REC670 传输变压器保护 用于电网中不同类型的托架的控制、保护和监测

品牌：ABB

型号：REC670

REC670用于电网中不同类型的托架的控制、保护和监测。lED特别适用于控制系统中的应用61850-8-1 ed1或ed2站总线的特点可以充分利用rec670。它用于全站联锁viaGOOSE消息和垂直客户机-服务器MMS与本地站或远程SCADA操作员工作场所的通信。这支持在所有机柜中具有分布式控制led的架构，对可靠性要求很高。通过内置的prp特性获得冗余通信，该特性可用于星型或环总线架构。REC670可用于所有电压水平。适用于任何类型开关柜中所有设备的控制安排。

控制是从远程(SCADA/站)通过lEC 61850-8-1 Ed1或Ed2站通信或从内置的多显示本地html执行。实施网络安全措施，确保系统安全自主运行保护和控制功能，即使同时发生网络攻击。适用于所有常见类型的开关柜安排，控制联锁有不同的预配置。一个REC670控制lED可用于单托架或多托架应用。控制操作是基于先选择后执行的原则来给出最高的可能的安全。有同步检查功能，以协助最佳断路器关闭在正确的实例同步和异步网络。

多种保护功能可灵活使用，适用于不同的站型和母线布置。来满足用户的应用需求，REC670的特点，例如，多达六个瞬时相位和接地过流功能，四步定向或非定向延迟相和接地过流功能，热过载和频率功能，两步欠压和过压功能，自动重合闸功能和几种不同的测量功能。这与可以显示一个或多个页面的多显示本地html一起，允许使用REC670在变电站中保护和控制多达六个托架。

Model: REC670

The REC670 is used for the control, protection and monitoring of different types of brackets in the power grid. Leds are particularly suitable for applications in control systems 61850-8-1 ed1 or ed2 station bus features can take full advantage of rec670. It is used for site-wide interlocking viaGOOSE messages and vertical client-server MMS Communication with local stations or remote SCADA operator workplaces. This supports an architecture with distributed control leds in the organic cabinet, with high reliability requirements.Redundant communication is achieved through the built-in prp feature, which can be used in star or ring bus architectures. The REC670 can be used at all voltage levels. Suitable for control of all equipment in any type of switchgearArrange.

Control is performed from remote (SCADA/ station) via lEC 61850-8-1 Ed1 or Ed2 station communication or from built-in multi-display local html. Implement network security measures to ensure safe and autonomous system operation Protect and control functionality even if simultaneous cyber attacks occur. Suitable for all common types of switchgear Arrangements for control interlocks have different preconfigurations. A REC670 control lED is available Single or multi-bracket applications.

 The control operation is based on the principle of select first, execute later to give the highest Possible safety. There is a synchronous check function to assist in optimum circuit breaker closure in the right instance Synchronous and asynchronous networks.

A variety of protection functions can be used flexibly for different station types and bus arrangements. 

To meet user application requirements, the REC670 features, for example, up to six instantaneous phases and ground Overcurrent function, four-step directional or non-directional delay phase and ground overcurrent function, thermal overload and frequency function, two-step undervoltage and overvoltage function, automatic reclosing function and several different measurement functions. This, along with multi-display native html that can display one or more pages, allows up to six bays to be protected and controlled in a substation using REC670.
