    2. The busbar according to claim 1, about 1 ton and that the combined cathode bus bars contain stands arranged symmetrically with respect to the transverse axis of the electrolyzer.
    3.Oshinovka on PP. 1 and 2, as with
    The two-bottom arrangement of electrolyzers in the case of the electrolysis of rsin i STO5PS is located at the end of the cathode shell, bluish to the adjacent row of electrolyzers Ja the rest, along the side of the cathode and on the case next in the row of the electrolyzer.
    The invention relates to the production of aluminum, in particular, to a device for supplying current to electrolyzers located transversely in two rows. The current from the cathode rods of the electrolyzer is fed through flexible current leads to cathode tires partially assembled in packages, and along the lines (packages busbars installed, vertical but) the current goes to the anode busbar of the next in this row of the electrolyzer. The transfer of current through the cathode busbars of one electrolyzer and to the cathodes to the anodic tires of the next is accompanied by a power loss of approximately 1 kWh / kg of molten metal. The currents in the busbar also create a magnetic field, which, together with the horizontal currents in the molten aluminum, excites electromagnetic forces in it that interfere with the normal electrolysis process. With a good choice of the busbar circuit, the ohmic losses in it and the harmful effects of electromagnetic forces can be reduced. The known busbars of electrolyzers for the production of aluminum, part of the cathode tubes of which are located under the bottom of the cathode shell. Tires, combined into packages, are connected by means of runways to the anode busbar of the cell near the electrolyzer. All rungs are placed evenly along one side of the cathode cell of the electrolyzer, symmetrically with its transverse axis lj. A device is known for a bus-bar in which a part constituting less than half of the current of the electrolyzer is directed to the cathode tires located under the cathode casing, and the rest of the current through the tires assembled in packages, bypasses the cathode casing from the ends. The tires passing under the cathode achozhuha are bagged and placed near the transverse axis of the cathode casing so that the current is supplied to the anode busbar of the next electrolyzer through four hundred cells located symmetrically with respect to the transverse axis of the electrolyzer 2. It is also known the technical solution in which the cathode tires from the input side of the current into the electrolyzer are assembled into two packages, passing under the cathode casing, by means of two sinks connected to the anode busbar of the next electrolyzer in the row, while Packed cathode tires round the ends of the cathode casing of this electrolyzer and approach the stoves located at the end of the cathode casing of the subsequent electrolyzer h. A common drawback of the known technical solutions is the adverse effect of the magnetic field and ohmic energy loss in the busbar. The purpose of the invention is to increase the productivity and reduce the harmful influence of the magnetic field on the electrolysis process from the melt. The goal is achieved by the fact that in the busbar of aluminum electrolyzers, installed transversely in the electrolyzer housing containing cathode rods in pairs extending beyond both sides of the cathode casing, and cathode tines connected with them, partially packaged, which are connected with the anode busbar of the next a series of electrolyzer sinks placed at its side and ends, with cathode busbars, the rods are grouped into groups composed of conventional cathode rods and rods shunted by individual, tires passing under the bottom to The number of cases in one group does not exceed five, and the total number is half of all cathode rods, and the busbars of the groups made up of non-shunted rods are combined into packages located on both sides, bypassing the cathode case of the electrolyzer from the ends, and the groups made up of shunt and unshunted cathode rods are arranged in alternating sequence and their cathode assemblies are combined into packages. In addition, in the busbar, cathode busbars contain stacks placed symmetrically relative to the transverse axis of the electrolyzer. With a two-row bottom arrangement of electrolyzers in the housing, one is located at the end of the cathode battery closest to the adjacent row of electrolyzers, and the rest along the bead of the cathode housing that is next to the row of the electrolyzer. FIG. 1 shows a