ABB REC670間隔控制繼電器是一種專門設(shè)計用于電力系統(tǒng)中的設(shè)備，它在變電站自動化、電力設(shè)備保護、電力輸電線路以及配電系統(tǒng)中發(fā)揮著重要作用 。REC670主要用于監(jiān)測和控制電網(wǎng)中不同類型的間隔，例如斷路器、隔離開關(guān)等，以確保電力系統(tǒng)的安全和可靠運行 。

REC670具有以下特點：

數(shù)字輸入：具備4個DI（24VDC）。

數(shù)字輸出：具備2個DO（24VDC）。

提供2個串行端口，其中COM2可以是RS232或RS485。

設(shè)備尺寸為165 x 102 x 23毫米 。

REC670智能微機保護裝置為開關(guān)設(shè)備（AIS/GIS）及各種接線方式的開關(guān)設(shè)備提供了用戶自定義或預(yù)配置的控制方案。用戶可以根據(jù)自己的需要選擇完全自由的功能，或者使用已經(jīng)預(yù)配置的基本功能，這些功能已經(jīng)選擇并配置在裝置里，使得REC670只需進行簡單的操作即可投入使用 。

此外，REC670還具備變壓器分接頭自動調(diào)節(jié)（AVC）功能，如果站內(nèi)變壓器保護未配置相應(yīng)的自動電壓控制功能，可以不用安裝專門的電壓控制設(shè)備 。裝置對出口繼電器狀態(tài)持續(xù)監(jiān)視，有錯誤就會發(fā)出報告，確?？刂频母叨劝踩?，避免不必要的操作 。

在電力系統(tǒng)中，REC670 1MRK002814-AC設(shè)備有助于識別和管理工作緊密相關(guān)的間隔，從而最小化對變電站其余部分的影響。同時，該設(shè)備支持分布式智能電子設(shè)備（IED）的控制架構(gòu)，通過GOOSE消息和全站范圍內(nèi)的聯(lián)鎖與垂直客戶端服務(wù)器MMS通信，為電力系統(tǒng)提供高可靠性和性能的解決方案 。

The ABB REC670 interval control relay is a device specifically designed for use in power systems, where it plays an important role in substation automation, power equipment protection, power transmission lines, and distribution systems. REC670 is mainly used to monitor and control different types of intervals in the power grid, such as circuit breakers, isolation switches, etc., to ensure the safe and reliable operation of the power system.

REC670 has the following features:

Digital input: 4 DI (24VDC).

Digital output: With 2 DO (24VDC).

2 serial ports available, COM2 can be RS232 or RS485.

The device size is 165 x 102 x 23 mm.

The REC670 intelligent microcomputer protection device provides customized or pre-configured control solutions for switchgear (AIS/GIS) and switchgear with various wiring modes. Users can choose completely free functions according to their needs, or use pre-configured basic functions that have been selected and configured in the device, so that the REC670 can be put into use with simple operations.

In addition, the REC670 also has automatic transformer tap regulation (AVC) function, if the transformer protection in the station is not equipped with the corresponding automatic voltage control function, you can not install a special voltage control equipment. The device continuously monitors the status of the outlet relay and reports any errors to ensure a high level of control security and avoid unnecessary operations.

In the power system, the REC670 1MRK002814-AC device helps to identify and manage intervals where work is closely related, thereby minimizing the impact on the rest of the substation. At the same time, the device supports the control architecture of distributed intelligent electronic Devices (IEDs) and communicates with the vertical client server MMS via GOOSE messaging and site-wide interlocking, providing a highly reliable and performance solution for the power system.
