摘要： A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

摘要： A passive arc control system for a motor control center 60 includes an arc attenuating box having sides separating adjacent vertical bus bar phases 54, providing a physical barrier to arc flash energy. The box is open at its top and bottom forming a chimney 55. A shutter assembly for each box includes an insulator cap 62 on a free end of the bus bar and an independently moveable, box-shaped shutter 64 that slides along the bus bar away from the insulator cap, when a device is connected to the bus bar. The shutter has an opening 65 through which the bus bar passes when the device is connected to the bus bar and an opening 55′ aligned with the box's chimney. The arc control system provides a high degree of arc protection for personnel working around open motor control centers and is highly modular and easy to construct.

摘要： The present invention relates to a door interlock device for a vacuum circuit breaker, and more particularly, a door interlock device for a vacuum circuit breaker, which is operable in cooperation with an operation of a cradle shutter. A door interlock device for a vacuum circuit breaker according to one embodiment disclosed herein includes a pressing unit that is provided on one end portion of a shutter lever driving a terminal shutter of a cradle, a driving force transfer unit that is rotatably or slidably installed on a cradle side frame, the driving force transfer unit performing a rotary motion or a sliding motion by a force applied from the pressing unit, and a sliding member that is configured to lock or unlock a door lock plate in response to a driving force transferred from the driving force transfer unit.
