[0014] 1. Through the setting of the power taking module, the current monitoring module and the temperature sensing monitoring module, during the monitoring of the cable, the first shell and the second shell are opened, and the cable is placed between the first arc groove and the second arc groove, and the square groove on the connecting piece is inserted into the surface of the square block to complete the locking and fixing of the first shell and the second shell. Since the CT power taking module and the current monitoring module fit the surface of the cable, the electromagnetic energy of the AC power line can be collected and converted into electrical energy to provide working power for the current monitoring module and the temperature sensing monitoring module. When the power frequency current passing through the object to be measured is 0.5A~1A, the sensor can start working and store excess electrical energy through intelligent energy storage technology to ensure continuous operation of the sensor. During the operation of the current monitoring module and the temperature sensing monitoring module, the cable temperature and current can be monitored online according to the set acquisition frequency.
