摘要
同步电机励磁系统供电电源断电时间在200 ms以内时对同步电机的运行是没有影响的。为了降低供电系统电源波动或受电撤回造成同步电机停机的风险,在供电系统中加装快切装置和UPS能够有效保证供电电源的可靠性。
The power off time of within200ms of the synchronous motor excitation power supply source has no effect on the motor operation.To reduce the risk of synchronous motor shutdown by system power supply fluctuation or power receipt withdrawal,adding fast switch device and UPS in power supply system can effectively ensure the reliability of power supply source.
