This cell () comprises a pot shell () having two longitudinal sides () which are symmetrical in relation to a longitudinal median plane (P) of the electrolytic cell (), an anode assembly which can only move in vertical translation with respect to the pot shell (), the anode assembly comprising an anode block () and a transverse anode support () extending at right angles to the longitudinal sides () of the pot shell (), from which support the anode block () is suspended. The anode support () comprises two connecting portions () from which electrolysis current is supplied to the anode support (), and the cell () comprises electrical connection conductors () electrically connected to the two connecting portions () of the anode support (), the two connecting portions () being located on either side of the plane (P).

Electrolytic cell intended for the production of aluminium and electrolytic smelter comprising this cell

An electrolysis device comprising a pot shell () and an inner lining () defining an opening () through which an anode block () suspended from an anode support () forming an anode assembly () moves vertically by means of an anode receiver (), said anode receiver being placed outside a space defined by the top of said anode block (), said anode receiver comprising an anode contact surface () working in conjunction with the anode support () to establish therewith electrical contact and mechanical contact to moving the anode assembly () vertically. An anode assembly (). An electrolytic cell and an electrolysis installation comprising such an anode assembly.

Electrolytic device and anode assembly intended for the production of aluminium, electrolytic cell and apparatus comprising such a device

The electrical connection device connecting the cells in series comprises:

Electrical connection device, for connecting between two successive cells of a series of cells for the production of aluminium

The invention relates to a device () and a method for short-circuiting a specified electrolysis in a row of electrolysis cells intended for the production of aluminum. This device includes a bridging member () including at least two opposite contact arms and at least one bridging conductor electrically that electrically connects the contact arms. The contact arms are shaped like a wedge. The device further includes a clasping member () including a frame and a least two opposite thrust members. The clasping member () is fit to embrace the bridging member () so that each thrust member bears on each contact arm and so that, upon moving the contact arms with respect to the clasping member, each thrust member urges the corresponding contact arm towards the conductors () inserted between the contact arms, so as to create and secure a short-circuit. The invention makes it possible to short-circuit electrolysis cells with increased amperages.