busbar for a pepper electrolyzer, a plan; FIG. 2 - the same, side view; FIG. 3 busbar with tire asymmetry relative to the transverse axis of the electrolyzer and the stand located at one end of the cathode shell; FIG. 4 is the same, with the asymmetry of the supply of current to the end station; FIG. 5 is a variant of the design of busbars. . The electrolyzer 1, located transversely in the electrolysis housing (Fig. 1), contains fifteen cathode rods 2 protruding on both sides of the cathode casing 3. The ends 4 protrude on the input side of the current X, the ends 5 on the output side of the current (output side) electrolysis cell of three middle rods, bridged by tires 6, passing under the bottom of cathode casing 3. Three central cathode rods and output ends 5 of two adjacent rods are combined into a collective package 7 ,. which further forms an inclined one-to-eight, which connects the cathode busbar electrolyzer 1 with the anode busbar 9 of the next-to-follow electrolyzer in the series 10. Other pairs of shunting and non-shunting cathode rods are combined with the ends of 5 non-shunt cathode rods 4 on the side of the inboard side, the packages 12 and 13 run along both ends of the cathode skin; ha and in the form of packages of cathode tires 14 and stands 15 and 16, located at the ends of the cathode housing 3, rise to the anode busbar 9 next in the row of the electrolyzer. 10. Connection of the cathode rod. 2 with a shunt busbar B carried out by elastic inserts 17 and 18, in a TaKiiM manner, the cathode part of the bus-bar (Fig. 1 2) is formed by groups of cathode tires joining the two branches of the two cathode rods, and these groups are located symmetrically with the transverse axis of the cathode the cell housing. Groups composed of unshunted and shunted cathode rods are arranged in an alternating sequence, and the number of shunted cathode rods does not exceed half of their total number. An asymmetric busbar (FIG. 3) in a transverse electrolyzer 1, having twenty-five cathode rods 2, of which every second is bridged by bus 6, passing under the bottom of the cathode casing 3, formed by four groups containing three cathode rods formed by combining the ends 4 and 5 cathode rods on each side of the cathode jacket by busbars. At the same time, busbars 19-21 run along one end of the cathode casing to an aisle 15 connected to the anode busbar of the 9th electrolyte; 10, and tires 22 along the opposite end of the electrolysis cell 3, combining the ends 5 of three shunting and three non-shucked cathode rods 23, and then by means of a stand 24 of the cathode busbar of the electrolyzer is connected with the anodioG busbar 9. On the output side of the cathode case two next groups are formed by combining into tires 25 and 26, which have their own sticks 27 and 28. The latter group of two rods by means of clay 29 is poured into a stack of tires 15. The cell axis of the electrolysis cell is located at the end of the electrolyzer facing the adjacent row, while one hundred and fifteen. The arising asymmetry of the magnetic field in the melt of electrolyzers of this row compensates for the magnetic field created by the currents of the electrolyzers of the adjacent Asymmetry of the magnetic field when the current to the next electrolyzer 10 in the row is placed along one side of the cathode casing, created by the following switching circuit (Fig 4): all twenty-five cathode rods are combined into five groups of five rods, two of which are made up of 6 rods shunted by tires and arranged in an alternating sequence . The groups are combined with busbars t9 and 20, which bypass electrolytes9 22 - from one end of the tire, and another tire. The ends of the rods 5, also by five pieces, are combined into packages with their own stands, respectively. Cost 27 combines the ends 5 of two groups connected by stand 28 with the anode busbar 9 of the cell 10. It is this group that provides asymmetry of the field relative to the transverse axis of symmetry of each cell of a given row to compensate for the adverse effect on the process of electrolysis of the field of the adjacent row of electrolyzers. In the proposed busbar of the electrolysis cell (Fig. 5), the ends 4 of the cathode rods are combined with tires 20-22, and the ends 5 are connected with tires 25 and 26, which then supply current to the next electrolyzer with three racks 24, 27 and 28. Elastic inserts 17 and 18 connect the ends 4 and 5 of the cathode rods with shunt tires 6. This design is an example of an asymmetric busbar of an aluminum electrolyzer with transverse placement in the electrolysis housing.
