Provided is a novel
vacuum interrupter structure. The novel
vacuum interrupter structure mainly comprises a
vacuum tube and a double-repulsion disc, the double-repulsion disc is located at the lower end part of the
vacuum tube, a moving contact of the
vacuum tube and a repulsion coil panel of the double-repulsion disc are connected through a conducting rod, the moving contact and the repulsion coil panel simultaneously move under stress, and the novel
vacuum interrupter with a auto-breaking function is formed. When a
system has a
short circuit fault, field current is charged to the repulsion coil panel through the conducting rod by
short circuit current, a
magnetic field is generated, a repulsion
copper disc forms induction
eddy current under the effect of the
magnetic field, the direction of the induction
eddy current is opposite to the direction of the field current, a huge electromagnetic repulsion is generated between the repulsion
copper disc and the repulsion coil panel, a repulsion coil drives the conducting rod to pull the moving contact for rapid switch-off, and the goal of rapid
line switching is achieved. According to the vacuum
interrupter, the auto-breaking function is provided, the immediacy is high, the motion speed is high, and the overall structure is more compact.
