Product overview Technical advantages Functional characteristics

Generally new start-up or normal production electrolysis cell, cathode and anode, the voltage drop is within a certain range, when the assembly quality of unqualified cathode and anode carbon block on the cell into production, the bottom of the furnace voltage drop and anode voltage drop rise, and energy consumption rises. Therefore, on the premise of ensuring the quality of assembly materials, it is necessary to strengthen the monitoring of assembly quality. The premise of strengthening the monitoring of assembling process is that the voltage drop of assembled cathode or anode carbon block can be timely and accurately detected, and the unqualified carbon block can be timely dealt with to avoid it being put into the furnace.

The measurement principle of JW-180 Iron Carbon Voltage Drop Tester developed by Jingwei Technology is to use full-bridge high-frequency constant-current power supply as the core current output, which is designed for the external load change, keeping the output current constant through internal adjustment , to avoid the current change or attenuation due to load change.

The industry has used DC welding machine to check the quality of cathode assembly, the disadvantage is that the test principle of the welding machine is a regulated voltage output, the output can ensure that the load (output current) changes, keep the voltage constant, and the current output also changes, that is, the output current is not a constant value. DC welding is mainly used in the welding industry, where a constant current is not required and the attenuation of the current changes indeterminately with the external load, so there is no basis for comparison or calculation.

• Multifunctional switch: test current 200A/400A, test time can be switched.
• Accurate measurement: Adopting the latest power supply technology, it can continuously output large current for a long time.
• It overcomes the technical problems of unstable current and inaccurate measurement results of similar products.
• Strong anti-interference ability: under severe interference conditions, the display reading is stable.
• Printing function: no need for on-site data recording, test data can be printed.
• Easy to carry and move: small size and light weight.
