產(chǎn)品細節(jié)說明：REA101-AAA ABB 弧光故障保護系統(tǒng)主模塊
- 可調節(jié)的三相過流或兩相和中性點過電流狀態(tài)監(jiān)視功能，提高弧光故障檢測可靠性。
- 內(nèi)置自檢系統(tǒng)，監(jiān)視運行電壓、主模塊和擴展模塊之間布線的完好性，以及主模塊間的光纖連接。
- 故障檢測后，系統(tǒng)將閉鎖模塊防止誤動作 。
- 利用環(huán)型或輻射型光纖傳感器，或者透鏡傳感器進行光檢測。
- 提供兩個RJ45端口，每個端口最多支持5個擴展模塊。
- 通過光纖連鏈路通信或REA105中間擴展模塊，可實現(xiàn)多模塊互聯(lián)
REA101-AAA
產(chǎn)品詳情參數(shù) ：REA101-AAA ABB 弧光故障保護系統(tǒng)主模塊
- 型號：REA101
- 品牌：ABB
- 應用：設計用于中低壓開關柜的保護，可獨立或與REA103和REA105擴展單元一起使用。
- 主要功能：帶有兩個高速、隔電、絕緣柵雙極型晶體管（IGBT）輸出設備（HSO1和HSO2），用于斷開斷路器。此外，REA101還提供了重載繼電器輸出（TRIP3），可用作斷路器失靈保護（CBFP）跳上游斷路器或告警輸出
REA101-AAA ABB 應用領域：
REA101弧光故障保護系統(tǒng)的設計允許快速定位故障位置，通過檢查檢測到弧光的傳感器光纖所覆蓋的區(qū)域。該系統(tǒng)的主要優(yōu)勢在于能夠迅速跳閘，并具備連續(xù)自檢傳感器光纖環(huán)路、工作電源及中央單元與擴展單元間的電纜線路的能力
Product details: REA101-AAA ABB arc fault protection system main module
Adjustable three-phase overcurrent or two-phase and neutral point overcurrent status monitoring function improves the reliability of arc fault detection.
Built in self-test system monitors the operating voltage, the integrity of wiring between the main module and expansion module, as well as the fiber optic connections between the main modules.
After fault detection, the system will lock the module to prevent misoperation.
Use ring or radiation type fiber optic sensors, or lens sensors for light detection.
Provide two RJ45 ports, each supporting up to 5 expansion modules.
Multi module interconnection can be achieved through fiber optic link communication or REA105 intermediate expansion module
Product details and parameters: REA101-AAA ABB arc fault protection system main module
Model: REA101
Brand: ABB
Application: Designed for protection of medium and low voltage switchgear, it can be used independently or in conjunction with REA103 and REA105 expansion units.
Main function: Equipped with two high-speed, isolated, insulated gate bipolar transistor (IGBT) output devices (HSO1 and HSO2) for disconnecting circuit breakers. In addition, REA101 also provides overload relay output (TRIP3), which can be used as circuit breaker failure protection (CBFP) to trip upstream circuit breakers or alarm outputs
REA101-AAA ABB application areas:
The design of the REA101 arc fault protection system allows for quick positioning of the fault location by inspecting the area covered by the sensor fiber that detects the arc light. The main advantage of this system is its ability to quickly trip and has the capability to continuously self check sensor fiber optic loops, working power supplies, and cable lines between central and expansion units
