REC670 Interval control equipment
REC670 is an interval control device produced by ABB, commonly used in power systems, mainly used to monitor and control the interval between power equipment.
REC670 has applications in a number of areas, including:
Substation automation: REC670 can be used in substation automation systems to monitor and control the spacing between different devices (such as circuit breakers, isolation switches, etc.) to ensure the safe and reliable operation of the power system.
Power transmission lines: The REC670 can be used on power transmission lines to monitor and manage various equipment on the line for automatic control and protection when needed.
Distribution systems: In power distribution systems, REC670 can be used to monitor and control the spacing between different devices to ensure the reliability and efficiency of the distribution system.
Power equipment protection: REC670 can be used as part of the power equipment protection system to ensure that the spacing between various equipment (such as transformers, circuit breakers) is effectively monitored and controlled to prevent equipment damage.
Remote Monitoring and control: The REC670 may support remote monitoring and control capabilities, allowing remote operators to monitor and control the spacing between different devices, increasing operational flexibility.
In addition, the REC670 also uses dual optical ports to realize the redundancy function of dual-fiber ring network. When an optical fiber fails, the system will rebuild the network link within 10ms to ensure the normal communication of the system and realize the self-healing protection function of signal transmission.
The applications of REC670 are mainly in power systems and related fields, especially in substation automation, power monitoring and protection systems. The following are the main application areas of REC670:
Substation automation: REC670 acts as an interval control unit to monitor and control various equipment in the substation, such as circuit breakers, isolation switches, transformers, etc. Through REC670, the remote monitoring, control and protection of these devices can be realized, and the automation level and operation efficiency of the substation can be improved.
Power monitoring and protection: REC670 is equipped with a wealth of protection functions, such as overcurrent protection, overvoltage protection, undervoltage protection, etc., can monitor the operating status of power equipment in real time, and quickly cut off the fault current in the event of failure, to protect the safety of equipment and power system.
Intelligent distribution network: In the intelligent distribution network, REC670 can be used as the distributed power access point or the control unit of the key node, to achieve the distributed power access management, load management, fault location and other functions, improve the intelligent level and operation efficiency of the distribution network.
Power communication: REC670 usually has an Ethernet interface and serial communication function, which can easily exchange data and communicate with the upper-layer system or other devices. The REC670 can be used as a key node in the power communication system to realize real-time transmission and sharing of power data.
Energy management: REC670 can be used in energy management systems to monitor the energy consumption of power equipment in real time, and through data analysis and optimization of control strategies to achieve efficient use of energy and energy saving and emission reduction.
In summary, the REC670 is a powerful power system control unit for a wide range of applications in substation automation, power monitoring and protection, smart distribution networks, and energy management.
