摘要
介绍了广电机房配电系统的电气主接线方式,阐述了不间断电源(UPS)安全操作方法和运行状态。所有UPS输入电源都接在同一段母线上,其中2台30 kVA UPS并机运行,实现互为备份,同时旁路电源都设在专设的旁路开关处,在确保核心机房配电的安全性和可靠性方面起到了重要作用。
This paper introduced the main electrical connection modes of the power distribution system in broadcasting and TV equipment room. The safe operation method and operating state of uninten＇upted power supply （UPS） were elaborated. The inputs of lIPS sources joint the same bus. Two 30 kVA UPSs are operating in parallel which achieves the mutual backup. The hypass power supplies set in the special bypass switch. It plays an important role to ensure the safety and reliability of power distribution system in the core computer room.
