Spectrum Analysis of Anode Rod Current in Aluminum Reduction Cell Based on Wavelet Transform
The signal acquisition system was designed,and the voltage drop of the anode rod of three anodes in the same cell was measured.After the data is processed,the current signal of anode in aluminum electrolysis process is analyzed by wavelet transform.The main frequency range of the anode current in different position is found by the spectrum analysis of the third layer detail signals and the approximation signals.The results show that the spectrum of the three anodes current is roughly similar,but the position of the main frequency changed.The paper discussed the relation of these spectrums with the physical and chemical behaviors of the electrolysis cell.
