Dianci bileiqi接地装置的冲击接地电阻对线路的耐雷水平有很大的影响，因此，对接地设备进行基于降阻效果的优化设计是非常有必要的。研究发现在接地极上加装针刺状导体能够改善接地装置冲击特性，文中基于薄壳理论建立了考虑土壤火花击穿特性的接地装置冲击特性有限元模型，然后分析了在水平接地体上添加针刺的降阻机理，最后采用仿真软件研究了针刺导体的位置、间距和角度对冲击接地电阻的影响。研究结果表明：针刺导体的位置、间距、角度与冲击接地电阻之间的关系并非线性，而是存在最优值。在水平接地体长度为15 m、针刺长度为1 m的情况下 ...

Gaoya dianqi作为高压电缆终端中的常用填充剂，聚异丁烯（polyisobutylene，PIB）的高温裂解机理尚不明晰。文中利用ReaxFF反应分子动力学软件，获得了聚异丁烯在2 400 K和3 000 K下的裂解产物及其生成路径。研究结果表明，3 000 K下PIB高温裂解产物体积分数均高于2 400 K，表明老化温度升高会加速PIB的裂解及各特征气体的生成，且H2及CH4可作为PIB高温裂解的主要特征产物，并在473 K下开展了PIB热老化验证了数值模拟结果的有效性。同时，为探究影响PIB产气特性的关键因素 ...
