摘要： A circuit breaker, and method of constructing same, in which a levering-in mechanism may be added after the circuit breaker has been assembled. The circuit breaker includes a chassis having first and second side plates which define upwardly open slots, which enable the levering-in mechanism to be "dropped in" to the correct position of an assembled circuit breaker, with bottom portions of the slots functioning as half bearings. First and second retainer plates with downwardly open slots are respectively attached to the first and second side plates, to complete the half bearings and hold the levering-in assembly. The levering-in mechanism includes a threaded shaft having a traveling nut, with a bushing on the shaft being held radially, but not axially, by a bracket member, with the bushing also functioning as a non-stress stop for the traveling nut. New interlock arrangements are also associated with the levering-in mechanism, including interlocks which: (1) prevent access to the levering-in mechanism, (2) place the circuit breaker in a trip-free condition, and (3) discharge closing spring, in response to predetermined conditions.
摘要翻译：一种断路器及其构造方法，其中在组装断路器之后可以添加杠杆引入机构。断路器包括具有第一和第二侧板的底盘，其限定向上开口的槽，这使得杠杆进入机构能够“落入”到组装的断路器的正确位置，其中槽的底部部分用作一半轴承。具有向下开口的槽的第一和第二保持板分别附接到第一和第二侧板，以完成半轴承并保持杠杆组合。杠杆引入机构包括具有行进螺母的螺纹轴，轴上的衬套通过支架构件径向地保持而不是轴向地保持，衬套还用作行进螺母的非应力停止。新的联锁装置还与杠杆机构相关联，包括互锁：（1）防止进入杠杆机构，（2）将断路器放置在无跳闸状态，（3）放电闭合弹簧，响应于预定条件。

摘要： Operation of a medium voltage spring powered circuit breaker is analyzed by applying a recording medium in the form of an adhesive backed tape to a selected driven part of the operating mechanism. A marking instrument is held in contact with the recording medium at a fixed point by a fixture in the form of a template secured to the circuit breaker frame. When the charged closing springs of the operating mechanism are released, the marking instrument produces a trace on the recording medium which is then analyzed to provide a quantitative evaluation of switch operation, including overtravel of the selected driven part.

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： Protection is provided for servicing a distribution bus by grounding the line side of a circuit breaker through which the distribution bus is fed and then closing the circuit breaker. The trip unit of the circuit breaker includes logic, in addition to the normal protection logic, which opens the circuit breaker main contacts without delay if current is detected upon closing of the grounded circuit breaker. However, if the grounded circuit breaker has been closed for a selected period of time and then current is detected, the distribution bus is kept at zero potential by not operating the breaker. A breaker auxiliary switch with a mechanical delay provides the indication of the selected time interval after closing the circuit breaker.

摘要： A circuit breaker contact operating structure characterized by a circuit breaker operating mechanism having separable contacts of which one is mounted on a contact carrying arm. The arm being mounted on a one leg of a U-shaped flexible conductor. A guide link is pivotally mounted and connected to the arm to maintain the contacts in alignment during their separation. The operating mechanism having a latch for latching the arm in the closed-contact position of the arm and having a trip device for unlatching the latch in response to an overcurrent condition. The mechanism link is so placed on the contact arm structure as to effect a blow-on force on the contact structure during the duration of high overcurrent. At a preset current level, the mechanism link is prevented from applying the balancing force to the contact structure, thus allowing the blow-off forces due to the current in the contact structure to separate the contacts rapidly, and to effect current limitation and subsequent circuit interruption.
摘要翻译：一种断路器触点操作结构，其特征在于具有可分离触点的断路器操作机构，其中一个触点安装在触点承载臂上。臂安装在U形柔性导体的一条腿上。引导连杆可枢转地安装并连接到臂上，以便在分离过程中保持接触对齐。操作机构具有用于将臂锁定在臂的闭合接触位置中的闩锁，并具有用于响应于过电流条件解锁闩锁的跳闸装置。机构连杆被放置在接触臂结构上，以在高过电流持续时间内对接触结构产生吹胀力。在预设的电流水平下，防止机构连杆对接触结构施加平衡力，从而允许由接触结构中的电流引起的吹出力快速分离触点，并实现电流限制和后续电路中断

摘要： An enclosure structure for housing switchgear apparatus (such as circuit breakers) is fabricated from a pair of sheet metal panels that are held in precisely-spaced upstanding relationship by a plurality of metal cross-struts of U-shaped cross-section which mechanically interlock with apertured portions of the panels and are held in such position by triangular-shaped metal gussets which overlap and are bolted to adjacent portions of the cross-struts and panels. The cross-struts are provided with longitudinally protruding tangs at each end that are slip-fitted into and interlock with slot apertures in the panels. The width dimension of the finished enclosure structure is precisely controlled by positioning tabs on the ends of the cross-struts that are offset from the associated tangs and are drawn into abutting relationship with the inner surfaces of the respective panels when the structure is bolted together. Construction and assembly of the enclosure structure is accordingly achieved without the expensive tooling, jigs and welding operations heretofore required to manufacture such structures.
