摘要
根据在人工气侯室内对悬式绝缘子XP—7,XWP2—7,DC—Ⅱ—16和支柱绝缘子ZS1—35—400,ZWS1—35—400的直流污闪试验结果,得到了直流闪络电压与气压和盐密的关系,并对不同结构绝缘子的污闪特性进行了分析,提出了表征直流污闪电压随气压降低而下降的特性指数n值的选取原则,并与交流下的结果进行了比较和分析。
In this paper, the relation between the DC polluted flashover voltage of 6 kinds of insulators and atmospheric pressure, ESDD was presented according to the test results of suspension insulators XP-7, XWP2-7, DC-2# 16 and support insulators ZS1-35-400 , ZWS1-35-400 conducted in artificial climate chamber. The contaminated flashover characteristics of various structure insulators have been analysed . The selective principle of characteristic exponent n which reflects the decrease of polluted flashover voltage with the ecline of pressure was proposed. The test results under DC were compared with those under AC.
