Product Description

Distribution Network Automation Terminal DeviceOverview
NRU-200 distribution network automation terminal device uses computer technology, automatic control technology, electronic technology, communication technology and new high-performance distribution equipment and other technical means. It uses high-performance 32-bit microprocessor as hardware development platform and embedded real-time operation with high stability as software development platform to develop a new distribution automation terminal. It integrates the functions of telemetry, remote communication, remote control, protection and communication. It is widely used in multi-loop centralized monitoring applications such as distribution room, ring network cabinet, open and close office, and column switch. It can be combined with the communication system to form the distribution automation system of various loop network and non-loop network with channel mode. It can cooperate with the distribution station and the main station to realize the monitoring of the running state of the distribution line, fault identification, fault isolation and non-fault area restoration of power supply and other distribution network automation functions

Applicable scope
It is suitable for distribution automation construction and transformation of ring network cabinet, distribution room, opening and closing station and box-type substation. The terminal has three mounting methods: cabinet type, wall mounted and embedded.  

.Main function
line monitoring
1.AC and DC sampling: it can collect three-phase AC voltage, current and direct flow, and realize the measurement of voltage, current, active power, reactive power, power factor, frequency, and DC voltage.
2. Remote message: collect and transmit status information to the distance, and the status change is transmitted first;
3. Remote control: receive and execute remote control commands from afar and on the spot;

 
  Fault monitoring and identification and processing capabilities
1.Remote fault detection function: zero sequence detection, over-current detection, line overload detection, line three-phase over-current detection;
2.Telemetry over limit detection function: current over limit detection, voltage over limit detection, zero sequence voltage over limit detection.

 Troubleshooting:
1.Over-current tripping function (three-stage protection);
2.Reclosing function (reclosing times can be set);
3.Dual power supply backup function;
4.FA fault handling function;
5.DA fault handling function: can quickly realize the fault identification, fault upload (location), fault isolation and recovery of non-fault areas between multiple power points;
6.Support conventional DTU/FTU, can be flexibly configured to adapt to current type DA and voltage type DA;
7. Support network protection (face protection, peer-to-peer communication), quickly find and isolate faults without a master station;
8. Support watchdog controller function, quickly remove the user branch line fault;
9.The equipment with the coincidence function is installed at the substation exit of the first switch instead of the exit switch, to avoid frequent exit switch tripping substation.
