摘要： A high speed closing switch in a power distributor includes: a case forming an external appearance; a first electrode provided within the case and including a through hole; a second electrode having a receiving recess facing the through hole; a moving contact point member having a cylindrical portion received in the through hole so as to be put into the receiving recess and a flange portion formed at one end of the cylindrical portion; and a closing coil wound on a base of the case, wherein a damping hole is formed at receiving recess of the second electrode. When the moving contact point member put into the receiving recess approaches its final position, a damping force is applied to the moving contact point member to stably and accurately control the final position.

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.
