摘要
在人工气候室内模拟不同气象条件对不同形式绝缘子串进行了覆冰直流闪络特性研究。根据试验结果分析了"V"形串布置方式和插花形布置方式绝缘子串在不同串长和不同污秽下与垂直串的覆冰直流闪络特性,结果表明"V"形串和"3+1"形插花方式绝缘子有利于提高绝缘子直流冰闪电压。
Laboratory investigations on DC flashover performances of different types of ice-coated string insulators under different climate conditions simulated in the artificial climate chamber were carried out. Based on the DC flashover test results in the artificial climate chamber, The DC icing flashover performance of V-type string and＂ 3＋1＂ alternative unit pattern under different string length and pollution level was analyzed. The results indicated that the V-type string and＂ 3＋1＂ alternative unit pattern was advantageous to increase DC icing flashover voltage.
