【摘要】

：

将LiNi0.8Co0.15Al0.05O2材料置于25℃、湿度40～50％的空气中,研究其存储性能.滴定、XRD及恒电流充放电等测试结果表明,经过60天存储后,材料表层Li2CO3含量随着存储时间由0.2353％线性增加至0.8423％,首次放电容量由184.5mAh/g降低至178.2mAh/g,且50次循环的容量保持率由90.84％降低至88.72％.

电感型避雷针防雷机理研究

雷击是导致输电线路跳闸的主要原因，新的防雷机理及防雷措施一直是国内外研究热点和难点。本文针对以降低雷电流陡度和幅值进而降低雷害事故的电感型避雷针开展了有限元分析、电磁暂态分析和滤波特性分析，以探索其防雷机理并评价其防雷效果。基于有限元分析建立了考虑电感型避雷针电感参数及分布电容参数的链式等效电路模型，并探索了等效电感和电容参数的影响因素。基于PSCAD/EMTDC 电磁暂态程序建立了输电线路耐雷性
