Abstract
The present application discloses a DC vacuum interrupter. The cup-shaped contact of the vacuum interrupter is in a transverse magnetic field. The magnetic core is placed in the contact cup. The magnetic core inside the cup of the contact works with the permanent magnets outside the vacuum interrupter to generate transverse magnetic fields in multiple directions between the contacts. While the contacts are open, the arc burns and moves rapidly along the ring shaped contacts under the transverse field along the tangent line of the contacts. While the arc moves rapidly along the ring-shaped contacts, the arc column passes the permanent magnets structure and works with the magnetic core to generate multi-polar transverse magnetic field. While the arc column makes a turn, the number of the transverse fields which are cut by the arc is same with the number of the permanent magnets set.
