Description

technical field [0001] The invention relates to a processing system, specifically, a signal phase-locked processing system 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 anode current during the production process of prebaked electrolytic cells. The traditional anode current detection system adopts the manual measurement method of offline equidistant voltage drop. Due to the manual measurement of offline 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 distribution. With the conti...
