Abstract

The fast-switching frequency, high slew rate, and high voltage provided by the advanced power electronics inverters promote pa discharge (PD) in the turn-to-turn insulation in the inverter-fed motors. Polymer nanocomposites have been drawing the attention of researchers as PD-resistant insulating materials in inverter-fed motors. The high-volume fraction of interphase between the metal oxide nanoparticles and polymers improves the dielectric properties of the enameled wire. In this article, a numerical model of the electric field distribution of polymer nanocomposites is developed based on the dielectric properties of the interphase between the nanoparticles and metal oxides. The relative permittivity of the interphase region is first determined from the thickness and volume fraction of nanoparticles. A numerical model of polymer nanocomposites is developed in COMSOL Multiphysics to determine the electric field distribution for various interphase relative permittivity driven by the volume fraction of nanoparticles and interphase thickness. This numerical model is useful in designing polymer composites to effectively mitigate PD in inverter-fed motor windings.

相间介电性能对聚合物纳米复合材料电场分布的影响

先进的电力电子逆变器提供的快速开关频率、高转换率和高电压促进了逆变器供电电机匝间绝缘中的pa放电（PD）。聚合物纳米复合材料作为一种抗pd的绝缘材料，在逆变电机中得到了广泛的应用。金属氧化物纳米颗粒与聚合物间相的高体积分数改善了漆包线的介电性能。本文基于纳米聚合物与金属氧化物界面的介电特性，建立了聚合物纳米复合材料电场分布的数值模型。相间区的相对介电常数首先由纳米颗粒的厚度和体积分数确定。在COMSOL Multiphysics中建立了聚合物纳米复合材料的数值模型，以确定纳米颗粒体积分数和界面厚度驱动下不同界面相对介电常数的电场分布。该数值模型可用于设计聚合物复合材料以有效减轻逆变电机绕组中的局部放电。
