ABSTRACT:
A motor operator is configured to provide local and remote operation of a power line phase switch. The motor operator has its components individually enclosed in a component enclosure and further enclosed in a main enclosure, allowing isolation and protection of the components from the environment and operators. A gear box includes a worm gear reducer submersed in oil providing a no maintenance gear train that makes continuous braking unnecessary by virtue of the inherently self-locking nature of the worm gear. The motor operator also includes a plurality of limit and auxiliary switches providing local and remote indication of switch position. The switches are each independently adjustable using cam adjustment collars. The overall configuration of the motor operator provides safe, reliable and cost effective phase switch operation.
