摘　　要：针对当前国内中低压母线没有快速保护的现状,设计了目前国内第一套弧光保护系统DPR360ARC,该系统采用基于紫外传感器的弧光探头技术和基于FPGA的高速串行通信技术,实现了母线、开关柜的快速保护,从弧光发生到跳闸出口的时间控制在4ms以内。DPR360ARC的应用有利于提高中低压输电线路的安全可靠性,为开关柜、母线和各种变流设备的弧光故障提供全面的保护,将对设备的损害和人员安全的威胁降至最低并确保电网平稳安全地恢复。Noticed the fact that there is no fast protection for medium and low voltage currently,the first domestic set of arc protection relay system DPR360ARC is designed.This system applies the techniques of arc probe technology based on UV sensors and high-speed serial communication technology based on FPGA,and realizes the rapid protection for bus and switchgear.The time from arc occurs to the export trips can be limited to 4 ms,which greatly improves the reliability of medium and low voltage transmission line.Also,this system can provide overall protection corresponding to the arc faults of bus,switchgear,kinds of rectifier equipment,greatly reduce the risk of equipment＇s damage and worker＇s death,and ensure the grid＇s safe and smooth recovery.
