    • Technologies are generally described for a nanocomposite polymer dielectric that may incorporate two types of nanoparticles and a polymer. One of the two types of nanoparticle may be a first, smaller nanoparticle, that may occupy spaces between larger second nanoparticles. Another of the two types of nanoparticle may be the second, larger, "high-κ" nanoparticle, which supports the overall dielectric constant of the material. In an applied electric field, the first, smaller nanoparticle may redistribute local charge to homogenize electric fields in the dielectric material, tending to avoid the development of "hot spots". Such a two-nanoparticle nanocomposite dielectric material may provide increased dielectric breakdown strength and voltage endurance in comparison with a nanoparticle dielectric which only contains a single type of "high-κ" nanoparticle.
    • 通常描述纳米复合聚合物电介质的技术,其可以掺入两种类型的纳米颗粒和聚合物。 两种类型的纳米颗粒之一可以是可能占据较大的第二纳米颗粒之间的空间的第一较小的纳米颗粒。 两种类型的纳米颗粒中的另一种可以是第二,更大的“高” 纳米颗粒,其支持材料的总体介电常数。 在施加的电场中,第一个较小的纳米颗粒可以重新分布局部电荷以使电介质材料中的电场均匀化,以期避免“热点”的发展。 与仅含有单一类型的“高α”的纳米粒子电介质相比,这种双纳米颗粒纳米复合材料介电材料可以提供增加的介电击穿强度和耐压性, 纳米粒子。
