实现开关站的最优控制和安全操作

REC670 - 最高的灵活性与性能

REC670 智能微机保护装置为各种类型开关设备（AIS/GIS）

及各种接线方式的开关设备提供了用户自定义或预配置的控制

方案。用户自定义的RET670  1MRK004816-AC按照您的需要为您提供完全自由

的功能选择。因为REC670 基本功能已经选择并已配置在装置

里，故预配置REC670 只需进行简单的操作即可投入使用。如

果需要,您也可以很容易地增加REC670装置的可选功能，以满

足您开关站特殊的配置需要。

RET670  1MRK004816-AC使得用户能通过变电站自动化系统实现有载调压的手

动控制。用户可同时在一台REC670 中配备先进的变压器分接

头自动调节（AVC）功能，因此对于站内变压器保护未配置相

应自动电压控制功能时，可不用安装专门的电压控制设备。

RET670  1MRK004816-AC 突出的开入开出容量能够只用一个装置实现多个间隔的控制。例如，单台REC670装置有能力对1 1/2接线方式一串间隔里的所有设备提供测控功能，并包括所有断路器的失灵保护。因此，REC670能够用在包含不同保护和控制系统的任何电压等级的任何变电站，简化系统设计并有效地降低成本。

使用单台REC670可以实现对1 ½接线方式一整串所有开关设备的控制 REC650在单母线单断路器接线方式的应用

Relion® 670系列微机保护装置还支持基于IEC61850-9-2 LE标准的过程总线的同步采样值通讯以代替了过程层和二次系统之间的传统硬接线。该功能使变电站实现了全新的设计，例如，使用传感器技术的解决了如CT饱和和电磁干扰引起的相关问题。此外，采用光纤代替传统的硬接线变电站的改造和维护更有效率。

670系列微机保护装置支持在同一装置上同时采用传统硬接线和基于IEC61850-9-2 LE标准的光纤通讯。这使从模拟量的传统硬接线到同步采样测量值的光纤通讯的改造可以按部就班地分步完成。

Realize the optimal control and safe operation of the switching station

REC670 - Maximum flexibility and performance

REC670 Intelligent microcomputer protection device for various types of switchgear (AIS/GIS) And a variety of wiring switchgear provides user-defined or pre-configured control

Plan. The custom RET670 1MRK004816-AC gives you complete freedom according to your needs Function selection. Because the REC670 basic features have been selected and configured in the deviceTherefore, the pre-configured REC670 can be put into use with simple operations. Such as

If desired, you can also easily add optional features to the REC670 device to full capacity Meet the special configuration needs of your switch station.

RET670 1MRK004816-AC enables users to implement on-load voltage regulation through substation automation systems

Motion control. Users can simultaneously install advanced transformer tapping in one REC670

Head automatic regulation (AVC) function, so no phase is configured for in-station transformer protection

When the automatic voltage control function is required, it is not necessary to install special voltage control equipment.

The RET670 1MRK004816-AC's outstanding on-off capacity enables multiple intervals to be achieved with only one device

Control. For example, a single REC670 device has the ability to connect a string of 1 1/2 wiring modes at intervals

All equipment in the test and control function, and including all circuit breaker failure protection. Due to the

Therefore, the REC670 can be used at any voltage level that includes different protection and control systems

For any substation, simplify system design and effectively reduce costs.

A single REC670 can be used to control a whole string of all switchgear in 1 ½ connection mode. REC650 is applied in a single bus and single circuit breaker connection mode

The Relion® 670 Series microcomputer protection devices also support synchronous sampling value communication based on the IEC61850-9-2 LE standard process bus instead of the traditional hard wiring between the process layer and the secondary system. This capability enables the substation to achieve completely new designs, for example, using sensor technology to solve related problems such as CT saturation and electromagnetic interference. In addition, the use of fiber optics instead of traditional hard-wired substations is more efficient for renovation and maintenance.

The 670 Series microcomputer protection device supports both conventional hardwired and IEC61850-9-2 LE standard optical fiber communication on the same device. This enables the transformation of optical fiber communication from traditional hardwiring of analog quantities to synchronous sampling measurements to be completed in a step-by-step manner.
