摘要
通过对大容量电动机直接启动的必要条件的分析,并通过对电动机供电系统电压降的核算,对电动机启动功率的分析、核算,阐明了在工程设计中应注意的几个问题:①大容量电动机在启动时对电网的要求;②大容量电动机启动方式的选择;③电动机启动功率的核算;④电动机启动时间的核算等。
The necessary condition of the large capacity motor starts directly was analyzed, and the voltage drop in the motor power supply system was calculated, the paper clarified a few notes in the engineer design:① The requirement of the electrical power network when the large capacity motor starts; ② The mode selection of the large capacity motor starting;③ The calculation of the motor starting power;④ The calculation of the motor starting time; etc.
