US 11,387,066 B2 · Cutout mounted recloser

Abstract

A cutout mountable recloser that remains latched to the cutout until the recloser is selectively mechanically unlatched via at least rotation of a driver by an operator. During installation, including while the recloser is being latched to the cutout, the recloser can be in an open condition. Latching of the recloser to the cutout can include increasing a tension force exerted by the cutout on the recloser by increasing a linear distance between first and second terminals of the recloser. With the opened recloser latched to the cutout, the recloser can be mechanically closed via a release of stored energy from a closing mechanism. The recloser can selectively be mechanically unlatched from the cutout by a subsequent reduction in the linear distance between first and second terminals of the recloser, which can reduce the tension force being exerted by the cutout.

Dependent claims

A cutout mountable recloser comprising:

a first terminal;
a recloser assembly electrically coupled to the first terminal, the recloser assembly comprising a current interrupter, an electromagnetic actuator, and a pushrod;
a latch system coupled to the recloser assembly, the latch system comprising a lower terminal latch plate, the lower terminal latch plate pivotally displaceable between a first, raised position and a second, lowered position;
and
a second terminal coupled to the lower terminal latch plate, the second terminal being pivotally displaceable between a raised position and a lowered position by the pivotable displacement of the lower terminal latch plate between the first, raised position and the second, lowered position,
wherein the second terminal is electrically coupled to the recloser assembly and is separated from the first terminal by a first linear distance when the second terminal is in the raised position, and by a second linear distance when the second terminal is in the lowered position, the first linear distance being smaller than the second linear distance.

A recloser structured for a selectively releasable latching engagement with a cutout, the recloser comprising:

a driver,
a first terminal;
a recloser assembly electrically coupled to the first terminal and coupled to the driver, the recloser assembly comprising a current interrupter, a pushrod, an electromagnetic actuator, and a closing mechanism, the closing mechanism having at least one closer body and at least one mechanical biasing element, the at least one mechanical biasing element releasing a force, when the closing mechanism is discharged from a charged state to a discharged state, that displaces the at least one closer body into a moving engagement with the pushrod, the moving engagement displacing the pushrod to a position that electrically closes the current interrupter;
a latch system coupled to the driver, the latch system having a lower terminal latch plate that is pivotally displaceable in between a first, raised position and a second, lowered position;
and
a second terminal coupled to the lower terminal latch plate and electrically coupled to at least the recloser assembly, the second terminal being pivotally displaceable between a raised position and a lowered position by the pivotable displacement of the lower terminal latch plate between the first, raised position and the second, lowered position.
