4200kW同步电动机主回路系统设计

Design of Main Circuit System of 4 200kW Synchronous Motor

以4 200kW交-交变频同步电动机控制主回路工程为例,介绍了主回路线路图,并根据同步电动机的技术参数进行了主回路的参数计算,给出了主整流变压器、晶闸管、励磁变压器以及励磁晶闸管的参数选择方法,为国内其他钢铁企业大型主传动电机改造提供了参考。

Taking the main circuit controlled by 4200kW AC - AC variable frequency synchronous motor for an example, the diagram of main circuit was described in this paper. The parameters of the main circuit were calculated and the main rectifier transformer, thyristor, excitation transformer and thyristor excitation g parameter selection meth- od were given according to the technical parameters of main circuit of the synchronous motor which provided a refer- ence for large - scale transformation of the main drive motor in other domestic steel enteriprises.
