1MRK002311-AAR02

High voltage line longitudinal differential protection data exchange
Line differential protection: realizes real-time synchronous sampling and data exchange (instantaneous values of current and voltage) between the two ends of the substation line protection device. It is an essential board for fiber optic longitudinal differential protection and cannot be put into operation without it;
High frequency interlocking/remote tripping: transmitting remote tripping and fault interlocking logic signals, and transmitting tripping commands across stations in milliseconds at the moment of fault;
Protocol: Native adaptation to ABB protection private differential protocol+IEC60870-103 relay protection communication standard.
Super strong electrical isolation, resistant to strong electromagnetic interference from substations
Fiber optic physical isolation of strong and weak electricity, isolating EMI electromagnetic interference caused by bus short circuits, lightning, and switch opening and closing, and preventing protection misoperation/refusal caused by ground potential interference;
The only reliable long-distance channel solution for strong electromagnetic field environment in high-voltage substations.
Link online diagnosis and fault alarm
Real time monitoring of received optical power, optical link loss, and fiber breakage;
The automatic feeding device for fiber breakage/excessive light attenuation alarms and locks differential protection to prevent false tripping caused by abnormal data;
Report dual fault points on the panel and device backend.
