REX521GHHPSH51G 是一种保护继电器只,专门设计用于中压网络中的保护、控制、测量和监控功炮。其典型应用包括输入和输出馈线以及变电站保护,此外,该电器还可以用作电力变压器的后备保护和高压电动机的保护,
该继电鑾基于多处唑器只环境,并具有硬件版本,可以使用传统的电流和电压互感密的激助输入。同时,它也支持通过输入电流和电压传感器进行激助输入,
REX521GHHPSH51G 间隔控制单元中,这些传感器通常与微处理器或控制器相连,它们负责处理传感器数据、计算距离,并根据预设的安全间距阈值采取相应措施。
The REX521GHHPSH51G is a protective relay specifically designed to protect, control, measure and monitor power guns in medium voltage networks. Typical applications include input and output feeders and substation protection. In addition, the appliance can be used as backup protection for power transformers and protection for high-voltage motors.
The relay is based on a multi-place zolator environment and has a hardware version that can use conventional current and voltage mutually sensitive excitation input. At the same time, it also supports excitation input through input current and voltage sensors,
In the REX521GHHPSH51G interval control unit, these sensors, usually connected to a microprocessor or controller, process the sensor data, calculate the distance, and take action based on a preset safe spacing threshold.
