Description

technical field [0001] The invention relates to a power supply, specifically, an integrated voltage-stabilizing power supply for an anode current measuring device of an electrolytic cell. Background technique [0002] In the domestic aluminum electrolysis industry, it is usually necessary to measure the distribution of the anode current during the production process of the prebaked electrolytic cell. The traditional anode current measurement device adopts the manual measurement method of the off-line equidistant voltage drop. Due to the manual measurement of the off-line equidistant voltage drop The method can only measure one anode at a time, and then measure the next anode after the operation is completed. The measurement procedure of this measurement method is complicated, the workload is heavy, and the measurement time is long, resulting in a time difference in the measurement results, which cannot truly reflect the anode current of the electrolytic cell. of the distribu...
