POWER DRIVEN GROUP OPERATED CIRCUIT DISCONNECT APPARATUS FOR OVERHEAD ELECTRIC POWER LINES

摘要

ABSTRACT OF THE DISCLOSUREA group operated circuit disconnect apparatusfor overhead electric power lines has a base in the formof a box-like housing which mounts on a pole, an uprightshaft extends through the housing, and a transverse shaftalso extends through the housing. A linkage is mountedon the shafts in the housing so that axial rotation ofthe transverse shaft axially rotates the upright shaft,and this causes three circuit disconnect switches mountedon the housing to be moved simultaneously between closedpositions and open positions, or vice versa. An electricmotor driven screw and nut drive subassembly for thetransverse shaft is mounted in the housing; and the endsof the housing have removable closure plates for accessto the linkage and for removal of the subassembly.
