功能:接地故障继电器UFC765AE102是一个连接到电流的二元继电器待保护对象的变压器。UFC765AE102可以测量接地故障电流通过剩余电流连接中的一组三相电流互感器或窗口式堆芯平衡电流互感器。当使用堆芯平衡电流互感器时,应确保电流互感器的重复性在高接地故障电流下也是足够的。什么时候发生接地故障时,继电器发出报警信号,使断路器跳闸或启动外部自动重合闸继电器,取决于的应用程序和配置转发。
当UFC765AE102通电电流超过设定值时。低设定级的启动值I0>,接地故障继电器启动。当在特定时间运行时,设定运行时间t>或在IDMT时计算出的操作时间t>,到期时,继电器工作。以同样的方式高置位阶段一旦其设定的起始值就开始超过I0>>,并且当机组运行时时间t>>到期,继电器工作。
The ground fault relay UFC765AE102 is a transformer connected to a current binary relay for the object to be protected. UFC765AE102 can measure ground fault current through a set of three-phase current transformers or window type core balanced current transformers in the residual current connection. When using core balanced current transformers, it should be ensured that the repeatability of the current transformer is also sufficient at high ground fault currents. When a ground fault occurs, the relay sends an alarm signal to trip the circuit breaker or activate an external auto reclosing relay, depending on the application and configuration forwarding.
When the power on current of UFC765AE102 exceeds the set value. The ground fault relay is activated when the starting value of the low setting stage is I0>. When operating at a specific time, set the operating time t>or the operating time t>calculated at IDMT. When it expires, the relay operates. In the same way, the high set stage starts to exceed I0>>once its set starting value is set, and when the time t>>expires while the unit is running, the relay operates.
