摘　　要：设计了一种基于故障电流和弧光双重判据的开关柜短路燃弧故障检测与保护装置。装置采用硬件为主、软件为辅的方式来实现燃弧故障的检测,并且能在故障发生后输出相应的故障信息,有助于对故障点的定位,缩短故障排查时间;同时,在检测到故障发生后,将立即触发快速接地开关动作,快速阻断燃弧的发展,有助于提高开关柜的安全性和可靠性,具有较大的实用价值。A detection and protection device for short-circuit arcing fault in switchgear combined arc light with short circuit current as criterion of arc fault was introduced.Through the method based on hardware and supplemented by software,the device can not only identify the arc fault quickly,but also provide appropriate fault information which can help to locate the fault point,shorten the troubleshooting time.Meanwhile,after a failure is detected,the device will immediately trigger speed grounding switch action,blocking the development of the arc rapidly,improve the safety and reliability of switchgear and have great practical value.
