Description

technical field [0001] The invention relates to an on-line measurement device based on the anode current distribution of an aluminum electrolytic cell, in particular to an on-line measurement device and a measurement method based on the anode current distribution of an aluminum electrolytic cell. Background technique [0002] At present, in the existing aluminum electrolysis industry, in the production process of prebaked electrolytic cells, it is necessary to measure the distribution of anode current every day, which is measured by manual measurement means of off-line equidistant voltage drop. [0003] However, since this measurement method cannot eliminate the influence of the temperature change of the anode guide rod on the anode current measurement, there is a large measurement error; in addition, because manual measurement can only measure one anode at a time, after the operation The measurement of the next anode is carried out again and again, not only the measurement ...
