摘　　要：设计了一种新型的变电站通道备用及监测装置,通过对通道监测,可预判通道故障类别,同时实现站内重要遥信量,如事故总信号变位的预警,实现通道备用,有效解决了通信中断需要有人值守的问题。试运行结果表明,该装置响应速度快、预警准确,为无人值守变电站的自动化运行提供了有力支持。A new spare and monitoring device of the remote channel in substation was proposed. This device can recognize the fault type and transmit the remote signal by monitoring the channels, such as the wanting of substation general fault signal change. And it can be a spare channel as well. It effectively solved the problem of the communication interrupt needed someone on duty. The test result shows its good responsiveness and performance.
