    摘要： The present invention discloses a busbar chamber arc-striking assembly, which includes a main frame forming a space configured to accommodate a busbar chamber sleeve, wherein the main frame includes a back plate, and the back plate is arranged on a side of the busbar chamber sleeve opposite to the busbar; and a first arc-striking plate which is parallel to and spaced apart from the back plate of the main frame, wherein the first arc-striking plate is installed to extend between adjacent busbar chamber sleeves. The busbar chamber arc-striking assembly according to the present invention can quickly strike the arc at the initial stage of arc generation, cut off the arc, reduce the arc energy, and ignite the arc itself until the arc is extinguished.

    摘要： A switchgear cabinet (100) includes an equipment compartment (102), a bus compartment (104) and a cable compartment (106). The cabinet can employ a sensor(s) (190) to monitor conditions, such as arcing, in the bus or cable compartment. The cabinet also includes a retractable sensor system (150), which has a rack (160) and a slider (170). The rack is mounted in the cabinet, and the slider is configured to retain the sensor. The slider is movably engaged to the rack. The slider can slide in one direction toward a back of the bus or cable compartment to a racked-in position in which the sensor is located to sense arcing in the bus or cable compartment. The slider can slide in an opposite direction toward a front of the equipment compartment to a racked-out position in which the sensor is drawn into the equipment compartment.

    摘要： An electrical enclosure is configured for passive self-extinguishing arc protection and cooler operation of enclosed equipment. The enclosure has a channeled ventilation system with arc channels in fluid communication with exhaust channels. The arc channels around each phase of the enclosed conductors are of sufficient length to help attenuate an arc. The exhaust channels are placed in communication with the arc channels. The geometry and materials of the arc channels and exhaust channels cause the energy balance of the enclosure to favor passive arc interruption. Ventilation channels may be in fluid communication with the arc channels and the exhaust channels to provide cooling airflows over enclosed power conductors during normal non-arcing operation.
