摘要： A medium-voltage switchgear system includes a three-phase circuit breaker having first, second and third single-phase vacuum interrupters connected between respective first, second and third single-phase inputs and first, second and third single-phase outputs. Magnetic actuators are connected to first, second and third single-phase vacuum interrupters, which are configured to receive an interrupt signal and in response, actuate the respective vacuum interrupter connected thereto into an open circuit condition. A controller circuit is connected to each of the first, second and third magnetic actuators and generates an interrupt signal in response to a detected single-phase overcurrent or fault on a single-phase circuit and interrupt that single-phase circuit on which the single-phase overcurrent or fault occurred and maintain power on the remaining two single-phase circuits over which a single-phase overcurrent or fault was not detected.

摘要： An electrical enclosure includes a main cabinet and a modular cabinet removably secured to the main cabinet. The main cabinet includes a bus compartment that includes a busbar assembly, and the bus compartment is located between an end wall of the main cabinet and a partition opposite the end wall. The modular cabinet is comprised of interlocking compartment modules. Each compartment module interlocks with an adjacent compartment module. Each compartment module includes first and second side panels. Each side panel includes an alignment member that engages an alignment member of a respective side panel of the adjacent compartment module. Each compartment module also includes a base that extends between the first and second side panels and a terminal wall that joins the first and second side panels. The terminal walls of the interlocking compartment modules engage to form a structural wall of the modular cabinet.

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 low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure and/or one of said compartments with a second compartment. The venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition at first predetermined temperatures and the enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition at second predetermined temperatures. The actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at said first predetermined temperatures reversibly changeable into a second dimension at said second predetermined temperatures, the reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determining the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.

摘要： Disclosed examples include enclosures with segregated or divided cooling paths and improved arc flash resistance. In one example, a TYPE 12, 50 DEGREE C. ambient common bus power conversion enclosure design provides enhanced arc flash protection & segregated cooling for high reliability of imbedded electronics. Example enclosures and systems can be used in association with AC/DC converters for motor drives or motor control centers, and/or for electroplating or painting systems with modular anode control (MAC) systems to implement an anodic DC electroplating for workpieces and other end use applications.
