Current transformer operating state monitoring system

The utility model provides a current transformer operating state monitoring system, which comprises a monitoring unit, a processing unit, an output unit and a dispatching center, wherein the monitoring unit is used for monitoring operating parameters of a current transformer, the processing unit is connected with an output end of the monitoring unit, the output unit is connected with the processing unit, the dispatching center is connected with the processing unit; the monitoring unit at least comprises two temperature sensors, a vibration sensor arranged on the current transformer, a current detection module connected to a secondary side of the current transformer, and a voltage detection module connected to a secondary side of the current transformer; and one temperature sensor is arranged on the current transformer, the other temperature sensor is arranged in the environment where the current transformer is positioned and keeps a set distance from the current transformer. The current transformer operating state monitoring system can carry out real-time monitoring on operating state of the current transformer comprehensively and fully, can accurately judge whether a fault of the current transformer is caused by open circuit of the secondary side or other reasons, and ensures the continuous and stable operation of power system.
