摘要： An apparatus for quickly determining a fault in an electric power system includes a current transformer, a current determination unit and a fault determination unit. The current transformer detects current supplied to the electric power system and outputs a current detection voltage. The current determination unit respectively compares the current detection voltage, the first-order differential voltage of the current detection voltage and the second-order differential voltage of the current detection voltage with predetermined first, second and third reference voltages. The fault determination unit determines whether a fault occurs based on the compared result of the current determination unit and generates a trip signal when it is determined that the fault has occurred.

摘要： A vacuum interrupter includes a fixed contact and a movable contact ; a driving unit including a main shaft and a plurality of links interlocked with the main shaft, to supply a driving force to open and close the vacuum interrupter; a power transmission unit to transmit a driving force of the driving unit to the movable contact; an over-current relay to detect a fault current and to output a trip signal to break a large-scaled current conduction; a trip unit to generate and transmit a mechanical operation force to the driving unit when a trip signal is output from the over-current relay; and a Thomson drive including a Thomson coil and a repulsive plate, to rotate the main shaft to an opening position or to transmit the trip signal to the trip unit, to promptly breaking a fault current.
