In the aluminum power plant, the high current output from the rectifier cabinet generates a strong magnetic field, which interferes with the normal work of the measuring equipment. Fiber optic current sensor is based on optical principle, which can effectively shield the surrounding strong electromagnetic field interference and ensure reliable data. Help enterprises to realize accurate current measurement and guide safe production.

As a hub for power collection and distribution, the bus bar carries a huge amount of current, and its current stability is crucial to the entire smelting process. SIO Large DC Fiber Optic Current Sensors are more accurate, not subject to magnetic field interference, and can accurately measure the total series current of electrolysis tanks, which can provide accurate control signals for tank control machines and rectifier cabinets.

By analyzing the trend of cathode current distribution, early breakage of electrolysis cell can be detected and precise location can be realized. Compared with the traditional solution, it can greatly reduce the judgment time and avoid misjudgment.

By analyzing the anode current distribution of the electrolysis cell before and after the pole change, it can be used for lean control and timely discovery of low-voltage anode effect and anode long bag phenomenon.

In the process of aluminum electrolysis production, aluminum electrolysis cell as the core equipment, the stability of its current distribution is directly related to the production energy efficiency, tank life and product quality. However, traditional monitoring methods are limited by high temperature, strong magnetic field, and other complex working conditions, and there are problems such as low precision, difficult maintenance, and data lag. Our aluminum electrolysis cell online measurement system based on fiber-optic current sensor technology breaks through the problem of accurate measurement technology and field application of anode and cathode current distribution in electrolysis cell, subverts the current status quo of relying on the measurement of voltage drop and series current for production process control, provides accurate data support for electrolysis cell process improvement, intelligent control and health monitoring, and helps enterprises realize intelligent upgrading.
