Abstract: A modular and scalable AC/DC substation transforms AC voltage to DC voltage for driving a high-voltage and high-current load, such as a heavy work machine. Sized to fit within a standard high-cube ISO shipping container, the substation includes a main transformer attached at a center of a rectangular base with a pair of controlled rectifiers positioned on the base downstream from the main transformer, aligned parallel to a lateral axis of the base, and substantially symmetrical to a longitudinal axis of the base. The arrangement of these components on the base, together with lowpass filters and switchgear, achieves high power density for the substation, provides balanced mass for stability during shipment and placement, and helps protect personnel from accidental electrical arcing.

Abstract: A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. A head-end interface of the conductor rod proximate the work machine includes metallic rings spaced apart and extending circumferentially around the head-end interface. Bores pass longitudinally through the head-end interface and into cavities within the conductor rod between the concentric metal tubes. The metallic rings enable the delivery of electrical power radially from the conductor rod for powering the work machine, while the bores enable the delivery of pneumatic power longitudinally into the conductor rod for powering axial movement of the conductor rod.

Abstract: The present disclosure provides a concentric conductor for conducting electrical power from a source to a receiving system or load. The concentric conductor includes one or more conducting tubes interior to an outer tube, extending concentrically around a central axis. The conducting tubes are affixed a head-end interface and a connector assembly at either end of the concentric conductors.

Abstract: A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. A connection assembly includes lugs branching orthogonally from respective ones of the concentric metal tubes to an exterior of the conductor rod. The lugs include ball-and-socket joints configured to enable semi-spherical movement of the lugs at the exterior with respect to the joints. When attached to the contactor via conductive arms, the connection assembly provides multiple degrees of freedom for the conductor rod relative to the contactor and avoids detachment of the contactor from the power rail.

Abstract: A three-rail power supply system includes a power supply having positive, negative, and neutral terminals, a rail system having a power supply end and a termination end, and an asymmetric resistor network. The rail system includes a positive rail, a negative rail, and a ground rail coupled to the positive terminal, the negative terminal, and the neutral terminal, respectively. The negative rail is disposed parallel to the positive rail. The ground rail is disposed in parallel to, and between, the positive rail and the negative rail, and is electrically grounded at a plurality of intervals between the power supply end and termination end. The asymmetric resistor network includes two pairs of resistors asymmetrically coupled to the rail system at the power supply end and termination end, and is configured to limit a fault current through a faulty connection in response the positive, negative, and/or ground rails experiencing the faulty connection.

Abstract: A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving multiple poles of electrical power from a contactor sliding on a power rail. A terminal assembly includes conductive extensions from the respective metal tubes that are arranged concentrically and rotatably around an axis orthogonal with the conductor rod, rotatable metal pins positioned transversely to the axis, and conductive arms connected through hinge joints to respective ones of the rotatable metal pins. When the conductive arms are connected to rotatable and hinged joints at the contactor, the terminal assembly provides multiple degrees of freedom for the conductor rod relative to the contactor and avoids detachment of the contactor from the power rail.

Abstract: A work machine powered electrically by a conductor rod includes a pneumatic control system for moving the conductor rod axially to contact power rails along a haul route. The conductor rod has a central passageway pneumatically coupling a head to a tip. A barrel extending from the head and an arm extending from the tip have concentric tubular conductors radially offset from each other and slidably mated together. Arrangements of pneumatic control valves provide pressurized air to selected cavities formed at ends or sides of the tubular conductors, causing axial forces that are balanced to effect retraction and extension of the arm within the barrel. In an open-loop mode, the pneumatic control system enables attachment of the arm to the power rails. In a closed-loop mode, mechanical feedback of relative position between the arm and power rails leads to axial adjustment pneumatically so that contact with electrical power is maintained despite lateral movements caused by steering or road conditions.

Abstract: A work machine powered electrically by a conductor rod contacting power rails along a haul route. The conductor rod has a central passageway coupling a head to a tip. A barrel extending from the head and an arm extending from the tip have concentric tubular conductors radially offset from each other and slidably mated together. The concentric tubular connectors maintain physical and electrical contact as the conductor rod extends and contracts so that contact with electrical power is maintained despite lateral movements caused by steering or road conditions.

Abstract: A power rail connector for an electric power system in an electric machine includes a linkage having a lower link and an upper link, and a rail contactor coupled to the lower link and including electrical contacts positioned to electrically connect to a power rail. The linkage includes a fold joint, a lift joint, and a pivot, and is adjustable from an extended, current-collecting configuration to a collapsed configuration via rotation of the lower link relative to the upper link and rotation of the upper link relative to the pivot. Related machinery and methodology is also disclosed.
