摘　　要：分析了自动转换开关(ATSE)动作时间与接触器释放时间,确定ATSE自复动作完成后电机主回路的状态。研究了电机断电重合闸瞬态时,定子电动势、定子电流等参数与额定状态下关系,表明缩短ATSE自复动作时间并不可行,并阐述了消防型ATSE自复功能的使用建议及措施。The action time of automatic transfer switch equipment(ATSE)and release time of contactor were analyzed.The state of motor main circuit was determined after ATSE self-recovery.At the same time,the relationship between the parameters of stator electromotive force,stator current and rated state was studied when the motor was in the transient state of power-off reclosing.It shows that it is not feasible to reduce the action time of ATSE self-recovery.The suggestions and measures for the use of fire fighting ATSE self-recovery function were given.
