摘　　要：控制回路对于整个变电站的安全稳定运行具有重要的作用。针对变电站实际运行中,存在有控制回路已经断线,但是监控后台没有报出控制回路断线信号的情况,结合控制回路特点,增加跳合闸线圈监视继电器,有效地消除了这一缺陷,提高了继电保护装置的动作可靠性。The control loop plays an important role in the safe and stable operation of the entire substation.In view of the actual operation of substations,there is a control circuit has been broken,but the monitoring background did not report the control circuit broken signal.Combining with the characteristics of the control loop,a monitoring relay with tripping coil was added,which effectively eliminated this defect and improved the operation reliability of the relay protection device.

关 键 词：控制回路 继电器 控回断线
