摘要： A tank for a dead tank circuit breaker includes a body having an interior volume defined by an interior surface. A particle trap structure includes a pair of recessed surfaces in a bottom portion of the interior surface. Each recessed surface is disposed in spaced relation with respect to the interior surface so as to define a channel. A raised surface is spaced from the recessed surfaces and separates the recessed surfaces. The channels are constructed and arranged to trap foreign particles in the interior volume, with the raised surface being constructed and arranged to raise an electric field in the interior volume to be above the channels so as to eliminate electrical activity that would affect the particles in the channels.

摘要： A method and device for operating a fluid-insulated electrical apparatus. The insulation fluid of the electrical apparatus includes at least two components. The method includes the step of determining a physical state of the insulation fluid by measuring at least three measurement variables with sensors. The method further includes the step of deriving trend variables indicative of changes over time for the measurement variables and/or for characterizing variables. These characterizing variables are derived from the measurement variables by using a relating equation, such as an equation of state, and are also indicative of the physical state of the insulation fluid. By testing for specific patterns of the trend variables, an operating state of the electrical apparatus is determined. The possible operating states correspond to specific and distinguishable non-fault and fault scenarios for the electrical apparatus. Thus, operating states can be distinguished and trouble-shooting in case of a failure is simplified.

摘要： A three-phase vacuum interrupter switch assembly for power distribution systems comprises an outer case having at least one window and containing a plurality of component assemblies. The case interior is preferably free of oil and/or SF6 gas. Each component assembly comprises three internal disconnect switch assemblies, three vacuum interrupter bottle switch assemblies and three ground switch assemblies. Each vacuum interrupter bottle switch is coupled in electrical series with a corresponding internal disconnect switch assembly. Because the open/closed state of a bottle switch is not directly observable owing to its sealed interior, a direct visible indication of the state of the three-phase vacuum interrupter switch assembly is provided by a visually detectable contact rod of the corresponding internal disconnect switch that is visible through the case window. To prevent potentially serious damage caused by arcing between the contacts of the internal disconnect switch, the internal disconnect switch is prevented from opening or closing when the bottle switches are closed.When the component assembly is deactivated, some residual current may still remain. The ground switch assembly associated with the component assembly grounds such residual current as part of the deactivation process so that it is safe to have maintenance work performed. An interlocking mechanism ensures that the disconnect switch assembly, vacuum interrupter bottle switch assembly and ground switch assembly of each component assembly are opened and closed in a sequence that ensures proper and safe operation.
摘要翻译：用于配电系统的三相真空断路器开关组件包括具有至少一个窗口并且包含多个部件组件的外壳。壳体内部优选不含油和/或SF 6气体。每个组件组件包括三个内部断开开关组件，三个真空断路器瓶开关组件和三个接地开关组件。每个真空断路器瓶开关与相应的内部断开开关组件电连接。因为瓶盖开关的打开/关闭状态由于其密封的内部而不能直接观察到，所以三相真空断路器开关组件的状态的直接可视指示由相应的内部断开开关的可视检测的接触杆提供这是通过案例窗口可见的。为了防止内部断开开关的触点之间的电弧引起的潜在的严重损坏，当瓶盖关闭时，内部断开开关可防止打开或关闭。当组件组件被禁用时，可能仍然存在一些剩余电流。与组件组件相关联的接地开关组件将剩余电流作为停用过程的一部分进行接地，以便进行维护工作是安全的。互锁机构确保每个组件组件的断路开关组件，真空断路器瓶开关组件和接地开关组件以确保正确和安全操作的顺序打开和关闭。

摘要： A gas reclaiming equipment capable of separating SF6 gas from a mixed gas efficiently and shortening reclaiming work under reduced pressure. A gas separation equipment is provided between a gas insulated equipment and a gas liquefaction system. The gas separation equipment separates nitrogen gas from the mixed gas, and concentrates SF6 gas. Only SF6 gas is sent into the gas liquefaction system. The gas separation equipment uses pressure swing adsorption using an adsorbent with selective adsorption. Moreover, a buffer tank for storing mixed gas is provided between the gas separation equipment and the gas insulated equipment. The buffer tank and the gas liquefaction system are connected by a reflux-line. The reflux-line refluxes the gas in a gas phase in the gas liquefaction system to the buffer tank. Furthermore, the gas separation equipment is connected to a storage tank. The storage tank accumulates the nitrogen gas separated with the gas separation equipment. The adsorbent to adsorb SF6 gas is enclosed in the storage tank for exhaust gas. To absorb decomposed gas, the filter has an adsorbent of the chemisorption type. The adsorbent has of a metal hydrate.
