High voltage vertical break disconnect switch with planetary gear reduction switch drive mechanism

A high voltage vertical break disconnect switch comprising:

• three perpendicular cylindrically-shaped insulators mounted in operative arrangement on a longitudinal beam, one of the perpendicular cylindrically-shaped insulators being rotatable axially and the other of the perpendicular cylindrically-shaped insulators being stationary,
• a prime mover including a drive shaft in operative rotational drive arrangement with the one rotatable perpendicular cylindrically-shaped insulator,
• an elongated movable switch-blade assembly in operative arrangement with the prime mover drive shaft, the elongated movable switch-blade assembly including an elongated switch blade for electrically opening and closing the high voltage vertical break disconnect switch,
• the elongated movable switch-blade assembly including a hinge assembly configured to movably support a proximal end of the elongated switch blade, the hinge assembly in electrically conductive relationship with the elongated switch blade,
• a movable link assembly in operative arrangement with the hinge assembly for rotating the elongated switch blade from a closed electrically conductive position to an open electrically non-conductive position,
• a planetary gear reduction drive assembly including a planetary gear reduction switch drive mechanism having at least one stage,
• the planetary gear reduction switch drive mechanism including at least a two-piece crank shaft assembly mounted coaxially and in operative rotational relationship with the rotatable perpendicular cylindrically-shaped insulator,
• the planetary gear reduction switch drive mechanism in operative rotational drive arrangement with the movable link assembly,
• the planetary gear reduction switch drive assembly operatively supported by and housed within a live base assembly having oppositely disposed side plates
• a first of the stationary perpendicular cylindrically-shaped insulators in operative supportive relationship with the base assembly,
• the movable link assembly mounted in operative arrangement between the two-piece crank shaft assembly and the hinge assembly,
• whereby loads to be transmitted between the prime mover drive shaft and the movable link assembly are reduced by the planetary gear reduction drive assembly.
