摘要： An operating mechanism closing assembly for an electrical switching apparatus having a ram assembly structured to engage and move a toggle assembly is provided. The ram assembly includes a ram body that travels over a, preferably, straight path and engages the toggle assembly. The path may be defined by one or more pins extending through the ram body. One or more springs are coupled to the ram body and bias the ram body toward the toggle assembly. The springs may be conveniently disposed about the pins. In this configuration, the force created by the springs is, essentially, applied directly to the toggle assembly. The toggle assembly is coupled to, and structured to rotate, a pole shaft that is further coupled to, and structured to actuate, the electrical switching apparatus contacts. Accordingly, because the force created by the springs is not transferred via one or more cams, the required force, and therefore the size of the springs, is reduced compared to the prior art.

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： An operating arrangement is provided for a mechanism or the like, e.g. an operating mechanism for a circuit interrupter for electrical power transmission and distribution systems where the operating mechanism operates on stored energy and requires a recharging operation after the stored energy is utilized to operate the circuit interrupter. The operating arrangement includes an operating member and a cooperating arrangement carried by the operating mechanism for retaining the operating member during a multi-turn charging operation. Initial operation of the operating member for one or more turns causes the operating member to be retained before any charging operation takes place. Subsequent operation of the operating member results in the charging of the operating mechanism. The operating member is then returned to an initial engagement position whereupon the operating member is released for removal from the operating mechanism. In a specific embodiment, an interlock function is also provided for the operating member, such that a key must be obtained from an associated device and inserted into the operating member before a recharging operation may begin for the operating mechanism. The key is inserted into the operating member and help captive therein before the operating member may be utilized to recharge the operating mechanism. In a specific implementation, the key is released from the associated device only when the associated device is locked in a particular operative state, e.g. a disconnect switch is locked open which releases the key for use in the operating member. Thus, while the key is held captive in the operating member during recharging operation, the disconnect switch cannot be operated.

摘要： The large close spring in the operating mechanism of electrical switching apparatus is charged by a charging mechanism which includes a charging cam mounted on a cam shaft and rotated by a ratchet wheel. An elongated handle is mounted for rotation about a pivot axis offset laterally from the cam shaft. A drive link which successively engages the teeth on the ratchet wheel is pivotally connected to the handle at a point closer to the handle pivot axis than the radius of the ratchet wheel to increase the mechanical advantage of the handle. A common spring biases the drive link and a stop dog against the ratchet wheel. A turned pin on the drive link is used to engage the ratchet teeth which have an arcuate profile including a radius at the root configured to be engaged by the turned pin. A similar drive link with a turned pin to engage the ratchet teeth is reciprocated by an electric motor. A handle decoupling cam and a motor decoupling cam lift the respective drive links out of engagement with the ratchet wheel when the close spring becomes fully charged. A lifting pin and/or a lateral projection on the handle drive link disengage the handle from the ratchet wheel as the handle is stowed.

摘要： An operation mechanism of a circuit breaker which is highly reliable and inexpensive and in which an intermittent meshing of toothed wheels and resultant noise do not occur. The operation mechanism includes a gear wheel for driving a cam shaft to store mechanical energy into a breaking spring, a pinion meshed with the gear wheel and a clutch driving element provided on the same axis as the pinion and constituting a clutch with the pinion. An operational driving electric motor is provided to drive the clutch driving element. Coupling between the pinion and the clutch driving element is disconnected by means of a cam mechanism composed of an end cam provided on an end face of the gear wheel and the clutch driving element, in the vicinity of the stationary positions of the cam and the gear wheel in the force storing state of a closing spring.

摘要： A mechanism for accumulating and storing mechanical energy, wherein the energy is used to close the primary contacts of a circuit breaker. The energy can be input to the mechanism manually or by means of a motor. The mechanism includes a series of linkages which function to utilize the energy to close the primary contacts. These linkages also function to maintain the closing force upon the primary contacts, while also functioning to allow rapid contact opening when desired.

摘要： In a switch operating mechanism in which the elastic force of a spring energized is transmitted through a link mechanism to achieve a switch opening or closing operation, one end of a first torsion bar is fixedly secured to a rotatable member while the other end is fixedly secured to a stationary part of the mechanism, and one end of a second torsion bard is fixedly secured to the rotatable member in such a maner that the one end is diametrically opposite to the one end of the first torsion bar while the other end is rotatably supported by the stationary part and coupled to the link mechanism.
