湿污环境中零值绝缘子串发热特性的耦合场仿真及试验验证

Gaoya dianqi
为研究严重大雾天气下污秽零值绝缘子串的发热特性，文中建立了110 kV悬式瓷绝缘子串的电热耦合模型，分析了零值绝缘子在串中不同位置、不同污秽等级以及不同污秽分布对绝缘子串温度分布的影响特性，试验验证了仿真结果的有效性。研究表明：当盐密为0.04 mg/cm2的零值绝缘子串发热达到稳定时，串中零值绝缘子温度最低，而正常绝缘子温度明显增加，其增加的幅度受零值绝缘子的位置影响较大；污秽等级越高零值绝缘子串发热越严重，但串中零值绝缘子的温度随污秽等级提高其增加量最少，高压侧绝缘子温度增加较多 ...

黄土丘陵区油松人工林水热效应的研究

Shuitu Baochi Xuebao, 1995
研究了黄土丘陵区油松人工林内降不、相对温度、土壤水分、气温；地温等水热因子的变化规律，结果表明：林冠和枯枝叶层对降水截留作用强，林地仅获得７０％的林外降水量；月平均相对温度林内均低于林外，年平均相对湿度林内较林外低６．０％；林地土壤水分环境不良，水分恢复能力也较；林分对各月气温影响程度不同，年平均气温林内高于林外；林内土壤温度及其较差均低于林外，枯枝落叶层对土壤温度影响明显。
