This study measures the voltage at which flashover occurs in compressed air for a variety of dielectric materials and lengths in a uniform field for DC voltages up to 100 kV. Statistical time lag is recorded and characterized, displaying a roughly exponential dependence on breakdown voltage. Of the materials tested, acrylic is observed to be the most resistant to flashover. These data are intended to facilitate the design of compressed-air insulated high voltage systems as an alternative to SF6 insulated systems.

各种介质用压缩空气中的高压直流表面闪络

本研究测量了在直流电压高达 100 kV 的均匀场中，各种介电材料和长度在压缩空气中发生闪络时的电压。统计时间滞后被记录和表征，显示对击穿电压的大致指数依赖性。在所测试的材料中，观察到丙烯酸是最耐闪络的。这些数据旨在促进压缩空气绝缘高压系统的设计，以替代 SF6 绝缘系统。
