Abstract: The aim of the invention is to prevent an unwanted conduction of a flow of gas inside a channel that connects an inner space of an enclosed switchgear (1) to another space. To this end, the channel is closed by means of a closing mechanism according to an increase in pressure in the inner space.

Abstract: The invention relates to a bushing (1) for supporting electric conductors. Said bushing contains a flange section (2), a corrugated section (3), which projects above the flange section in the longitudinal direction of the electric conductor, in addition to at least one retaining section (4), which has bushing orifices (7) that are open on both sides for receiving busbars. The aim of the invention is to reduce the production costs and simplify the assembly of a bushing of this type. To achieve this, the bushing (1) is configured in one-piece, each retaining section (4) being solely supported on the flange section (2) by means of the corrugated section (3).

Abstract: The invention relates to an electrical installation, especially a medium-voltage switchgear, comprising at least one encapsulated function module (FM), a decompression channel (DK) which is connected to said function module, and at least one inflow opening (EO . . . ) which connects the function module (FM) to the decompression channel (DK). The covering surface (DF 1,2,3) of the decompression channel (DK), opposite the inflow opening (EO . . . ), comprises at least one partial region which is obliquely oriented in relation to the inflow direction. Hot gases and high pressures produced during an accidental arc can thus be evacuated from the installation, without any risk to humans and buildings. Pressure channels are used, inter alia, in installations used in relation to medium-voltage technique for providing and distributing energy.

Abstract: An electrical switchgear (ES) comprising at least one function module (FM, FM . . . ) having an encapsulated housing, and a decompression channel (DK) which is connected to the housing. Said decompression channel (DK) comprises a ventilation device (LV, LV . . . ) in at least one of its generated surfaces, said device having two wall-type ventilation elements (LE 1,2) which are successively arranged at a distance from each other and are provided with ventilation openings. One ventilation element (LE 1) is connected to the generated surface of the decompression channel (DK) in a fixed manner, and the other ventilation element (LE 2) can be moved in a guided manner against the fixed ventilation element (LE 1). The moveable ventilation element (LE 2) can be linearly displaced inside a guiding frame (FR) and the ventilation openings of the ventilation elements (LE 1,2) are staggered in relation to each other.
