固体绝缘开关柜隔离开关模块绝缘特性研究

Gaoya dianqi
在固体绝缘开关柜的研发过程中，高绝缘水平的优化设计是其安全可靠运行的保障。文中设计了一种适用于固体绝缘开关柜的隔离开关模块，并通过试验验证了其在75 kV（合闸）、85 kV（断口）雷电冲击电压下的绝缘性能，满足国家标准要求；但当雷电冲击电压等级提高到西班牙、澳大利亚等地区标准要求的95 kV时，型腔内接地端部处发生沿面放电。采用有限元软件对其进行电场仿真与分析，由仿真结果得知型腔内接地端部空气场强发生畸变，原因在于屏蔽罩与环氧内层的绝缘距离不足，造成气固交界面的空气场强超过临界值，引发沿面放电 ...

基于遥感生态指数改进模型的沱江流域生态环境质量时空变化及驱动力研究

Shuitu Baochi Xuebao
[目的] 沱江流域面临严重的水土流失、水环境污染和土壤侵蚀等生态环境问题,开展流域生态环境质量评价对推动长江上游生态环境保护和流域社会经济高质量可持续发展具有重要意义。[方法] 基于谷歌地球引擎平台,选取2000—2020年的Landsat遥感影像,以绿度、湿度、热度、干度、生物丰度指数构建生态环境质量评价模型,采用变异系数、一元线性回归和空间自相关分析方法对流域内生态环境质量的时空演变格局进行分析,并运用最优参数地理探测器模型(optimal parameter geographic detector
