Product Advantages and Features ABB REM615 HBMBCAAJABC1BNN11G

1. Multi-function integrated protection, one device for multiple scenarios

   ABB REM615 HBMBCAAJABC1BNN11G integrates over 10 kinds of protection and control functions, covering the core protection needs of medium-voltage electrical equipment such as transformers, motors, and distribution lines. Compared with traditional separate protection devices, it reduces the number of equipment in the cabinet by 60%, simplifies wiring, and lowers the overall system cost and failure points.

2. High-precision measurement and fast protection response

   The device adopts a 16-bit high-precision A/D converter, with current and voltage measurement accuracy up to ±0.2% FS, which can accurately capture the transient changes of electrical parameters. The protection action response time is less than 20ms, which can quickly cut off the fault circuit in case of short circuit or earth fault, minimizing the impact of faults on the power system.

3. IEC 61850 compliant, easy for intelligent grid integration

   ABB REM615 HBMBCAAJABC1BNN11G supports the IEC 61850 communication protocol, which is the international standard for intelligent substations. It can realize seamless data interaction with the upper-level monitoring system, realize remote setting of protection parameters, real-time monitoring of equipment status, and fault record analysis, laying a solid foundation for the intelligent transformation of power systems.

4. Strong environmental adaptability and reliable operation

   ABB REM615 HBMBCAAJABC1BNN11G has passed strict industrial environment tests, with wide temperature range, anti-electromagnetic interference, and anti-vibration performance. It can stably operate in harsh environments such as high-altitude substations, coastal industrial parks, and desert photovoltaic power stations, with a mean time between failures (MTBF) of more than 80,000 hours.

Application Cases ABB REM615 HBMBCAAJABC1BNN11G

1. Industrial factory medium-voltage distribution system protection

   In a large steel plant’s 10kV distribution network project, ABB REM615 HBMBCAAJABC1BNN11G is configured for each distribution line and transformer. It provides overcurrent and earth fault protection, and uploads real-time current and voltage data to the central monitoring room through the IEC 61850 protocol. When a short-circuit fault occurs in the workshop, the device acts within 15ms, isolating the fault point and ensuring the normal power supply of other production lines.

2. Wind power plant grid-connected protection and control

   In a 50MW onshore wind power plant project, the device is used for the grid-connected protection of each wind turbine transformer. It monitors the grid voltage and frequency in real time, realizes the smooth grid connection of wind turbines, and provides overvoltage protection when the grid voltage fluctuates, effectively preventing the damage of wind turbine inverters caused by grid faults. The system’s grid-connected stability is increased by 35%.

3. Commercial building power distribution safety protection

   In a super high-rise commercial building’s power supply system project, ABB REM615 HBMBCAAJABC1BNN11G is installed in the main distribution room to protect the main transformer and power distribution lines. Its precise measurement function realizes the real-time monitoring of the building’s power load, and the overcurrent protection function prevents the overload operation of electrical equipment, ensuring the safe and continuous power supply of the building’s elevators, fire protection systems, and business facilities.

Competitor Comparison

Selection Suggestions

1. For medium-voltage distribution systems of industrial plants, wind/solar power plants, and high-rise buildings, ABB REM615 HBMBCAAJABC1BNN11G is preferred due to its multi-function integration and high protection accuracy.
2. If the project involves intelligent substation transformation or needs to comply with the IEC 61850 protocol, this device is the ideal choice compared with products that only support traditional communication protocols.
3. For projects in harsh environments such as high altitude, coastal areas, and deserts, the device’s wide temperature range and anti-interference performance have obvious advantages over competitors.

Precautions

1. During installation, ensure that the CT and PT secondary side wiring is correct, and avoid reverse connection of the polarity, which may cause protection misoperation or refusal to operate.
2. When setting protection parameters, adjust the current and voltage thresholds according to the actual rated parameters of the electrical equipment, and conduct a simulation test to verify the protection action reliability.
3. Regularly check the communication connection status, back up the protection configuration parameters, and update the device firmware according to the manufacturer’s guidance to optimize the device performance.
4. During maintenance, cut off the operating power supply first, and avoid touching the live parts of the terminal block to prevent electric shock or device damage.
