Abstract
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.
