一种交流进线备自投的设计及实现

摘要

To enhance power supply reliability of an important 10 kV distribution room, this paper checks its double circuit 10kV source lines, combines the original cabinet line-loop control, and uses the AC relays. It takes 10 kV bus three-phase voltage loss as its device start element, and designs a AC incoming line for spare power automatic swiching device to ensure safe and reliable power supply of the 10 kV power distribution room.%为提高某重要10 kV配电室供电可靠性,针对其双回10 kV电源进线,结合进线柜内原有控制回路,利用交流继电器,以10 kV母线三相失压为备自投启动元件,设计一种交流进线备自投装置,以确保10 kV配电室安全可靠地供电.
