REX521GHHPSH51G饋線(xiàn)和電動(dòng)機(jī)保護(hù)繼電器詳情介紹
REX 521用途廣泛，可用在輸、配電網(wǎng)絡(luò)上作保護(hù)、控制和監(jiān)視，可用于不同電壓等級(jí)的中性點(diǎn)接地、小電阻接地、中性點(diǎn)不接地和諧振接地的網(wǎng)絡(luò)。該裝置既適用于輻射網(wǎng)也用于環(huán)狀網(wǎng)，既適用于單端供電系統(tǒng)也可用于多端供電的線(xiàn)路。
該保護(hù)繼電器采用多處理器技術(shù)實(shí)現(xiàn)其高性能。數(shù)字信號(hào)處理芯片(DSP)配合高性能的CPU以提高繼電器的測(cè)量精度，加快保護(hù)響應(yīng)速度。人機(jī)界面(繼電器面板上的 LCD 和后臺(tái)整定工具軟件的界面)提供了多幅畫(huà)面和詳盡的幫助信息，方便用戶(hù)使用。在繼電器的軟件和硬件方面，都大量使用了現(xiàn)代技術(shù)。該繼電器是 ABB 變電站自動(dòng)化產(chǎn)品系列的成員，在功能和使用靈活性方面有了更新的發(fā)展，這源于電子和電氣領(lǐng)域最新技術(shù)在該產(chǎn)品上的應(yīng)用。
REX 521 has a wide range of applications and can be used for protection, control, and monitoring in transmission and distribution networks. It can be used for neutral point grounding, low resistance grounding, neutral point ungrounded, and resonant grounding networks of different voltage levels. This device is suitable for both radial and circular networks, as well as single ended power supply systems and multi ended power supply lines.
This protective relay adopts multi processor technology to achieve its high performance. The digital signal processing chip (DSP) is combined with a high-performance CPU to improve the measurement accuracy of relays and accelerate protection response speed. The human-machine interface (LCD on the relay panel and the interface of the background tuning tool software) provides multiple images and detailed help information, making it convenient for users to use. Modern technology is extensively used in both software and hardware aspects of relays. This relay is a member of ABB's substation automation product line, with updated developments in functionality and flexibility, stemming from the application of the latest technologies in the electronics and electrical fields in this product.
REX 521 除保護(hù)功能外，還提供了以下功能： 用于監(jiān)測(cè)用戶(hù)網(wǎng)絡(luò)的全面的測(cè)量功能； 為了精確捕捉和分析故障，集成了高采樣率的故障錄波模塊就地 / 遠(yuǎn)方斷路器控制； 可配置多輪次自動(dòng)重合閘； 斷路器狀態(tài)監(jiān)測(cè)； 可測(cè)量電壓或電流的總諧波畸變率（THD）以用于電能質(zhì)量監(jiān)視； 全中文的界面標(biāo)識(shí)和顯示信息。 | In addition to protection functions, REX 521 also provides the following functions: Comprehensive measurement functions for monitoring user networks; In order to accurately capture and analyze faults, a high sampling rate fault recording module is integrated for local/remote circuit breaker control; Can be configured with multiple rounds of automatic reclosing; Circuit breaker status monitoring; Total harmonic distortion (THD) of measurable voltage or current for power quality monitoring; Full Chinese interface identification and display information. |
