REX521BBHGLB01C 電動(dòng)機(jī)保護(hù)繼電器

ABB的REX521系列中的REX521BBHGLB01C是一款高性能、高可靠性的饋線(xiàn)和電動(dòng)機(jī)保護(hù)繼電器。這款產(chǎn)品集合了保護(hù)、測(cè)量、錄波、監(jiān)視和控制功能，適用于中性點(diǎn)不接地系統(tǒng)、中性點(diǎn)直接接地系統(tǒng)、小電阻接地系統(tǒng)和諧振接地系統(tǒng)中的中壓饋線(xiàn)及大中型三相交流電動(dòng)機(jī)的保護(hù)。

具體來(lái)說(shuō)，REX521BBHGLB01C的保護(hù)功能包括相間過(guò)流、接地、過(guò)電壓、低電壓、電機(jī)各種保護(hù)及頻率保護(hù)元件等。此外，它還具有電流、電壓、頻率、有功和無(wú)功功率、功率因數(shù)、電能等測(cè)量功能，以及斷路器觸頭電器磨損監(jiān)測(cè)、跳閘回路監(jiān)視等功能。

REX521BBHGLB01C內(nèi)部集成了一個(gè)故障錄波模塊，有五個(gè)模擬量輸入通道和多達(dá)十六個(gè)開(kāi)關(guān)量通道，以COMTRADE格式完整記錄故障狀態(tài)。同時(shí)，它還具有自診斷功能，可以確定繼電器的完好狀況，如果繼電器不能正常工作，它可以在繼電器無(wú)法正常工作之前發(fā)出告警信號(hào)，同時(shí)閉鎖所有保護(hù)功能和輸出接點(diǎn)。

這款保護(hù)繼電器具有兩個(gè)獨(dú)立的通訊端口，RS485接口可以支持MODBUS RTU/ASCII、DNP 3.0及SPA協(xié)議，通訊波特率最大可至19.2Kpbs。光纖口支持IEC60870-5-103、MODBUS RTU/ASCII、DNP3.0、LON及SPA協(xié)議。這些端口可以方便用戶(hù)簡(jiǎn)易快速地接入各類(lèi)廠(chǎng)家的后臺(tái)系統(tǒng)。

REX521BBHGLB01C的人機(jī)界面包括4*8字符液晶顯示及方向?qū)Ш芥I盤(pán)，三個(gè)LED狀態(tài)指示和8個(gè)自由定義的指示燈。此外，這款保護(hù)繼電器還專(zhuān)門(mén)為中國(guó)市場(chǎng)推出了具有全中文操作界面的配置方案，可分別適用于饋線(xiàn)和電動(dòng)機(jī)保護(hù)的需要。

REX521BBHGLB01C 電動(dòng)機(jī)保護(hù)繼電器

The REX521BBHGLB01C in ABB’s REX521 family is a high-performance, highly reliable feeder and motor protection relay. This product combines protection, measurement, wave recording, monitoring and control functions for neutral ungrounded systems, neutral direct grounding systems, small resistance grounding systems and resonant grounding systems of medium voltage feeders and large and medium-sized three-phase AC motor protection.

Specifically, the protection functions of REX521BBHGLB01C include phase-to-phase overcurrent, grounding, overvoltage, low voltage, various motor protection and frequency protection elements. In addition, it also has current, voltage, frequency, active and reactive power, power factor, electrical energy and other measurement functions, as well as circuit breaker contact electrical wear monitoring, tripping circuit monitoring and other functions.

The REX521BBHGLB01C integrates a fault recording module with five analog input channels and up to sixteen switching channels to record the fault status completely in COMTRADE format. At the same time, it also has a self-diagnostic function, can determine the good condition of the relay, if the relay does not work properly, it can send an alarm signal before the relay does not work properly, while locking all protection functions and output contacts.

This protective relay has two independent communication ports, RS485 interface can support MODBUS RTU/ASCII, DNP 3.0 and SPA protocols, communication baud rate up to 19.2Kpbs. The fiber port supports IEC60870-5-103, MODBUS RTU/ASCII, DNP3.0, LON, and SPA protocols. These ports can facilitate users to access the background system of various manufacturers easily and quickly.

The human-machine interface of the REX521BBHGLB01C includes a 4*8 character LCD display and directional navigation keyboard, three LED status indicators and eight freely defined indicators. In addition, this protective relay has been specially introduced for the Chinese market with a fully Chinese operating interface configuration scheme, which can be adapted to the needs of feeder and motor protection respectively.
