摘要： A vacuum interrupter. The vacuum interrupter comprising at least one anode side contact blade, at least one cathode side contact blade, at least one anode side conducting rod, at least one a cathode side conducting rod, a shielding case and an outer magnet, wherein the shielding case covers the at least one anode side contact blade, the c at least one anode side contact blade, the at least one anode side conducting rod and at least one cathode side conducting rod; and the outer magnet covers the shielding case. According to the vacuum interrupter, the outer magnet is arranged to generate a fixed first longitudinal magnetic field in the interelectrode area of the at least one anode side contact blade and the at least one cathode side contact blade, contraction of arcs during current breaking can be alleviated, the arcs are in a diffusion state, and ablation of the contact in the arcing process is reduced, and breaking capacity of a vacuum circuit breaker is guaranteed.
