Switch operator for switchgear

摘要

A switch operator is provided that is capable of field retrofit installation by being affixed to manually operable switchgear to provide power operation thereof. The switch operator includes provisions for connecting the drive output of the switch operator to a switch-operating shaft of a manually operable switch within the switchgear. The drive output provisions of the switch operator include a selectively operable decoupling arrangement which is operable without the need for tools. The switch operator also provides for manual operation without the need for decoupling or the disconnection of parts. The drive output of the switch operator is defined at an output shaft of a motor/gear train. Two coaxially arranged levers, an operator drive lever and a switch drive lever, are selectively coupled to transmit the drive output of the switch operator to the switch-operating shaft. A manual drive connection is affixed to the output shaft which is rotatable to provide manual operation via a handle. The handle may be the same handle that is utilized for manual operation of the switch without the provision of the switch operator.
