摘要

根据在重庆大学多功能人工气候室内对110 kV FXBW-110/100复合绝缘子的耐压法试验结果，指出复合绝缘子的耐压时间应至少为15分钟，在正常情况下，所有冻水电导率为300 /spl mu/S/cm的复合绝缘子均能承受工作电压。本文分析了大气压力对耐压和闪络电压的影响。由于放电路径具有较高的随机性，因此大气压力对覆冰绝缘子闪络电压的影响具有较高的随机性。

AC withstand voltage performance of 110 kV iced composite insulators

Based on the test results performed on 110 kV FXBW-110/100 iced composite insulators with a withstand voltage method in the multifunction artificial climate chamber of Chongqing University, this paper indicates that the withstand duration for an iced composite insulator should be at least 15 minutes, and that at normal conditions, all the tested insulators iced with a freezing water conductivity of 300 /spl mu/S/cm can withstand the service voltage. This paper analyzes the effect of the atmospheric pressure on withstand and flashover voltages. Because the discharge path has a high randomness, the effect of atmospheric pressure on flashover voltages of iced insulators has a high randomness.
