer of movement between at least two of the actuating elements disposed at a distance from one another relative to the axis.

Abstract: A switchgear cabinet is equipped with a pressure relief channel for discharging a fluid stream. A diffuser is arranged in the pressure relief channel. The diffuser has a mechanically stabilizing base plate with multiple first openings, which are covered by a meshwork with multiple second openings.

Abstract: A switching device has an encapsulation housing and lashing points. The lashing points are arranged in such a manner that a center of gravity of the switching device lies below the lashing points in a lashing direction.

Abstract: A switching contact drive device contains a transmission with an energy store. The energy store is enclosed in a housing. The housing guides a relative movement, particularly a deformation of the energy store. The switching contract drive device is provided for driving an electrical switching device such as a circuit breaker.
