高海拔地区10kV合成绝缘子覆冰闪络特性

AC Flashover Performance and Voltage Correction of Iced 10 kV Composite Insulator in High Altitude Area

根据在重庆大学多功能人工气候室内对高海拔条件下 10 k V合成绝缘子的覆冰试验研究结果 ,分析了覆冰量、覆冰状态及海拔高度 (或气压 )对 10 k V合成绝缘子最低交流闪络特性的影响及闪络过程 ,提出了 10 k V合成绝缘子在高海拔和覆冰分别及综合作用下闪络电压的校正公式。

Based on the test results carried out on 10 kV composite insulators in the multi-function artificial climate chamber of Chongqing University, this paper discusses the effects of atmospheric pressures altitudes, and ice amount accreted on the insulator on its minimum AC flashover voltages, and analyzes the flashover process of the 10 kV composite insulator in icing and low pressure conditions, and therefore puts forward the correction method of flashover voltage.
