    The invention relates to a device for reducing magnetic disturbances in a series of very high intensity electrolysis cells. The device is characterized by the supply of an anode bus bar both through its two ends and through at least one central riser supplied from upstream cathode outputs and by a branch on the downstream cathode output rods of the preceding cell. Application is to the production of aluminum by electrolysis of alumina in molten cryolite.

    The invention relates to the production of aluminum by the electrolysis of molten cryolite salts, mainly in electrolyzers with their transverse position in the electrolysis housing. The known busbar of an aluminum electrolysis cell is located transversely in the electrolysis housing, in which the anodic distribution busbars are connected by four racks located along the inlet side of the cathode sheath to the cathode tire packs of the inlet and outlet sides of the cathode sheath, and 1/4 current of series 1. Also known is the busbar of an electrolyzer located transversely in the electrolysis building, in which the anodic distribution busbars are connected at the ends with four racks, and in the middle with one com mounted at the front .storony cathode casing. 1/2 of the series current is supplied to it, and 1/8 2 .. to each of the four racks. The disadvantage of these busbars is that the current distribution is. It does not take into account the effect of the magnetized ferromagnetic structures of the cathode sheath on the distribution of the magnetic field and electrodynamic forces in the molten cathode aluminum. This leads to a decrease in the energy yield of the metal, since the electrodynamic forces in the molten metal are unbalanced and a circular movement of the metal and a distortion of the level of its surface occurs in it. The purpose of the invention is to increase the yield of the metal by reducing the effect of the magnetic field on the cathode aluminum. The goal is achieved by the fact that the anodic distribution bus through the drain, located at its ends, and bypass tires is connected with the cathode tire packages of the inlet side of the cathode jacket and through the drain pipes installed at the inlet side of the cathode housing, simultaneously with the cathode tire package of the output the sides, and through the bypass tires, with cathode tire packages of the inlet side of the cathode jacket of the previous electrolyzer series, and through the drainage stations located at the ends of the anodic distribution bus, 1/4 passes through 1/8, and through the ossal stations ki - 1/4 - 3/8 of the current lo p-chi. This current distribution over the racks corresponds to the equilibrium condition of the electrodynamic forces in molten aluminum, taking into account the magnetization field of the ferromagnetic structures of the cathode casing. The drawing shows a diagram of an electrolysis cell busbar with current distribution in sinks and cathode packs. Anodic distribution bus 1 is connected via cathode tires 4 and 5 with cathode bags and 7 and 7 of the input side 8 of the cathode jacket of the previous one (via the current flow J series) of the electrolyzer 9, will form an electrical circuit of the current. Through rungs 10 and 11, the anodic distribution bus 1 is connected with the cathode packs 12 and 13 of the output side 14 of the electrolyzer 9, and part of the packs of bypass tires 15 and 16 with the cathode packs b and 7 of the input side 8 of the electrolyzer 9. Runs 10 and 11 located at the inlet side 17 of the cathode casing of the subsequent one (along the current J of the seriesJ of the electrolyzer 18, the busbar works as follows. After turning on the electrolyzers under load and raising the current of the series to the nominal value J, a current of 1 / J flows through the cathode packs . By parts of the bypass tires 15 and 16, depending From the power and the design of the transverse electrolytic cell, a current of up to 1/8 J branches off. From two ends to the distribution anode bus 1 through stand 2 and 3 passes n G / 4-1 / 8) J, and through stand 10 and 11 1 / 4-3 / 8 current J series. | The magnetic fields created by the currents in the bypass tires 4 and 5 are compensated by the fields created by the currents (1/43/8) J, taking into account the magnetization fields of the cathode housing. of the invention, an aluminum series electrolysis busbar with its transverse placement in the electrolysis housing, comprising cathode bags of input tires and output sides of the cathode jacket, bypass tires, drainage pipes and anodic distribution busbars, in order to increase the metal output by reducing the impact of a magnetic field on the cathode aluminum, an anodic distribution bus through the drain, located at its ends, and bypass tires connected to the cathode tire packages of the inlet side of the cathode shell, and through the drain, mouth Ovens at the inlet side of the cathode casing are simultaneously connected with the cathode packages of the output side tires, and through the bypass tires with the cathode packages of the tires of the input side of the cathode casing of the previous electrolyzer series, and through the sinks located at the ends of the anode distribution bus passes 1/41 / 8, and through the remaining 100 ki - 1 / 4-3 / 8 of the current series.
