Abstract

The invention discloses a current distributor which is applicable to an aluminum electrolysis short circuit loop. The current distributor comprises a machine body part, a motor driving part, a contact group part, a distributed cam device and a position incremental encoder. The current distributor has the advantages that the service life is long, the current carrying capability is strong, the speed of the current rising and falling of a short circuit loop is high, the variable range is wide, the operation is easy, the structure is compact, the mounting and maintenance are convenient and the like.

Description

technical field [0001] The invention belongs to the electric industry of DC switches, and in particular relates to a current distributor mainly used in the short-circuit circuit operation during the overhaul of aluminum electrolyzers. Background technique [0002] At present, my country's electrolytic aluminum industry needs to overhaul the aluminum electrolytic cell regularly or irregularly. [0003] Before the overhaul, the production current in the electrolyzer needs to be transferred to the short-circuit circuit. The short-circuit circuit is located under the electrolyzer. When the short-circuit circuit is working, dozens of KA currents pass through it. Each electrolytic cell has a short circuit that creates a complex magnetic field of high magnetic induction around the aluminum electrolytic cell. [0004] During the overhaul, there will be a lot of electrolytic cell welding work, and the welding arc is a conductive body that is sensitive to the influence of the magneti...
