>>>>型號:RED670 線路差動保護 電力系統(tǒng)保護
【功能描述】
RED670是一種線路差動保護設備，它是Relion系列產(chǎn)品中的一員，旨在滿足電力系統(tǒng)保護的高要求。
RED670的主要特點和功能包括：
適用于各種電壓等級的電力系統(tǒng)，可以用于保護、控制和監(jiān)視架空線路和電纜，包括重負荷線路和多端線路。
支持單相、兩相和三相的跳閘方式，并提供分相差動保護，具有優(yōu)秀的靈敏度和相選擇功能。
可適應不同的網(wǎng)絡結構，包括經(jīng)阻抗接地或直接接地系統(tǒng)，還可以用于保護包括串聯(lián)補償系統(tǒng)在內的各種網(wǎng)絡。
具備后備距離保護功能，當通訊信道中斷時，可以作為選擇性后備保護。
配備電流保護功能，可以有效地檢測線路中的故障電流，同時也擁有電壓保護功能，可以監(jiān)測線路上的電壓變化。
此外，RED670不僅是一個保護設備，還是一個集控制、監(jiān)視于一體的智能化電子設備。它可以對電力系統(tǒng)進行監(jiān)視，包括二次系統(tǒng)監(jiān)視和頻率保護功能。
RED670還具有一個服務端口，用于監(jiān)視和調整軟件變量，支持RED670的通信，并提供配置、校準、故障排除和報警/停機監(jiān)控等功能。
總的來說，RED670是一款功能強大、性能穩(wěn)定的保護設備，它的使用可以提高電力系統(tǒng)的可靠性，并提供集成的保護、控制和監(jiān)視解決方案。

【英文介紹】
RED670 is a line differential protection device, which is part of the Relion family of products designed to meet the high requirements of power system protection.
Key features and functions of the RED670 include:
Suitable for power systems of all voltage levels, it can be used to protect, control and monitor overhead lines and cables, including heavy duty lines and multi-terminal lines.
Support single-phase, two-phase and three-phase tripping mode, and provide phase differential protection, with excellent sensitivity and phase selection function.
It can be adapted to different network structures, including impedance grounded or directly grounded systems, and can also be used to protect a variety of networks, including series compensation systems.
With backup distance protection function, when the communication channel is interrupted, it can be used as a selective backup protection.
Equipped with current protection function, can effectively detect the fault current in the line, but also has voltage protection function, can monitor the voltage change on the line.
In addition, RED670 is not only a protection device, but also an intelligent electronic device that integrates control and monitoring. It can monitor the power system, including secondary system monitoring
and frequency protection functions.
RED670 also has a service port for monitoring and adjusting software variables, supports RED670 communication, and provides configuration, calibration, troubleshooting, and alarm/shutdown monitoring.
Overall, the RED670 is a powerful and stable protection device that can be used to improve the reliability of power systems and provide integrated protection, control and monitoring solutions.
