摘要
目前,大量二次设备均由单电源供电,失电事件频发。为提高二次设备供电可靠性,研制了一种多功能变电二次设备双电源切换装置,通过继电器互锁原理实现双电源切换,统一母版设计同时满足交直流切换,同时整合电压监测、远方遥控、故障闭锁和主回路闭锁等功能。
At present,a large number of secondary equipment is supplied by a single power supply.Frequently power failure events occurred.In order to improve the reliability of power supply for secondary equipment,a kind of dual-power switching device for secondary equipment is developed,which integrating voltage monitoring,remote control,fault locking and main loop locking and other functions.The switch of double power supply is realized by the principle of interlocking relay,and the unified master plate design meets AC/DC switch.
