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 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 system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a first shaft that turns the electrical device on or off when the door is closed. The operating handle is further operable to simultaneously rotate a cam assembly, which in turn rotates a second shaft which displaces an interlock mechanism for engagement or disengagement to a busway structure.

摘要： A wall cavity electrical cupboard system is provided for allowing flush mounting with ready electrical access wiring that is received through holes of the cavity container and can feed along the circumferential channel and into holes of the template openings and can be connected to control means in the electrical mounting module mounted on the support brackets such as fuses, surge protectors, short circuit protection cutoffs etc. Only the front switches or indicators appear through cut outs. The channel and the template openings provide a benefit that the wiring therefore can be selectively moved around and readily connected without needing to line up the holes of the cavity container and the electrical container and with adjustability and safety of placing wiring connection behind the sealing protector plate covering the opening except for what is allowable to show through the cutouts and be mounted on the support brackets.
