Gaoya dianqi, 2004 基于介损在线监测数据的变化规律,建立了数据趋势模型,提出了基于小波变换和形态滤波的两种趋势提取方法,两种方法均能有效地克服数据中周期性因素和各种加性噪声的影响,还原数据的基本变化趋势。通过实例验证了这两种方法的有效性。

Gaoya dianqi温度是影响电缆附件绝缘性能的关键因素。文中分析了不同硬度硅橡胶材料的红外光谱和玻璃化转变特性，测试分析了高低温环境-40~+60 ℃下不同硬度电缆附件硅橡胶材料的介电性能、电阻特性和击穿特性；从微观层面，通过计算分析不同温度硅橡胶的自由体积和均方位移等参数，揭示了高低温对硅橡胶材料绝缘性能的影响机理。研究表明，随着温度升高，硬度40 HA硅橡胶相对介电常数从3.66下降到3.22，下降约12%，相比而言90 HA硅橡胶下降约15%；两者介质损耗角正切值在-40~+60 ℃范围内均基本不变，平均值分别为1.
