    摘要： Disclosed herein is a circuit breaker having a closing resistor, which is capable of preventing impact caused when the circuit breaker is opened and closed from being transferred to peripheral structures. The circuit breaker having a closing resistor includes a fixed part having a fixed contact, a movable part having a movable contact, a closing resistor unit connected to the fixed part and having a closing resistor unit contact, a closing resistor movable part connected to the movable part and having a closing resistor movable contact, and a support structure slidably coupled to the closing resistor unit in a direction parallel to a movement direction of the closing resistor movable part, thereby enabling impact and vibration applied to the closing resistor unit to be absorbed by the support structure.

    摘要： An arc extinguishing contact assembly for a circuit breaker assembly is provided. The arc extinguishing contact assembly includes a fixed contact assembly, a movable contact assembly and an arc extinguishing assembly. The fixed contact assembly includes a fixed arc contact assembly, a fixed main contact assembly, and a number of movable, intermediate arc contact assemblies. The movable contact assembly includes a movable arc contact assembly and a movable main contact assembly. The arc extinguishing assembly is structured to extinguish an arc generated as the movable contact assembly moves between an open, first position and a closed, second position.

    摘要： Extending between a fixed tulip contact (1) and a slide tulip (4) is an arcing chamber (5) which is occupied in the closed position by a movable contact pin (3) which fills up both an exhaust (9) surrounded by the slide tulip (4) and a blowout opening (7) which is surrounded by the tulip contact (1) and connects the arcing chamber (5) to a pressure chamber (6). The arcing chamber (5) is surrounded by an annular heating volume (13) open toward the same. Arranged in the pressure chamber (6) is a charge (10) of explosive which is for the most part converted within approximately 10-30 ms after ignition to extinguishing gas, preferably predominantly nitrogen, the gas pressure moving the contact pin (3) toward the open position. After clearance of the blowout opening (7) and the exhaust (9), the arc drawn between the contact pin (3) and tulip contact (1) is blown out, something which is supported by the pressure buildup, to which the arc contributes, in the heating volume (13). The pressure chamber with the charge can also surround the arcing chamber in an annular fashion. In this case, it is also possible to support the opening movement by the explosion pressure, for example, via pistons.

    摘要： A gas-blast type of circuit interrupter is provided having an arcing chamber of insulating material with rows of lateral venting slots, serving as splitters. A cluster of stationary contact fingers within the arcing chamber make separating engagement with a tubular movable contact. A stationary hollow insulating arc plug is provided interiorly of the arcing chamber, within which gas is forced to flow. The arcing plug has lateral inlet slots provided therein, which emit arcing gas under pressure into the interior of the arcing chamber and laterally outwardly across the arc, and radially outwardly through the lateral slots provided in the stationary insulating arcing chamber. The arc is moved by the radial outward blast to be forced against the arcing splitters provided by the sidewalls of the stationary insulating arcing chamber. As an alternate arrangement, a side lateral dump is provided adjacent an elongated arcing contact finger, at which the arc is constantly drawn. This prevents the accumulation of stagnant ionized gases and arc products, which may otherwise accumulate in the pocket surrounding the annular stationary contact finger assembly.
