摘要： An auxiliary switch operator for a circuit breaker operates auxiliary contacts between open and closed positions. The auxiliary switch operator includes a hub which is biased to follow a pole shaft of the circuit breaker and follow the pole shaft when it rotates in a first direction to close separable contacts of the circuit breaker. A first spring mechanism biases the hub to follow the pole shaft when the pole shaft rotates in the first direction. When the pole shaft rotates in the first direction, an arm of the hub engages a rotatable shaft to drive an operating lever and operate the auxiliary contacts to the closed position. When the pole shaft rotates in the second direction, another arm of the hub recharges the first spring mechanism. A second spring mechanism biases the rotatable shaft and the operating lever toward a position corresponding to the open position of the auxiliary contacts when the pole shaft rotates in the second direction.

摘要： A mechanical interlock device for preventing simultaneous operation of two 3-phase vacuum interrupter-type circuit breakers is provided. The device operates with the floor tripper and the Mechanism Operated Control ("MOC") driver of each vacuum circuit breaker. The device includes a retainer member mounted at the base of each circuit breaker. Each retainer member includes two levers. The first lever is a trip lever which engages the floor tripper of the associated circuit breaker. The second lever is driven by the MOC driver of the associated circuit breakers. The two levers are preferably mounted on a common pivot bar located at one end the retainer member. Cabling is provided between the trip lever on the first circuit breaker and the MOC driver lever on the second circuit breaker. Similarly, a cable is provided between the MOC driver lever of the first circuit breaker and the trip lever of the second circuit breaker. When either circuit breaker is in normal operation, its MOC driver is in a downward position. This forces the MOC driver lever downward which in turn rotates the trip lever in the opposite breaker upwards. The trip lever thereby acts to engage the floor tripper of the opposite circuit breaker which in turn forces the circuit breaker open and prevents it from operating while the other circuit breaker is on.
摘要翻译：提供一种用于防止两个三相真空断路器型断路器同时工作的机械互锁装置。该设备与每个真空断路器的地板跳闸器和机构操作控制（“MOC”）驱动器一起工作。该装置包括安装在每个断路器的基座处的保持器构件。每个保持构件包括两个杠杆。第一个杠杆是与相关断路器的地板跳闸相接合的跳闸杆。第二个杠杆由相关断路器的MOC驱动器驱动。两个杠杆优选地安装在位于保持构件一端的公共枢轴上。在第一断路器上的跳闸杆和第二断路器上的MOC驱动器杆之间提供布线。类似地，电缆设置在第一断路器的MOC驱动器杆和第二断路器的跳闸杆之间。当断路器正常运行时，其MOC驱动器处于向下位置。这迫使MOC驾驶员杠杆向下，这反过来又使相对的断路器中的跳闸杆向上旋转。因此，脱扣杠杆用于接合相对断路器的地板跳闸器，这反过来又迫使断路器断开，并防止其断路器接通。

摘要： A circuit breaker having a contact movable between open and closed positions, includes a closing spring assembly having a closing spring and first and second brackets. The closing spring assembly is chargeable when in a reset position in which the first bracket is hooked by a first hook. The closing spring is charged, manually or electrically, with support of the second bracket being transferred to a second hook. The closing spring is discharged to close the circuit breaker, with the closing spring assembly moving from the reset position to a discharged position in the process. The closing spring assembly is then moved as an integral unit, back to the reset position, with the closing spring again being charged, enabling the circuit breaker to immediately reclose in the event of a trip due to a transient condition. An improved breaker operating mechanism and power operated charging mechanism, are also disclosed.

摘要： A drawout switchgear apparatus is characterized by a cell having a front opening through which a circuit breaker is movable on tracks into and out of the cell for engagement and disengagement with electrical terminals within the cell. A cell frame includes formed columns at outside corners members, cross-strut members, and formed horizontal members which members are of similar cross-section of a substantially U-shape with U-legs and a bight and with a laterally extending flange. Each member converges to form junction corners where they are fastened together. A track extension and interlock cooperate to facilitate removal and retention of the unit into and out of the cell.
