Abstract
The present invention discloses a configuration method of serial aluminum electrolytic tank buses, which compensates the adverse influence of magnetic fields mutually generated by electrolytic tanks in adjacent lines. A secondary power supply (9) is arranged, a bus (2) is led out from a positive pole of the secondary power supply (9), the bus (2) is not coupled in the electrolytic tanks, and the bus (2) orderly goes around the sides of the two lines of the electrolytic tanks and generates a magnetic field for compensation. For the electrolytic series with small distance between electrolytic tank lines, the method of carrying out the non-symmetrical configuration of cathode buses on each electrolytic tank for compensating the adverse influence of the magnetic fields mutually generated by the electrolytic tanks in adjacent lines is no longer adopted after the configuration method of serial aluminum electrolytic tank buses is adopted. Therefore, the use level of the cathode buses is saved, and mounting and constructing processes become simple.
