The alarm will prompt the operator to find the cause of overheating in time to avoid the situation where the insulation layer of the cables in the shielding device is damaged due to excessive temperature; the current sensor is used to detect the current on the metal iron frame to which the cables are tied. After detecting the overload current or short-circuit current, it is judged that the cable has external damage causing current leakage, and a signal will be sent to the control module.
