地铁屏蔽门系统后备电源[不间断电源(UPS)及其备用蓄电池]在应急状态下使用频率极低,所以有人提出取消后备电源以减少投资。本文通过有无后备电源设计方案的比较,对取消后备电源可能存在的问题进行了分析探讨,提出了不应取消的观点,供同行参考。
Subway screen door system backup power [uninterruptible power supply (UPS) and its backup battery] in the emergency state to use very low frequency, it was proposed to cancel the backup power supply to reduce investment. In this paper, by comparing the design of backup power with or without reserve, the possible problems of eliminating backup power are analyzed and discussed, and the view that should not be canceled is put forward for the reference of peers.
