| 摘 要： | 针对400 V备自投开关切换至短路母线上时往往由于备自投装置的选择性问题导致进线开关跳闸进而使得低压系统全部失电,提出了保护整定配合和区域选择性联锁的解决方案,有效避免了因低压备自投误动导致的扩大性跳闸。

| Abstract: | Aiming at that the selective protection of reserve automatic closure（RAC） in a 400 V system led to input line circuit breakers tripping to cause the power failure of the whole low voltage system when the RAC was switched to short-circuit bus,the solution of protection adjusting and zone selective interlocking（ZSI） was proposed to avoid override trip effectively by the RAC error. |
