摘要： An operating mechanism for a circuit breaker is provided. The operating mechanism includes a holder assembly being positioned to receive a portion of an operating handle of the circuit breaker. The holder assembly is capable of movement between a first position and a second position wherein the first position corresponds to a closed position of the circuit breaker and the second position corresponds to an open position of the circuit breaker. The operating mechanism further includes a drive plate being movably mounted to a support structure of the operating mechanism. The drive plate is coupled to the holder assembly. The operating mechanism also includes an energy storage mechanism for assuming a plurality of states, each state having a prescribed amount of energy stored in the energy storage mechanism. When the energy stored in the energy storage mechanism is released it provides an urging force to the drive plate causing the holder assembly to travel in the range defined by the first position to the second position.

摘要： A motor operator for a circuit breaker is disclosed. The motor operator includes a motor drive assembly connected to a mechanical linkage system for driving an energy storage mechanism from a first state of a plurality of states to a second state of a plurality of states. The motor operator also includes an energy release mechanism coupled to the mechanical linkage system for releasing the energy stored in the energy storage mechanism. The mechanical linkage system includes a recharging cam being driven by the motor drive assembly. The recharging cam rotates a drive plate rotatably mounted to the system. A linear carriage is coupled to the drive plate and the linear carriage manipulates an operating handle of a circuit breaker. The recharging cam is disengaged from the drive plate when the energy storage mechanism is compressed into an energy storage state and the drive plate is latched into a position corresponding to the energy stored state. The drive plate is released from its latching position by the energy release mechanism and the stored energy of the energy storage mechanism is released to manipulate the handle of the circuit breaker. The recharging cam is reconnected after the energy of the energy storage mechanism has been released.

摘要： Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.

摘要： Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided.

摘要： A spring powered charging mechanism is operatively coupled with a spring powered, circuit breaker contact operating mechanism such that charging of the operating mechanism springs is powered exclusively by the charging mechanism springs as they discharge. The charging mechanism includes a prop controlled by the condition of the operating mechanism to releaseably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releaseably sustain the breaker contacts open against the urgence of fully charged operating mechanism springs. Consequently, the circuit breaker is capable of executing multiple contact opening and closing operations without recharging.

摘要： A normally manually operable electric switch is provided with stored energy mechanism which can be remotely controlled to open the switch without interfering with the direct manual operation to open or close the switch. The stored energy mechanism consists of a threaded rod portion and releasable screw-threaded means engaging said rod portion and allowing a spring to be compressed; upon release of the releasable screw-threaded means, the spring discharges. The stored energy mechanism is manually operable to render it potentially operable to open the switch automatically by remote control and provision is made to render said mechanism inoperable when said remote control is not desired.

摘要： A quick-set clevis joint for a three-phase electric disconnect switch linkage includes a clevis housing having a spring chamber axially aligned and disposed around a linkage pipe extending through the clevis housing. A spring positioned within the spring chamber provides play in the linkage. First and second thrust disks compress the spring in a first axial direction with the first thrust disk pushed against a first spring chamber end wall when the linkage pipe moves in the first axial direction while the clevis housing is blocked from moving in the first axial direction. In addition. the first and second thrust disks compress the spring in the second axial direction with the second thrust disk pushed against the second spring chamber end wall when the linkage pipe moves in the second axial direction while the clevis housing is blocked from moving in the second axial direction.
