Generally, for newly started or normal production electrolytic cells, the voltage drop of cathode and anode is within a certain range. When the cathode and anode carbon blocks with unqualified assembly quality are put into production, the voltage drop of furnace bottom and anode increases, and energy consumption increases. Therefore, it is very necessary to strengthen the monitoring of assembly quality on the premise of ensuring the quality of assembly materials. The premise of strengthening the monitoring of assembly process is to be able to timely and accurately detect the voltage drop of cathode or anode carbon blocks after assembly, and to deal with unqualified carbon blocks in time if they are found to be unqualified, so as to avoid unqualified carbon blocks from being put into the cell.
The measurement principle of the JW-180 Iron Carbon Voltage Drop Detector is to use a full-bridge high-frequency constant-current power supply as the core current output, which is designed for the external load change, keeping output current constant through internal adjustment, to avoid the current change or attenuation due to load change.
