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： 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： 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.
摘要翻译：提供一种用于具有构造成接合和移动肘节组件的柱塞组件的电开关设备的操作机构闭合组件。柱塞组件包括一个在一个最好是直的路径上行进并接合肘节组件的冲头体。路径可以由延伸穿过压头主体的一个或多个销定义。一个或多个弹簧联接到冲头主体并将冲头主体偏压到肘节组件。弹簧可以方便地围绕销布置。在该构造中，由弹簧产生的力基本上直接施加到肘节组件。肘节组件联接到并且构造成旋转，该极轴进一步联接到并且构造为致动电气开关设备触点。因此，由于由弹簧产生的力不通过一个或多个凸轮传递，与现有技术相比，所需的力以及因此的弹簧尺寸减小。

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. A stop member is employed for engagement with the ratchet wheel to prevent reverse rotation of the ratchet wheel during charging of the close spring. To reduce friction force between the stop member and the ratchet wheel once the close spring is fully charged and it is desired to discharge the spring, the ratchet wheel includes a toothless region formed on the periphery thereof. The ratchet wheel is positioned such that the stop member is in engagement with the toothless region once the close spring is fully charged. Friction between the stop member and the ratchet wheel is reduced by eliminating the need for the stop member to traverse the teeth of the ratchet wheel as discharging of the spring is initiated.
摘要翻译：电气开关装置的操作机构中的大的闭合弹簧由充电机构充电，该充电机构包括安装在凸轮轴上并由棘轮旋转的充电凸轮。使用止动构件与棘轮接合以防止在闭合弹簧充电期间棘轮的反向旋转。为了减少闭合弹簧充满电之后止动构件和棘轮之间的摩擦力，并且期望排出弹簧，棘轮包括形成在其周边上的无齿区域。棘轮被定位成使得止动构件一旦闭合弹簧被充满电就与无齿区域接合。当停止构件和棘轮之间的摩擦开始时，消除了停止构件在棘轮的齿上穿过的需要。

摘要： A linkage for a solenoid actuated circuit breaker operating mechanism is provided. The operating mechanism includes a trip device and a close device. Either the trip device or the close device is coupled to a solenoid, by an ultra-lightweight connection member. The ultra-lightweight connection member is so light as to not create a sufficient force to effect the trip device or the close device even when the circuit breaker is subjected to a shock load.
