Vacuum interrupter and driving method therefor

A method of driving a vacuum interrupter, the method comprising:

• respectively operating, by a controller, a first driving part and a second driving part, respectively connected to a first and a second movable electrodes, to move the first and second movable electrodes in forward/backward directions;
• respectively moving the first and second movable electrodes within a vacuum interrupter by the first and second driving parts;
• and
• contacting a first and a second movable contacts each other according to movements of the first and second movable electrodes, the first and second movable contacts being respectively attached to first ends of the first and second movable electrodes,
• wherein the controller adjusts moving times and moving speeds of the first and second movable electrodes by adjusting times of applying current to the first and the second driving parts.

A method of driving a vacuum interrupter, the method comprising:

• respectively applying current to contact coils of a first and a second driving parts to respectively move a first and a second movable electrodes within a vacuum interrupter by a controller;
• respectively moving the first and second movable electrodes by using magnetic force of the contact coils generated by the applied current so that a first and a second movable contacts respectively attached to first ends of the first and second movable electrodes contact each other;
• and
• respectively applying current to separation coils of the first and second driving parts just before the first and second movable contacts contact each other so that moving speeds of the first and second movable electrodes decreases,
• wherein the controller adjusts moving times and moving speeds of the first and second movable electrodes by adjusting times of applying current to the first and the second driving part.
