A cross-slot shunt busbar device for aluminum electrolytic cells

Abstract

The invention discloses a cross-slot diversion busbar device for an aluminum electrolytic cell. The inclined section (1) of the busbar of the downstream tank column is connected with the left crimping joint (2), the left crimping joint (2), the soft section of the left busbar (4), the hard section of the busbar Section (7), right crimping joint (10), and right busbar soft section (9) are connected sequentially by welding, and the hard section (7) of the busbar is fixed with the main mounting frame (8) by bolting, and the main mounting frame (8) The middle section is provided with a right leg (13) and a left leg (14), and the folding leg (17) is hinged to the left leg (14) through a hinge shaft (16); the folding leg (17) is supported on the groove edge plate (19) Above; the right section of the main installation frame (8) is provided with a support beam (12), and the support beam (12) rests on the anode busbar (11); the right section of the main installation frame (8) is connected to the oblique section of the busbar of the downstream slot column (1) ; The main installation frame (8) is also provided with a steel wire rope support (6), and the steel wires at both ends of the wire tensioner are respectively connected with the left crimping joint and the steel wire rope 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...
