RED670 bus protection device is a high-performance, intelligent microcomputer-based relay protection device launched by ABB, designed for the protection and monitoring of busbars in power systems. With its advanced technology and rich functions, the device plays an important role in ensuring the safe and stable operation of power systems.

　　Product Features

　　Highly integrated and intelligent:

RED670 busbar protection device is highly integrated and intelligent, and can realize fast and accurate judgment and fault location of power system.

　　Multiple protection functions:

Differential protection: By detecting the current size and phase relationship of each branch of the busbar, it can determine whether there is an internal or external fault, and quickly cut off the fault path when a fault occurs.

　Zero-sequence current protection: For single-phase grounding faults, it can effectively measure and judge the zero-sequence current component of the busbar and its auxiliary equipment, so as to implement fast protection action.

　Overcurrent protection: By monitoring the current amplitude, short-circuit faults exceeding the rated current on the busbar are prevented.

Voltage protection: Including negative sequence voltage, phase voltage imbalance and other protections, used to detect whether the busbar operation status is normal.

　Reclosing function: Cooperate with the circuit breaker to realize automatic reclosing after a fault, and improve the reliability of power supply.

Remote operation and communication function: RED670 supports data interaction and remote control with other background monitoring systems or dispatching centers through network interfaces to realize intelligent management of power systems.

　　Flexible configuration and scalability:

The RED670 busbar protection device has flexible configuration and scalability and can be customized according to the actual needs of the power system.

Supports a variety of CT input configurations to meet busbar protection needs of different scales and complexities.

　　Powerful communication function:

Supports data interaction and remote control with other background monitoring systems or dispatching centers through network interfaces.

Follow international standards such as IEC 61850 to ensure seamless integration with substation automation systems.

　　High reliability and stability:

The RED670 busbar protection device adopts advanced hardware and software design to ensure stable operation in various harsh environments.

With complete self-test and fault diagnosis functions, it can detect and deal with potential problems in a timely manner.

　　Application scenarios
