针对轧机10KV变压器二次线圈维修后对SL150变频系统的优化及调试,探讨了SL150变频系统中变压器维修后对系统的影响,提出并实施了系统调试方案,消除BD变压器对SL150调速系统的影响,经优化后系统运用平稳。 Aiming at the optimization and debugging of the SL150 frequency conversion system after the secondary coil of 10KV transformer is repaired, the influence on the system of the SL150 frequency conversion system after the transformer is repaired is discussed. The system debugging scheme is put forward and implemented to eliminate the influence of BD transformer on the SL150 speed regulating system , The system is optimized and stable.
