Abstract

Disclosed are a power transmission device for a vacuum interrupter, and a vacuum breaker having the same. The device includes: a driving link 10 coupled to an adjuster; a driven link 20 coupled to a movable electrode 5 of a vacuum interrupter; connection links 31, 35 configured to connect the driving link 10 and the driven link 20 with each other, and coupled to the driving link 10 and the driven link 20 such that an interval between the driving link and the driven link is varied; cams 41, 45 coupled to the connection links 31, 35 in a perpendicular direction; and cam guides 51, 55 having guide recesses 52, 53, 56, 57 for slidably coupling the cams 41, 45, and configured to guide the interval between the driving link 10 and the driven link 20 to be changed. Under such configurations, when the present state of the vacuum interrupter is converted into a closed state, an impact amount between the movable electrode and the fixed electrode can be reduced. This can reduce the entire time taken for the movable electrode to pass through a pre-arc region when the movable electrode is closed, thereby preventing damage of the electrodes.
