ATV71系列变频器是施耐德公司的新一代产品,它的行业应用较为广泛。南钢2×220m~2烧结工程各系统在需要调速的设备上都选用了ATV71系列变频器作为调速控制主元件,而烧结冷却系统作为整个2×220m~2项目的主要系统,其使用ATV71系列变频器的情况对维持生产安全稳定具有重要影响。现通过实例分析了ATV71变频器在烧结冷却系统应用的控制电路,针对存在的问题,给出了电控改造措施,取得了明显的效果,对于各类使用ATV71变频器和变频电机作为主要控制运行元件的工矿企业具有良好的借鉴作用。
ATV71 series inverter is Schneider Electric’s new generation of products, its industry is more widely used. The system of 2 × 220m ~ 2 sinter project of Nangang selects the ATV71 series inverter as the main component of speed control on the equipments that need speed regulation. Sintering cooling system is the main system of 2 × 220m ~ 2 project. The situation of ATV71 series inverter has important influence on maintaining production safety and stability. An example is given to analyze the application of ATV71 inverter in the sintering cooling system control circuit, for the existing problems, given the electric control transformation measures and achieved significant results for all types of use of ATV71 inverter and variable frequency motor as the main control operation Components of industrial and mining enterprises have a good reference.
