Control module and fault current limiter with function of opening and closing

PURPOSE: A control module and a fault current limiter are provided to improve the reliability of the fault current limiter by securing the smooth operation of the fault current limiter regardless of the amount of fault currents. CONSTITUTION: A trigger device(100) classifies a fault current and a steady state current into different paths. A first switch(110) is serially connected to the rear end of the trigger device. A fixing unit(150) fixes the open or closed state of the first switch. A driving unit(120) opens the contact point of the first switch by using the repulsive power by the fault current. The driving unit includes the first coil and a repulsive plate. The repulsive plate moves with the repulsive power by the fault current. A control module(180) drives the fixing unit in order to fix the open or closed state of the first switch.
