摘要： A grounding switch device for a metal-clad switchgear is adapted to be inserted into a standard circuit breaker cell allows the bus and line conductors within the switchgear assembly to be grounded for maintenance. A plurality of fixed and selectable test ports are provided to facilitate various electrical tests. The ground switch device is disposed on a frame and contains a ground contact assembly for providing sliding contact between the ground switch device and the ground bus within the circuit breaker cell. The ground contact assembly is in electrical contact with a movable contact. The movable contact is adapted to engage a stationary contact mounted on a mounting plate, attached to the frame by way of an insulator. A selector switch assembly connects the stationary contact to either the upper bus terminals or line terminals in the metal-clad switchgear assembly. The contact portion of the movable contact is U-shaped having two spaced-apart blades. Each blade is adapted to be received in a jaw portion of the stationary contact assembly. The jaw portions of the stationary contact assembly are formed by a pair of U-shaped current loops having inwardly facing protrusions disposed intermediate the bight portion. These protuberances force the contact arm into the jaw when the switch is closed on a live circuit. A combination spring and damper is disposed adjacent the protrusion to provide contact pressure when the ground switch contacts are closed and also to prevent contact bounce which can cause arcing and welding of the assembly.

摘要： A compact power circuit breaker has a molded insulative casing providing the structural support and electrical isolation for the pole mechanisms mounted in cavities in the casing and the operating mechanism mounted to the front of the casing. A grounded barrier between the pole mechanisms and the operating mechanism protects the operator actuating push buttons controlling the operating mechanism and accessible through a molded insulative cover. Preferably, the grounded barrier is sandwiched between a rear section of the molded casing containing the pole cavities and a forward section to which the operating mechanism is secured. The grounded barrier is connected to an electrically conductive pan extending under the molded insulative casing which also houses electrically grounded linkages coupling the operating mechanism to the vacuum interrupters of the pole mechanisms. A vented air gap between the rear section of the molded insulative casing and the grounded barrier minimizes erosion of the molded insulative casing in the event of an arc penetrating the casings to the grounded barrier.

摘要： A stored energy assembly is provided for an electrical switching apparatus, such as a circuit breaker. The stored energy assembly includes a mount removably coupled to the circuit breaker housing. A stored energy mechanism, such as a spring, is coupled to the mount and is movable among charged and discharged positions. An actuating element is cooperable with the gears of a gear assembly in order to move among first and second positions corresponding to the spring being disposed in the charged and discharged positions, respectively. A manual charging mechanism and an automatic charging mechanism are coupled to the gear assembly, and move the gears, in order to move the actuating element and charge the spring. The spring, the actuating element, the gear assembly, and the charging mechanisms are coupled to the mount, thereby forming a sub-assembly. The sub-assembly is removably coupled to the circuit breaker housing.

摘要： A flexible shunt in the form of a flexible member made up of a stack of electrically conductive laminations each of a thickness of no more than about 0.002 inch (0.051 mm) has a moveable end secured by a moveable mount to a moveable contact support of an electric power switch for movement along a linear path. A fixed mount secures the fixed end of the flexible member to a fixed conductor termination spaced laterally from the moveable end along a neutral axis perpendicular to the linear path of the moveable end by an offset distance such that the installed length of the intermediate section between the fixed and moveable ends is less than the free length of the intermediate section. With this arrangement the stroke of the moveable end along the linear path can be up to at least ⅓ and even ½ of the free length of the intermediate section of the flexible member and with very low operating forces.
