Contact arrangement for vacuum interrupter and vacuum interrupter using the contact arrangement

摘要

In a contact arrangement and a vacuum interrupter using the contact arrangement, the contact arrangement includes: a hollow cylindrical contact carrier on one end surface of which a contact plate is attached; a plurality of first slits formed on the contact carrier from the one end surface of the contact carrier; and a plurality of second slits formed on the contact carrier from each predetermined point of midway through an axial direction of the contact carrier, each of the first and second slits being tilted with respect to the axial direction of the contact carrier, a coil portion being formed on a portion of the hollow cylindrical contact carrier between each of the first and second slits and an adjacent one of the first and second slits and a longitudinal magnetic field being formed along the axial direction of the contact carrier by a current flowing on the coil portion. <IMAGE>
