摘要： Systems and methods for configuring, with an external device, a power distribution box having priority disconnects. The power distribution box includes a housing portion and a base portion elevating the housing portion. The power distribution box receives power from an external power source and distributes the power to a plurality of alternating current (AC) output receptacles. The power distribution box further includes an antenna and a power disconnect controller coupled to the antenna to communicate with and be configured by an external device, such as a smart phone, tablet, or laptop computer. Using the external device, a user can configure the priority level and mode of the AC output receptacles. In the case of high current, the power distribution box will disconnect receptacles in accordance with the priority level and mode configuration provided by the external device.

摘要： A split door submersible housing for an electrical distribution system includes a cabinet body defining an interior region configured to accept a component of the electrical distribution system, and a first door and a second door positioned side by side to cover an open front portion of the cabinet body. The cabinet body includes at least one opening configured to accept an electrode sealed with and electrically isolated from the cabinet body and extending through the cabinet body to establish electrical connection between a corresponding terminal of the component and an electrical distribution network. A gasket system is provided, which comprises a first gasket configured to fit on the first door and a second gasket configured to fit on the second door. The gasket system seals the first door and the second door against each other and against a corresponding surface on the cabinet body, when the first and second doors are closed and locked, so that the housing is water tight.

摘要： A door support system is provided for an enclosure of an electrical distribution system. The door support system includes a rail fixedly secured to a door panel of the enclosure. The rail includes at least one notch. The door support system also includes a support member mounted to a frame of the enclosure. The support member is slidably mounted to the rail such that the support member slides along a length of the rail between an extended position and a retracted position. The extended position of the support member supports the door panel in an open position. The support member is in the retracted position when the door panel is in a closed position. The support member includes a detent configured to be received into the notch of the rail to releasably lock the support member in the extended position along the length of the rail.

摘要： Methods and systems for HVDC and/or MVDC power transmission and/or distribution, using circuit breakers where a series-connected stack of fully-bidirectional bipolar junction transistors is the initial interrupter in the current path. Preferably these transistors are operated with two pre-turnoff phases, to deplete minority carrier population and thus provide a faster transition to complete turnoff.

摘要： A subsea power distribution device and system. The subsea power distribution device includes a first watertight housing accommodating at least one transformer having a primary winding and at least one secondary winding, input terminals electrically connected to the primary winding and arranged to be connected to a remote power supply, an output terminal electrically connected to the at least one secondary winding, and switches located within the first watertight housing and arranged to open and close the connections between each secondary winding and a corresponding output terminal. Each output terminal is further connected to an overcurrent breaking device which is further arranged to be connected to a subsea power consuming device. The overcurrent breaking device is arranged in a second watertight housing separate from the first watertight housing and is filled with insulating liquid.

摘要： A power distribution box apparatus and method for implementing a priority disconnect scheme and a network communication bridge at a worksite, where the power distribution box distributes temporary power. The power distribution box includes a housing portion and a base portion elevating the housing portion off of the ground or another surface. The power distribution box includes a communication module having a network connecting module operable to connect to an external communication network (e.g., the Internet), and a wireless network module operable to wirelessly communicate with an external device (e.g., a smart phone) to, thereby, connect the external device to the external communication network. The power distribution box may also include a priority disconnect module to selectively disconnect AC output receptacles in response to over-current situations based on a priority level associated with each receptacle.

摘要： An electric power distributor comprises a distributor housing, conversion parts which convert electric current from outside of the distributor housing to low-voltage alternating current, a transformer which transforms the low-voltage alternating current from the conversion parts to high-voltage alternating current and a power transmission part which transmits the high-voltage alternating current from the transformer to the outward distributor housing. The distributor housing comprises two conversion parts—and the power transmission part—inside. The transformer is attached to the distributor housing from outside. The transformer and the power transmission part are placed along a predetermined direction in this order, the two conversion parts are placed along a direction approximately orthogonal to the predetermined direction at an opposite side to the transformer with regards to the power transmission part.

摘要： A power supply module for intelligent electronic apparatuses and capable of transforming the energy of the LV network and of a battery into energy that can be used by said apparatuses is produced to serve as support for said apparatuses. In particular, for a use in a telecontrol equipment item, the casing of the power supply module is flat, can be installed on wall-mounted DIN rails, and includes, on its front face, a DIN rail for fixing the apparatuses that it powers, that is to say other functional modules of the equipment. The casing also includes an apron for the connections. Preferably, the power supply is produced by series connection, and the power supply module includes a port dedicated to external communication via a module of the equipment.
