提出了一种估算三相点周围气体局部放电起始条件的新方法。实验证实了基于Paschen曲线和固体绝缘体与气体之间的界面电位分布沿着的方法的有效性在空气中在室温下。估算了室温下不同压力下空气和SF6气体中局部放电的起始条件以及饱和温度和大气压下低温氮气和氦气中局部放电的起始条件。在此基础上对局部放电强度进行了讨论。© 2003 Wiley Periodicals，Inc. Electr Eng Jpn，144（1）：1-11，2003;在线发表于Wiley InterScience（www.interscience.wiley.com）。DOI 10.1002/eej.10175
A new method of estimating partial discharge onset conditions in gases around a triple junction is proposed. The effectiveness of the method based on the Paschen curve and the potential distribution along the interface between a solid insulator and gas is confirmed experimentally in air at room temperature. The partial discharge onset conditions in air and SF6 gas under different pressures at room temperature and in cryogenic nitrogen and helium gases at saturation temperature and atmospheric pressure are estimated. The partial discharge intensity is discussed on the basis of the proposed method. © 2003 Wiley Periodicals, Inc.
