The method of regulating the single anode pole distance in aluminum electrobath based on energy saving includes the following steps: lowering the anode crossbeam bus until reaching tank voltage fluctuation over 80 mV, measuring anode current, measuring single anode pole distance in aluminum electrobath, and regulating the key poles according to the anode current fluctuation and pole distance. Thepresent invention regulates according to relation between anode current and the pole distance distribution, and can reduce local horizontal current, reduce average pole distance, decrease aluminum liquid fluctuation, optimize the overall cell condition, raise current efficiency, lower power consumption and increase the life of aluminum electrobath.
