Abstract

This study investigates the effects of absorbed water and volatile compounds on measurements of the electrostatic breakdown field strength. Comparisons are made between sets of pristine samples, ones that underwent a thorough vacuum bake out, and ones subsequently exposed to humid conditions to determine how quickly the samples reverted to an unbaked state. Specifically, we compared signatures related to electrostatic breakdown (electrostatic breakdown field strength, frequency of pre-breakdown arcing, and flashover) and images of the arc damage sites. The work reports results for three prototypical polymeric dielectric materials: low density polyethylene (LDPE), polyether-etherketone (PEEK), and Nylon 66, listed in order of decreasing hydrophobicity. Electrostatic breakdown strength was seen to change linearly with effective exposure time; hydrophobic LDPE and intermediate PEEK increased, while more hydrophilic Nylon 66 decreased. Similar trends were observed for the number of pre-breakdown arcs (DC partial discharges) versus effective exposure time.

挥发性化合物对聚合物击穿场强测量的影响

本文研究了吸附水和挥发性化合物对静电击穿场强测量的影响。将两组原始样品进行比较，一组经过彻底的真空烘烤，另一组随后暴露在潮湿条件下，以确定样品恢复到未烘烤状态的速度。具体来说，我们比较了与静电击穿相关的特征(静电击穿场强、击穿前电弧频率和闪络)和电弧损伤部位的图像。本工作报告了三种典型聚合物介电材料的结果:低密度聚乙烯(LDPE)、聚醚酮(PEEK)和尼龙66，按疏水性递减顺序排列。静电击穿强度随有效曝光时间呈线性变化;疏水性LDPE和中间体PEEK增加，亲水性尼龙66减少。在击穿前电弧(直流局部放电)的数量与有效暴露时间之间也观察到类似的趋势。
