继电保护直流分电屏直流接地报警装置

Relay protection DC divider DC alarm device

针对电力系统中如何能即快速又准确地查找出在直流分电屏的故障,并可以及时将信号发送于主站后台,提出了在继电直流分电屏接地报警装置中查找故障查找的方法。继电保护直流分电屏直流接地报警装置,可以实现在线监测直流分电屏运行状态的目的,准确判断直流回路情况,并将信号及时的传送至调度总站。

In order to find out the fault of DC divider quickly and accurately in power system and send the signal to the main station in time,the method of finding fault in grounding alarm device of relay DC divider is proposed.The DC grounding alarm device can monitor the DC operation status on line,accurately judge the DC circuit and transmit the signal to the dispatching station in time.
