Description
ABB REF601 CE446BB1NH 是一款专为配电网设计的数字式馈线保护继电器。作为 Relion 605 系列的一员，该设备主要用于中压开关柜中的电缆或架空线保护。其核心任务是实时监测电力线路的电流状态，并在检测到过载、短路或接地故障时，迅速向断路器发出跳闸指令，从而保护下游昂贵的变压器和电机不受损坏。它通过高度集成的逻辑处理，确保了 controller 系统能获得准确的线路状态数据。
The ABB REF601 CE446BB1NH is a dedicated digital feeder protection relay designed for electrical distribution networks. As part of the Relion 605 series, this device is primarily used for the protection of cables or overhead lines in medium-voltage switchgear. Its core mission is to monitor the current status of power lines in real-time and promptly issue a trip command to the circuit breaker upon detecting overloads, short circuits, or earth faults, thereby shielding expensive downstream transformers and motors from damage. Through its highly integrated logic processing, it ensures that the controller system receives accurate line status data.
