Across-cell shunt bus device for aluminum electrolysis cell

Abstract

The invention discloses an across-cell shunt bus device for an aluminum electrolysis cell. An inclined segment (1) of a downstream cell stand-column bus is connected with a left pressing joint (2), and the left pressing joint (2), a left soft bus segment (4), a hard bus segment (7), a right pressing joint (10) and a right soft bus segment (9) are sequentially connected in a welding mode. The hard bus segment (7) is fixed with a main mounting rack (8) in a bolting mode, and the middle segment of the main mounting rack (8) is provided with a right leg (13) and a left leg (14). A folding support foot (17) is hinged with the left leg (14) through a hinged shaft (16) and is supported on a cell margin plate (19). The right segment of the main mounting rack (8) is provided with a strut beam (12), and the strut beam (12) is arranged on a positive bar (11). The right segment of the main mounting rack (8) is connected with the inclined segment (1) of the downstream cell stand-column bus, and a steel wire support (6) is also arranged on the main mounting rack (8). Steel wires of two ends of a tightener are respectively connected with the left pressing joint and the steel wire support.

Description

technical field [0001] The invention relates to a cross-trough shunt busbar device for an aluminum electrolytic cell, which can enable the aluminum electrolytic cell to carry out welding and maintenance work under the full current working condition of the production series. Background technique [0002] At present, electrolytic cell types above 300 kA used in the electrolytic aluminum industry at home and abroad cannot realize welding maintenance operations under the full current condition of the production series due to the excessive magnetic field strength of the welding part. Power failure or reduction of series current seriously affects normal production, resulting in Huge economic loss. Since the magnetic field strength of the welding part is determined by the size and distance of the surrounding current beam, these two parameters can be changed to effectively reduce the magnetic field strength of the target point, so as to achieve the purpose of welding. But all do no...
