摘要
针对船舶空压机电动机过流保护存在的问题,提出了电流不对称保护与相敏保护相结合的数字式过流保护方法,采用双单片机控制GTO进行保护,增加了保护的可靠性。
In light of the problems existing in the over-current protection for the motor of ship＇ s air compressor, a digital over-current protection method combined with current dissymmetry protecting and phase sensitive protecting is introduced. Double single-chip is used to control GTO to realize protection in order to raise the reliability of protection.
