Design of arc protection relay system DPR360ARC

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.
