摘要： A method is provided that includes providing a resin in liquid form. The resin can be partially cured, and subsequent to partially curing the resin, the resin can be mixed with filler particles. The resin and filler particles can be mixed, say, in a planetary mixer, and can be exposed to an ambient pressure less than atmospheric pressure during mixing. Subsequent to mixing the resin and filler particles, the resin can be fully cured. The fully-cured resin can be disposed between first and second conductive components configured to be maintained at different potentials, such as between a phase conductor and a ground conductor.

摘要： A plasma gun with two gap electrodes on opposite ends of a chamber of ablative material such as an ablative polymer. The gun ejects an ablative plasma at supersonic speed. A divergent nozzle spreads the plasma jet to fill a gap between electrodes of a main arc device, such as an arc crowbar or a high voltage power switch. The plasma triggers the main arc device by lowering the impedance of the main arc gap via the ablative plasma to provide a conductive path between the main electrodes. This provides faster triggering and requires less trigger energy than previous arc triggers. It also provides a more conductive initial main arc than previously possible. The initial properties of the main arc are controllable by the plasma properties, which are in turn controllable by design parameters of the ablative plasma gun.
摘要翻译： 等离子体枪，具有两个间隙电极，位于烧蚀材料室（例如可消融聚合物）的相对两端。 枪以超音速弹出烧蚀等离子体。 扩散喷嘴扩展等离子体射流以填充主弧装置的电极之间的间隙，例如电弧撬棒或高压电源开关。 等离子体通过消融等离子体降低主电弧间隙的阻抗来触发主电弧装置，以在主电极之间提供导电路径。 这提供了更快的触发，并且比以前的电弧触发要求更少的触发能量。 它还提供比以前更可能的更导电的初始主弧。 主弧的初始特性可以通过等离子体性质来控制，这些等离子体性质又可由烧蚀等离子枪的设计参数控制。

摘要： Provided are compositions that include a dielectric matrix material defining multiple voids of substantially uniform respective dimension and configured as a substantially uniform array. The voids may be configured such that charges that accumulate at surfaces of at least some of the voids when the composition is immersed in a uniform external electric field interact with charges that accumulate at surfaces of at least others of the voids to cause movement of the respective charges in a direction having a component transverse to the electric field. Hollow particles may be disposed within respective voids of the array of voids defined by the matrix material, and particles, such as, for example, ceramic, varistor, and/or inorganic dielectric particles, may be incorporated within the matrix material. Associated devices are also provided.
