Abstract

ABSTRACT This paper reveals the high-voltage insulation properties – namely the dielectric constant, dissipation factor, breakdown strength, and voltage – of epoxy resin samples of various thicknesses containing the microadditives albite, potassium feldspar, lithium glass, and zinc glass in different concentrations. 0.1 wt% KAlSi3O8 ceramic powders as fillers in 1 mm epoxy composites designed for insulation is taken as the choice for highest breakdown strength 36.6491 kV/mm. After that, 5 wt% Li-Bi-B-O glass at 35.4687 kV/mm, 10 wt% Zn-Bi-B-O glass at 35.0432 kV/mm, and 10 wt% NaAlSi3O8 at 33.6504 kV/mm. The increase of thickness more than 1 mm is not recommended in the practical application due to the decrease of breakdown strength. Multi-layer thin structure is recommended for insulation purpose.

陶瓷-玻璃复合材料的高压绝缘和介电性能
摘要本文揭示了含有不同浓度的微添加剂钠长石、钾长石、锂玻璃和锌玻璃的不同厚度环氧树脂样品的高压绝缘性能,即介电常数、耗散因子、击穿强度和电压。选择0.1 wt%的KAlSi3O8陶瓷粉末作为1mm环氧树脂复合材料中的填料,设计用于绝缘,以获得最高击穿强度36.6491kV/mm。之后,在35.4687kV/mm下加入5wt%的Li-Bi-B-O玻璃,在35.0432kV/mm下添加10wt%的Zn-Bi-B-O玻璃,在33.6504kV/mm下放入10wt%的NaAlSi3O8。在实际应用中,由于击穿强度降低,不建议厚度增加超过1mm。出于绝缘目的,建议采用多层薄结构。
