ABSTRACT:
An auto-recloser circuit-breaker has three vacuum interrupters driven from a single bistable magnetic actuator which is powered by a first lithium sulphur dioxide battery under control of an electronic protection relay which is powered by a second lithium sulphur dioxide battery. The drive mechanism, actuator and relay are designed to minimize current consumed by the batteries so that the recloser may be self-powered for its full life by these batteries independent of the power line in which it is connected.
