Taking into account energy saving and high efficiency and environmental adaptability, promoting the sustainable transformation of heavy energy-consuming industries
In heavy energy-consuming industries such as petrochemicals, metallurgy, mining and non-ferrous metals, energy saving and consumption reduction and environmental adaptability of equipment are the key to industrial upgrading. These industries are also facing the challenge of harsh working conditions, which puts higher requirements on the practicality, electromagnetic compatibility and reliability of low-voltage inverters. Due to different operating scenarios and different equipment, enterprises in various industries have different focuses on the application of low-voltage inverters in production.
Among them, the petrochemical industry generally faces harsh working conditions. Whether it is submersible pumps for oil production, raw material delivery pumps and oil pumps in refineries, or fans and water pumps used for belt conveyors, gasification devices and drying equipment, as well as stirring and material transportation for reactors, low-voltage inverters are required to have excellent practicality, electromagnetic compatibility and high reliability.
In the metallurgical industry, low-voltage inverters are mainly used in high-load equipment such as rolling mills, coilers, fans and processing lines. Enterprises not only have to deal with typical problems such as high temperature, dust, and corrosive gases in the working environment, but also have to maintain the continuous and efficient operation of the equipment for 24 hours. Therefore, they pay more attention to the continuous operation capability and overload rate performance of low-voltage inverters.
In the non-ferrous metal industry, which has similar working conditions to the metallurgical industry, low-voltage inverters are mainly used for core equipment including smelting furnaces, rolling mills, and extruders. They must have high-precision torque control capabilities (±0.5%) and synchronization with multiple motors. They must also have corrosion resistance and rapid response capabilities to cope with the severe challenges of frequent load changes in the rolling process.
In addition, in the mining industry in remote areas, mining equipment such as conveyor belts, hoists, and ventilation systems are mostly operated underground, and must deal with humid and high-dust environments with PM10 concentrations of more than 100mg/m³. At the same time, the high mechanical stress caused by the frequent start and stop of heavy-duty equipment and the unstable factors of grid voltage fluctuations have put forward severe tests on the reliability and stability of low-voltage inverters. Especially in specific scenarios such as coal mines, gas safety issues are a key link that cannot be ignored.
In this regard, Schneider Electric’s ATV series low-voltage inverters can effectively cope with the challenges of complex working conditions in various industries with its excellent environmental adaptability, helping enterprises break through the bottlenecks of accuracy and environment. Both products have 3C3 and 3S3 protection levels, provide IP54 dual duct design and IP55 single-machine protection level, and integrate C2/C3 EMC filters to easily cope with harsh environments and meet electromagnetic compatibility requirements. By adopting redundant configuration and wide voltage input, this series of inverters can effectively adapt to grid fluctuations, further improve reliability, and support four-quadrant operation, achieving a braking energy feedback rate of more than 97%. In addition, with the support of predictive maintenance, this series of inverters also greatly reduces the probability of unexpected equipment downtime.
In the petrochemical industry, Schneider Electric’s ATV600 series low-voltage inverters focus deeply on the core demands of industries such as petrochemicals, coal chemicals, new materials, and fine chemicals. With a unique filter combination, it can easily cope with the challenge of ultra-long motor cables; with rich experience in engineering system design, it provides high-quality solutions for special applications such as submersible pumps. In the non-ferrous metal industry, Schneider Electric’s ATV900 series low-voltage inverters help the industry achieve high-precision torque control and multi-motor synchronization on the core equipment of rotary smelting furnaces and casting machines. In the metallurgical industry, Schneider Electric’s ATV900 series low-voltage inverters make complex applications such as converter tilting and blast furnace loading that require multi-motor coordination control easy with their excellent master-slave functions; programmable options integrate customers’ rich experience into equipment control to maximize efficiency; and integrated cooling design greatly improves the ability to survive in high temperature, dust, and corrosive gas environments. In the mining industry, Schneider Electric’s ATV900 series low-voltage inverters use wide voltage input to effectively adapt to power grid fluctuations, helping the industry save energy and reduce consumption and extend the service life of equipment.
