The vacuum circuit breaker uses vacuum as an arc extinguishing medium, when contacts are separated, an arc is generated between the contacts, and the arc is extinguished rapidly in a vacuum environment, so that current is cut off, and when a movable contact and a fixed contact are separated under the action of an operating mechanism, the arc is generated between the contacts. The contact surface volatilizes steam at high temperature, and because the contact is designed into a special shape, a magnetic field is generated when current passes through, and the electric arc rapidly moves along the tangential direction of the contact surface under the action of the magnetic field. After condensing part of the metal vapor on the metal cylinder, the electric arc is extinguished when the natural zero crossing occurs, and the medium strength between the contacts is quickly restored.
