Electric switchboard cell having a positioning drive for a movably arranged switchgear and locking device for switchboard cell door

Image Number 2 for United States Patent #4754367.

An electric switchboard cell includes a positioning drive with a threaded spindle for a movably arranged switchgear and a door. At the bottom of the switchboard cell, a latch lever is pivoted which has a cam with which a guiding member of the positioning drive cooperates. The latch lever is pivoted by means of the cam, when the disconnect position of the switchgear is reached, into a position in which its locking projection is disengaged from a lock bracket attached to the door. The lock bracket is attached pivotally to a pillow block mounted to the door and can be disengaged from the locking projection by authorized personnel for defeating the locking device, e.g., for servicing.
