In accordance with two kinds of preliminary hydrophobic surface-hydrophobic and hydrophilic surface, wettability models under different temperature have been investigated.
结果发现:低温雾中复合绝缘子的湿润模型是由湿润、过渡、烘干等过程重复组成,而室温下雾的强冷凝作用导致表面持续湿润并放电,湿润或烘干过程并不明显,使得湿润模型可仅存在过渡过程;此外,憎水性有效地抑制了泄漏电流工频分量的幅值,即有效地减轻了污层的湿润程度并延缓了达到第一次饱和湿润的时间,最终使得耐受电压(耐受时间)要高于(长于)丧失憎水性的情况。
It analyzes the strength theory and mathematic model in the mechanical property and project feature of the loess at home and abroad since fifty years,combining with the condition and require of the engineering and brings forward easy and operational wet-chemical model to guide the actual project construction.
从对比分析半个世纪以来,国内外关于黄土的力学性质和工程特性研究中所采用的强度理论和数学模型出发,结合工程实际的条件和需要,提出建立简单实用的湿化模型,用来指导实际工程建设。
