CONTACT STRUCTURE OF AXIAL MAGNETIC FIELD TYPE VACUUM INTERRUPTER

摘要

The present invention relates to an electrode structure of an axial magnetic field type vacuum interrupter, and more particularly, to an electrode structure of an axial magnetic field type vacuum interrupter having a cup shape, in which a groove is formed at a central portion of a contact point, so that an arc is prevented from being generated when current is blocked and magnetic flux density in an axis direction generated in an area between the central portion and an outer portion of the contact point is relatively higher than that in the central portion. An electrode structure of an axial magnetic field type vacuum interrupter according to the present invention includes an external conductor including a first bottom portion, a first side portion having a cylindrical shape and a plurality of first slits formed on the fist side portion and having a predetermined gradient with respect to the first bottom portion; an internal conductor including a second bottom portion, a second side portion having a cylindrical shape and a plurality of second slits formed on the second side portion and inclined in an opposite direction of the predetermined gradient of the first slits; and a contact plate coupled to a top surface of the external conductor.;COPYRIGHT KIPO 2014
