| 摘 要： | 分析了聚酯薄膜电击穿可能的模型，如本征击穿模型和电一机械击穿模型，估算了两种模型下常用聚合物介质的临界击穿场强。实验研究了平板电极结构下10μm级聚酯薄膜的自击穿电压，得出了聚酯薄膜的临界击穿场强450-500kV／mm。实验结果与理论计算值比较表明：本征击穿模型下的聚酯薄膜临界击穿场强都远小于实验结果，电～机械击穿模型下聚酯薄膜临界击穿场强大于实验结果。

| Abstract: | Numerical analysis was carried out based on the intrinsic breakdown model and the electro-mechanical breakdown model. The self-breakdown voltage characteristic of the polyester foil was measured in a plane-plane electrode arrangement with DC voltage. The thickness of the polyester foil varied among 9, 12, 15 and 18 μm. Experimental results show the average strength of the polyester foil. The comparison between the theoretical analysis and the experimental results was presented. The results show that the critical breakdown strength of the polyester foil in the intrinsic breakdown model is far lower than the experimental results, and the critical breakdown strength of the polyester foil in the electro-mechanical breakdown model is higher than the experimental data of the polyester foil. |
