ACTUATOR FOR REMOTE OPERATION OF A CIRCUIT BREAKER

摘要

An actuator for remote operation of a switch, such as a recloser-type circui t breaker in a power distribution network, comprises an electric mechanism suc h as an electric motor and electro-magnetic clutch mechanism which is energisable to connect the motor drive to mechanically operate the switch on command and which is otherwise mechanically disengaged from the switch such that the switch may operate freely, and a receiver arranged to receive remotely transmitted command signals for the electric mechanism.
