摘要： An improved vacuum interrupter (1000) is disclosed. The vacuum interrupter (1000) includes end covers (1005) having a curved or looped portion (1022), which serves to connect a coil segment (1015) of the vacuum interrupter (1000) to a ceramic envelope (1010) of the vacuum interrupter (1000), and thereby help maintain a vacuum seal for the interrupter. The curved portion (1022) acts as a spring when the vacuum interrupter (1000) is exposed to heat, thereby absorbing any expansion or contraction in the length of the vacuum interrupter due to the heating or cooling. The curved portion (1022) also protects an end of the ceramic envelope (1010) from any build-up of metallic arcing products and eliminates the need for elaborate fixturing during assembly. Additionally, a guide (1045) may be affixed to the end cover (1005), the guide (1045) having ears (1302) which ride in a slot (1050) in a moving rod (1035) of the vacuum interrupter (1000), to thereby prevent a twisting of a bellows (1030) of the interrupter during a brazing process. Thus, no elaborate fixturing is necessary to prevent this twisting.
摘要翻译：公开了一种改进的真空断路器（1000）。真空断路器（1000）包括具有弯曲或环形部分（1022）的端盖（1005），其用于将真空断路器（1000）的线圈段（1015）连接到真空断路器的陶瓷外壳（1010）（1000），从而有助于维持断路器的真空密封。当真空断路器（1000）暴露于热量时，弯曲部分（1022）用作弹簧，从而由于加热或冷却而吸收真空断路器长度的任何膨胀或收缩。弯曲部分（1022）还保护陶瓷封套（1010）的端部免受金属电弧产物的任何积聚，并且在组装期间不需要精心的固定。另外，引导件（1045）可以固定到端盖（1005）上，具有耳环（1302）的引导件（1045）可以悬挂在真空断路器（1000）的移动杆（1035）中的槽（1050）中，，从而防止在钎焊过程中断路器的波纹管（1030）的扭转。因此，不需要精心的夹具来防止这种扭曲。

摘要： A make-before-break selector switch for use in high-voltage applications allows power to a load to be switched from a first power source to a second power source such that the second connection is made before the first is broken. The selector switch includes a blade coupled to a selector switch control such that the blade may be placed in a first position to electrically couple a first power source electrical contact to a load electrical contact and in a second position to electrically couple a second power source electrical contact to the load electrical contact. T-shaped and v-shaped blade implementations are examples of configurations that may be used.

摘要： Protection systems for electrical systems are described, where the electrical systems may include spot networks and/or grid networks. The various protection systems may be designed and used to detect and clear faults that may occur within the electrical systems. For example, a pair of Rogowski coils may be used to detect current along a conductors at their respective locations on the conductors, and to output corresponding signals to a multi-function, differential relay having multiple voltage and current inputs. By comparing the signals from the Rogowski coils, the differential relay may determine whether a fault exists at some point along the conductors and between the pair of Rogowski coils. Further, the relay may then, in response to the fault, trip a circuit breaker or other network protection device to address the fault.

摘要： A vacuum assembly including a vacuum interrupter (102) may be sealed with a compliant material (122) and/or rubber plugs (124), so that a cavity (126) is created and maintained within the assembly for use with a current exchange housing (118) and/or bellows, during operation of the vacuum interrupter (102). During vacuum molding of the vacuum assembly to encapsulate the vacuum assembly in an epoxy (128), a resulting pressure differential caused by the vacuum molding is prevented from disturbing the seal around the vacuum assembly, by way of a needle or tube (202) included in the seal. In this way, air from within the cavity (126) is allowed to escape, while the epoxy (128) is prevented from entering the cavity (126). Then, once encapsulation is complete, the vacuum assembly can be joined with an operating rod (108) and other components to complete a vacuum switching device (100).

摘要： Active crosstalk cancellation in a multi-phase system is achieved using a capacitive voltage divider (701, 705) for each phase in the multi-phase system. A voltage measurement is obtained for the desired phase and each additional phase of the multi-phase system. A product is generated for each additional phase by multiplying each additional phase voltage measurement by a corresponding predetermined constant. The product for each additional phase is subtracted from the voltage measurement of the desired phase.

摘要： A system for an AC electrical circuit includes an actuator (110), a source (115), and an actuator control system (120). The actuator converts current into a force to move contacts relative to one another to switch power on and off in the AC electrical circuit. The source operates to supply current to the actuator. The actuator control system is connected to the actuator and to the source to control the current to the actuator. The current to the actuator is independent of a voltage produced by the actuator during switching and a voltage at which the source operates.

摘要： A high-voltage loadbreak switch operates submersed in a dielectric fluid and may be configured to switch one or more phases of power using one or more phase switches. Each phase switch may include first and second stationary contacts. The first stationary contact may be connected to a phase of a high-voltage power source. Each phase switch also may include a non-stationary contact. The non-stationary contact may be placed in a first position to electrically couple the first stationary contact to the second stationary contact, and in a second position to decouple the first stationary contact and the second stationary contact. The region of motion of the first non-stationary contact between the first position and the second position includes an arcing region. The high-voltage loadbreak switch uses a fluid circulation mechanism to improve circulation of the dielectric fluid through the arcing region. To suppress arcing between different phases, a non-conductive baffle may separate different phase switches when more than one phase switch is used. A non-conductive baffle also may separate a phase from ground to prevent phase-to-ground arcing.
摘要翻译：高压负载断路开关操作浸没在电介质流体中，并且可以被配置为使用一个或多个相位开关来切换一个或多个电力阶段。每个相位开关可以包括第一和第二静止触点。第一固定触点可以连接到高压电源的相。每个相位开关还可以包括非静止触点。非静止触头可以放置在第一位置以将第一静触头电耦合到第二静触头，并且在第二位置中将第一静触头和第二静触头解耦。第一位置与第二位置之间的第一非固定接触的运动区域包括电弧区域。高压负载开关开关使用流体循环机构来改善通过电弧区域的介电流体的循环。为了抑制不同相之间的电弧放电，当使用多于一个相位开关时，非导电挡板可以分离不同的相位开关。不导电挡板也可以将相与地隔开以防止相对地电弧。
