<p>The present invention relates to a ring main unit circuit breaker with a contact force adjustment device. More particularly, the present invention relates to a ring main unit circuit breaker with a contact force adjustment device capable of adjusting a contact point interval of a vacuum interrupter by a simple manual operation from the outside without releasing a ring main unit circuit breaker. The ring main unit circuit breaker with a contact force adjustment device according to an embodiment of the present invention includes: a rotation shaft; a cam to convert a rotating force of the rotation shaft into a vertical force; a power transmission pin to perform an up/down motion by the cam; a movable rod coupled with the power transmission pin; a contact force spring to provide contact pressure to the movable rod; a vacuum interrupter including an end connected to the movable rod; a drive shaft installed in a drive part; a drive link coupled with the drive shaft to be rotated; a transfer link including an end coupled with the drive link to perform the up/down motion, and capable of adjusting the length of the transfer link; and a rotation link coupled with the other end of the transfer link to provide a rotating force to the rotation shaft.</p> |
