An actuator assembly including a first actuator having a first magnetically actuated plunger and a first latching plate, where the first plunger is operable to be magnetically latched to the first latching plate. The actuator assembly further includes a second actuator coupled to and axially aligned with the first actuator. The second actuator includes a second magnetically actuated plunger, a second latching plate, a sleeve positioned within and extending from the second plunger and being rigidly secured to the first plunger, and a tolerance spring wrapped around the sleeve. The second plunger is operable to be magnetically latched to the second latching plate, where latching of the second plunger causes the tolerance spring to compress and provide additional latching force of the first plunger to the first latching plate.

Magnetic latching actuator

A vacuum interrupter including a vacuum bottle, a fixed contact extending through one end of the vacuum bottle and a movable contact positioned within the vacuum bottle relative to the fixed contact so that a gap is defined between the fixed contact and the movable contact when the vacuum interrupter is open and the fixed contact and the movable contact are in contact with each other when the vacuum interrupter is closed. An insulated drive rod is rigidly coupled to the movable contact opposite to the fixed contact and a circular flexible conductor is coupled to the movable contact and flexes when the movable contact is moved by the drive rod. The flexible conductor can be, for example, a laminate structure including a plurality of stacked conductive laminates each having a plurality of spirals separated by gaps or a linear spring trampoline conductor.

Insulated drive vacuum interrupter

A support bracket assembly for supporting a pair of bushing well interrupter devices provided within a transformer enclosure that encloses a transformer. The support bracket assembly includes a mounting bracket assembly rigidly secured to a parking stand on the enclosure and including a plurality of mounting bosses. The support bracket assembly further includes support brackets, a first adjustable link secured to one of the mounting bosses on the mounting assembly and a mounting boss on a support bracket, a second adjustable link secured to another one of the mounting bosses on the mounting assembly and a mounting bosses on a support bracket, and a third adjustable link secured to mounting bosses on two support bracket, where the first, second and third adjustable links form a triangular configuration.

Support bracket for transformer switch utilizing existing transformer connection points

A transformer assembly including a transformer that is part of an underground residential power distribution circuit and that provides fault isolation and restoration. The transformer assembly includes an enclosure enclosing a primary winding and a secondary winding. The transformer assembly also includes first and second switching devices mounted to a panel of the enclosure, where each switching device includes an outer housing, a transformer interface electrically coupled to the primary winding, a connector interface electrically coupled to a first connector and a vacuum interrupter having a fixed contact and a movable contact. The fixed contact is electrically coupled to the connector interface or the transformer interface and the movable terminal is electrically coupled to the other connector interface or the transformer interface.

Transformer for underground radial loop network

An insulating rotary diaphragm for a vacuum interrupter (VI) electrical switch. The insulating diaphragm is designed for use in underground or pad-mounted VI switches where an external lever is rotated by a line worker to manually open the switch. A torsional insulating rod is coupled between a switch actuator and the external lever, and the diaphragm maintains constant contact with the insulating rod and an outer housing when the lever and rod are rotated, thus ensuring adequate isolation between the actuator and the lever. The diaphragm deforms torsionally when the lever and rod are rotated. This configuration allows the actuator to be at medium voltage, eliminates the need for a translational insulating rod between the medium voltage switch components and the lever, and thereby reduces the overall length of the VI switch.

Rotary diaphragm in vacuum interrupter switch

A switching device that is part of a transformer in an underground residential power distribution circuit and provides fault isolation and restoration. The switching device includes a transformer interface for coupling the device to the transformer and a connector interface for coupling the device to a connector. The device also includes a vacuum interrupter having a fixed terminal and a movable terminal, where the fixed terminal is electrically coupled to the connector interface and the movable terminal is electrically coupled to the transformer interface. A control rod is coupled to the movable terminal, an actuator assembly is coupled to the control rod and is operable to move the control rod to open and close the vacuum interrupter. A capacitor is electrically coupled to the fixed terminal, and provides an interface for power line communications signals, voltage sensing, help determine power flow direction and help determine the distance to a fault.

Loop restoration switching device

A switch assembly including a switch and a high impedance element used for energy harvesting purposes that are connected to a power line at one end and assembly electronics at an opposite end, where in one non-limiting embodiment the switch assembly has particular application for use in connection with a vacuum interrupter. The high impedance element has higher impedance than the switch so that current flows through the switch from the power line when the switch is closed and through the high impedance element from the power line when the switch is open, where power from the high impedance element can power a switch closing device, such as a solenoid actuator. The high impedance element can be a resistive element, a capacitive element or a combination of a resistive and capacitive element.
