REF543KM127AAAA 饋線(xiàn)終端保護(hù)裝置 ABB REF 543
REF 543饋電端子可用于不同類(lèi)型的開(kāi)關(guān)設(shè)備,包括單母線(xiàn)、雙母線(xiàn)和雙工系統(tǒng)。
保護(hù)功能還支持不同類(lèi)型的網(wǎng)絡(luò),如隔離中性網(wǎng)絡(luò)、諧振接地網(wǎng)絡(luò)和部分接地網(wǎng)絡(luò)。應(yīng)用領(lǐng)域還包括中型三相異步電動(dòng)機(jī)以及用于無(wú)功功率補(bǔ)償?shù)牟⒙?lián)電容器組的保護(hù)和控制。除了保護(hù)、測(cè)量、控制、狀態(tài)監(jiān)控和一般功能外,REF 543饋線(xiàn)終端還配備了大量PLC功能,可將變電站自動(dòng)化所需的多種自動(dòng)化和順序邏輯功能集成到—個(gè)裝置中。
數(shù)據(jù)通信屬性包括以下通信標(biāo)準(zhǔn)通過(guò)SPA-ZC 400的SPA總線(xiàn)、LON總線(xiàn)、IEC 60870-5-103、IEC 61850、通過(guò)SPA-ZC 302的Profibus DPV1、DNP 3.0以及與更高級(jí)設(shè)備的Modbus通信。此外,LON通信和PLC功能最大限度地減少了饋線(xiàn)終端之間的硬連線(xiàn)需求。

The REF 543 feeder terminals can be used in different types of switchgear, including single bus, double bus and duplex systems.
The protection function also supports different types of networks, such as isolated neutral networks, resonant grounded networks, and partially grounded networks. Applications also include protection and control of medium-sized three-phase asynchronous motors and shunt capacitor banks for reactive power compensation. In addition to protection, measurement, control, condition monitoring and general functions, the REF 543 feeder terminal is equipped with a large number of PLC functions to integrate multiple automation and sequential logic functions required for substation automation into a single unit.
Data communication attributes include the following communication standards: SPA bus via SPA-ZC 400, LON bus, IEC 60870-5-103, IEC 61850, Profibus DPV1 via SPA-ZC 302, DNP 3.0, and Modbus communication with more advanced devices. In addition, LON communication and PLC capabilities minimize the need for hard wiring between feeder terminals.
