Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the utility model is further described:

[0028] It can be seen from Figure 1 that the electrolytic cell body 1 is the cathode, the anode bus 2 forms a current path through the anode carbon block and the cathode under it, the short-circuit block 3 is connected to the outlet bus 5 through the short-circuit bus connected to it, and the power-in terminal bus 4 is the column busbar; when the electrolyzer is in production, the current enters 2 from the power-incoming busbar 4, and is introduced into the cathode through the anode carbon block connected with the anode busbar 2, and is output from the cathode busbar 5, and enters the next electrolyzer to form a series series Circuit; when the electrolyzer is stopped, all short-circuit blocks 3 need to be connected with all columns 4, usually in the form of crimping, and the short-circuit blocks 3 are crimped to the columns through bolts, and there are 1 to 2 short-circuits on each ...

Abstract

The invention discloses a current conversing method and device of aluminium electrolyser, which is characterized by the following: adopting transition conversing pattern to open or close groove; crimping short-circuit block on the column and column when the electrolyser lies at groove-closing time; making most of current enter into short-circuit mother wire circuit through power inlet end; entering current from short-circuit block into next electrolyser; realizing groove-closing; paralleling fuser on two ends of short-circuit hole when the electrolyser lies at groove-opening time; starting short-circuit block; connecting strong current on the fuser; breaking short-circuit block; fusing the fuser; making current of short-circuit into electrolyser; eliminating electric arc in the closed circuit.

Description

Technical field: [0001] The invention relates to a method, in particular to a method and a device for stopping or starting the electrolytic cells under the full current state of a series of aluminum electrolytic cells. Background technique: [0002] In the production process of electrolytic aluminum, after the electrolytic cell reaches a certain service life, it must be stopped for overhaul. The current on the electrolytic cell directly enters the next electrolytic cell through the short-circuit busbar to realize the shutdown of the electrolytic cell. After the overhaul, the electrolyzer should transfer the current flowing through the short-circuit bus to the electrolyzer, that is, open the short-circuit block in the closed state. Due to the high series voltage and large current, the current current conversion method is to open or close the short-circuit block in the busbar of the aluminum electrolytic cell after a series of power outages or a large reduction in current, so...
