F650-N-F-L-F-2-G-1-HI-P-6E 继电装置

F650-N-F-L-F-2-G-1-HI-P-6E是一个继电装置。

继电装置通常用于监测电力系统中的电气参数，并在出现异常情况时自动采取相应措施以保护电力系统的设备。这种装置由各种传感器、逻辑电路和执行机构组成，可以检测电力系统的电流、电压、频率等参数，并将这些参数与正常值进行比较。如果发现异常，就会触发执行机构采取相应的保护措施。

具体到F650-N-F-L-F-2-G-1-HI-P-6E这款继电装置，它有以下特性：

连接远程CAN总线I/O模块：其后部最多可增加两个通信卡，其中一个端口用于连接远程CAN总线I/O模块（CIO模块）。当内部可用的最大I/O数量不足以满足特定应用的需求时，可以使用CIO模块将I/O数量增加一倍。此外，CIO模块还允许该装置监控位于远程位置的信号，从而显著节省了安装成本。

增加和共享数字点状态信息：通过远程I/O功能，F650-N-F-L-F-2-G-1-HI-P-6E可以在其他符合IEC61850的IED或控制器之间共享数字点状态信息。

故障检测和零序电流变化监控：在电流互感器（CT）出现异常行为或相位损失的情况下，该装置能够检测零序电流的变化，并启动CT故障引诱事件，以及用于阻止关键保护功能的输出。

二次谐波检测：该装置提供二次谐波检测功能，这有助于屏蔽敏感元件，特别是在变压器通电期间。

跳闸电路监控：它可以用于监测断路器跳闸和闭合线圈及电路的完整性，以及监控蓄电池电压水平。

F650-N-F-L-F-2-G-1-HI-P-6E is a relay device.

The relay device is usually used to monitor the electrical parameters in the power system and automatically take corresponding measures to protect the power system equipment when abnormal conditions occur. This device is composed of various sensors, logic circuits and actuators, which can detect the current, voltage, frequency and other parameters of the power system, and compare these parameters with normal values. If an exception is found, the actuator will be triggered to take appropriate protection measures.

Specifically to the F650-N-F-L-F-2-G-1-HI-P-6E relay device, it has the following characteristics:

Connect to remote CAN bus I/O modules: Up to two communication cards CAN be added to the rear, one of which is a port for connecting to remote CAN bus I/O modules (CIO modules). When the maximum number of I/ OS available internally is not enough to meet the needs of a particular application, the CIO module can be used to double the number of I/ OS. In addition, the CIO module allows the unit to monitor signals located in remote locations, resulting in significant savings in installation costs.

Add and share digital point status information: With remote I/O, the F650-N-F-L-F-2-G-1-HI-P-6E can share digital point status information between other IEC61850-compliant IEDs or controllers.

Fault detection and zero-sequence current change monitoring: In the event of abnormal behavior or phase loss of the current transformer (CT), the device is capable of detecting changes in zero-sequence current and initiating CT fault lure events, as well as outputs to block critical protection functions.

Second harmonic detection: The unit provides second harmonic detection, which helps shield sensitive elements, especially during transformer power-on.

Tripping circuit monitoring: It can be used to monitor the integrity of breaker tripping and closing coils and circuits, as well as to monitor battery voltage levels.
