快速切换装置在异步发电机上的应用

Application of Fast Switching Device in Asynchronous Generator

针对备自投装置需等待失电母线残压完全消失才能投入备用电源的缺陷,采用了快速切换装置来保证系统不间断供电。介绍了快速切换装置的参数和动作时间的计算。

Aiming at the defect that the backup automatic switching equipment needs to wait for the residual voltage of the power-loss bus to completely disappear before switching to the standby power supply,a fast switching device is adopted to ensure the uninterrupted power supply of the system.The calculation of the parameters and operating time of the fast switching device is introduced.
