REA101弧光故障保护系统的设计允许快速定位故障位置，通过检查检测到弧光的传感器光纤所覆盖的区域。该系统的主要优势在于能够迅速跳闸，并具备连续自检传感器光纤环路、工作电源及中央单元与扩展单元间的电缆线路的能力
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
