在分析现有生产调度策略和实际生产情况的基础上，提出一种基于周期性和事件驱动的具有冻结期的调度策略，研究并实现了一种有效的逆序启发式调度算法。 - The main work and conclusion for this paper is as following : according to the flashover test results of several kinds of iced insulators under positive voltage and negative voltage , this paper obtained : for the single porcelain insulator , the single glass insulator and the composite insulator bridged completely by icicle , the metal cathode ' s strong ability of emission electron is the primary reason that results in the lower negative flashover voltage ; the position difference of the high resistance district in method anode side results in that porcelain insulator cluster and glass insulator cluster have an evident effect of polarity ; when less ice and no icicle at the brim of the sheds , due to numerous non - polar arcs on the composite surface , the effects of polarity of composite insulator was lost using the test method of the average flashover voltage in the freezing period , dc flashover performances were investigated of several insulators with some typical structures and different material
本文的主要工作和结论如下：在人工气候室内，根据不同覆冰绝缘子正、负极性下的闪络试验结果，得出负极性电弧金属阴极的强电子发射能力造成了单片瓷、玻璃绝缘子及被冰凌桥接的合成绝缘子有较低负极性冰闪电压；正极性电弧金属阳极侧产生高电阻区所处位置的差异使得瓷和玻璃绝缘子串具有明显的极性效应；覆冰较少时，合成绝缘子表面出现数量较多的非极性电弧使合成绝缘子无极性效应。利用覆冰期内平均闪络电压的试验方法，对不同材质和结构的绝缘子在覆冰、低气压和污秽共存环境中的直流闪络特性进行了研究。试验结果表明，直流平均闪络电压随着海拔的升高、覆冰量的增加以及污秽度的增加而降低，且其特征指数与绝缘子结构、覆冰量、覆冰状态、污秽度等有关。
