TMEIC高压变频器在高炉鼓风机同步电动机软启动中的应用

Application of TMEIC High Voltage Inverter in Soft Start of Synchronous Motor of Blast Furnace Blower

介绍TMEIC电压源型高压变频器在河北纵横集团丰南钢铁有限公司炼铁工程新建4座高炉配套鼓风机10kV交流无刷励磁同步电动机软启动应用及效果;软启动系统采用二拖六配置方式,TMEIC变频器软启动为静止软启动方式,通过内部同期及外部同期双同期方式安全准确完成高炉电动机软启动同步投切,软启动投切过程为无扰切换。

The application and effect of TMEIC voltage source high voltage converter in soft start of 10 kV AC brushless excitation synchronous motor of 4 new blast furnaces in iron-making project of Fengnan Iron and Steel Co., Ltd. of Hebei Longitudinal and Horizontal Group. The soft start system adopts two-tow-six configuration mode,and the soft start of TMEIC converter is static soft-start mode, which is safe and accurate through both internal and external dual synchronization modes, and the switching process of soft start is disturbance-free switching.
