Industry dynamics and technological breakthroughs:

Upgrade of intelligent power distribution system

REJ601 BD446NN1XG relay realizes the full life cycle management of the power distribution network by integrating overcurrent, ground fault, phase discontinuity and other protection functions. After an industrial park deployed it in a medium-voltage switchgear, the fault response time was shortened from 2 seconds of traditional relays to 0.7 seconds, and the number of annual failures and power outages was reduced by 45%.

Sensor technology innovation

Support Rogowski current sensor interface. Compared with the traditional CT scheme, this modular design improves the installation efficiency by 50%, and the sensor can be replaced without removing the terminal, significantly reducing operation and maintenance costs. After the application of a steel plant, the equipment maintenance cycle was adjusted from the quarterly level to the monthly level.

Strengthen the ability of digital operation and maintenance

Through the docking with the SCADA system through the Modbus RTU and IEC 60870-5-103 protocol, the relay can upload fault records (such as events and interference data) in real time, combined with the local backup function of the USB port to realize data traceability and remote diagnosis. Based on this, a power enterprise optimized the overhead line inspection strategy, and the fault location time was shortened by 60%.

Verification of extreme environmental adaptability

The relay supports wide temperature operation from -40°C to +70°C, with a protection level of IP65. suitable for humid, dusty and other complex environments. After being deployed in a corrosive gas environment, a coastal chemical park operated continuously for 18 months without hardware failure, with a stability of 99.97%.

Technical highlights:

Compact design: the pressure matching installation method reduces the complexity of wiring, and the volume is 30% smaller than that of traditional relays, which is suitable for the layout of compact distribution cabinets.

Self-diagnostic function: built-in sensor abnormal detection, power status monitoring and other 12 self-test mechanisms, supporting remote reset and parameter tuning.

Flexible expansion: Support 1A/5A CT switching, Boolean logic programming and timer configuration, and adapt to the needs of power distribution systems of different scales.

Industry impact:

The launch of REJ601 BD446NN1XG promotes the transformation of the power distribution system from “passive protection” to “active early warning”. Its application in industrial electricity, public utilities and other fields has verified the core value of intelligent relays in improving the reliability of the power grid and reducing operation and maintenance costs, and provided key equipment support for the implementation of Power IoT.
