    摘要: This specification relates to fault current limiter (FCL). More particularly, to solve problems of protecting and designing current limiting impedance in a protective coordination system, as limitations of the related art, the fault current limiter may measure heat capacity of a current limiting impedance unit (200) by detecting fault current flowing to the current limiting impedance unit and limiting the fault current flowing to the current limiting impedance unit according to the measured heat capacity, which may result in preventing the current limiting impedance unit from being damaged due to the fault current, preventing an extended accident due to the damaged current limiting impedance unit and enabling a stabilized system and line protection.

    摘要: The fault current detecting circuit includes: a current detection unit (200) that outputs a current detection signal; a first comparing circuit unit (300) that compares the current detection signal with a predetermined reference current value and outputs a first output signal; a differentiator (400) that differentiates the current detection signal to output a change slope of the current detection signal; a second comparing circuit unit (500) that compares the change slope with a predetermined reference change slope value and outputs a second output signal; a third comparing circuit unit (700) that compares the current detection signal with a predetermined current detection limit reference value and outputs a third output signal; and a trip determining unit (600) that outputs a trip control signal only when the first output signal and the second output signal are maintained to be received and the third output signal is not received.
