    摘要： EACH SECTION OR CELL OF A THREE-PHASE METAL-ENCLOSED SWITCHGEAR UNIT, WHICH MAY INCLUDE A PLURALITY OF CELLS, HAS A BREAKER COMPARTMENT AT THE FRONT, A CABLE COMPARTMENT AT THE REAR, AND A BUS OR CONDUCTOR COMPARTMENT BETWEEN THE CABLE COMPARTMENT AND THE BREAKER COMPARTMENT. THE BUS COMPARTMENT CONTAINS HORIZONTALLY EXTENDING MAIN PHASE BUS BARS AND VERTICALLY EXTENDING RISER CONDUCTORS FOR CONNECTING THE BUS BARS TO THE CIRCUIT BREAKERS, OR OTHER CIRCUIT CONTROLLING DEVICES, BY MEANS OF STAB CONDUCTORS AT DIFFERENT EVELATION IN THE BREAKER COMPARTMENT. FEEDER CONDUCTORS EXTEND HORIZONTALLY FROM THE CIRCUIT BREAKERS THROUGH THE BUS COMPARTMENT AND TERMINATE IN THE CABLE COMPARTMENT.

    摘要： An arc-chute of the space-plate type is provide for an air-break circuit breaker in which a molded insulating casing is provided with grooves for supporting the spaced magnetizable conducting plates. The casing has an enlarged lower opening communicating with a laterally disposed restricted opening. Additionally, the insulating casing has flange, or shelf means integrally formed therewith to prevent downward movement or blasting of the arcing gases, which are heated during the arcing interrupting operation. Above the space metallic magnetizable plates are provided a plurality of spaced expansion chambers, which are partitioned from each other by vertically extending solid insulating plate portions interspersed lengthwise of the arc-chute along the upper portion thereof.
