摘要： A female interrupting contact for a current-interrupting unit includes a smoothly contoured, apertured pressure ring which is held in a groove formed in the wall of a bore through a contact body. A flat spring in the groove maintains the ring to one side of the bore so that the aperture is normally misaligned with the path of a male contact through the bore. When the male contact enters the aperture, it moves the ring against the action of the flat spring to align the aperture with its path. This alignment effects intimate sliding engagement between the male contact and both the ring and the wall of the bore, one or both of the latter of which are conductive so that a reliable, metal-to-metal, first electrical path through the contacts and the interrupting unit is established. The bore is elongated between the pressure ring and an end thereof from which the male contact exits, following which an arc is established between the contacts. This elongation is at least as long as the length of the male contact, so that after the intimate engagement ceases, a second electrical path is established via small arcs or arclets which form between the male contact and the wall of the bore. The length of time the second path exists may be selected so that when the unit interrupts the arc a switch or the like, with which the unit is used, is sufficiently far open to prevent an arc from forming therein.

摘要： A circuit testing closer is capable of closing a power distribution circuit and interrupting the resulting current at the next current zero. Upon detecting a fault, the circuit testing closer is operable to open contacts to isolate the fault. Next, the circuit testing closer tests the faulted line to determine whether the fault has cleared. The circuit testing closer may employ one or more dynamic thresholds to determine the existence of a fault.

摘要： A control system and method of controlling an uninterruptible power supply (UPS) system prevents a load anomaly, such as transformer DC offset, resulting from a supply disruption, such as a voltage sag, by modifying the UPS supplied power curve. The UPS supplied power curve maintains a predetermined power for a predetermined duration to cause the UPS supplied power curve to depart from normal supply curve post sag detection. Following the predetermined duration, the UPS supplied power curve is conformed to the normal power supply curve until restoration of the source power supply or engagement of a secondary power source.

摘要： A circuit testing closer may include a fault isolating switching device coupled between a supply side and a load side of a power distribution system and a current pulse generator coupled in parallel to the switch to generate a current pulse within the power distribution system subsequent to a fault isolation for testing the power distribution system. The current pulse generator may include an electromechanical actuator, an electromagnetic actuator or a solid state switching device. The circuit testing closer may be a purpose-built combination device, or the fault isolating switching device and the current pulse generator may be separately coupled and commonly controlled devices. The fault isolating switching device may have continuous current rating greater than a continuous current rating of the pulse generating device.

摘要： A pre-insertion inductor arrangement is provided for a circuit interrupting device or high voltage switch to reduce audible and electrical noise and to limit transient inrush current and/or voltages upon closing of the circuit by the circuit interrupting device or high voltage switch. The arrangement provides the insertion of the inductor for a plurality of cycles of the source frequency and thus does not require precise timing. The pre-insertion inductor does not require the use of a stack of resistor blocks or cakes of the prior art. Further, since the pre-insertion inductor has relatively low losses, the energy dissipation requirements of the pre-insertion inductor are significantly less than for pre-insertion resistors. Additionally, since the pre-insertion inductor is not continuously in the circuit, there is no requirement to carry continuous load or fault current or to accomodate losses on a continuous basis. Thus, an effective inductance for the pre-insertion inductor can be achieved in a desirable configuration having compact dimensions. In a specific embodiment, the pre-insertion inductor arrangement inserts the inductance between a switch blade and a switch contact during the closing movement of the switch blade. A conducting arm arrangement extends radially from the switch blade and upon movement of the switch blade the conducting arm arrangement is moved into juxtaposition with a conductor connected to the pre-insertion inductor assembly. The pre-insertion inductor assembly is mounted on and to one side of the stationary switch contact. The pre-insertion inductor assembly is connected in series with the switch blade and limits the transient inrush current and/or voltages incident to the closing of the switch.
摘要翻译： 为电路中断装置或高压开关提供预插入电感器布置，以减少电声和电噪声，并且通过电路中断装置或高压开关闭合电路来限制瞬时浪涌电流和/或电压。 该布置提供了电感器在源频率的多个周期中的插入，因此不需要精确的定时。 预插入电感器不需要使用现有技术的电阻器块或蛋糕的堆叠。 此外，由于预插入电感器具有相对较低的损耗，因此预插入电感器的能量耗散要求明显小于预插入电阻器的能量耗散要求。 此外，由于预插入电感器不是连续地在电路中，所以不需要承载连续负载或故障电流或连续地承受损耗。 因此，可以在具有紧凑尺寸的期望配置中实现用于预插入电感器的有效电感。 在具体实施例中，预插入电感器装置在开关叶片的闭合运动期间将电感插入开关叶片和开关触点之间。 导电臂装置从开关叶片径向延伸，并且在开关叶片移动时，导电臂装置与连接到预插入电感器组件的导体并置移动并置。 预插入电感器组件安装在固定开关触点的一侧上。 预插入电感器组件与开关叶片串联连接，并限制入射到开关闭合的瞬态浪涌电流和/或电压。
